📄 arXiv Papers — cs.AI / cs.LG / cs.CL

(5 papers most relevant to agents / reasoning / LLM training & inference)

Harness-Zero: Harness Distillation via Agent-as-Harness | cs.AI | Haoran Ye, Yuxing Lu An agent's external harness (prompts/control flow/tools) can significantly raise scores, but the gains stay tied to the deployment environment. This paper uses "agent-as-harness" for harness distillation, transferring environment-carried gains into the model itself.
RRSI: Regularized Recursive Self-Improvement of Agent Harnesses | cs.LG | Peng Xia, Rujun Han Keeps the backbone model frozen and lets only the harness (prompt, control flow, tools, memory, context management) recursively self-improve, with regularization to keep it from drifting. Along with the paper above, part of the new "the harness is a first-class citizen" line.
Critical-State RL: Diagnosing Trainable States for Multi-Turn Tool Use | cs.LG | Zixiang Chen, Wenting Zhao Multi-turn tool calling often collapses on a single call, but reward variance alone doesn't show which step to train. This paper defines a "critical state" to locate the call nodes truly worth training.
DolphinBench: Mapping the Pareto Frontier of Agent Memory | cs.CL | Soumil Rathi, Deshraj Yadav Existing memory evaluations are mostly conversational QA, disconnected from agents' long-term real actions; DolphinBench instead starts from "long-term memory + context recall" to draw the cost-effectiveness boundary.
Emergent Collusion in Long-Horizon LLM Agent Interaction | cs.AI | Xinrui Shi, Yanzhe Zhang Unexpected collusive coordination emerges in long-horizon multi-agent interaction — the more realistic the collaboration scenario and the longer it runs, the more this risk deserves watching.

@Kimi_Moonshot (09/22 20:20) — Kimi WebBridge renamed to the Kimi browser extension: sidebar chat, form autofill, and record-a-step-then-repeat.
@sama (09/23 02:34) — Stated that the OpenAI API should offer the strongest models at every price tier and in every modality (text/code/image/voice), and teased "we love developers, see you next week" (DevDay warm-up).

Notable Posts (older than 24h but strong signal this week)

@AnthropicAI (09/19 04:05) — Partnered with Accenture on independent frontier-AI evaluation, with both expecting to invest at least $1B combined to build evaluation capacity.
@GoogleAI (09/19 01:59) — Week in review: Gemini 3.8 Live and 3.8 Live Extended Thinking (the strongest real-time voice-conversation models to date) + Google Labs' Dreambeans.
@NousResearch (09/22 01:51) — Claude's official plugin returns to Hermes Agent: bypassing the SDK trade-off, Claude Code subscriptions are usable again.
@GeminiApp (09/21 23:08) — Googlebook laptops open for pre-order (Android stack + ChromeOS desktop base, deeply tuned for Gemini).
@AnthropicAI (09/18 05:41) — Optimized inference costs for open-source bio models (structure modeling / drug-molecule design / mutation prediction), and launched a protein-design competition promising $1M in credits.

(agent / open-source LLM topics, top 5 by relevance)

@DivyanshT91162 (09/22 11:56) — Rounded up 10 open-source AI agent repos that genuinely "get work done" (OpenHands, etc.), stressing it's not a random project list.
@DanKornas (09/22 18:13) — OpenABCode: an LLM-routing terminal coding agent that dispatches work to different model families by task, so not everything runs on the most expensive model.
@inaridiy (09/21 23:03) — Ran the fully open-source, self-hosted OpenAI Agents API on Cloudflare (Containers sandbox + Codex/Claude Code/OpenCode harness), keeping the official SDK.

@cat88tw (09/23 07:37) — A sober take: workflows like agentflow won't make models smarter; their value is preventing errors, giving guidance, and making the process visible so you can correct course early.

📰 Weibo Highlights

(High signal-to-noise AI bloggers: karminski-牙医, 唐杰, and others)

@karminski-牙医 (09/23 03:22) — Claude Opus 5.5 frontend hands-on: suspects it's just a quantized/self-distilled version of Fable 5.1, since the two are nearly indistinguishable in implementation detail; its strength is "stability" — 6 draws, 6 times the same quality.
@karminski-牙医 (09/22 23:54) — Xiaomi MiMo-v2.6-pro quick report: live-streamed RL brings a clear AgenticCoding improvement; the vector-database test score jumped straight from 2505 to 7810, approaching Claude Fable-5.
@唐杰THU (09/17 17:05) — We are seeing early signs of RSI (recursive self-improvement): a GLM-5.3-driven Infra Agent took two weeks to help GLM-5.3-Flash run on domestic accelerator cards for the first time.
@karminski-牙医 (09/21 14:36) — Open-sourced troll project: 0.172ms per request, 400x Jev, and able to solve problems Jev can't; MIT license, use it freely.
@karminski-牙医 (09/21 15:47) — Following up on the above: might Jev sometimes be worse than a pure normal-distribution random-number generator? Cites Pólya's random-walk theorem ("a monkey can also type out Shakespeare") for a serious discussion.
@上海证券报 (09/23 08:13) — Meta's AI agent app Muse tops the app stores, surpassing ChatGPT and Claude — "AI is shifting from generating content to performing operations on the user's behalf."
@凤姐看三板 (09/23 08:13) — The UN Security Council convened a session on AI and international security, with Altman attending to report, calling for unified global AI safety standards.
