Rumor roundup: Google, OpenAI, Anthropic and xAI said to be racing toward RSI
A Chinese-language article from 新智元, republished by 36Kr and Cyzone, argues that Google, OpenAI, Anthropic and xAI are all racing toward recursive self-improvement (RSI), but attributes most specifics to unnamed people and rumor. It cites Anthropic's "When AI builds itself" account that Claude authored over 80% of its merged internal code as of May and that AI-led development work rose to roughly 26% by August, and says Anthropic is training a next-generation model it calls Fable 6. It repeats unverified claims of a Google launch cadence cut from 125 days to 44 days, an unreleased OpenAI model called Bel, RSI-Exam scores of 0.384 for Grok 4.7 versus 0.53 for Opus 5.5, and the withdrawal of a planned GPT-6.1 Astra release.
If accurate, AI writing and optimizing its own training would make monitoring and alignment the central governance question — though most specifics here remain unverified.
