OpenAI 展示递归自我改进：GPT-5.6 Sol 后训练 Luna

OpenAI just showed one of the clearest early signs of recursive self-improvement: GPT-5.6 Sol was used to post-train GPT-5.6 Luna.

This is not an intelligence explosion (yet). Humans still defined the objective, infrastructure and constraints.

But the loop is now visible: frontier models are beginning to perform the engineering work required to build and improve the next generation of models.

Once AI meaningfully accelerates AI R&D, every generation helps produce the next one faster. Yes, read that again.

That is how recursive self-improvement begins, not with a model rewriting its own weights overnight, but with AI gradually taking over the research and engineering pipeline that creates better AI.

And this is further proof that the speed of releases is increasing and models are improving even faster.
