GLM-5-Turbo Shows Low Tool Call Error Rate in User Testing
The z-ai/glm-5-turbo model is showing promising performance for tool calling applications according to user testing shared on r/LocalLLaMA.
Benchmark Results
Testing indicates the model achieves a very low tool call error rate of 0.57% on average. This represents a significant improvement over the standard GLM-5 model, which shows approximately 3% error rate - making GLM-5-turbo about 6 times more accurate for tool calling tasks.
When compared to other providers' models:
- Anthropic models range from 0.38% to 0.93% with 0.67% average
- Amazon Bedrock models range from 1.48% to 1.76% with 1.63% average
- Google Vertex models range from 0.99% to 2.62% with 1.93% average
Practical Application
A user tested GLM-5-turbo with a novel CLI tool for writing fantasy novels and reported substantial improvements over previous models. With the standard GLM-5, the tool was "a bit flaky when it came to something none english, and randomly dont now what command to use correctly compare to the user request."
Using GLM-5-turbo (Max plan), the user successfully wrote 97,000 words with "no flaky, no em-dash, connected chapters and tool calls has been almost done right." The model specifically supports OpenClaw well according to the source.
Usage Considerations
The source suggests GLM-5-turbo may be suitable for side projects requiring coding assistance, but cautions that for production projects requiring more stable factors, "it feel like not a right choices." The user also mentioned considering using NemoClaw with GLM-5-turbo on a homelab setup rather than OpenClaw.
Initial usage data on Openrouter shows good numbers for the first 100B tokens, though specific metrics weren't provided in the source.
