04 — Questions

Which should you choose?

Which is better: Muse Spark 1.1, Gemini Robotics-ER 1.6 Preview or Gemini 3.6 Flash?

Gemini 3.6 Flash is the better all-round choice, scoring 63/100 against Muse Spark 1.1 (57) and Gemini Robotics-ER 1.6 Preview (50). It leads on price and inputs & features. 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, Muse Spark 1.1, Gemini Robotics-ER 1.6 Preview or Gemini 3.6 Flash?

Gemini 3.6 Flash is cheaper at $0.75 input / $3.75 output per million tokens (official Google API price). Muse Spark 1.1 costs $1.25 input / $4.25 output per million tokens (official Meta 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 $1.50 per million tokens for Gemini 3.6 Flash versus $2.00 for Muse Spark 1.1 (1.3× as much) and $2.00 for Gemini Robotics-ER 1.6 Preview (1.3× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Muse Spark 1.1 has an ECI of 154.3, Gemini Robotics-ER 1.6 Preview has not been scored yet and Gemini 3.6 Flash has an ECI of 154.3.

Which is better for coding?

There are no published SWE-bench Verified results for Muse Spark 1.1, Gemini Robotics-ER 1.6 Preview and Gemini 3.6 Flash 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?

Muse Spark 1.1 and Gemini 3.6 Flash have the largest context windows (1,048,576 and 1,048,576 tokens), against 131,072 for Gemini Robotics-ER 1.6 Preview. Maximum output per response: Muse Spark 1.1 up to 131,072, Gemini Robotics-ER 1.6 Preview up to 65,536, Gemini 3.6 Flash up to 65,536 tokens.

Which can read images, PDFs, audio or video?

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.
