Qwen3.5 397B A17B vs Sonar

This comparison does not currently contain a protocol-matched coding benchmark for both Qwen3.5 397B A17B and Sonar, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Qwen3.5 397B A17B is $0.45 and Sonar is $1.00 per million tokens, so Qwen3.5 397B A17B is cheaper on this metric. Qwen3.5 397B A17B is $3.00 and Sonar is $1.00 per million tokens, so Sonar is cheaper on this metric.

Qwen3.5 397B A17B has the larger sourced context window. Qwen3.5 397B A17B supports 262K and Sonar supports 128K.

There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.

Qwen3.5 397B A17B is the only model in this pair currently marked as self-hostable. Qwen3.5 397B A17B is open weight; Sonar is not marked open weight.

Qwen3.5 397B A17B is documented with image input; Sonar is not documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. Qwen3.5 397B A17B is — and Sonar is —.

Qwen3.5 397B A17B: reasoning, tool calling, and image input. Sonar: none of these features are definitively sourced. Feature support does not establish relative quality.
