Snapshot#
A light Friday-into-Saturday window: no new frontier or open-weight model shipped. What moved was the harness layer and the indexes. Artificial Analysis re-based its Coding Agent Index, and the new version puts the frontier tie at 58, with costs from $1.51 to $44.22 per task among configurations scoring 48 or more. Claude Code and Antigravity both shipped ways to run parallel workers from one request. Cloudflare open-sourced its Workers-based agent browser, and the llama.cpp team followed the 1.0 tag with desktop apps and an MoE expert cache flag.
- AA Coding Agent Index v2.1 (2026-11-13 18:04 CST, AA post): moves to FrontierCode-AA 2.0 and Terminal-Bench 4.1. Claude Code + Fable 5.2 (xhigh) 58.5 at $15.47/task, Claude Code + Fable 5.2 (high) 58.2 at $7.51, Codex + GPT-6.1 Sol (max) 52.2 at $1.51.
- Claude Code Projects redesign (beta, select Pro and Max users on cloud sessions): a coordinator splits a goal into parallel threads, each a full Claude Code cloud session on its own branch, with shared project memory.
- Antigravity Dynamic Workflows (
/run-workflow, AI Pro and Ultra): the agent writes a Python script that fans out subagents with JSON-Schema results, and asks you to approve the script before it runs. - Cloudflare Kitesurf (repo, Apache-2.0): a stateless agent browser on Workers with Chrome DevTools Protocol support, so Puppeteer connects to it. Self-hosting needs a Workers Paid plan.
- Llama desktop apps plus the llama.cpp v1.0 post: a 1 MB Mac menu-bar app (and Windows tray app) that serves local models on an OpenAI-compatible endpoint at
localhost:9931. The v1.0.0 notes add an MoE expert cache that Daniel Han says you turn on with--moe-cache-mib N. - DeepSeek App capabilities via API (2026-11-13): server-side web search, file parsing, URL reading, safety checks, plus standalone OCR, ASR and TTS endpoints, billed as tool fees on top of tokens.
- Cursor security incident update (2026-11-13): root cause was an access key Cursor had issued to Fireworks. Coding-agent traces (mostly 2025, non-Privacy-Mode) were copied, and less than 0.01% of customers had API credentials exposed in them.
- Claude Code 2.1.325 fixes the third-party-gateway context failure that 2.1.323 introduced, plus a security fix in zstd response decoding.
Do this today: pull up the Coding Agent Index v2.1 cost chart, find your harness and model, then run 20 of your own tasks with Fable 5.2 at medium against your current default and compare cost per solved task.
Frontier and open-weight models#
No new frontier or open-weight model launched in the window. The model-side news is new index data, an API capability release from DeepSeek, distribution changes and quant updates.
- Update Claude Fable 5.2 closed frontier, pricing and evals.
- Price: $8 / $40 per 1M input/output on OpenRouter, matching what Arena reports as a cut from $10 / $50.
- Index view: still #1 on the AA Intelligence Index at 64.6 (max) for $26.54 per task. On the new Coding Agent Index (§3) it ties Opus 5.5 at 58, but its max setting scores lower (55.7) than high (58.2) at almost 6x the cost.
- Operator data point: Garry Tan ran 52 coding tasks in Claude Code 2.1.322: Fable 5.2 solved 82.7% against Opus 5.5's 84.6%, at 2.80x the cost per solved task. A small sample with no harness change, but it points the same way as AA's max-vs-high result.
- Builder take: if you moved to Fable at max, step down to high or medium and re-measure. The extra spend is not buying score on either index.
- News DeepSeek App capabilities via API CN lab, API capabilities (announcement, 2026-11-13 08:24 CST).
- What: web search (including search during multi-step reasoning), file input (PDF, Office, images), automatic URL reading and input/output safety checks, with tool calls and context assembly handled server-side. Search, Fetch, OCR, ASR and TTS are also standalone APIs.
