OpenAI launches GPT-6 Astra, Anthropic releases Claude Fable 5.1 with new controls · 1 source tracked

By PulseAugur Editorial · [1 sources] ·

OpenAI has released GPT-6 Astra, its first full version-number jump in over a year, which the company claims is state-of-the-art in computer use, browser use, and software engineering, with its president suggesting it may represent AGI. Anthropic simultaneously launched Claude Fable 5.1, featuring significant improvements in benchmark performance and a substantial price cut for cached input. Both releases introduce new access and output controls: GPT-6 Astra is being rolled out in phases with advanced cyber capabilities initially restricted to vetted testers, while Claude Fable 5.1 includes an invisible watermark for provenance tracking, accessible to regulators and fact-checkers.

IMPACT New access controls and provenance tracking on frontier models signal a shift towards gated capabilities and verifiable AI outputs.
