Which should you choose?
Which is better: Nemotron 3 Nano Omni 30B A3B Reasoning, Perceptron Mk1 or Step 3.7 Flash?
Nemotron 3 Nano Omni 30B A3B Reasoning is the better all-round choice, scoring 67/100 against Step 3.7 Flash (63) and Perceptron Mk1 (45). 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, Nemotron 3 Nano Omni 30B A3B Reasoning, Perceptron Mk1 or Step 3.7 Flash?
Nemotron 3 Nano Omni 30B A3B Reasoning is cheaper at $0.25 input / $0.85 output per million tokens (median across 4 API providers; free on Nvidia). Step 3.7 Flash costs $0.20 input / $1.15 output per million tokens (official StepFun (Global) API price); Perceptron Mk1 costs $0.15 input / $1.50 output per million tokens (median across 3 API providers). At a typical mix of three input tokens to one output token, that is $0.40 per million tokens for Nemotron 3 Nano Omni 30B A3B Reasoning versus $0.438 for Step 3.7 Flash (1.1× as much) and $0.487 for Perceptron Mk1 (1.2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Nemotron 3 Nano Omni 30B A3B Reasoning has not been scored yet, Perceptron Mk1 has not been scored yet and Step 3.7 Flash has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Nemotron 3 Nano Omni 30B A3B Reasoning, Perceptron Mk1 and Step 3.7 Flash yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Perceptron Mk1 does not support tool calling, which most coding agents need.
Which has the bigger context window?
Nemotron 3 Nano Omni 30B A3B Reasoning and Step 3.7 Flash have the largest context windows (256,000 and 256,000 tokens), against 32,768 for Perceptron Mk1. Maximum output per response: Nemotron 3 Nano Omni 30B A3B Reasoning up to 65,536, Perceptron Mk1 up to 8,192, Step 3.7 Flash up to 256,000 tokens.
Which can read images, PDFs, audio or video?
Nemotron 3 Nano Omni 30B A3B Reasoning accepts text, images, audio and video; Perceptron Mk1 accepts text, images and video; Step 3.7 Flash accepts text, images and video. Nemotron 3 Nano Omni 30B A3B Reasoning handles the widest range of inputs.
Are any of these open source?
Nemotron 3 Nano Omni 30B A3B Reasoning and Step 3.7 Flash publishes its weights and can be self-hosted; Perceptron Mk1 is proprietary.
Which is newer?
Step 3.7 Flash is the newest, released May 29, 2026. Perceptron Mk1 came out May 12, 2026; Nemotron 3 Nano Omni 30B A3B Reasoning came out Apr 28, 2026. Knowledge cutoff: Step 3.7 Flash Mar 1, 2026.
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.