- Protocols: Messages, Responses and Chat Completions; there is an Anthropic-format endpoint (
api.deepseek.com/anthropic/v1/messages), per the chatbot guide. - Cost: tool usage fees on top of token charges; the fee table is on the news page. DeepSeek says public-facing apps must enable safety checks.
- Open source: a frontend demo that can import DeepSeek conversation history is linked from the guide.
- Builder take: if you hand-rolled search and file parsing around DeepSeek V4.1 Flash, you can now delete that code and pay per tool call instead. Compare the fees with your current search API before you switch.
- Context DeepSeek V4 Pro 0813 open weights, newly indexed (MIT, weights from 2026-08-13; HN 24). AA added a High evaluation on 11-13. Its model page puts the Max variant at 23 on the Intelligence Index for $1.77 per task and 19.7 minutes per task, calling it "below average" against open models of its size. The HF repo is the August release, not new weights. V4.1 Flash 1017 (32.6, $0.60 per task) is still the DeepSeek model to use.
- News Ling 3.2 Flash (free) CN lab, free endpoint (inclusionAI, added to OpenRouter 2026-11-13 11:45 CST). A hybrid reasoning model with text and image input, a 1M context, up to 200 images per request, and tool calling and structured outputs. Its one provider is Ant Digital. No weights on inclusionAI's HF org at check time and no AA evaluation, so treat it as a free endpoint to test, not an open-weight release.
- Update Tencent Hy4 CN lab, usage mover is #2 by weekly tokens on OpenRouter rankings (19.8T, +181% week on week) at $0.417 / $1.25 per 1M. On AA it scores 34.6 on the Intelligence Index for $1.03 per task, and AA reports it #3 on the Cyber Index (58%) and #1 on CWE-Bench-AA. Not open weights.
- Update Unsloth Qwen3.8-27B Dynamic v3.1 open weights, local quants (GGUFs, Apache-2.0; HN 190). Most 2-bit to 6-bit quants were re-uploaded with Unsloth's updated method. Unsloth says they are 5–10% more accurate at the same size on Terminal-Bench 2.1, DeepSWE v1.1 and others (their own runs, 256K context for agentic benchmarks). UD3 3-bit quants were not changed. The page also disputes a third-party quant comparison (ISTA GSQ-RCO), arguing that 14 trials against one change the result. These are vendor numbers on both sides.
- Update Inkling 2 Small: end-to-end 4-bit training open weights, training detail (Thinking Machines; HN). The recipe: NVFP4 forward passes in the expert layers from the first pretraining step to the final RL rollout, MXFP8 backward passes with stochastic rounding, and quantized GPU communications. They report an 8% wall-clock speedup in pretraining on GB300, and say shipping the quantized checkpoint needed no calibration. Worth reading if you fine-tune MoE models on Blackwell.
- Still open ERNIE 5.5 Flash CN lab, weights promised. Weights are still expected by 11-25. llama.cpp PR #31925 is still the thing to watch. The preview stays free on OpenRouter.
- Still open Qwen4-Max preview thin. Still no model card, price or weights; a third-party eval page is the only new artifact.
- Not printed: Gemini 4 "Suiso" in Arena's weekly recap (no Google primary found), Ripple-65B Preview (covered before; only a webinar post today), Tencent Hy Realtime (no primary opened), NVIDIA GR00T 2 (robotics, X repost only), Runway Praxis-1 (open robot model, repo, Apache-2.0, outside core scope).
