Models

All models are available on every plan. Rate limits (RPM and TPM) are set at the key level, not per model.

List models

Query the live model list:

curl https://api.cheapestinference.com/v1/models \
  -H "Authorization: Bearer YOUR_API_KEY"

This returns the full list of available models. The response follows the OpenAI /v1/models format.

To get details about a specific model:

curl https://api.cheapestinference.com/v1/models/gpt-4o-mini \
  -H "Authorization: Bearer YOUR_API_KEY"

Note

The model list above is a snapshot. The authoritative list comes from GET /v1/models. Models may be added or updated without notice. You can also browse models at app.cheapestinference.com/models.

Using models

Specify the model ID in your request:

# OpenAI SDK — any model
response = client.chat.completions.create(
    model="deepseek-chat",  # or "gpt-4o", "kimi-2.5", etc.
    messages=[{"role": "user", "content": "Hello"}]
)

# Anthropic SDK — Claude models
message = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello"}]
)

All models work through both the OpenAI endpoint (/v1/chat/completions) and the Anthropic endpoint (/anthropic/v1/messages). The API handles format translation automatically.
