Which is better: Grok Build 0.1, Gemini Robotics-ER 1.6 Preview or MiniMax-M2.7-highspeed?

Grok Build 0.1 is the better all-round choice, scoring 54/100 against Gemini Robotics-ER 1.6 Preview (50) and MiniMax-M2.7-highspeed (41). It leads on context window. Gemini Robotics-ER 1.6 Preview wins on inputs & features. MiniMax-M2.7-highspeed wins on price. 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, Grok Build 0.1, Gemini Robotics-ER 1.6 Preview or MiniMax-M2.7-highspeed?

MiniMax-M2.7-highspeed is cheaper at $0.60 input / $2.40 output per million tokens (official MiniMax (minimax.io) API price). Grok Build 0.1 costs $1.00 input / $2.00 output per million tokens (official xAI 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 $1.05 per million tokens for MiniMax-M2.7-highspeed versus $1.25 for Grok Build 0.1 (1.2× as much) and $2.00 for Gemini Robotics-ER 1.6 Preview (1.9× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Grok Build 0.1 has not been scored yet, Gemini Robotics-ER 1.6 Preview has not been scored yet and MiniMax-M2.7-highspeed has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Grok Build 0.1, Gemini Robotics-ER 1.6 Preview and MiniMax-M2.7-highspeed 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?

Grok Build 0.1 has the largest context window at 256,000 tokens, against 204,800 for MiniMax-M2.7-highspeed and 131,072 for Gemini Robotics-ER 1.6 Preview. Maximum output per response: Grok Build 0.1 up to 256,000, Gemini Robotics-ER 1.6 Preview up to 65,536, MiniMax-M2.7-highspeed up to 131,072 tokens.

Which can read images, PDFs, audio or video?

Are any of these open source?

MiniMax-M2.7-highspeed publishes its weights and can be self-hosted; Grok Build 0.1 and Gemini Robotics-ER 1.6 Preview is proprietary.

Which is newer?

Grok Build 0.1 is the newest, released Apr 16, 2026. Gemini Robotics-ER 1.6 Preview came out Apr 14, 2026; MiniMax-M2.7-highspeed came out Mar 18, 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.
