Are any of these open source?
Qwen3 32B publishes its weights and can be self-hosted; GPT-5 and Gemini 2.5 Pro is proprietary.
Which is newer?
GPT-5 is the newest, released Aug 7, 2025. Gemini 2.5 Pro came out Jun 17, 2025; Qwen3 32B came out Apr 29, 2025. Knowledge cutoff: GPT-5 Sep 30, 2024, Qwen3 32B Apr 2025, Gemini 2.5 Pro Jan 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
