DeepSeek-V4-Flash-0731
Just one day after OpenAI has dropped the prices of their smallest model by 80%, the whale dropped an update to their V4 Flash model, beating Luna at the pareto frontier. The bigger model is not updated yet, so it remains to be seen where it will land in terms of performance. For the initial V4 releases, the Flash version was the star of the show in terms of performance per parameter, while Pro was rather underwhelming.
Relative Adoption Metric contextualizes downloads against the model's size bucket.
OpenRouter publishes daily token totals for its ~50 most-served models. Days missing from the chart mean DeepSeek-V4-Flash-0731 fell below that cutoff — not zero usage. OpenRouter logs usage separately per dated model version and per variant (like ":free"); the hub combines provider variants while keeping separately cataloged releases distinct.
