DeepSeek V3.2 Exp lists $0.27/M in and $0.41/M out (no cache pricing); Gemini 2.5 Flash lists $0.3/M and $2.5/M (reads $0.03/M). Headlines don't settle it — the blend of your input/output mix and each model's caching does.
The answer flips: with 1,000 input tokens, the two bills cross at ~63 output tokens per request (ratio 0.06). Below it one wins, above it the other — check which side your workload sits on before committing.

Why not just compare the advertised prices?

When does the cheaper model flip?
At 1,000 input tokens with 60% cached, the bills cross at ~63 output tokens per request. Short-answer workloads favor one side, long-generation workloads the other — that's the number to check, not the headline.
Is the cheaper model the right choice?
Only if quality holds on your task.

Context windows and caching support (both shown above) can also decide it outright.
