Sonar Reasoning Pro vs GLM 5

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

Sonar Reasoning Pro is $2.00 and GLM 5 is $0.60 per million tokens, so GLM 5 is cheaper on this metric. Sonar Reasoning Pro is $8.00 and GLM 5 is $1.92 per million tokens, so GLM 5 is cheaper on this metric.

GLM 5 has the larger sourced context window. Sonar Reasoning Pro supports 128K and GLM 5 supports 203K.

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

GLM 5 is the only model in this pair currently marked as self-hostable. Sonar Reasoning Pro is not marked open weight; GLM 5 is open weight.

Sonar Reasoning Pro is not documented with image input; GLM 5 is not documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. Sonar Reasoning Pro is — and GLM 5 is —.

Sonar Reasoning Pro: reasoning. GLM 5: reasoning and tool calling. Feature support does not establish relative quality.

Sonar Reasoning Pro has 2 sourced provider routes; GLM 5 has 4, so GLM 5 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.
