Cursor

Open Cursor Settings → Models → API Keys → enable the "OpenAI API Key" toggle → enter your key → an "Override OpenAI Base URL" field will appear:

Override OpenAI Base URL:  https://imbutus.com
API Key:                   <your-api-key>

Then add each model ID below to the Models list in Cursor settings:

huihui-ai/Huihui-Qwen3.5-9B-Claude-4.6-Opus-abliterated
huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated
huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated
huihui-ai/Huihui-Qwen3-Coder-Next-abliterated

Note: Cursor defaults custom models to a 1M token context window regardless of the actual model limit. If you hit API errors, reduce the number of files in context manually. Model context windows:
