01 — Verdict

Too close to call

It is close. Our weighted score puts them within 1 points (Qwen Plus 53/100, Qwen2.5-VL 7B Instruct 51/100, Sonar 30/100), so choose by what matters most for your work: Qwen2.5-VL 7B Instruct on price and Qwen Plus for long inputs. 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.

04 — Questions

Which should you choose?

Which is better: Qwen Plus, Qwen2.5-VL 7B Instruct or Sonar?

It is close. Our weighted score puts them within 1 points (Qwen Plus 53/100, Qwen2.5-VL 7B Instruct 51/100, Sonar 30/100), so choose by what matters most for your work: Qwen2.5-VL 7B Instruct on price and Qwen Plus for long inputs. 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, Qwen Plus, Qwen2.5-VL 7B Instruct or Sonar?

Qwen2.5-VL 7B Instruct is cheaper at $0.35 input / $1.05 output per million tokens (official Alibaba API price). Qwen Plus costs $0.40 input / $1.20 output per million tokens (official Alibaba 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 $0.525 per million tokens for Qwen2.5-VL 7B Instruct versus $0.60 for Qwen Plus (1.1× as much) and $1.00 for Sonar (1.9× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Qwen Plus has not been scored yet, Qwen2.5-VL 7B Instruct 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 Qwen Plus, Qwen2.5-VL 7B Instruct 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 131,072 for Qwen2.5-VL 7B Instruct and 128,000 for Sonar. Maximum output per response: Qwen Plus up to 32,768, Qwen2.5-VL 7B Instruct up to 8,192, Sonar up to 4,096 tokens.

Which can read images, PDFs, audio or video?

Qwen Plus accepts text; Qwen2.5-VL 7B Instruct accepts text and images; Sonar accepts text. Qwen2.5-VL 7B Instruct handles the widest range of inputs.

Are any of these open source?

Qwen2.5-VL 7B Instruct publishes its weights and can be self-hosted; Qwen Plus and Sonar is proprietary.

Which is newer?

Qwen2.5-VL 7B Instruct is the newest, released Sep 2024. Qwen Plus came out Jan 25, 2024; Sonar came out Jan 1, 2024. Knowledge cutoff: Qwen Plus Apr 2024, Qwen2.5-VL 7B Instruct Apr 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.
