This works: $ZAI_ANTHROPIC_BASE_URL=xxx $ZAI_ANTHROPIC_AUTH_TOKEN=xxx

  alias "claude-zai"="ANTHROPIC_BASE_URL=$ZAI_ANTHROPIC_BASE_URL ANTHROPIC_AUTH_TOKEN=$ZAI_ANTHROPIC_AUTH_TOKEN claude"

Then you can run `claude`, hit your limit, exit the session and `claude-zai -c` to continue (with context reset, of course).

Someone gave me that command a while back.
