This post summarizes the accelerating "release season" in the AI community. The author notes that GPT-5.6 delivered the breakthrough they were hoping for, though they quickly hit rate limits. They also mention the return of Fable 5, Meta's increasingly competitive Spark 1.1, the subsequent release of Grok 4.5, and SpaceX hinting that a true flagship model is on the way.

On the open-source front, the author describes GLM-5.2 as an "aha / wow" moment for many, proving that open-source models are now viable alternatives to Western closed-source models in key areas. They also mention that the founder of Zhipu hinted at a next-gen model arriving soon, having previously mentioned in a chat that a Mythos-level open-source model would drop this year. Additionally, rumors suggest Kimi K3 might launch tomorrow with a 1-million-token context, and ChatGPT 6 could arrive in a matter of weeks featuring a brand-new pretraining pipeline.
