Use cases

  • Agentic coding and tool-using assistants.
  • Bilingual Chinese and English applications.
  • Long-form writing and summarisation.
  • Cost-sensitive chat at volume (Flash variants).

Notes

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