TL;DR — On 2026-09-03 OpenAI shipped GPT-6 Astra, its most capable model for the hardest end-to-end work: reasoning, coding, computer use, research, and document creation. Official docs list text and image in, text out. Audio and video are not supported. If you need chapters from a long lecture, paste the link; you do not pick gpt-6-astra.
Paste a long-form video URL — BibiGPT turns it into chapters, a transcript, and follow-up Q&A. You never pick gpt-6-astra.
As of 2026-09-07, OpenAI released GPT-6 Astra on 2026-09-03 as its most capable end-to-end work model. Official docs list reasoning, coding, computer use, research, and documents — not audio or video. If you need a lecture turned into searchable notes, paste the link into BibiGPT instead of picking gpt-6-astra.
A flagship work model, not a video SKU. OpenAI positioned it for the hardest end-to-end jobs — then listed audio and video as unsupported on the model card.
The API changelog calls Astra OpenAI's most capable model for reasoning, coding, computer use, research, and document creation. ChatGPT release notes add templates for documents, spreadsheets, and presentations. That is office work, not a lecture pipeline.
reasoning.effort supports low, medium, high, xhigh, and max. The none level is rejected. Custom temperature, top_p, and logprobs are not supported. Treat it as a reasoning model, not a chat-completions drop-in.
The official model page lists text and image input, text output, a 1,050,000-token context window, and 128,000 max output tokens. Audio: not supported. Video: not supported. Do not write Astra into a transcription stack.
A stronger work model helps teams that already run OpenAI themselves. It does not replace a product that files chapters, a transcript, and follow-up Q&A for a human.
Paste a YouTube or lecture URL, get chapters and a transcript. The point of a video assistant is the artifact — not a model ID on an API dashboard.
Responses API adds async tool calling, mid-turn steering over WebSockets, and changing reasoning effort mid-conversation. Those are agent-loop controls. A 90-minute course still needs timestamps and export.
OpenAI said access is rolling out to a limited set of organizations and is not yet generally available. The Free API tier is unsupported. List price is $10 / $50 per 1M input/output tokens. Do not treat Astra as a public video model.
Headline shifts from OpenAI's 2026-09-03 API changelog.
GPT-6 Astra is billed as OpenAI's most capable model for the hardest end-to-end work. Model ID gpt-6-astra. This page is the SKU launch. Official docs do not name audio or video capability.
reasoning.effort supports low, medium, high, xhigh, and max. The none level is not supported. Custom temperature, top_p, and logprobs are not supported. Knowledge cutoff on the model page is 2026-04-30.
Tool calling requires the Responses API. New controls: async tool calling so the model keeps working while your app runs tools; mid-turn steering over WebSockets; change reasoning effort mid-conversation without dropping the cached prompt prefix.
Listed Standard price is $10 / $50 per 1M input/output tokens. Context window 1,050,000 tokens; max output 128,000. Inputs: text, image. Output: text. The model page marks audio and video as not supported.
OpenAI said access is rolling out to a limited set of organizations and is not yet generally available. Free-tier API is unsupported. Misalignment monitoring can raise safety alerts or pause a conversation for review on supported Responses requests.
Where the SKU matters — and where a summarizer is the actual product.
Use Astra on your own agent traces for coding, research, or document drafts. Then still dump the finished lecture into BibiGPT so humans get chapters instead of a raw token dump.
A 90-minute course video does not need a model ID. Paste the URL, export the transcript, ask follow-up questions. That is the BibiGPT path — a substitute workflow, not an Astra integration.
Astra is the 09-03 work-model SKU with no A/V input. GPT-5.6 is the prior family. Gemini 3.8 Flash is the same-week Google SKU that does take video. Keep each intent on its own URL.
The summarizer is the product. The other two URLs keep same-week model launches from colliding.
Launch claims come from OpenAI's own changelog and model card plus independent coverage.
On 2026-09-03 OpenAI released GPT-6 Astra as its most capable model for the hardest end-to-end work (reasoning, coding, computer use, research, document creation), with no none reasoning effort, no custom temperature/top_p/logprobs, Responses-only tool calling, async tools, mid-turn steering, and misalignment monitoring.
