Too close to call
It is close. Our weighted score puts them within a point (Seed Evolving 50/100, Gemini Robotics-ER 1.6 Preview 50/100, GLM-5V-Turbo 49/100), so choose by what matters most for your work: Seed Evolving on price and Seed Evolving for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which should you choose?
Which is better: Gemini Robotics-ER 1.6 Preview, Seed Evolving or GLM-5V-Turbo?
It is close. Our weighted score puts them within a point (Seed Evolving 50/100, Gemini Robotics-ER 1.6 Preview 50/100, GLM-5V-Turbo 49/100), so choose by what matters most for your work: Seed Evolving on price and Seed Evolving for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Gemini Robotics-ER 1.6 Preview, Seed Evolving or GLM-5V-Turbo?
Seed Evolving is cheaper at $0.891 input / $4.45 output per million tokens (official Volcengine Ark API price). GLM-5V-Turbo costs $1.20 input / $4.00 output per million tokens (official Z.AI API price); Gemini Robotics-ER 1.6 Preview costs $1.00 input / $5.00 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $1.78 per million tokens for Seed Evolving versus $1.90 for GLM-5V-Turbo (1.1× as much) and $2.00 for Gemini Robotics-ER 1.6 Preview (1.1× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Gemini Robotics-ER 1.6 Preview has not been scored yet, Seed Evolving has not been scored yet and GLM-5V-Turbo has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Gemini Robotics-ER 1.6 Preview, Seed Evolving and GLM-5V-Turbo yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.
Which has the bigger context window?
Seed Evolving has the largest context window at 256,000 tokens, against 200,000 for GLM-5V-Turbo and 131,072 for Gemini Robotics-ER 1.6 Preview. Maximum output per response: Gemini Robotics-ER 1.6 Preview up to 65,536, Seed Evolving up to 256,000, GLM-5V-Turbo up to 131,072 tokens.
Which can read images, PDFs, audio or video?
Gemini Robotics-ER 1.6 Preview accepts text, images, audio and video; Seed Evolving accepts text, images and video; GLM-5V-Turbo accepts text, images, PDFs and video. Gemini Robotics-ER 1.6 Preview handles the widest range of inputs.
Are any of these open source?
No. Gemini Robotics-ER 1.6 Preview, Seed Evolving and GLM-5V-Turbo are proprietary and only available through APIs and apps.
Which is newer?
Seed Evolving is the newest, released Jun 23, 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.
