OpenAI answers Opus with GPT-5.3-Codex, first model that helped build itself
One hour after Opus 4.6, OpenAI released GPT-5.3-Codex, billed as the first model instrumental in developing itself — the Codex team used early versions to debug its own training and manage its own deployment. It scores 73% on Terminal Bench 2.0, a 10-point gap over Opus 4.6, while running queries 25% faster and more token-efficiently than its predecessor, with improved mid-task steerability.

Grok 4.1 Fast: 2M context and Agent Tools API at 10x lower cost
Launched as breaking news during the show, Grok 4.1 Fast pairs a 2 million token context window with a new Agent Tools API offering native X search, Reddit search, web browsing, and code execution. Benchmarks are striking: 93-100% on tau2-Bench Telecom and 72% on Berkeley Function Calling v4 (top of the leaderboard) at $0.20/$0.50 per million tokens — roughly 10x cheaper than competitors, and free for the first two weeks on the xAI API and OpenRouter.
OpenAI ships gpt-realtime and takes the Realtime API to GA
OpenAI shipped the gpt-realtime speech-to-speech model and moved the Realtime API to general availability.
