Gotchas

  • Use provider model ID "holo3-1-35b-a3b", not the LLMReference slug "holo-3-1-35b-a3b".
  • Use H Company API model IDs from provider rows, such as holo3-1-35b-a3b or holo3-122b-a10b. These differ from LLMReference display slugs.
  • The examples expect HAI_API_KEY; rename it only if your application config maps the new variable.