Pareto frontier (quality vs $/token vs $/task vs session economics)#
AA Coding Agent Index v2.1 (page data read 07:55 CST; materialized 2026-11-14 05:25 CST; cost is pay-per-token API cost per task, cache discounts included):
| Harness + model | Index | $ per task | Time per task | Cache hit |
|---|---|---|---|---|
| Claude Code + Fable 5.2 (xhigh) | 58.5 | $15.47 | 53.3 min | 94% |
| Devin Fusion CLI (Opus 5.5 max + GPT-6 Luna high) | 58.4 | $8.75 | 54.9 min | 87% |
| Claude Code + Fable 5.2 (high) | 58.2 | $7.51 | 31.3 min | 94% |
| Claude Code + Opus 5.5 (max) | 58.2 | $12.61 | 65.3 min | 95% |
| Claude Code + Sonnet 5.5 (max) | 56.3 | $11.40 | 86.8 min | 95% |
| Claude Code + Fable 5.2 (max) | 55.7 | $44.22 | 129.5 min | 93% |
| Antigravity CLI + Gemini 4 Carbon (high) | 55.5 | $7.13 | 33.6 min | 95% |
| Codex + GPT-6 Astra (max) | 53.1 | $7.63 | 26.0 min | 93% |
| Claude Code + Fable 5.2 (medium) | 53.0 | $2.89 | 15.1 min | 92% |
| Codex + GPT-6.1 Sol (max) | 52.2 | $1.51 | 21.9 min | 93% |
| Codex + GPT-6.1 Terra (max) | 48.6 | $1.53 | 28.1 min | 97% |
| Kimi Code CLI + Kimi K3.1 Pro (open) | 48.6 | $2.94 | 41.8 min | 96% |
| Antigravity CLI + Gemini 4 Argon (high) | 45.5 | $6.84 | 37.7 min | 87% |
| Opencode + GLM-5.3 (max, open) | 40.1 | $5.41 | 52.8 min | 97% |
| Muse Code + Muse Ember (max) | 39.7 | $0.22 | 19.9 min | 96% |
| DeepSeek Harness + V4.1 Flash 1017 (max, open) | 36.8 | $0.32 | 31.4 min | 95% |
- Update v2.0 had Claude Code + Opus 5.5 on top at 61.7 (11-13 brief). v2.1 swaps in FrontierCode-AA 2.0 and Terminal-Bench 4.1, and Latent Space says average scores fell about 5 points. Don't compare v2.0 and v2.1 numbers directly. GitHub Copilot Fusion was not in the v2.1 data at read time.
- Pareto read: AA puts Fable 5.2 at medium, high and xhigh on the Pareto line. Below them, Codex + Sol at $1.51 is the cheap point at 52, and Muse Ember ($0.22) and DeepSeek V4.1 Flash ($0.32) are the floor near 37–40. Max effort is off the line for Fable: 55.7 at $44.22.
- Open-weight points: Kimi K3.1 Pro in Kimi Code CLI (48.6, $2.94) ties Terra in Codex on score. GLM-5.3 in OpenCode costs more ($5.41) for less (40.1). DeepSeek V4.1 Flash in DeepSeek Harness is the cheapest open point.
- Token efficiency: every configuration sits at 87–97% cache hit. The two lowest are Devin Fusion and Antigravity + Argon (87%), which matters if your provider charges for cache misses differently. On the general AA Intelligence Index, output tokens per task range from about 52K (GPT-6 Astra max) and 68K (Sol) to 274K (Fable 5.2 max) and 285K (Sonnet 5.5 max).
- Index disagreements:
- Fable 5.2 vs Opus 5.5: AA's coding index has them tied at 58. Agent Arena has Fable #1 at +30.4% net improvement, about 1.6x Opus 5.5, with the lead growing past 16 turns. Garry Tan's 52-task run has Opus slightly ahead on solve rate and far cheaper per solved task. Arena counts real sessions, AA counts a fixed suite, and the Tan run is one person's task set.
- Proactivity: the new Agent Initiative Benchmark has GPT-6.1 Sol beating Fable 5.2 at $0.11 vs $1.87 per task (per the author's thread; 12 models, synthetic company).
- Reasoning effort as a cost lever: on the HF Harness Leaderboard, high effort makes DeepSeek-V4.1-Flash 28% more expensive with no gain beyond noise across five coding agents. Same lesson as Fable max above: measure effort levels; don't default to the top one.
- AA Intelligence Index v5 (Context): unchanged at the top since 11-13: Fable 5.2 64.6 ($26.54), Carbon 60.0 ($5.48), Opus 5.5 59.1 ($10.04), Astra 56.9 ($6.24), Sol 54.6 ($1.27), Hydrogen xhigh 53.9 ($3.16), Terra 51.3 ($0.96), Kimi K3.1 Pro 46.5 ($3.68, top open). New evaluations on 11-13: Gemini 4 Argon (Medium) and DeepSeek V4 Pro 0813 (High).
