## The problem

Issue deepseek-ai/awesome-deepseek-integration#11 (closed, 9 comments): VS Code Continue extension hit a 404 against the DeepSeek API. The reporter found the cause themselves: DeepSeek's API is only compatible with the OpenAI /v1/chat/completions endpoint, not the legacy /v1/completions endpoint.

## The verified resolution

Reporter fixed it by adding "useLegacyCompletionsEndpoint": false to the Continue config. Collaborator DillionApple confirmed: 'Currently, we do not supply the /v1/completions API.'

## Rule of thumb

DeepSeek does not support the legacy completions endpoint; always point OpenAI-compat tools at /v1/chat/completions.
