Too close to call
It is close. Our weighted score puts them within 3 points (Grok 4.1 Fast 71/100, Nemotron 3 Nano 30B A3B 68/100, Ministral 3 14B 63/100), so choose by what matters most for your work: Nemotron 3 Nano 30B A3B on price and Grok 4.1 Fast 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 should you choose?
Which is better: Grok 4.1 Fast, Ministral 3 14B or Nemotron 3 Nano 30B A3B?
It is close. Our weighted score puts them within 3 points (Grok 4.1 Fast 71/100, Nemotron 3 Nano 30B A3B 68/100, Ministral 3 14B 63/100), so choose by what matters most for your work: Nemotron 3 Nano 30B A3B on price and Grok 4.1 Fast 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, Grok 4.1 Fast, Ministral 3 14B or Nemotron 3 Nano 30B A3B?
Nemotron 3 Nano 30B A3B is cheaper at $0.05 input / $0.20 output per million tokens (median across 13 API providers; free on Nvidia). Grok 4.1 Fast costs $0.20 input / $0.50 output per million tokens (median across 2 API providers); Ministral 3 14B costs $0.268 input / $0.325 output per million tokens (median across 2 API providers). At a typical mix of three input tokens to one output token, that is $0.087 per million tokens for Nemotron 3 Nano 30B A3B versus $0.275 for Grok 4.1 Fast (3.1× as much) and $0.282 for Ministral 3 14B (3.2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Grok 4.1 Fast has not been scored yet, Ministral 3 14B has not been scored yet and Nemotron 3 Nano 30B A3B has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Grok 4.1 Fast, Ministral 3 14B and Nemotron 3 Nano 30B A3B 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 4.1 Fast has the largest context window at 2,000,000 tokens, against 262,144 for Ministral 3 14B and 262,144 for Nemotron 3 Nano 30B A3B. Maximum output per response: Grok 4.1 Fast up to 30,000, Ministral 3 14B up to 262,144, Nemotron 3 Nano 30B A3B up to 262,144 tokens.
Which can read images, PDFs, audio or video?
Grok 4.1 Fast accepts text and images; Ministral 3 14B accepts text and images; Nemotron 3 Nano 30B A3B accepts text. Grok 4.1 Fast handles the widest range of inputs.
Are any of these open source?
Ministral 3 14B and Nemotron 3 Nano 30B A3B publishes its weights (Apache 2.0) and can be self-hosted; Grok 4.1 Fast is proprietary.
Which is newer?
Nemotron 3 Nano 30B A3B is the newest, released Dec 15, 2025. Ministral 3 14B came out Dec 2, 2025; Grok 4.1 Fast came out Nov 19, 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.