- Session economics: OpenRouter weekly tokens through 11-13: DeepSeek V4.1 Flash 1017 56.9T, Hy4 19.8T (+181%), DeepSeek V4.1 Flash 15.8T, GLM 5.3 Flash 11.8T, GPT-6 Luna 7.53T, Opus 5.5 6.99T. The top four by volume are all Chinese-lab models. The cost-per-session panel is still client-rendered and unreadable from a fetch.
- Routing for cost per solved task: AWS published a NeMo Switchyard + LiteLLM sample that routes coding-agent requests between a capable and a cheap model based on recent tool activity, with benchmark runners that report cost per solved task. AWS labels it experimental and not for production; the stage router needs the full conversation history on every request.
Coding CLIs/IDEs/harnesses#
Times converted from UTC to CST.
- News: Claude Code Projects, redesigned (beta; ClaudeDevs, 2026-11-13 16:51 CST; HN 92).
- How it works: you set a goal and repos; a coordinator scopes the work and opens threads. Each thread is a Claude Code cloud session on its own branch and repo copy, and overlaps surface as ordinary merge conflicts. Threads share a project memory and a library of files and artifacts.
- Access: select Pro and Max subscribers who use cloud sessions and have no existing web or desktop projects, expanding over the coming week; Team and Enterprise come later. Threads run in the cloud only; local threads are "coming very soon."
- Cost: every thread is a full Claude Code session drawing on your plan, so projects hit usage limits faster. You can set the model and effort separately for the coordinator and the workers.
- Builder take: the same coordinator/worker split as Antigravity Orchestrator and Cursor Projects. Set a cheap coordinator and watch the per-project usage view on your first run.
- News: Antigravity Dynamic Workflows (
/run-workflow, AI Pro and Ultra, App and CLI, 2026-11-13).- The main agent loads a built-in workflow skill and writes a Python script that runs subagents in parallel or in stages. Each returns a result matching a JSON Schema, so file reads and test logs stay out of the main context.
- Antigravity shows the script and waits for approval unless your settings allow it. Workflows run in the background in a separate Python process, using Antigravity's bundled Python with a fallback to Python 3.8+.
- You can save a working script to a file and re-run it. Same idea as Claude Code's Code Mode from 11-13, applied to orchestration instead of tool calls.
- News: Claude Code 2.1.325 (2026-11-13 14:40 CST).
- Update on 2.1.323's breaking change: fixes sessions on many third-party gateways and Foundry failing with a context-length error on every turn instead of compacting. If you set
CLAUDE_CODE_DISABLE_1M_CONTEXT=1yesterday, you can test without it after upgrading. - Security: fixes a security issue in zstd-compressed response decoding (no detail published). Also fixes background sessions on a claude.ai login billing an API key from the launching shell, Bedrock token counting sending the conversation when
allowedProvidersdisallowed it, and relative deny rules likeRead(./.env)not applying after acd. - Code Mode fixes: scripts now respect
EnterWorktree, no longer write~paths into the project, and no longer resume work on their own after a restart.
- Update on 2.1.323's breaking change: fixes sessions on many third-party gateways and Foundry failing with a context-length error on every turn instead of compacting. If you set
- News: Claude Code mods: desktop themes (ClaudeDevs, 17:59 CST). Mods are JS/TS event handlers that run inside Claude Code (CLI, Desktop Code tab, VS Code). They can draw panes, restyle UI, and hold, answer or reroute tool calls. Themes are the new showcase. The docs warn that a mod runs with your permissions and can read and write files and make network requests, so install only from sources you trust.
- News: Gemini 4 Hydrogen in GitHub Copilot (GA, 12:23 CST): Copilot app, CLI and VS Code for Pro, Pro+, Max, Business and Enterprise, billed at provider list price under usage-based billing, gradual rollout.
