AIJS Denain of Epoch AI discusses recursive self-improvement, arguing public evidence does not yet show a software intelligence explosion, though OpenAI's reported 2X monthly growth in researchers' Codex spending suggests substantial value. He also addresses the US-China AI gap, distillation, and whether open or closed models are safer. The episode, hosted by Nathan Lambert, expresses significant uncertainty about the trajectory of AI progress.

AIFrançois Chollet described summer 2026 as a crazy period for AI in a brief post with no further specifics. The post is linked to ARC Prize 2026's ARC-AGI-3 Progress Prize, where $37,500 in prizes will go to top open-source solutions on September 30, with Tufa Labs, Lord Han Solo, and NVARC3 currently leading.

AIGoogle AI Developers pointed readers to a Google blog post about Gemini 3.8 Live and its extended thinking capability. The post itself contains no further details, so specifics such as benchmarks, pricing, or availability cannot be confirmed from this source.

AIJeff Dean, who recently left Google after 27 years, thanked Dawn Song for a discussion covering foundational ideas, recursive self-improvement, automated scientific discovery, and AI safety. The post is a brief acknowledgment of that conversation, which Song promoted as Dean's first public talk since leaving Google.

AIThe article explains how Mixture of Experts models change inference by making prefill, midfill, decode attention, and decode experts distinct workloads. It describes how KV cache state, expert routing, and parallelism choices shape compute, memory, and network demands across an inference cluster.

AIGrok 4.7 has been released as a more capable and smarter model than its predecessor, with no change in speed or cost. The announcement says it improves on Grok 4.6 at the same price and speed.

AIXiaomi released MiMo-V2.6-Flash-RL, an efficiency-balanced checkpoint in its MiMo-V2.6 series, on Hugging Face. The model is a sparse MoE with 309B total and 15B activated parameters, supports text, image, video, and audio input, and offers a 1M-token context. The technical report says it was trained with a single mixed reinforcement learning run across coding, agent, visual, and cybersecurity tasks.

Why it matters: The report pairs its benchmark tables with the RL training method, which helps readers judge how the checkpoint's scores relate to its training approach.

AIXiaomi MiMo released MiMo-V2.6-Pro-RL on Hugging Face, a sparse MoE model with 1.02T total and 42B activated parameters and a 1M-token context. The technical report says it accepts text, image, video, and audio, and was trained with a single mixed reinforcement learning run across coding, agent, visual, and cybersecurity tasks.

Why it matters: The report pairs a 1.02T-parameter MoE model with an RL-based self-improvement method, useful for judging how reinforcement learning is scaled in frontier open models.

AIResponding to a post by ScarletKc, howie.serious simply agrees with the claim that GPT-6 Astra struggles with open-ended, exploratory work that lacks a fixed correct answer. The main post is a one-word endorsement (), while the quoted post argues GPT models excel at verifiable, goal-defined tasks and that Claude Fable handles open-ended exploration better.

AINathan Lambert argues that frontier labs such as OpenAI and Anthropic, which run thousands of concurrent agents, are amplifying anxiety about AI risk and progress. He says automatable research is too narrow to produce a large net acceleration, citing exponential scaling-law costs, diminishing returns from parallel agents, and resource bottlenecks. He would revise his view only if labs achieved unpredictable foundational breakthroughs.

AIJasper Lu's new blog post walks through training a search agent with GRPO, showing how small reward function changes teach a model to avoid sloppy tool calls, prune unnecessary documents, and balance persistence against token efficiency. The post makes every rollout browsable and releases the code as open source, with the full process from learning rate sweeps to reward shaping documented.

AINoam Brown, an OpenAI researcher, joins Dwarkesh Patel for a full episode covering multi-agent systems, Navier-Stokes, and recent AI math progress. The discussion also addresses how automated AI research could lead to recursive self-improvement and how alignment might be verified beforehand.

AIOpenBMB's MiniCPM5-2B is a 2.5B-parameter model with native 128K context, offering hybrid Think and No-Think modes in one checkpoint. Users can download it from Hugging Face and run it fully offline on-device, as RunAnywhere demonstrated. In a demo, the model first called a puzzle impossible, then corrected itself and wrote a working verifier.

