From 694e2f04273b6cb5de87c96a86e3a24f98228e19 Mon Sep 17 00:00:00 2001 From: CalamitousFelicitousness Date: Mon, 19 Jan 2026 01:24:40 +0000 Subject: [PATCH 001/122] fix(settings): support aliases in metadata skip params The "Restore from metadata: skip params" setting previously required exact metadata parameter names (e.g., "Batch-2" instead of "batch_size"). This was confusing because metadata names differ from Python variables and UI labels. Changes: - Auto-populate param_aliases from component labels and elem_ids - Expand user input with aliases in should_skip() - Support normalized names so "Batch" skips both "Batch-1" and "Batch-2" Users can now enter any of these formats (case-insensitive): - Python variable names: batch_size, cfg_scale, clip_skip - UI labels: Batch size, CFG scale, Clip skip - Metadata names: Batch-2, CFG scale, Clip skip - Normalized names: Batch (skips both Batch-1 and Batch-2) --- modules/generation_parameters_copypaste.py | 47 +++++++++++++++++++++- 1 file changed, 45 insertions(+), 2 deletions(-) diff --git a/modules/generation_parameters_copypaste.py b/modules/generation_parameters_copypaste.py index 9662024a3..4a53c74e9 100644 --- a/modules/generation_parameters_copypaste.py +++ b/modules/generation_parameters_copypaste.py @@ -17,6 +17,10 @@ debug('Trace: PASTE') parse_generation_parameters = parse #

+0000 Subject: [PATCH 003/122] feat(caption): integrate DeepBooru into unified Booru Tagger UI Add DeepBooru as a model option alongside WD14 models in the Booru Tags tab, with dynamic UI that disables inapplicable controls. Changes: - Create modules/interrogate/tagger.py as unified adapter module - Add batch, load/unload, get_models functions to deepbooru.py - Update ui_caption.py to use unified tagger interface - Consolidate shared tagger settings in shared.py - Add implementation plan for future settings consolidation UI behavior: - Model dropdown shows DeepBooru + all WD14 models - Character threshold and include rating disabled for DeepBooru - All controls re-enable when WD14 model selected --- modules/interrogate/deepbooru.py | 209 +++++++++++++++++++++++++++++-- modules/interrogate/tagger.py | 79

CalamitousFelicitousness Date: Wed, 21 Jan 2026 02:45:12 +0000 Subject: [PATCH 005/122] refactor(caption): unify tagger settings and reorganize Caption Tab UI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidate WD14 and DeepBooru tagger settings into unified options: - Merge wd14_general_threshold + deepbooru_score_threshold → tagger_threshold - Merge wd14_include_rating + deepbooru_include_rating → tagger_include_rating - Rename interrogate_score → tagger_show_scores - Rename tagger_escape → tagger_escape_brackets - Rename CLiP → OpenCLiP in caption type choices UI reorganization: - Add Interrogate tab to Caption Tab with default caption type selector - Move interrogate_offload to Model Offloading section as "Offload caption models" - Hide Interrogate settings section (all settings now in Caption Tab UI) - Update locale_en.json for OpenCLiP naming Code improvements: - DeepBooru tag_multi() now accepts same parameters as WD14 for unified interface - Fix setting references in interrogate.py for consolidated settings - Add comprehensive tagger test suite (cli/test-tagger.py) --- cli/test-tagger.py | 849

import gc stats = {} From 6b10f0df4febdaba5aa1fc5324de1cf84ced45ac Mon Sep 17 00:00:00 2001 From: CalamitousFelicitousness Date: Wed, 21 Jan 2026 09:46:08 +0000 Subject: [PATCH 007/122] refactor(caption): address PR review feedback Rename WD14 module and settings to WaifuDiffusion: - Rename wd14.py to waifudiffusion.py - Rename WD14Tagger class to WaifuDiffusionTagger - Rename WD14_MODELS constant to WAIFUDIFFUSION_MODELS - Rename settings: wd14_model -> waifudiffusion_model, wd14_character_threshold -> waifudiffusion_character_threshold - Update all log messages from "WD14" to "WaifuDiffusion" Code quality improvements: - Simplify threshold parameter defaulting using `or` operator - Extract save_output logic into _save_tags_to_file() helper with isolated error handling to prevent single file failures from impacting entire batch -
