What you get

OpenAI-compatible API for the Toast 1 knowledge and search model, with $5 in one-time Starter credits and no card required

Free models

The free offer is a budget for model usage across the catalog. See Limits for its conditions and Connect for API details, where available.

Limits, in the vendor’s words

Starter credits: $5 once per service plan

Create an account and an API key; a restricted key needs the Completions scope. Starter credits do not renew, and their expiry is not published. They fund usage at the standard rates; hosted searches and data storage have separate charges against the balance. The published search and upload rate limits do not establish a Chat Completions allowance. The terms license use for internal business purposes. Privacy and security pages exclude model training, but the Free-tier terms permit it; this conflict is unresolved. Both legal policies specify indefinite retention of Free usage data. The API documents store=false for response-content retention, but its relationship to the Free-tier legal retention rule is not established.

Where it is offered

The vendor names no country it keeps the offer from (source, read 2026-11-04).

What happens to what you send

Training policy not established. In the vendor’s words: “Data collected under the Free Tier is retained indefinitely.” (source).

Connect

• Base URL: https://api.mixedbread.com/v1
• Key: MIXEDBREAD_API_KEY — get one at https://platform.mixedbread.com/platform?next=api-keys
• Callable ids: toast-1
• Note: toast-1 is a specialized model for knowledge questions and repository investigations. The vendor documents using it as a primary model or subagent in OpenCode. It consumes the Starter credit rather than providing an individually free model.

Try it from your terminal with your key in MIXEDBREAD_API_KEY — it goes from your machine to the vendor and nowhere else:

curl -s https://api.mixedbread.com/v1/chat/completions \
  -H "Authorization: Bearer $MIXEDBREAD_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{"model":"toast-1","messages":[{"role":"user","content":"2+2? MAKE NO MISTAKES."}]}'
