Together AI	Deploy open-source models at scale using Together AI's optimized inference platform with serverless GPU infrastructure

Together AI

Together AI provides access to open-source models through an API compatible with OpenAI's interface.

OpenAI Compatibility

Together AI's API is compatible with OpenAI's API, which means all parameters available in the OpenAI provider work with Together AI.

Basic Configuration

Configure a Together AI model in your promptfoo configuration:

# yaml-language-server: $schema=https://promptfoo.dev/config-schema.json
providers:
  - id: togetherai:meta-llama/Llama-4-Scout-Instruct
    config:
      temperature: 0.7

The provider requires an API key stored in the TOGETHER_API_KEY environment variable.
