OpenAI released GPT-6 Astra on 3 September 2026. Google DeepMind has been running a research programme called Project Astra for far longer. The two have nothing to do with each other, and the collision is confusing enough that people are searching specifically to work out which one they just read about. Every claim below comes from the two companies' own live documentation, checked on 3 September 2026.
What is GPT-6 Astra?
GPT-6 Astra is OpenAI's newest frontier model and the top of its line-up. OpenAI's API changelog dates the release to 3 September 2026 and describes it as "our most capable model, built for the hardest end-to-end work" — reasoning, coding, computer use, research and document creation.
The concrete specifications, from OpenAI's model page:
- Model ID:
gpt-6-astra - Context window: 1,050,000 tokens, of which a maximum of 922,000 can be input, with 128,000 max output tokens
- Knowledge cutoff: 30 April 2026
- Inputs / outputs: text and image in, text out
- Reasoning effort:
low,medium,high,xhigh,max— thenonelevel available on other models is not supported - Tools: functions, web search, file search, computer use
- Constraints: no custom
temperature,top_porlogprobs; function calling works on both endpoints, while the hosted tools are documented for the Responses API
Pricing, from OpenAI's pricing page, is $10 per 1M input tokens and $50 per 1M output tokens. There is one threshold worth knowing: prompts with more than 272,000 input tokens are billed at 2x input and 1.5x output for the whole request, so a long-context call costs $20 in and $75 out. Cached input is $1, and the Batch tier halves the standard rate to $5 in and $25 out.
Availability is the detail most early write-ups get wrong. OpenAI's own wording is that GPT-6 Astra "is rolling out today for enterprises in our Trusted Access Program, with access through API and our Plus, Pro, Business and Enterprise plans coming in the coming days." On day one it is not simply switched on for every paying ChatGPT subscriber. It is reached through the OpenAI API and the paid ChatGPT tiers. It is also not a Bedrock model: OpenAI's Amazon Bedrock guide lists GPT-5.4, GPT-5.5 and GPT-5.6 but no Astra.

What is Google Project Astra, and has it actually shipped?
This is where most coverage is stale, because it repeats the original demo write-ups rather than checking the current page.
As of today, DeepMind's Project Astra page still describes it as "a research prototype exploring breakthrough capabilities for Google products — on the way to building a universal AI assistant." The page states plainly that Project Astra "is a research prototype, being used and refined by a limited number of trusted testers." Access is a waitlist form. There is no download, no price, no model ID and no API.
What the prototype does is genuinely different from what GPT-6 Astra does. DeepMind lists spatial processing, screen sharing and tool use as its current capabilities, and the page details proactive responses that start without waiting for a turn, on-screen agent highlighting to show what it is looking at, tool use across Search, Gmail, Calendar and Maps, and multimodal memory that carries across devices. It runs on Android phones and on DeepMind's prototype glasses.
The practically important point: the capabilities ship through Gemini Live, not through anything branded "Project Astra". DeepMind says "some of the latest features in Gemini Live were first explored using Project Astra," and that it is "working to bring Project Astra's capabilities to Gemini Live, new experiences in Search, as well as new form factors like glasses." Gemini Live is the shipped consumer feature inside the Gemini app — voice conversation you can interrupt, camera input ("show Gemini what you're seeing"), and real-time visual cards like maps and weather. Google notes that compatibility, availability and age restrictions vary, and some features need setup or a subscription.
DeepMind has also partnered with the visual-interpreting service Aira to tune the prototype for blind and low-vision users, with a Trusted Tester programme that pairs it with live human interpreters.
One honest note on dating it: DeepMind's page carries no launch date, because there was no launch. Project Astra is a research track, not a released product with a version number, and treating it as one is the single most common error in coverage.
How do GPT-6 Astra and Project Astra compare side by side?
| GPT-6 Astra | Google Project Astra | |
|---|---|---|
| Maker | OpenAI | Google DeepMind |
| What it actually is | A frontier large language model | A research prototype for a universal AI assistant |
| Core job | Reasoning, coding, computer use, research, document creation | Real-time camera and voice assistance, screen sharing, tool use |
| Inputs | Text and image in, text out | Live camera, screen, voice |
| Limits | 1,050,000 context window; 922,000 max input, 128,000 max output; cutoff 30 Apr 2026 | Not published — it is not a model you call |
| Launch | Released 3 September 2026 | No launch — ongoing research programme |
| Status today | Shipping; enterprise Trusted Access first, ChatGPT paid plans following | Research prototype with a limited set of trusted testers |
| How you access it | OpenAI API (gpt-6-astra, Responses API) and ChatGPT Plus, Pro, Business, Enterprise. Not on Amazon Bedrock | Waitlist for trusted testers; the capabilities reach the public through Gemini Live |
| Price | $10 / 1M input, $50 / 1M output; $20 / $75 above 272K input tokens | Not sold. No price of its own |
| Runs on | OpenAI API and ChatGPT clients | Android phones and prototype glasses |
One is a model you call with an API key and pay for per token. The other is a prototype you cannot buy, whose features reach you wearing a different name.
Why do both products use the name Astra?
