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 — Z.ai (Zhipu AI)
GLM-5.3-Flash is the first natively multimodal model in Z.ai's GLM-5 series, with 320B total and 18B activated parameters and a hybrid of linear and sparse attention. Its weights are released under the MIT licence.

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.
