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-6.1 Sol is an OpenAI reasoning model released on September 29, 2026 that OpenAI says delivers near-Astra performance at a lower cost for complex coding, computer use and professional work. It takes text and image input and returns text.
Model B — Reflection AI
Beam is Reflection AI's first open-weight model, a 501B-parameter sparse mixture-of-experts model with 23B active parameters, built for coding, reasoning and agentic work. Announced on October 5, 2026, its weights were released on Hugging Face under Apache 2.0; it takes and returns text only.

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.
