# Models

> Supported models, providers, and BYOK options.

Tembo supports multiple model providers across coding agents. You can use Tembo-hosted models with [Max](/features/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, and AWS Bedrock credentials.
* Tembo still handles orchestration, session context, sandbox execution, and PR automation.

### Bedrock BYOK support

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**.
