- Use provider model ID "holo4-27b", not the LLMReference slug "holo-4-27b".
- 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.

About Holo4-27B
Holo4-27B is H Company's 27B dense vision-language model for computer-use agents, released September 28, 2026 as the larger of the two Holo4 models. Built on Qwen3.8-27B, it reads screenshots and text and acts by clicking and typing, writing and running its own code, or calling MCP and API tools, across web, desktop and Android. It has a 262,144-token context, thinking on by default with low, medium and xhigh reasoning effort, and native function calling. Open weights in BF16, FP8, NVFP4 and GGUF are released under CC BY-NC 4.0 for non-commercial use; commercial use is through the H Models API (holo4-27b).
