- GPT-6 Astra launches to a limited set of organizations, with broad access to follow within days Launch
OpenAI introduced GPT-6 Astra, calling it its most intelligent and aligned model and reporting 98 percent on FrontierMath Tier 4 and 99.9 percent on ARC-AGI-3. It rolled out first to a limited set of organizations, with ChatGPT Plus, Pro, Business, Enterprise, the API and AWS to follow; API pricing was set at $10 and $50 per million tokens, and advanced cyber capabilities were gated behind OpenAI Daybreak.
on OpenAI Frontier Models: From GPT-4 to GPT-6 Astra - Jalapeño: OpenAI's first chip, designed with Broadcom in nine months, running GPT-5.3-Codex-Spark in the lab Launch
OpenAI and Broadcom unveiled Jalapeño, an inference accelerator OpenAI designed from scratch with Broadcom and Celestica handling implementation, boards, racks and networking. Engineering samples were running workloads at target frequency and power, and OpenAI said early tests showed performance per watt substantially better than the state of the art; the design-to-tape-out cycle of nine months was accelerated by OpenAI's own models.
