OpenClaw + Terraphim LLM Proxy: OpenAI, Z.ai GLM-5, and MiniMax M2.5

If you want OpenClaw to use multiple providers through a single endpoint, with Terraphim AI intelligent LLM proxy : OpenAI Codex ( gpt-5.2 ) Z.ai ( glm-5 ) MiniMax ( MiniMax-M2.5 ) intelligent keyword routing automatic fallback when a provider goes down This guide reflects a real build-in-public rollout on terraphim-llm-proxy , including production debugging, fallback drills, and routing verification. Why this setup Most agent stacks fail at provider outages and model sprawl. A single proxy with explicit route chains keeps clients stable while you switch providers underneath. Proxy config pattern Use route chains in /etc/terraphim-llm-proxy/config.toml : [router] default = "openai-codex,gpt-5.2-codex|zai,glm-5" think = "openai-codex,gpt-5.2|minimax,MiniMax-M2.5|zai,glm-5" long_context = "openai-codex,gpt-5.2|zai,glm-5" web_search = "openai-codex,gpt-5.2|zai,glm-5" strategy = "fill_first" [[providers]] name = "openai-codex" api_base_url = "https://api.openai.com/v1" api_key = "oauth-tok
