Which should you choose?
Which is better: Claude Haiku 3 or Sonar?
Claude Haiku 3 is the better all-round choice, scoring 56/100 against 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 or Sonar?
Claude Haiku 3 is cheaper at $0.25 input / $1.25 output per million tokens (median across 2 API providers). 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 $1.00 for Sonar (2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Claude Haiku 3 has an ECI of 118.4 and Sonar has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Claude Haiku 3 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. Maximum output per response: Claude Haiku 3 up to 4,096, Sonar up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Claude Haiku 3 accepts text, images and PDFs; Sonar accepts text. Claude Haiku 3 handles the widest range of inputs.
Are any of these open source?
No. Claude Haiku 3 and Sonar are proprietary and only available through APIs and apps.
Which is newer?
Claude Haiku 3 is the newest, released Mar 13, 2024. Sonar came out Jan 1, 2024. Knowledge cutoff: Claude Haiku 3 Aug 31, 2023, 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.
