Accessing Closed Source Models

Bytez enables you to interact with proprietary chat models by OpenAI, Anthropic, Cohere, Google, and Mistral

To use these models, you’ll need two keys:

  1. Your Bytez API Key: Obtained as described above.
  2. Provider Key: The key specific to the provider you want to access (e.g., OpenAI API key).

Example Headers

Authorization: Key your-bytez-api-key
Provider-key: your-provider-key

​
Notes

  1. No Additional Charges: Bytez does not charge for accessing proprietary models; however, the respective provider’s billing applies.
  2. Seamless Integration: You can interact with closed-source models using the same standardized input structure as open-source models.
