Which should you pick?

On a typical workload, Gemini 2.5 Flash-Lite costs $70.00/mo against DeepSeek V4 Flash's $70.00/mo, essentially the same. But the ranking depends on your output-to-input ratio: output is the pricier direction for both, so an output-heavy job (code generation, long answers) widens the gap while an input-heavy one (summarization, retrieval) narrows it. Both share the same context window, so that's not a deciding factor here. Only Gemini 2.5 Flash-Lite accepts image input — decisive if your prompts include images.

These are list and routed market prices, not measured outcomes. Two models at the same rate can still cost different amounts to finish the same task, because verbose or reasoning-heavy models emit more tokens. That gap is exactly what measured cost-per-task captures.
