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

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

Quantifying Overclaiming Propensity in Frontier LLM Agents | cs.SE | Nolan Smyth, Yorguin-Jose Mantilla-Ramos Quantifies frontier coding agents' tendency to "overclaim": users often only see the agent's final reply, which may overstate the work actually done.
An Empirical Study of Harness Design for Coding Agents | cs.AI | Run-Ze Fan, Zihao Zhang Empirically studies how the coding harness turns model capability into long-horizon software-engineering performance, pointing out the shortcomings of evaluating the harness as a black box.
RetireOPD: Self-Retiring On-Policy Distillation for Agentic Reinforcement Learning | cs.CL | Yan Yu, Zhengxi Lu Multi-turn agent RL has only a single trajectory-level scalar reward; this uses a "self-retiring" on-policy distillation to supply dense token-level supervision.
Score Centering Stabilizes Off-policy Reinforcement Learning | cs.LG | Martin Marek, Max Ryabinin Targeting LLM off-policy RL instability caused by training/inference engine differences (TIM), it proposes score centering for stabilization.
Coding Agents with an Obstacle-Aware Harness for Safe Robot Manipulation | cs.RO | Bingxin Xu, Yuzhang Shang Moves the "language model writes the robot controller" coding-agent paradigm to robotic-arm manipulation, using an obstacle-aware harness to ensure safety.

🔴 Key Signals (within 24h)

@dotey (09/20 06:02) — Reverse-engineered a thermal label printer's firmware with Fable-5.1: the vendor uses RFID consumable locks to slow speed and degrade quality; the model derived the darkness formula darkness=renderer_input×coefficient and located the memory address, cracking it after a few reflashes.
@Teknium (09/20 04:00) — Publicly criticized Jev's compaction strategy: at 500K context it deletes 250K of tool calls, only able to compress back to 250K instead of an abstractive 50K, so usable space keeps shrinking with each round.
@dotey (09/20 03:59) — Shared the AI short film 《归墟 1-9》: about $20k, a one-person work — "live actors are under huge pressure."
@dotey (09/19 23:15) — Thinking from Asimov's Foundation: if AI systems all failed someday, the IT industry might regress to Y2K or earlier.
@Teknium (09/19 16:31) — Released his first Hermes plugin.
@openclaw (09/19 11:28) — OpenClaw 2026.9.5 released: atomic updates, plugin hot reload, session sharing, GPT Live extension, shared browser pages, session archiving, expert agent config; this release: 502 contributors, 4,179 PRs.
@NousResearch (09/19 08:26) — Welcomed Mark to the Hermes Core team.

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

@OpenAI (09/18 04:15) — Launched Astra for Law: frontier intelligence for legal practice based on GPT-6 Astra, with 26 partner plugins + 47 community plugins (Thomson Reuters, Harvey, Legora, iManage, etc.), initially available via Trusted Access in ChatGPT and Codex.
@AnthropicAI (09/19 04:05) — Partnered with Accenture on independent frontier-AI evaluation, with both planning to invest at least $1B each over five years to build evaluation capacity.
@AnthropicAI (09/18 05:41) — Used Claude to optimize inference for 30+ open-source bio models, up to 4x faster; and co-hosted a protein-design competition with Adaptyv Bio ($1M in Claude credits).
@AnthropicAI (09/18 04:32) — Published three internal metrics tracking AI progress: how much AI R&D AI takes on, how supervised agents are, and how compute is allocated.
@GoogleAI (09/19 01:59) — Week in review: Gemini 3.8 Live / 3.8 Live Extended Thinking (strongest real-time conversational audio models), Dreambeans to GA, and CC expanding from a personal-productivity tool to a family-shared agent.

@dotey (09/20 06:02) — The full approach to cracking the RFID consumable-lock label printer firmware with Fable-5.1.
@Teknium (09/20 04:20) — Clarified that the criticism above targeted Tamara's compaction strategy/repo, not Jev itself; Jev still has many valid use cases.
@Teknium (09/20 04:00) — A breakdown of Jev compaction's exact mechanism (500K → deletes 250K of tool calls → can only compress back to 250K, degrading round by round).
@dotey (09/20 03:59) — 《归墟 1-9》, an AI short film, ~$20k, done solo.
@Teknium (09/20 03:50) — Noted that in public evals this compaction degenerates into a procedural rule: delete all tool calls — free and reproducible.

📰 Weibo Highlights

(High signal-to-noise channels: karminski-牙医, 宝玉, and other AI bloggers)

@半仓龙 (09/20 08:15) — Mapped the AI hardware industry chain: compute chips, HBM memory, high-speed interconnect, PCB, power, liquid cooling, comparing overseas leaders with core domestic firms segment by segment.
@爱可可-爱生活 (09/20 08:04) — #AI资本开支压力显现#: tech giants' AI buildout is hitting cash-flow and debt headwinds, with several top companies unusually calling for slower model iteration — the industry is shifting from "an arms race at any cost" to "doing the math."
@karminski-牙医 (09/20 05:58) — Relayed the project that used Fable5.1 to crack a thermal label printer's firmware: the vendor uses RFID consumable locks to slow speed and degrade quality; the author derived the print-darkness formula and successfully reflashed it.
@karminski-牙医 (09/20 05:14) — Rebutted "use Jev for high-frequency trading, and if you lose, just trade the opposite": Jev is underfit to candlestick charts, so unless you could achieve 100% negative correlation, trading the opposite won't make money either.
@karminski-牙医 (09/18 17:11) — Guessed Zhipu's just-released GLM-5.3-FlashX is an accelerated version of GLM-5.3-Flash.
@karminski-牙医 (09/18 08:56) — Qwen3.8-Omni-Flash released: average score +25% over the previous generation, with agent-capability scores doubling; accompanied by two frameworks, Qwen-Live-Harness and Qwen-MM-Plugins.
@karminski-牙医 (09/18 06:45) — Introduced the Jev model: it abandons the traditional autoregressive architecture and can't output ordinary text, but it can output JSON-form decisions — worth close attention.

🎯 One-Line Summary of the Day

"The dominant thread of these 24 hours is 'the engineering and trustworthiness of agents': GitHub Trending is dominated by coding-agent skills and runtime environments (security-audit-skill, agent-skills, coder, claude-code plugins); arXiv concurrently posts two empirical studies on 'coding harness design' and 'agent overclaiming'; OpenClaw 2026.9.5 ships atomic updates and plugin hot reload in one go; and on the open-source side, landed value shifts from 'the model itself' to 'harness + toolchain' — Anthropic used Claude to speed up 30+ open-source bio models 4x, and Qwen released Omni-Flash with two companion frameworks."
