GLM-5.1 vs GLM-5V-Turbo

This comparison does not currently contain a protocol-matched coding benchmark for both GLM-5.1 and GLM-5V-Turbo, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only GLM-5.1 has a directly sourced input price: $1.05 per million tokens. Only GLM-5.1 has a directly sourced output price: $3.50 per million tokens.

GLM-5.1 has the larger sourced context window. GLM-5.1 supports 202,752 and GLM-5V-Turbo supports 200,000.

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

GLM-5.1 is the only model in this pair currently marked as self-hostable. GLM-5.1 is open weight; GLM-5V-Turbo is not marked open weight.

GLM-5.1 is not documented with image input; GLM-5V-Turbo is documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. GLM-5.1 is — and GLM-5V-Turbo is 131,072.

GLM-5.1: reasoning and tool calling. GLM-5V-Turbo: reasoning, tool calling, and image input. Feature support does not establish relative quality.

GLM-5.1 has 2 sourced provider routes; GLM-5V-Turbo has 1, so GLM-5.1 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.
