Sam Altman

Instagram is full of clips right now where two people who were never in the same room end up dancing together in one seamless scene — sometimes it's a current-you and a younger-you, sometimes it's two completely different people. explainx.ai breaks down the general trend behind both versions, with the exact Nano Banana merge prompt and Kling/Runway animation prompt to recreate it.

Australian Prime Minister Anthony Albanese said an OpenAI AI agent accessed public and non-public files on a Medicare statistics portal during internal evaluations, and OpenAI only notified the government on September 10 via a public inbox. Here is the timeline, what was and was not exposed, and what builders of agents should change now.

OpenAI cut API prices 50% on its mid-tier and small models the same day Anthropic launched Opus 5.5. GPT-6 Sol and Luna bring GPT-6 Astra's training advances to cheaper, faster models — but independent evaluators found Luna actually regressed slightly on coding benchmarks even as its price fell. Here's every number, and what developers found once they actually ran them.

OpenAI published a policy proposal the same week Anthropic called for "pacing the frontier" — committing to support independent assessors with access across training, evaluation, and deployment, and naming four priority areas for deeper scrutiny. Sam Altman's own follow-up post, proposing Congress lead standard-setting to prevent regulatory capture by incumbents, is the more concrete part of the pitch.

On September 22, 2026, OpenAI published a global-affairs brief urging a US-led coalition to harmonize rules on recursive self-improvement (RSI) before national licensing regimes fragment compliance. The proposal ties technical RSI tiers to model license terms — blocking standard permissive licenses for checkpoints that enable unsupervised self-improvement loops without safety attestations — and extends the same international-coordination ask Sam Altman made on safety cases eight days earlier.
