I have used both **Pi** and **OpenCode** in the past, and although I liked Pi I tended to just use OpenCode out of habit. OpenCode has become more efficient over time, and it works well enough. However, Pi seems to be **even faster** and more minimal, and also is a more pure open source project.

One thing that concerns me about OpenCode is that it seems to be interested in selling **AI subscriptions**. If I wanted to subscribe to something like that, I could just use OpenAI or Anthropic. I want to focus more on **local model usage** through `llama-cpp`

.

I used **Laguna XS 2.1** on Pi, and it was even faster than in OpenCode. If you want my opinion, Laguna XS 2.1 is the best coding model for a 12 GB Nvidia GPU system. It is 20.3 GB and runs at over 40 tokens per second in `llama-cpp`

.

Some projects, like Ollama and OpenCode, seem focused on selling **AI subscriptions**. This is fine, but if you are not interested in that, it is probably best to use other software like `llama-cpp`

and Pi.