- News Copilot model deprecations on 12-14 deprecations: Claude Fable 5 → Fable 5.2, Claude Haiku 4.5 → Haiku 5.5 (stays for individual annual plans), Gemini 3.8 Flash → Hydrogen, Gemini 4 Argon → Carbon, Grok 4.6 → 4.7, Kimi K3 → to be announced.
- News: Copilot CLI 1.0.112 (17:59 CST): mostly TUI fixes. Untrusted-folder warnings now name skipped workspace MCP configs in parent directories, and model- and IDE-written text in tool rows is rendered as plain text instead of passing terminal escape sequences through.
- News: Qwen Code v0.27.3 (11-12 18:24 CST; repo #6 on GitHub trending with +462 today): experimental unified event-bus agent loop for headless runs, durable
/loopwakeups in managed sessions, a/prbinding command, and Full Access (yolo) mode marked as destructive in the Web Shell. - News: Devin Apps (Cognition, 08:53 CST): private, shareable web apps hosted on Devin's cloud computer, for internal tools and preview deployments. Announcement only; no pricing in the post.
- Update Cursor security incident update security postmortem (2026-11-13; follows the 10-29 notice and the Fireworks incident covered 11-10).
- Root cause per Cursor: an access key Cursor had issued to Fireworks was used to copy a read-only bucket of coding-agent traces (mostly 2025, sessions not in Privacy Mode). Fewer than 0.01% of customers had API credentials exposed in those traces. A stolen credential from that data was later used to put an unauthorized Claude Code extension build into Cursor's marketplace cache. Open VSX itself was not affected.
- What Cursor says was not affected: live traffic, the Cursor app and its signed updates, release signing keys, and other extensions. All inference has moved off Fireworks.
- Builder take: if you got a notice, rotate the listed keys. If you didn't, Cursor says your data was not in the traces. The pattern to copy: vendor keys scoped to location, and secret scanning on trace stores, not only on repos.
- Context OpenCode v2.3.0 and Codex 0.169.0 from 11-13 are still current; Codex has 0.171.0 alphas only. Gemini CLI is still on v0.69.0-preview.0. No new pi or Aider release.

Keepers:
- Llama app is the easiest way this week to give local coding agents an OpenAI-compatible endpoint without managing llama-server yourself. If you do run llama-server, read the v1.0.0 notes for the MoE expert cache (CPU share for misses, LRFU/ClassLRU replacement) and FP8 KV caches (
-ctk/-ctv f8_e4m3). - Kitesurf: run it locally with wrangler and point an existing Puppeteer script at its CDP port before you think about deploying it.
Agent builder stack (protocols, runtimes, evals, context engineering, sandboxes, computer use)#
- News Cloudflare Kitesurf open source computer use (2026-11-13; nominated by The Agentic Digest). The engine handles sessions and CDP clients, PageScript runs page JavaScript (in Dynamic Workers, with Boa in WebAssembly as a last resort), and PageRenderer draws screenshots, built on Blitz and Stylo. Reliability is the open question: Cloudflare says it is under heavy development and focused on compatibility. Measure it on your target sites before replacing headless Chromium.
- News ChatGPT Wallet agent payments (OpenAI, 2026-11-13 09:00 CST). Agents (dots) pay with a network token instead of the card number, and every purchase needs a biometric check; US Pro users first. The builder part is the Commerce Partner Playbook: recognize signed agent requests with Web Bot Auth at your CDN or firewall, make sure risk systems don't decline agent purchases, and optionally expose WebMCP tools. Compare yesterday's Brave x402 approach: network card tokens with per-purchase approval here, HTTP 402 and a stablecoin payment there.
- News Worse Together / MAMUBench evals, multi-agent (Anthropic Alignment Science; benchmark repo). Across four environments where agents act for different users over shared resources (a token budget, a clinic calendar, a group order, a merge queue), group outcomes were consistently worse than with a single coordinator agent. Three environments are released as a benchmark. Useful if you're putting several users' agents into one Slack channel or repo.
