Sonar vs GLM 5.2

This comparison does not currently contain a protocol-matched coding benchmark for both Sonar and GLM 5.2, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Sonar is $1.00 and GLM 5.2 is $0.75 per million tokens, so GLM 5.2 is cheaper on this metric. Sonar is $1.00 and GLM 5.2 is $2.40 per million tokens, so Sonar is cheaper on this metric.

GLM 5.2 has the larger sourced context window. Sonar supports 128K and GLM 5.2 supports 1,049K.

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

GLM 5.2 is the only model in this pair currently marked as self-hostable. Sonar is not marked open weight; GLM 5.2 is open weight.

Sonar is not documented with image input; GLM 5.2 is not documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. Sonar is — and GLM 5.2 is —.

Sonar: none of these features are definitively sourced. GLM 5.2: reasoning and tool calling. Feature support does not establish relative quality.

Sonar has 2 sourced provider routes; GLM 5.2 has 5, so GLM 5.2 has broader tracked availability.

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
