Z.ai: GLM 5
The Z.ai: GLM 5 model is designed for text-based inputs and supports tools, reasoning, but does not output structured data. It can handle long context lengths of up to 204800 tokens and generate completions up to 128000 tokens. Considering the price point, this model may be a viable option for those with budgets in excess of $0.6 per million input tokens. The model's blended benchmark score is 67.3 across two independent benchmarks; however, its performance on specific tasks such as AI Index and EQBench remains unclear due to limited coverage.
