DeepSeek's OpenAI-compatible chat schema accepts text content rather than OpenAI vision content parts, so forwarding Anthropic image blocks as image_url makes the upstream reject the request before the model can answer. Keep normal OpenAI Chat vision behavior as the default, but switch known DeepSeek-compatible chat proxy requests to a text-only conversion that preserves prompt text and replaces image payloads with a small omission marker. Constraint: DeepSeek official Chat Completions docs list user message content as string text, while its Anthropic compatibility table marks image blocks as not supported. Rejected: Expand unsupported-image error string matching only | it still surfaces the first turn as an API error and depends on provider wording.
