CometAPI's explainer, updated September 4, 2026, reports OpenAI released GPT-6 Astra on September 3, 2026, as a flagship model oriented around complex reasoning, computer use, coding, research, scientific work, and professional artifact creation. The API model is listed with a 1.05M-token context window, 128K maximum o The article frames the practical change as concentrated in agentic execution, computer use, long-context retrieval, coding workflows, science, and cybersecurity rather than as a uniform jump on every general-intelligence benchmark, and includes a Python and Node.js code snippet showing the request pattern for calling G

BenchLM's model record, dated to the GPT-6 Astra launch window, lists the model as released September 3, 2026, with a 1.05M-token context window, text/image input support, and a reasoning-effort capability spanning low through max. API pricing is recorded at $10 per million input tokens and $50 per million output token The aggregator assigns GPT-6 Astra a composite capability score of 81.1 out of 100, ranking it 2 of 232 tracked models, and shows it at the 100th percentile in Reasoning (ranked 1 of 22), with Agentic at the 97th percentile (5/151), Coding at the 98th percentile (4/183), and Knowledge at the 98th percentile (4/181).

OpenAI released GPT-6 Astra on September 3, 2026, framing it as "the world's most intelligent and aligned model" and the product of its largest training run to date, executed on more than 100,000 GPUs at the Stargate site in Texas. It is also the first release where earlier OpenAI models supervised the training of the Astra also becomes the first model to hit the "Critical" cybersecurity threshold under OpenAI's Preparedness Framework, which is why advanced cyber capabilities are being gated behind the Daybreak application-based program and the rollout is intentionally phased. Vellum notes that not every benchmark favors OpenAI: Met

OpenAI announced the phased rollout of GPT-6 Astra on September 3, 2026, with CEO Sam Altman calling it a "new capability level" that has changed his workflows and predicting "a boom of entrepreneurship, of creativity, of economic growth, of scientific discovery." Distribution channels for Astra include ChatGPT Plus, P Companies participating in OpenAI's application-based Daybreak cybersecurity program are first in line for access, because Astra is OpenAI's first model to reach the "Critical" internal cybersecurity threshold disclosed earlier in the week, with those advanced cyber capabilities explicitly limited. CNBC notes that two

Coursiv's guide, dated September 1, 2026 but referencing the September 3, 2026 official release, states OpenAI launched GPT-6 Astra publicly on that date with a 1.05M-token context window and up to 128,000 output tokens. It reports API pricing of $10 per million input tokens and $50 per million output tokens, and adds On rollout, the article says OpenAI began with access for a limited group of organizations and is expanding to ChatGPT Plus, Pro, Business, and Enterprise users alongside the OpenAI API, and notes no broad GPT-6 Astra access for the ChatGPT Free tier had been announced at time of writing.
