Gemini 3.8 Flash vs DeepSeek V4-Pro-0813
Values come from Gemini 3.8 Flash and DeepSeek V4-Pro-0813, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- Identical — both accept 1.0M tokens, so context length is not a reason to pick either.
- Input price
- DeepSeek V4-Pro-0813 at $0.66/M against $0.75/M — 1.1× cheaper to feed.
- Output price
- DeepSeek V4-Pro-0813 at $1.98/M against $3.75/M — 1.9× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- DeepSeek V4-Pro-0813 publishes weights (MIT (open-weight, as reported)); Gemini 3.8 Flash is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Gemini 3.8 Flash shipped 20 days after DeepSeek V4-Pro-0813 (2026-09-02 vs 2026-08-13).
