Free Models

DDTokens may provide free models for testing, integration validation, and light use. Free models are not suitable for production-critical services.

Suitable Uses

Free models are suitable for:

• Verifying the API key and base_url configuration.
• Testing a client integration.
• Running infrequent, non-critical development tasks.
• Evaluating a model's response format.

Usage

If the platform supports a free-model suffix, you can usually append :free to the model name:

gpt-4o-mini:free

Available models, naming rules, and daily capacity are determined by the dashboard.

Capacity Limits

Free models usually have stricter limits, including:

• Requests per minute.
• Requests per day.
• Maximum concurrency.
• Available model selection.

When the free quota is exhausted, requests may return a rate-limit or insufficient-quota error. Wait for the quota to refresh or switch to a paid model.

Production Recommendations

Do not depend on free models in production. Production services should use paid models and configure:

• Request retries.
• A rate-limiting queue.
• Logging.
• Cost alerts.
