Claude Code now talks to the raw /anthropic path of the Eltex proxy,
which forwards requests byte-for-byte to the Z.ai Anthropic endpoint,
the same one ai-glm uses directly:
- images work through Z.ai's server-side analyze_image (Read png ->
server_tool_use analyze_image -> correct answer, same as ai-glm);
the regular /v1/messages route converts to the OpenAI endpoint,
where Z.ai rejects images with 400;
- effort reaches Z.ai: low has no thinking, then medium < high < max;
- prompt cache: ~99% of input is a cache read from the second turn,
same as ai-glm.
The key check and model pick still use the proxy root /v1/models.
The model is glm-5.3 in every picker slot with [1m] for the 1M
window; the anth-glm-5.3 / zai-glm-5.3 / flash names are gone.
Effort stays max by default via CLI --effort.
Checked on 20.10 on llm-t2.eltex.loc:4000; admins are moving that
config to llm.eltex.loc:4000, which stays the default URL.