"Astra" is Latin. It is the plural of astrum, and it means stars — a short, positive-sounding word with no exclusivity in software, which is why several unrelated products carry it.
On OpenAI's side, the naming is systematically celestial. Alongside gpt-6-astra, OpenAI's pricing page lists GPT-5.6 Sol (sun), GPT-5.6 Terra (earth) and GPT-5.6 Luna (moon). Within that scheme, "Astra" is the obvious name for the tier sitting above the rest.
On Google's side, Project Astra is a research codename, consistent with how DeepMind names its programmes — Genie, Veo, Imagen, Lyria, Gemini Robotics.
That is the whole story. Two organisations independently picked the same short Latin word for different things. There is no shared technology, no shared team, and no announced dispute between them.
One coincidence does make the confusion worse in search results: both are gated behind early-access programmes with near-identical names. OpenAI is rolling GPT-6 Astra out through its Trusted Access Program; Google runs a Trusted Tester waitlist for Project Astra. If you half-remember reading "Astra" and "trusted", you could plausibly have read either.
Which Astra do you actually want?
- You want to call a model from code. GPT-6 Astra. Set
modeltogpt-6-astrain a Responses API request. Project Astra has no API at all. - You are building a coding or computer-use agent. GPT-6 Astra. Computer use is one of its four listed tools, and OpenAI positions it for multistep work across code, browsers and professional software.
- You want a live camera assistant on your phone today. Neither, strictly — open Gemini Live in the Gemini app. That is the shipped surface where Project Astra's work actually reaches users.
- You want to try the prototype itself, including the glasses. Join the Project Astra trusted-tester waitlist on DeepMind's page. There is no other route in.
- You are comparing frontier models for a build decision. The real comparison is GPT-6 Astra against Google's shipping Gemini models, not against Project Astra. Start with our Gemini 3.5 complete guide and the Gemini 3.8 Flash guide for the cheap-and-fast end.
What else is called Astra?
Enough to muddy your search results. The Astra WordPress theme at wpastra.com is a widely used "fast, lightweight and customizable WordPress theme" — queries about Astra child themes, page builders or downloads almost always mean this one. The Opel Astra is a C-segment compact car built by Opel since 1991, sold as the Vauxhall Astra in the United Kingdom. If a result is about starter templates or hatchbacks, you have landed on a different Astra.
How do you tell which Astra a headline means?
If a headline mentions benchmarks, token prices or a 1M-token context window, it means OpenAI's GPT-6 Astra. If it mentions a phone camera, glasses or memory across devices, it means Google DeepMind's Project Astra. The quickest test of all: ask whether the thing has a price. Only OpenAI's does.
For a build decision, the rule follows from that. GPT-6 Astra is a purchasable, production-ready option today; Project Astra is not an option at all yet. Compare Astra to Gemini, not to Project Astra.
FAQ
Is GPT Astra the same as Google Project Astra?
No. They are unrelated products from competing companies that happen to share a name. GPT-6 Astra is OpenAI's flagship large language model, released 3 September 2026 and priced at $10 per million input tokens. Project Astra is a Google DeepMind research prototype for a real-time camera-and-voice assistant, with no price and no public release.
Who makes GPT Astra?
OpenAI. Its full name is GPT-6 Astra and its API model ID is gpt-6-astra. It sits at the top of OpenAI's line-up above GPT-5.6 Sol, Terra and Luna, and OpenAI describes it as its most capable model, built for the hardest end-to-end work across reasoning, coding, computer use, research and document creation.
What is Google Project Astra?
Project Astra is a Google DeepMind research prototype exploring what a universal AI assistant could do. Its capabilities include spatial processing, screen sharing and tool use across Search, Gmail, Calendar and Maps, plus multimodal memory that follows you between devices. It runs on Android phones and DeepMind's prototype glasses, and it is not an ordinary language model.
Is Project Astra available yet?
Not as a product. DeepMind's own page describes it as a research prototype used by a limited number of trusted testers, with a waitlist to apply. The capabilities do reach the public, but through Gemini Live in the Gemini app rather than under the Astra name. If you want the camera assistant experience today, use Gemini Live.
Is GPT-6 Astra related to Gemini?
No. GPT-6 Astra is built by OpenAI; Gemini is Google's model family. They are direct competitors. The only connection is that Project Astra, which shares a name with OpenAI's model, is a Google research programme whose features ship inside Gemini Live. Comparing GPT-6 Astra to Gemini is reasonable; comparing it to Project Astra is comparing a model to a prototype.
What does Astra mean?
Astra is Latin for "stars", the plural of astrum. OpenAI uses celestial names across its current line-up, including Sol, Terra and Luna, so Astra fits that scheme. Google uses it as a research codename. The shared name is coincidence, not a connection between the two companies.
How much does GPT-6 Astra cost?
OpenAI lists $10 per million input tokens and $50 per million output tokens. Prompts over 272,000 input tokens are billed at 2x input and 1.5x output for the whole request, which works out to $20 in and $75 out. Cached input drops to $1, and Batch halves the standard rate to $5 in and $25 out. Project Astra has no pricing because it is not sold.
