Atria Dawn Preview: new users may receive about 100 million free tokens

Atria Dawn Preview is an API from a team associated with Shanghai AI Laboratory, aimed at research, engineering, and longer-running agent tasks.

What is available

• Official API: The service documents Chat Completions, Messages, and Responses endpoints. The console uses a Google account for sign-in and API key creation.
• New-user quota: A community report mentions about 100 million free tokens for new users. This is not a fixed pricing-page promise, so check the quota and usage panel after signing in.
• Context: The official model description lists roughly 256K context.

How to start

1. Open the Atria API console.
2. Sign in with a Google account.
3. Create an API key in the API Key section and store it safely; the key is shown only once.
4. Follow the official API documentation to configure Chat, Messages, or Responses in your client.

Notes

• Quotas, rate limits, and model availability may change during the Preview period. Check the console if you receive a 429 or quota error.
• Never publish an API key.
• The model overview is available at atria-asi.com, with model files at Hugging Face.