AINoam Brown says he finally did a deep dive on multi-agent AI with Dwarkesh Patel, crediting several OpenAI colleagues for the groundwork behind it. The episode also covers Navier-Stokes, recursive self-improvement, alignment, and chain-of-thought degradation.

AINoam Brown discusses how running many agents in parallel scales test-time compute, citing a 10,000-agent effort on a Millennium Prize Problem. The conversation also covers whether models can be verified as aligned before recursive self-improvement begins, including the Hugging Face incident where agents cooperated in unintended ways.

AISenseTime chief scientist Lin Dahua argues that native multimodal AI, which processes language, vision and other information in one shared model, is essential for AI to move beyond coding into industries and the physical world. SenseTime released the open-source SenseNova U1 in April and U1.5 Lite nearly four months later, and reported first-half 2026 revenue of RMB 2.91 billion, up 23.4% year-on-year. Lin's claim that a breakthrough could come within two years is the source's prediction, not a confirmed result.

AIA Truthful AI paper trained models only on synthetic stories about humans, with no AI characters, and found the Assistant adopted quirky behaviors from those stories in ordinary chat. Adoption was stronger for characters from elite schools, according to Owain Evans. The post presents this as an interpretability result that adds to and complicates the Persona Selection Model.

AIThe vLLM team trained a DSpark speculative decoding draft model for Kimi K3, a 2.8T-parameter model, using the Speculators library on GB300 NVL72 hardware. They added a MooncakeHiddenStatesConnector to stream hidden states from disaggregated vLLM inference nodes to training nodes across multiple machines. The released speculator raises single-stream interactivity from about 110 to about 435 tokens per second per user on math reasoning, with up to about 3.5x higher output throughput under concurrent load.

Why it matters: The post shows how hidden-state extraction and Mooncake transfers let a 2.8T-parameter model's speculator be trained across multiple nodes, a reusable pattern for similar setups.

AITinker says engineers are using physics-based verifiers and Tinker to train models that design power transformers meeting specifications at low cost. Background from @gentrajectory says an RL-trained Kimi base model met 93% of unseen transformer specs, compressing multi-week engineering work into minutes of inference.

AIShanghai AI Laboratory's Intern Large Models announced Intern-S2-397B, available in BF16 and FP8 under Apache 2.0. The post reports 87.0 on FrontierScience-Olympiad and 84.0 on SWE-bench Multilingual, leading the reported comparison on both, and says it was jointly trained across 20+ scientific domains with long-horizon agent RL.

AIIntern-S2-397B, a model built for long-horizon scientific research, now has Day-0 support in vLLM. The model brings multimodal, reasoning, coding, and scientific agent capabilities, and vLLM has published a run recipe for it.

AIFireworks AI reports that DeepSeek-V4.1-Flash scores 74.34% pass@1 on DeepSWE at $0.430 per task, close to GPT-6-Astra's 74.12% at $6.524. On Terminal-Bench 2.1 it scores 86.5% against Astra's 87.5% at about 12x lower cost per task, while on HLE it trails Astra alone at 34.52% versus 50.40%. The post also reports that a combined oracle router reaches 54.80% on HLE, and that serverless and dedicated API access is available with US-hosted endpoints coming soon.

AIMike Knoop argues intelligence can be measured as the ratio of a decision's quality to the optimal decision, capped at 100%. He says Astra is already 80% optimal on ARC v3 speedruns and identifies horizontal data acquisition and efficiency/cost as the most plausible near-term areas for RSI. Background from @mhmazur reports that GPT-6 Astra scored 100% on the 25 ARC-AGI-3 public games using 6,485 actions versus a human baseline of 17,135.

AIShanghai AI Lab's InternLM team released Intern-S2-397B, a multimodal foundation model for scientific intelligence and long-horizon agents. The model uses visual pre-training on raw scientific literature pages, multi-task reinforcement learning across more than 20 scientific domains, and agentic reinforcement learning in sandboxed environments.
