Which should you choose?
Which is better: solar-mini, DeepSeek-R1 or Pixtral 12B?
Pixtral 12B is the better all-round choice, scoring 64/100 against solar-mini (52) and DeepSeek-R1 (39). It leads 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, solar-mini, DeepSeek-R1 or Pixtral 12B?
solar-mini is cheaper at $0.15 input / $0.15 output per million tokens (official Upstage API price). Pixtral 12B costs $0.15 input / $0.15 output per million tokens (official Mistral API price); DeepSeek-R1 costs $0.70 input / $2.60 output per million tokens (median across 11 API providers). At a typical mix of three input tokens to one output token, that is $0.15 per million tokens for solar-mini versus $0.15 for Pixtral 12B (1× as much) and $1.18 for DeepSeek-R1 (7.8× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. solar-mini has not been scored yet, DeepSeek-R1 has an ECI of 139.0 and Pixtral 12B has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for solar-mini, DeepSeek-R1 and Pixtral 12B 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?
DeepSeek-R1 and Pixtral 12B have the largest context windows (128,000 and 128,000 tokens), against 32,768 for solar-mini. Maximum output per response: solar-mini up to 4,096, DeepSeek-R1 up to 32,768, Pixtral 12B up to 128,000 tokens.
Which can read images, PDFs, audio or video?
solar-mini accepts text; DeepSeek-R1 accepts text; Pixtral 12B accepts text and images. Pixtral 12B handles the widest range of inputs.
Are any of these open source?
DeepSeek-R1 and Pixtral 12B publishes its weights and can be self-hosted; solar-mini is proprietary.
Which is newer?
DeepSeek-R1 is the newest, released Jan 20, 2025. Pixtral 12B came out Sep 1, 2024; solar-mini came out Jun 12, 2024. Knowledge cutoff: solar-mini Sep 2024, DeepSeek-R1 Jul 2024, Pixtral 12B Sep 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.
