ComfyUI-LoRA-Optimizer

BuildAutoTunerPythonEvaluator

Builds a Python evaluator spec for LoRA AutoTuner so candidate ranking can incorporate prompt/reference scoring from external code.

LoRA Optimizer · 0 inputs · 5 parameters · 1 output

key_a

Compact description unavailable for this node.

LoadTunerData

Loads saved AutoTuner results from disk so they can be fed to Merge Selector without re-running the tuner.

LoRA Optimizer · 0 inputs · 1 parameter · 4 outputs

LoRAAutoTuner

Automatically sweeps all merge parameters and ranks

LoRA Optimizer · 4 inputs · 21 parameters · 6 outputs

LoRAAutoTunerSettings

Runs an automatic parameter sweep to find the best merge settings for your LoRA stack.

LoRA Optimizer · 2 inputs · 11 parameters · 1 output

LoRACombinationGenerator

Generates all LoRA combinations for AutoTuner dataset

LoRA Optimizer · 0 inputs · 6 parameters · 2 outputs

LoRACompatibilityAnalyzer

Analyzes LoRA compatibility and suggests merge groups. No merge is performed.

LoRA Optimizer · 3 inputs · 2 parameters · 2 outputs

LoRAConflictEditor

Analyzes LoRA conflicts and lets you control per-LoRA conflict modes and merge strategy. Connect between a LoRA Stack and the LoRA Optimizer.

LoRA Optimizer · 3 outputs

LoRAEstimator

Predict a merge config via k-NN retrieval over the HF community cache. Runs Phase 1 (shared with AutoTuner) to build a combo feature vector, retrieves similar past merges, aggregates their winning configs, and emits a ``tuner_data`` struct the LoRA Optimizer consumes via ``settings_source=from_tuner_data`` — skipping Phase 2 grid search.

LoRA/Optimization · 3 inputs · 3 parameters · 2 outputs

LoRAExtractFromModel

Extracts a LoRA that was baked into a finetuned model by comparing it against

LoRA Optimizer · 5 inputs · 4 parameters · 2 outputs

LoRAInlineChainOptions

Per-LoRA options for the LoRA Optimizer (Inline Chain) node.

LoRA Optimizer · 1 output

LoRAMergeFormula

Attaches a merge formula to the LoRA stack to control hierarchical merge order

LoRA Optimizer · 1 input · 1 parameter · 1 output

LoRAMergeSelector

Applies a specific merge configuration from LoRA AutoTuner results.

LoRA Optimizer · 4 inputs · 6 parameters · 4 outputs

LoRAMergeSettings

Shared settings that apply to both Optimizer and AutoTuner modes.

LoRA Optimizer · 0 inputs · 11 parameters · 1 output

LoRAMetadataReader

Reads embedded metadata (prompt, description, merge info) from LoRAs in the stack. The stack passes through unchanged.

LoRA Optimizer · 1 input · 0 parameters · 4 outputs

LoRAOptimizer

Auto-analyzes a LoRA stack and selects heuristic merge strategies per weight group. Outputs merged model + analysis report. Best for style/character LoRAs — apply edit, distillation (LCM/Turbo/Hyper), or DPO LoRAs via a standard Load LoRA node instead.

LoRA Optimizer · 5 inputs · 20 parameters · 5 outputs

LoRAOptimizerInline

Drop-in filter: place after a chain of regular Load LoRA nodes.

4 inputs · 2 parameters

LoRAOptimizerSettings

Advanced settings for fine-tuning how LoRAs are merged.

LoRA Optimizer · 2 inputs · 10 parameters · 1 output

LoRAOptimizerSimple

Simplified LoRA Optimizer — merges a LoRA stack with good defaults.

5 inputs · 2 parameters

LoRAStack

Adds a LoRA to the stack for use with LoRA Optimizer

LoRA Optimizer · 1 output

LoRAStackDynamic

Dynamic LoRA stacker with adjustable slot count and optional per-LoRA CLIP strength

LoRA Optimizer · 1 output

MergedLoRAToHook

Wraps merged LoRA patches as a conditioning hook (HOOKS).

LoRA Optimizer · 2 inputs · 0 parameters · 1 output

MergedLoRAToWanVideo

Bridges merged LoRA patches from the LoRA Optimizer to a WanVideo wrapper model.

LoRA Optimizer · 2 inputs · 0 parameters · 1 output

per_prefix

Compact description unavailable for this node.

SaveMergedLoRA

Saves merged LoRA data as a standalone .safetensors file that can be loaded by any standard LoRA loader.

LoRA Optimizer · 1 input · 6 parameters · 1 output

SaveTunerData

Saves AutoTuner results to a .tuner file so they can be reloaded later without re-running the tuner.

LoRA Optimizer · 1 input · 5 parameters · 1 output

WanVideoLoRAOptimizer

WanVideo LoRA Optimizer — merges multiple WanVideo LoRAs using
