Are any of these open source?
Kimi K2.6 publishes its weights and can be self-hosted; Gemini Robotics-ER 1.6 Preview and GLM-5-Turbo is proprietary.
Which is newer?
Kimi K2.6 is the newest, released Apr 21, 2026. Gemini Robotics-ER 1.6 Preview came out Apr 14, 2026; GLM-5-Turbo came out Mar 16, 2026. Knowledge cutoff: Gemini Robotics-ER 1.6 Preview Jan 2025, Kimi K2.6 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.
