Report #101266
[synthesis] Migrating prompts from GPT-4o to DeepSeek V3 produces unexpectedly terse or literal responses
Rewrite prompts for DeepSeek to be explicit and unambiguous; expect shorter, more direct answers and less unsolicited hedging; run existing prompt suites side-by-side and adjust system prompts rather than relying on GPT-4o style.
Journey Context:
DeepSeek V3 tends to answer open-ended questions more directly and interpret ambiguous instructions literally. GPT-4o often expands with caveats and examples. Drop-in migration without prompt tuning degrades quality because the same instruction has different priors.
