Original GitHub issue: https://github.com/ollama/ollama/issues/5189

What is the issue?

I was testing out Deepseek Coder V2 using the Ollama /api/chat endpoint and I get the following error. Does this model in general support chat?

Model:
deepseek-coder-v2:16b-lite-instruct-q4_0

Error:
ERROR [validate_model_chat_template] The chat template comes with this model is not yet supported, falling back to chatml. This may cause the model to output suboptimal responses | tid="0x1ee4b4c00" timestamp=1718899061

The request ends up failing, but that is captured from the Ollama log files.
