Too close to call
It is close. Our weighted score puts them within a point (Ministral 8B Instruct 57/100, Llama-3.1-8B-Instruct 56/100, Step 1 (32K) 18/100), so choose by what matters most for your work: Ministral 8B Instruct on price and Ministral 8B Instruct 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: Llama-3.1-8B-Instruct, Ministral 8B Instruct or Step 1 (32K)?
It is close. Our weighted score puts them within a point (Ministral 8B Instruct 57/100, Llama-3.1-8B-Instruct 56/100, Step 1 (32K) 18/100), so choose by what matters most for your work: Ministral 8B Instruct on price and Ministral 8B Instruct 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, Llama-3.1-8B-Instruct, Ministral 8B Instruct or Step 1 (32K)?
Ministral 8B Instruct is cheaper at $0.15 input / $0.15 output per million tokens (median across 1 API provider). Llama-3.1-8B-Instruct costs $0.152 input / $0.167 output per million tokens (median across 9 API providers); Step 1 (32K) costs $2.05 input / $9.59 output per million tokens (official StepFun (Global) API price). At a typical mix of three input tokens to one output token, that is $0.15 per million tokens for Ministral 8B Instruct versus $0.156 for Llama-3.1-8B-Instruct (1× as much) and $3.94 for Step 1 (32K) (26× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Llama-3.1-8B-Instruct has an ECI of 116.6, Ministral 8B Instruct has not been scored yet and Step 1 (32K) has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Llama-3.1-8B-Instruct, Ministral 8B Instruct and Step 1 (32K) 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?
Ministral 8B Instruct has the largest context window at 131,072 tokens, against 128,000 for Llama-3.1-8B-Instruct and 32,768 for Step 1 (32K). Maximum output per response: Llama-3.1-8B-Instruct up to 4,096, Ministral 8B Instruct up to 8,192, Step 1 (32K) up to 32,768 tokens.
Which can read images, PDFs, audio or video?
Llama-3.1-8B-Instruct accepts text; Ministral 8B Instruct accepts text; Step 1 (32K) accepts text. They handle the same number of input types.
Are any of these open source?
Llama-3.1-8B-Instruct and Ministral 8B Instruct publishes its weights (Mistral Research License) and can be self-hosted; Step 1 (32K) is proprietary.
Which is newer?
Step 1 (32K) is the newest, released Jan 1, 2025. Ministral 8B Instruct came out Oct 16, 2024; Llama-3.1-8B-Instruct came out Jul 23, 2024. Knowledge cutoff: Llama-3.1-8B-Instruct Dec 2023, Step 1 (32K) Jun 2024.
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.
