GoKawiilZhipu's GLM-5.3-Flash scores 57 on Intelligence Index at low token pricing
GLM-5.3-Flash is a text-only model with a 400k token context window that scored 57 on the Artificial Analysis Intelligence Index, far above the comparable median of 18. It is priced at $0.15 per 1M input tokens and $0.50 per 1M output tokens, both below the median rates for similar models, with the full benchmark run costing $138.02.
GoKawiil's interpretation of the reporting above, not reported fact.
The result signals that strong reasoning performance is increasingly available at budget pricing, intensifying competition among model providers on cost-efficiency rather than just raw capability. However, the model's verbosity, generating far more tokens than average during evaluation, could offset its price advantage in real-world usage where output volume drives cost.
- GLM-5.3-Flash scored 57 on the Intelligence Index, well above the 18 median for similar-cost models
- Its pricing ($0.15/$0.50 per 1M tokens) undercuts the median rates for comparable models
- The model is notably verbose, using over twice the median token count during evaluation
