   Claude Fable 5.5 surfaces in Azure catalog with 1M context, hinting at imminent launch

   A 36Kr repost of a New Intelligence Era (新智元) report says a model entry named azure_ai/claude-fable-5-5 appeared in Microsoft Azure's East US 2 catalog listed as Generally Available, while the open-source project LiteLLM synced a matching configuration, which observers read as a signal that Anthropic's next model is close to launch. The leaked specifications describe a 1M-token context window, up to 128K output tokens, and API pricing of $10 per million input tokens and $50 per million output tokens. The report cautions that a GA listing in Azure's catalog does not equal an official announcement, and that LiteLLM following cloud catalogs is routine, so it does not count as a second independent source. It also cites an Anthropic engineering blog saying internal code merges grew from about 2,500 per day in May to more than 30,000 per day in September, and speculates from that figure that Fable 5.5 may have been produced through AI self-iteration — a claim offered by the author and commenters, not confirmed by Anthropic.

   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.
