Workload guidance

Which model should you choose?

Consider GPT-5.4 if you need larger context or larger maximum output. Consider GLM-4.6V if you need a lower listed input rate or a lower listed output rate. GLM-4.6V offers downloadable weights; GPT-5.4 is listed as a proprietary model. Compare licence terms and operating costs before choosing a deployment. Test both on the same representative examples and judge the output against your acceptance criteria. Include tool failures, retries and the time to a completed task.
