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 — MiniMax
MiniMax-M3 is a native multimodal model with about 428B parameters (about 23B activated) and a 1M-token context window, built on MiniMax Sparse Attention. MiniMax positions it for agentic coding, tool use and long-context work.
Model B — StepFun
Step 3.7 Flash is StepFun's open-weight vision-language Mixture-of-Experts model, 198B parameters with about 11B active per token, built for high-throughput agent workloads. It supports a 256k context and three reasoning levels.

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.
