How is this better than hardcoding prompt keywords?

Decisions come from a typed judgment over the actual text with probabilities, so routing follows meaning rather than brittle substring matches, with confidence available for gating.

How do I pick between LoRA-by-name and LoRA-by-branch?

Use by-name when one loader can take the winning filename string, and by-branch with the choice switch when each option needs its own loader chain behind the winning index.

What does the confidence output actually buy me?

A threshold switch between the chosen branch and a safe default, so low-confidence judgments fall back instead of driving the workflow blindly.

Noul answers show confidence 1.0 — is that a bug?

No, that is the documented behavior: noul outputs carry no separate confidence value, so design gates around choice or score outputs when you need one.

How do I install these nodes and what do they require?

Clone the repo into ComfyUI/custom_nodes, then install it into ComfyUI's environment with uv pip install --no-deps -e custom_nodes/systemone-nodes. The only dependency is requests, which ComfyUI already ships.

What format do the question criteria take for each type?

A choice takes one key: description per line. A score takes one level per line, lowest first, with 2 to 10 levels. A noul takes optional true: and false: lines; without them it is a bare yes/no probability.

How does a workflow ask several questions and branch on one answer?

The SystemOne node sends the state plus every connected question in one request to server_url, default http://localhost:8765/v1/systemone. The Answer node then picks one answer by name and exposes choice, index, value, confidence and probabilities for wiring into switches.

Systemone Nodes

ComfyUI custom nodes that send text plus typed SystemOne questions in one request and branch the image workflow on the answers, such as picking a LoRA from the prompt.

About this project

ComfyUI nodes that ask a SystemOne server typed questions about some text and branch the workflow on the answers — e.g. pick a LoRA from the prompt. Clone into ComfyUI/customnodes/, then install the package into ComfyUI's environment: cd ComfyUI && uv pip install --no-deps -e customnodes/systemone-nodes. Requires requests (already a ComfyUI dependency). For a hosted server, set TYPESAFEAPIKEY in ComfyUI's environment. It is sent as a Bearer token and never stored in workflows.

Highlights

Question node defines one noul, choice, or score question with criteria lines; the sender node batches state and all connected questions.
Answer node exposes choice text, index, float value, confidence, and probabilities for wiring into downstream nodes.
Threshold and choice switches run only the selected branch, enabling confidence gates and multi-LoRA fan-out.
Installs into custom_nodes with only requests beside ComfyUI deps; a hosted server takes a Bearer key never stored in workflows.

Watch out

Community ComfyUI nodes; routing quality follows the model and your criteria text. Copy reviewed against the repository README on 2026-10-04, not from running it.