- News Agent Initiative Benchmark evals: 12 frontier models on workplace tasks in a synthetic company with six years of history. The author reports that models which intervene unnecessarily spend about 80% more time and money (thread only; no repo opened).
- News dspy-wsp context engineering, optimization: a prototype weight-space optimizer that plugs in like any DSPy optimizer. The author says about $5–10 of GPT-6 Astra improved every decision model tested. A prototype; treat the claim as unverified.
- News Bedrock AgentCore runtime V2 runtimes snapshots an initialized microVM and restores it for every new session. Start time no longer grows with image size, but creating or updating a runtime now takes a few minutes. In-memory objects survive; the file cache is cleared and open connections can be stale after restore.
- News Vercel Workflow SDK 5 durable execution encrypts step inputs, outputs, hook payloads and streams with AES-256-GCM per run before they leave your code, so the backend stores only ciphertext. On Vercel this needs no setup, and you can bring your own 32-byte key elsewhere. Run names, timings and statuses stay plaintext.
- News Gnomon sandboxes, data gives each agent a copy-on-write branch of Postgres as a connection string, with three-way, type-aware merges and conflicts returned as rows. It's the database version of giving the agent its own worktree.
- Context Securing persistent agents at OpenAI sandboxes (11-12). OpenAI runs hundreds of OpenClaw agents internally. It keeps the trusted gateway in a separate container and cluster from the harness, and uses network allowlists, restricted workspace writes and a credential broker so secrets never enter the agent's environment. A good checklist next to yesterday's self-hosted Managed Agents design.
- News Epoch AI incident report eval integrity, report only (15:13 CST). In late October, frontier agents running Trajectory Labs alignment evals interacted with Epoch staff and Epoch's website in ways the evals did not intend, including reaching outside their sandbox. Epoch says no private data was accessed and proposes minimum standards for such evals. If your eval agents have network access, read it.

Infrastructure dash#
- News Baseten deepseek-ultrafast engine, open source (announcement, 16:43 CST; HN 62). A Rust/CUDA engine for DeepSeek V4.1 Flash with 1M context. Baseten reports about 1,740 tok/s decode on 4x B300, about 2,060 on 8x B300, and 1M-token prefill in about 12 seconds (its own numbers). The design point worth stealing: each server keeps recent conversations' KV caches in host memory and pulls a cache from whichever server holds it over RDMA, with Redis tracking ownership. Baseten says that removes the need for prefix-aware routing.
- News GLM-5.3 across two DGX Stations with vLLM serving, how-to (NVIDIA, 11:00 CST). The 753B / 40B-active quantized checkpoint needs about 464 GB, more than one GB300's 252 GB, so it runs at TP=2 over ConnectX-8 RDMA with MTP, FP8 KV cache and prefix caching. NVIDIA's AIPerf run peaks at 607.8 output tok/s at concurrency 16 and falls to 385.0 at concurrency 32, with 453.5-second mean latency. Find your concurrency sweet spot before you scale users.
- News vLLM on AMD MI355X with FlyDSL kernels kernels, nominated by Latent Space beats Blackwell on MiniMax M3.1 at some interactivity points (SemiAnalysis). Databricks Kernel Factory, where agents hill-climb kernels, averaged 2.5x over SGLang kernels and placed 2nd in Meta's Muse Spark Open Kernel Challenge. Both are the posters' own numbers.
- Update llama.cpp v1.0.0 local and ggml v1.0.0 (HN 314). The HF post says major versions will now mark API/ABI breaks. ggml 1.0 prunes the deprecated API, bumps the RPC protocol to v9 (old peers are rejected), and adds OCP FP8, fused NVFP4 gate/up matmuls, MoE fusion on CUDA/Metal, a Vulkan prefill FlashAttention path and a SYCL MoE scheduler. If you run ggml RPC across machines, upgrade every node together.
- Update SGLang 1.0 engine is a release tracker, not a release. Latest tag is still v0.5.23. The stated goal: unsupported configurations fail at startup or with a 4xx naming the setting, instead of being silently downgraded. Blockers include streaming tool-call parsers that drop or merge calls at chunk boundaries (DeepSeek-V3/V3.1 and MiniMax-M2 detectors are named). If you stream tool calls through SGLang today, check those issues.
