GPT-6 Astra lands as OpenAI's Fable rival, priced to match
OpenAI is rolling out GPT-6 Astra to a limited set of orgs today, with broader ChatGPT and API access in the coming days. It's the company's direct answer to Claude Fable, priced identically at $10/M input and $50/M output. Early numbers are striking: 99.9% on ARC-AGI 3 (via a custom harness), 100% on ExploitBench, and near-perfect long-context recall out to 1M tokens. Not all wins, though: it still trails Fable on the Intelligence Index.
