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 — LG AI Research
EXAONE 4.5 (33B) is LG AI Research’s first open-weight vision-language model, released on April 9, 2026, adding a dedicated visual encoder to the EXAONE 4.0 framework; LG reports strength in document understanding and Korean contextual reasoning.
Model B — ByteDance Seed
Seed2.1 Turbo is the efficient, high-throughput model of ByteDance Seed's Seed2.1 family, with deep reasoning, multimodal understanding and tool use and a 256K context, offered on BytePlus ModelArk as Dola-Seed-2.1-Turbo.

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.