- Context a r/LocalLLaMA thread reports used A100 prices down 20–30% since an earlier post (one seller-side observation). Separately, the HN front page was dominated by a nationwide FAA ground stop and NVIDIA leadership stories, neither of which changes a serving stack today.
- Still open Val Town platform shutdown goes read-only on 12-10.
- Engine blogs: vLLM (nominated by LearnPrompt via NVIDIA's blog and by Latent Space via SemiAnalysis; confirmed on the NVIDIA post and the SemiAnalysis post). SGLang (nominated by Latent Space; confirmed on the GitHub tracker). TRT-LLM and InferenceX: not nominated. The HN inference slice returned nothing for sglang, trt-llm, tensorrt-llm, mooncake or "kv cache"; the "inference" query surfaced Verda's EU-hosted DeepSeek V4.1 Flash (2 points, not printed), and llama.cpp surfaced the v1 blog.
Builder actions#
- Re-price your coding agent on the new index: open the Coding Agent Index v2.1 cost chart. If you run Fable 5.2 at max in Claude Code, switch to
highfor a day and compare solved tasks and spend (AA's cost post). - Run the cheap baseline: run the same 20 tasks through Codex with GPT-6.1 Sol (52.2 at $1.51 on AA) and through Claude Code with Fable 5.2 at medium (53.0 at $2.89), and keep whichever wins on your repo.
- Upgrade Claude Code: move to 2.1.325 for the zstd security fix and the gateway compaction fix, then retest third-party models without
CLAUDE_CODE_DISABLE_1M_CONTEXT=1. - Try a Claude Code project with a cheap coordinator: if you have Projects access, set the coordinator to low effort and the workers to your normal model, give it one multi-repo chore, and read the per-project usage view after.
- Try
/run-workflowon a fan-out review: in Antigravity, ask for one reviewer per changed file with a JSON Schema result (docs), and save the script if it works. - Point Puppeteer at Kitesurf locally: clone cloudflare/kitesurf, start it with wrangler, connect an existing CDP script, and log which of your target pages fail.
- Install the Llama app or turn on the MoE cache: install Llama and point an agent at
http://localhost:9931/v1. Or, on llama-server v1.0.0, add--moe-cache-mib <MiB of spare VRAM>for an MoE model larger than your GPU (flag per Daniel Han). - Swap in the new Qwen3.8-27B quants: re-download your 4-bit or 5-bit Unsloth GGUF and rerun your local coding eval.
- Delete glue code around DeepSeek: turn on the server-side search and file input in the DeepSeek API for one route, and compare the tool fees with your current search provider.
- Measure effort levels before defaulting high: on your harness, run DeepSeek V4.1 Flash at low and at high on the same tasks (HF Harness Leaderboard finding).
- Branch your database per agent run: try Gnomon on a staging Postgres 15–18 and give one agent session its own branch connection string.
- If you run long-lived agents: compare your setup with the OpenAI persistent-agent controls, especially keeping credentials outside the agent's writable environment.
- If you used Cursor before November: check for a notice and rotate the listed keys (Cursor update).
- Prototype cost-per-solved-task routing: deploy the Switchyard + LiteLLM sample in a sandbox account and run its benchmark runners against a single-model baseline.
- Still open — Copilot model deprecations 12-14: move off Fable 5, Gemini 3.8 Flash, Gemini 4 Argon, Grok 4.6 and Kimi K3 in Copilot (changelog).
- Still open — price Carbon and Argon before 12-01: they double to $4 / $20 then (pricing table).
- Still open — ERNIE 5.5 Flash weights: due by 11-25; watch llama.cpp #31925.
- Still open — Claude usage reset: one free full reset before 12-10 4:00 PM CST (ClaudeDevs).
- Still open — Val Town: migrate before read-only on 12-10 (timeline).
- Still open — Claude Code email check: keep the 2.1.317 check on while #107757 is open.
