Which is better: GPT-5.6 Sol, MiniMax-M3.1-Flash or Nemotron 3.5 Super 120B A12B?
MiniMax-M3.1-Flash is the better all-round choice, scoring 70/100 against Nemotron 3.5 Super 120B A12B (59) and GPT-5.6 Sol (39). GPT-5.6 Sol wins on 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, GPT-5.6 Sol, MiniMax-M3.1-Flash or Nemotron 3.5 Super 120B A12B?
MiniMax-M3.1-Flash is cheaper at $0.15 input / $0.60 output per million tokens (official MiniMax (minimax.io) API price). Nemotron 3.5 Super 120B A12B costs $0.20 input / $0.50 output per million tokens (median across 1 API provider); GPT-5.6 Sol costs $4.00 input / $20.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $0.263 per million tokens for MiniMax-M3.1-Flash versus $0.275 for Nemotron 3.5 Super 120B A12B (1× as much) and $8.00 for GPT-5.6 Sol (30× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. GPT-5.6 Sol has an ECI of 162.6, MiniMax-M3.1-Flash has not been scored yet and Nemotron 3.5 Super 120B A12B has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-5.6 Sol, MiniMax-M3.1-Flash and Nemotron 3.5 Super 120B A12B 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?
GPT-5.6 Sol and Nemotron 3.5 Super 120B A12B have the largest context windows (1,050,000 and 1,048,576 tokens), against 1,000,000 for MiniMax-M3.1-Flash. Maximum output per response: GPT-5.6 Sol up to 128,000, MiniMax-M3.1-Flash up to 512,000, Nemotron 3.5 Super 120B A12B up to 131,072 tokens.
Which can read images, PDFs, audio or video?
GPT-5.6 Sol accepts text, images and PDFs; MiniMax-M3.1-Flash accepts text, images and video; Nemotron 3.5 Super 120B A12B accepts text. GPT-5.6 Sol handles the widest range of inputs.
Are any of these open source?
Nemotron 3.5 Super 120B A12B publishes its weights and can be self-hosted; GPT-5.6 Sol and MiniMax-M3.1-Flash is proprietary.
Which is newer?

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 Nov 2, 2026.
