Which should you choose?
Which is better: Claude Haiku 3, Mixtral 8x7B or Sonar?
Claude Haiku 3 is the better all-round choice, scoring 56/100 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, Claude Haiku 3, Mixtral 8x7B or Sonar?
Claude Haiku 3 is cheaper at $0.25 input / $1.25 output per million tokens (median across 2 API providers). 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 $0.50 per million tokens for Claude Haiku 3 versus $0.70 for Mixtral 8x7B (1.4× as much) and $1.00 for Sonar (2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Claude Haiku 3 has an ECI of 118.4, Mixtral 8x7B has an ECI of 118.5 and Sonar has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Claude Haiku 3, Mixtral 8x7B 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?
Claude Haiku 3 has the largest context window at 200,000 tokens, against 128,000 for Sonar and 32,000 for Mixtral 8x7B. Maximum output per response: Claude Haiku 3 up to 4,096, Mixtral 8x7B up to 32,000, Sonar up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Claude Haiku 3 accepts text, images and PDFs; Mixtral 8x7B accepts text; Sonar accepts text. Claude Haiku 3 handles the widest range of inputs.
Are any of these open source?
Mixtral 8x7B publishes its weights and can be self-hosted; Claude Haiku 3 and Sonar is proprietary.
Which is newer?
Claude Haiku 3 is the newest, released Mar 13, 2024. Sonar came out Jan 1, 2024; Mixtral 8x7B came out Dec 11, 2023. Knowledge cutoff: Claude Haiku 3 Aug 31, 2023, Mixtral 8x7B Jan 2024, Sonar Sep 1, 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.
