 - 100% open source
 - Not coupled to any provider. Although we recommend the models we provide through [OpenCode Zen](https://opencode.ai/zen), OpenCode can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
