Readme
ComfyUI LMStudio Nodes (Unofficial)
Small ComfyUI custom nodes to connect to a remote LMStudio server through OpenAI-compatible API (/v1).
Nodes
-
LMStudio - Connect
- Connect to a remote LMStudio URL
- Pick the model from a dropdown populated by Refresh Models
- Test connectivity to the server
- Thinking / Reasoning control —
auto/on/off:auto— defer to the model, but force reasoning on for families that stay silent by default (Gemma). Qwen3-style models already think by default.on— force reasoning on (enable_thinking: true).off— suppress reasoning so the model answers directly and doesn't burn its token budget on a hidden<think>trace.
- Advanced: API token, Tooling / MCP toggle, max tokens, temperature, timeout
-
LMStudio - Text Gen
- System prompt + user prompt
- Text generation through the shared connection
<think>...</think>blocks are stripped from response output
-
LMStudio - Image To Text
- System prompt + user prompt + image input
- Image description / caption style generation
<think>...</think>blocks are stripped from response output
