AI Model Comparison
Side-by-side comparison of pricing, context window, benchmarks, capabilities, and license. Every figure comes from the developer's own pages, last checked on ; each model's page lists its sources. A figure we could not source shows as a dash.
Model A — DeepSeek
DeepSeek-V4.1-Flash is a 552B-parameter Mixture-of-Experts model with native visual understanding, which DeepSeek calls the smallest model in its new architecture family. It is served on the DeepSeek API under the model name deepseek-flash, with open weights under the MIT License.
Model B — Google DeepMind
Gemini 3.5 Flash-Lite is a low-latency, lower-cost Gemini model, made generally available on July 21, 2026, for subagent tasks, document parsing and high-volume workflows. It takes text, image, video, audio and PDF input and returns text.

Bold green values indicate the winner on that dimension where comparison is meaningful (lower price wins; bigger context wins; more open license wins; newer date wins). Prices are the ones each developer lists today; a model it no longer prices has none.
