Qwen Plus is our pick
Qwen Plus is the better all-round choice, scoring 53/100 against Mixtral 8x7B (36) and Sonar (30). It leads on price, inputs & features 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 should you choose?
Which is better: Mixtral 8x7B, Qwen Plus or Sonar?
Qwen Plus is the better all-round choice, scoring 53/100 against Mixtral 8x7B (36) and Sonar (30). It leads on price, inputs & features 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, Mixtral 8x7B, Qwen Plus or Sonar?
Qwen Plus is cheaper at $0.40 input / $1.20 output per million tokens (official Alibaba API price). Mixtral 8x7B costs $0.70 input / $0.70 output per million tokens (official Mistral API price); Sonar costs $1.00 input / $1.00 output per million tokens (official Perplexity API price). At a typical mix of three input tokens to one output token, that is $0.60 per million tokens for Qwen Plus versus $0.70 for Mixtral 8x7B (1.2× as much) and $1.00 for Sonar (1.7× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Mixtral 8x7B has an ECI of 118.5, Qwen Plus has not been scored yet and Sonar has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Mixtral 8x7B, Qwen Plus and Sonar yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar does not support tool calling, which most coding agents need.
Which has the bigger context window?
Qwen Plus has the largest context window at 1,000,000 tokens, against 128,000 for Sonar and 32,000 for Mixtral 8x7B. Maximum output per response: Mixtral 8x7B up to 32,000, Qwen Plus up to 32,768, Sonar up to 4,096 tokens.

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.
