Meta has released Muse Glimmer, a small, open-source AI model capable of running agents on-device, which they claim outperforms similar-sized rivals like Gemma4 and Qwen3.6 on various tests. This move signifies Meta's return to its open-source roots, with plans to release Muse Spark 1.2 soon, positioning it as a strong competitor to China's open-source AI ecosystem. Concurrently, OpenAI has expanded its 'Daybreak' program to include GPT-5.6-Cyber, a specialized model for cybersecurity research that bypasses many standard safety guardrails to answer advanced attack requests from vetted defenders.
