Know the exact model.

The canonical record is zai-org:glm-5.2. Capabilities and context limits reflect source observations; the limits of a particular inference endpoint may differ.

Inclusion in the radar does not mean this model is served by Flonno. For the model currently available through our API, see Qwen3.8 Flash 27B and API pricing.

Evaluate it for your workflow.

Pin the artifact and inference configuration. Use representative inputs with a written answer rubric, then record accepted results, errors, complete request time and token usage. Keep output budgets and concurrency explicit.

Benchmark results apply to their recorded version and method. They do not transfer automatically to a different runtime or a quantized derivative.
