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 — Google DeepMind
Gemini 3.8 Flash is a model from Google, made generally available on September 2, 2026, which Google describes as its most intelligent Flash model, for long-horizon software engineering, autonomous agents and complex enterprise workflows. It takes text, image, video, audio and PDF input and returns text, with thinking support.
Model B — Moonshot AI
Kimi K3 is Moonshot AI's 2.8-trillion-parameter open-weight Mixture-of-Experts model with native vision and a 1-million-token context window, built on Kimi Delta Attention and Attention Residuals. On the API it always reasons, with configurable reasoning effort.

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.
