OpenAI GPT-6 Astra launch and agentic-workflow push

OpenAI is reportedly rolling out GPT-6 Astra with roughly 1.05M-token context, 128K output, stronger coding, computer use, delegation, cybersecurity, and persistent coding workflows across ChatGPT, Codex, API, AWS, and selected customers. New comparisons with Fable 5.1 emphasize that pass@1 and promotional benchmark claims are insufficient for judging real agent performance; independent validation remains limited.
