# What tends to break when moving an app to DeepSeek’s OpenAI-compatible API?

I’m considering switching an application from an OpenAI endpoint to DeepSeek’s OpenAI-compatible API. The basic request shape looks familiar, but I don’t want to assume every SDK option or response field behaves identically.

For people who have made this move, which parts needed adjustment: endpoint configuration, model names, error handling, or something less obvious? I’m particularly interested in **DeepSeek API migration issues** that only showed up after deployment.
