Which should you choose?
Which is better: Llama-3.1-8B-Instruct or Step 1 (32K)?
Llama-3.1-8B-Instruct is the better all-round choice, scoring 56/100 against Step 1 (32K) (18). It leads on price and context window. 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 or Step 1 (32K)?
Llama-3.1-8B-Instruct is cheaper at $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 $0.156 per million tokens for Llama-3.1-8B-Instruct versus $3.94 for Step 1 (32K) (25× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Llama-3.1-8B-Instruct has an ECI of 116.6 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 and Step 1 (32K) yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.
Which has the bigger context window?

Which can read images, PDFs, audio or video?
Llama-3.1-8B-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 publishes its weights and can be self-hosted; Step 1 (32K) is proprietary.
Which is newer?
Step 1 (32K) is the newest, released Jan 1, 2025. 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.
