Coverage update: X was unavailable for this edition.
OpenAI’s Astra is no longer just a rumor cycle: we now have rollout order, API pricing at $10 per million input and $50 per million output tokens, and an ARC-AGI-3 scorecard with a 35.2% instant standard-harness result to anchor operator expectations.
