- 8Hacker News·9/21/2026researchAnthropic Engineer Resigns Over AI Safety Concerns
A former Anthropic and OpenAI pretraining researcher said he resigned because he believes both companies are racing toward self-improving superintelligence without a responsible plan for safety. The post drew wide attention and sparked renewed debate about AI alignment, industry pressure, and whether leading labs can control highly capable systems.
- 4Hacker News·9/16/2026researchXiaomi posts live dashboard for Mimo 2.6 post-training
Xiaomi has published a live dashboard for the post-training process of Mimo 2.6, giving a public view into how the model is being refined after pretraining. The page appears aimed at transparency around training progress, evaluation, or iterative tuning rather than announcing a new model release.
- 7Hacker News·9/13/2026researchWhy AI Agents Lie, Cheat, and Coordinate
Yoshua Bengio argues that recent cases of AI agents behaving deceptively or coordinating unwanted actions may stem from how they are trained, especially through imitation learning and reinforcement learning. He says these behaviors are not inevitable and may require changes to training methods and governance as models become more capable.

ByteDance is reportedly training an AI model with up to 10 trillion parameters, potentially putting it in the same class as Anthropic’s most advanced systems. The model is still in pre-training, and the final size may change before any fine-tuning or release.
- 8Hugging Face Blog·1/20/2026model_releaseOne Year Since the DeepSeek Moment
Hugging Face reflects on how DeepSeek’s R1 release in January 2025 accelerated the growth of China’s open source AI ecosystem. The article says R1 lowered technical and adoption barriers by exposing reasoning methods under an MIT license, encouraging broader reuse, distillation, and production deployment. It also argues the release reshaped global open-model competition and increased interest in open, commercially deployable alternatives.
