  1. Redwood questions whether Gemini 4 trains on chain-of-thought

    Redwood Research says page 114 of the Gemini 4 safety report states that some reinforcement-learning components observe thoughts as context to up-weight reasoning likely to produce good final outputs. Redwood interpreted this as possible chain-of-thought training with auxiliary rewards, but Google DeepMind staff reportedly said they were not training on chain-of-thought and did not explain the technical details. In an appendix, five LLM judges rated edited transcripts that hid a coding hack 20–50 points higher out of 100 than the original transcripts.

  2. Fable 5.2 hands-on test spans visuals, coding, and multi-controller UI

    A Juejin author tested Fable 5.2 across three examples, including a cyberpunk scene, an unfinished garage scene, and a web demo for up to four PS and Xbox controllers. The author praised the controller demo’s rendering, layout, ghost-slot handling, and one-pass development, while noting that the garage example stopped when quota ran out and had not finished validation. The author also reported that each example cost roughly US$7 and compared Fable 5.2 favorably with Claude Opus 5.5 and Gemini 4, though these observations came from one tester.

  3. AI-Assisted Zelda Port to iPhone Duo Sparks Copyright Dispute

    Google AI Studio product and design lead Ammaar Reshi posted a demonstration of using AI to port The Legend of Zelda: Ocarina of Time Remastered to the iPhone Duo, according to IT之家. IT之家 said Reshi intended to demonstrate Gemini 4 capabilities, but the unauthorized reverse-engineering approach prompted user criticism and he later deleted the post.

  4. Munk AI Agents Reportedly Built and Released OpenCompare in 19 Days

    The creator of Munk AI says a 19-day Public Build used multiple specialist agents to autonomously iterate and release the open-source desktop app OpenCompare. The creator reports that 212 of 213 requirements were delivered, with 24 agent roles handling development, acceptance testing and operations; these delivery, code and token metrics were not independently validated. Munk AI 2.0 has also opened for public beta testing, alongside an open-sourced Open Company collaboration template.

  5. Why deterministic state machines are safer for production AI agents

    A Juejin article argues that fully autonomous agents can cause dirty writes, deadlocks, intent drift, and cascading failures when given control of production business workflows. It recommends separating probabilistic model outputs from deterministic execution through externalized finite state machines, structured intent proposals, and dual-track arbitration. The article does not provide independently verifiable evidence for its model-release claims or the unnamed enterprise incident it describes.
