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 — NVIDIA
Nemotron 3.5 Lightning is a 30B-parameter (3B active) open-weight language model from NVIDIA, released on August 11, 2026 with a hybrid Mamba-2 and mixture-of-experts architecture. NVIDIA says it supports up to 1M tokens of context and is ready for commercial use.
Model B — ByteDance Seed

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.
