Which is better: Gemini Robotics-ER 1.6 Preview, Apertus 70B or GLM-5V-Turbo?
It is close. Our weighted score puts them within 1 points (Gemini Robotics-ER 1.6 Preview 50/100, GLM-5V-Turbo 49/100, Apertus 70B 33/100), so choose by what matters most for your work: Apertus 70B on price and GLM-5V-Turbo 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, Apertus 70B or GLM-5V-Turbo?
Apertus 70B is cheaper at $0.82 input / $2.42 output per million tokens (median across 3 API providers). 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 $1.22 per million tokens for Apertus 70B versus $1.90 for GLM-5V-Turbo (1.6× as much) and $2.00 for Gemini Robotics-ER 1.6 Preview (1.6× 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, Apertus 70B 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, Apertus 70B 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?
GLM-5V-Turbo has the largest context window at 200,000 tokens, against 131,072 for Gemini Robotics-ER 1.6 Preview and 65,536 for Apertus 70B. Maximum output per response: Gemini Robotics-ER 1.6 Preview up to 65,536, Apertus 70B up to 8,192, GLM-5V-Turbo up to 131,072 tokens.
Which can read images, PDFs, audio or video?

Are any of these open source?
Apertus 70B publishes its weights (Apache-2.0) and can be self-hosted; Gemini Robotics-ER 1.6 Preview and GLM-5V-Turbo is proprietary.
Which is newer?
Gemini Robotics-ER 1.6 Preview is the newest, released Apr 14, 2026. GLM-5V-Turbo came out Apr 1, 2026; Apertus 70B came out Sep 2, 2025. Knowledge cutoff: Gemini Robotics-ER 1.6 Preview Jan 2025, Apertus 70B Sep 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.
