Tembo supports multiple model providers across coding agents. You can use Tembo-hosted models with Max, or connect your own keys with BYOK (Bring Your Own Key).

​
BYOK (Bring Your Own Key)

BYOK lets your workspace call models with your own provider credentials instead of Tembo-managed credentials.
  • Add keys in Settings -> Models -> API Keys.
  • You can connect OpenAI, Anthropic, Cursor, Amp, AWS Bedrock, and GCP Vertex AI credentials.
  • Tembo still handles orchestration, session context, sandbox execution, and PR automation.
BYOK inference costs $0 through Tembo. Sessions still use billable cloud VM compute, which draws from your workspace’s usage allowance.

​
Switch a model between BYOK and Tembo Managed Inference

Workspace admins can change the inference provider for individual models from Settings -> Models. In Available Models, use the model’s Inference dropdown to choose BYOK or Tembo Managed Inference, when those options are available for that model and workspace.

Tembo supports BYOK with Amazon Bedrock. To enable it, add:
  • AWS Access Key ID
  • AWS Secret Access Key
  • AWS Region
in Settings -> Models -> API Keys -> AWS Bedrock.

  • Project ID
  • Location
in Settings -> Models -> API Keys -> GCP Vertex AI.

Supported models

The table below reflects the models currently supported by Tembo.
Model availability can vary by agent and workspace configuration. If a model is disabled in your workspace, it will not appear in agent pickers until re-enabled.
