Oh My Pi is a terminal AI coding agent. As of v14.5 it ships DeepSeek V4 model entries, but the built-in compat is incomplete — a custom models.yml is still required for reliable use. Prerequisites ​ Install Oh My Pi: https://github.com/can1357/oh-my-pi#installation Get an API key from the DeepSeek Platform : Configuration ​ Create ~/.omp/agent/models.yml : Configuration notes ​ Thinking mode ​ Three critical compat fields ​

These three fields are essential. Without them, DeepSeek V4 will return 400 errors when using tools in thinking mode. For faster responses: Switch models inside Oh My Pi with /model or Ctrl+L . Do not rely on the built-in model entries. Recent builds list deepseek-v4-pro and deepseek-v4-flash via omp --list-models deepseek , but they lack the three critical compat fields above. Long thinking-mode conversations with tool calls will 400. Always use the models.yml configuration shown above. Oh My Pi does not currently have a DeepSeek OAuth /login entry. API keys must be provided via the DEEPSEEK_API_KEY environment variable or the apiKey field in models.yml . When using DeepSeek V4 through unofficial providers (DeepInfra, KiloCode, NVIDIA NIM, Zenmux, etc.) via OpenAI-compatible endpoints, reasoning_content replay behavior varies and compatibility is unresolved. Prefer the official api.deepseek.com endpoint. In models.yml , compat replaces the built-in block wholesale — it does not merge. Always specify the full set of compat fields.
