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 — OpenAI
GPT-5 is a reasoning model from OpenAI, released in the API on August 7, 2025 (snapshot gpt-5-2025-08-07). It takes text and image input, returns text, and has configurable reasoning effort.
Model B — AI21 Labs
Jamba Large 1.7 is the Large model of AI21 Labs’ Jamba family, released on July 3, 2025, built on its hybrid SSM-Transformer (Mamba-Transformer) architecture with a 256K-token context window; AI21 says version 1.7 improves grounding and instruction-following.

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.
