What you get

Serverless API over open models, whose Free plan grants $1 of credit every four weeks for open models of up to 7B parameters, one request at a time, with no billing

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

Open models up to 7B: $1/4 weeks; 1 request at once per account

Credits expire four weeks after grant. The free balance supports open models up to 7B parameters. Closed-model docs conflict between provider prices plus a platform fee and BYOK billed directly by the provider, so the free dollar does not establish bundled closed-model access. Larger open models require paid credit and a paid plan.

Where it is offered

The vendor names no country it keeps the offer from (source, read 2026-09-26).

Base URL: https://api.bytez.com/models/v2/openai/v1
Key: BYTEZ_API_KEY — get one at https://bytez.com/api
Callable ids: Qwen/Qwen3-4B
Note: model ids are Hugging Face ids, Qwen/Qwen3-4B being the docs’ example; the OpenAI SDK examples pass the key as the api key and the docs’ curl sends it bare in Authorization. /v1/models answers 401 without a key, and closed-source models need a provider key of your own

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

curl -s https://api.bytez.com/models/v2/openai/v1/chat/completions \
  -H "Authorization: Bearer $BYTEZ_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{"model":"Qwen/Qwen3-4B","messages":[{"role":"user","content":"2+2? MAKE NO MISTAKES."}]}'
