- GLM (Z.ai) models answer on
POST https://api.rodiumai.io/v1/chat/completions(OpenAI format), served through RodiumAi's cloud upstreams. max_tokensandmax_completion_tokensare both accepted. Leave generous room for thinking models: a few thousand tokens.- Thinking models can return their reasoning separately. Streaming deltas may include
reasoning_contentbefore the finalcontent. - OpenAI-only fields such as
n,seedorlogit_biasare ignored. Streaming, tools and JSON mode depend on the Capabilities section.
