Z.ai: GLM 5 Turbo

GLM 5 Turbo, from Z.ai, is a text-in, text-out model with a 262,144-token context window and a 131,072-token completion limit, making it capable of handling long documents or extended multi-turn sessions. It supports tool use and reasoning, which covers agentic and chain-of-thought workflows. Structured output support is unconfirmed, so developers who depend on reliable JSON schemas should verify that independently before committing. On the comparison front, benchmark coverage is thin, with a blended score of 62.9 drawn from a single benchmark, so treat performance claims as preliminary rather than settled. Pricing sits at $1.20 per million input tokens and $4.00 per million output tokens, which is mid-range. Teams drawn to its large context or reasoning support should weigh those features against the limited benchmark evidence and confirm structured output behavior before production use.
