Z.ai: GLM 4.6 (exacto)
Analysis Summary
GLM 4.6 (exacto) is a variant of Z.ai's GLM 4.6 model, listed with tool use and function calling support and a 204K context window. No independent benchmark data is available for this specific variant, so its performance relative to the base GLM 4.6 cannot be confirmed.
Without benchmark evidence, it must be treated as an unverified model regardless of the base model's scores. Businesses should use the benchmarked GLM 4.6 if they require verified performance, or wait for this variant's own evaluation data before adopting it in production.
Pricing is nearly identical to GLM 4.6 at $0.44 input and $1.76 output. The regional penalty also applies. There is no clear reason to prefer this variant over the benchmarked base model until independent data is available.
