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 — Black Forest Labs
FLUX 3 Image is the image generation and editing model of Black Forest Labs’ FLUX 3 family, released on October 1, 2026. One endpoint generates or edits images, takes up to ten reference images and bounding-box layouts in the prompt, and outputs up to 4K (about 16 megapixels). Black Forest Labs also licenses the weights commercially for companies that run it on their own infrastructure.
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.
