Gemini Robotics-ER 1.6 Preview accepts text, images, audio and video; Muse Spark 1.1 accepts text, images, PDFs and video; GLM-5V-Turbo accepts text, images, PDFs and video. They handle the same number of input types.
Are any of these open source?
No. Gemini Robotics-ER 1.6 Preview, Muse Spark 1.1 and GLM-5V-Turbo are proprietary and only available through APIs and apps.
Which is newer?
Muse Spark 1.1 is the newest, released Jul 9, 2026. Gemini Robotics-ER 1.6 Preview came out Apr 14, 2026; GLM-5V-Turbo came out Apr 1, 2026. Knowledge cutoff: Gemini Robotics-ER 1.6 Preview 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.
