Add robust device capability detection for bfloat16, replacing hardcoded
dtype with runtime checks that fallback to float16/float32 on unsupported
hardware. This prevents runtime failures on GPUs and CPUs without bfloat16.
Key changes:
- Add TorchDevice.choose_bfloat16_safe_dtype() helper for safe dtype selection
- Fix LoRA device mismatch in layer_patcher.py (add device= to .to() call)
- Replace all assert statements with descriptive exceptions (TypeError/ValueError)
- Add hidden_states bounds check and apply_chat_template fallback in text encoder
- Add GGUF QKV tensor validation (divisible by 3 check)
- Fix CPU noise generation to use float32 for compatibility
- Remove verbose debug logging from LoRA conversion utils
Add support for saving and recalling Z-Image component models (VAE and
Qwen3 Encoder) in image metadata.
Backend:
- Add qwen3_encoder field to CoreMetadataInvocation (version 2.1.0)
Frontend:
- Add vae and qwen3_encoder to Z-Image graph metadata
- Add Qwen3EncoderModel metadata handler for recall
- Add ZImageVAEModel metadata handler (uses zImageVaeModelSelected
instead of vaeSelected to set Z-Image-specific VAE state)
- Add qwen3Encoder translation key
This enables "Recall Parameters" / "Remix Image" to restore the VAE
and Qwen3 Encoder settings used for Z-Image generations.
Add support for loading Z-Image transformer and Qwen3 encoder models
from single-file safetensors format (in addition to existing diffusers
directory format).
Changes:
- Add Main_Checkpoint_ZImage_Config and Main_GGUF_ZImage_Config for
single-file Z-Image transformer models
- Add Qwen3Encoder_Checkpoint_Config for single-file Qwen3 text encoder
- Add ZImageCheckpointModel and ZImageGGUFCheckpointModel loaders with
automatic key conversion from original to diffusers format
- Add Qwen3EncoderCheckpointLoader using Qwen3ForCausalLM with fast
loading via init_empty_weights and proper weight tying for lm_head
- Update z_image_denoise to accept Checkpoint format models
Add comprehensive support for GGUF quantized Z-Image models and improve component flexibility:
Backend:
- New Main_GGUF_ZImage_Config for GGUF quantized Z-Image transformers
- Z-Image key detection (_has_z_image_keys) to identify S3-DiT models
- GGUF quantization detection and sidecar LoRA patching for quantized models
- Qwen3Encoder_Qwen3Encoder_Config for standalone Qwen3 encoder models
Model Loader:
- Split Z-Image model
Move Flux layer structure check before metadata check to prevent misidentifying Z-Image LoRAs (which use `diffusion_model.layers.X`) as Flux AI Toolkit format. Flux models use `double_blocks` and `single_blocks` patterns which are now checked first regardless of metadata presence.
* feat: Add bulk delete functionality for models, LoRAs, and embeddings
Implements a comprehensive bulk deletion feature for the model manager that allows users to select and delete multiple models, LoRAs, and embeddings at once.
Key changes:
Frontend:
- Add multi-selection state management to modelManagerV2 slice
- Update ModelListItem to support Ctrl/Cmd+Click multi-selection with checkboxes
- Create ModelListHeader component showing selection count and bulk actions
- Create BulkDeleteModelsModal for confirming bulk deletions
- Integrate bulk delete UI into ModelList with proper error handling
- Add API mutation for bulk delete operations
Backend:
- Add POST /api/v2/models/i/bulk_delete endpoint
- Implement BulkDeleteModelsRequest and BulkDeleteModelsResponse schemas
- Handle partial failures with detailed error reporting
- Return lists of successfully deleted and failed models
This feature significantly improves user experience when managing large model libraries, especially when restructuring model storage locations.
Fixes issue where users had to delete models individually after moving model files to new storage locations.
* fix: prevent model list header from scrolling with content
* fix: improve error handling in bulk model deletion
- Added proper error serialization using serialize-error for better error logging
- Explicitly defined BulkDeleteModelsResponse type instead of relying on generated schema reference
* refactor: improve code organization in ModelList components
- Reordered imports to follow conventional grouping (external, internal, then third-party utilities)
- Added type assertion for error serialization to satisfy TypeScript
- Extracted inline event handler into named callback function for better readability
* refactor: consolidate Button component props to single line
* feat(ui): enhance model manager bulk selection with select-all and actions menu
- Added select-all checkbox in navigation header with indeterminate state support
- Replaced single delete button with actions dropdown menu for future extensibility
- Made checkboxes always visible instead of conditionally showing on selection
- Moved model filtering logic to ModelListNavigation for select-all functionality
- Improved UX by showing selection state for filtered models only
* fix the wrong path seperater from my windows system

Add comprehensive support for Z-Image-Turbo (S3-DiT) models including:
Backend:
- New BaseModelType.ZImage in taxonomy
- Z-Image model config classes (ZImageTransformerConfig, Qwen3TextEncoderConfig)
- Model loader for Z-Image transformer and Qwen3 text encoder
- Z-Image conditioning data structures
- Step callback support for Z-Image with FLUX latent RGB factors
Invocations:
- z_image_model_loader: Load Z-Image transformer and Qwen3 encoder
- z_image_text_encoder: Encode prompts using Qwen3 with chat template
- z_image_denoise: Flow matching denoising with time-shifted sigmas
- z_image_image_to_latents: Encode images to 16-channel latents
- z_image_latents_to_image: Decode latents using FLUX VAE
Frontend:
- Z-Image graph builder for text-to-image generation
- Model picker and validation updates for z-image base type
- CFG scale now allows 0 (required for Z-Image-Turbo)
- Clip skip disabled for Z-Image (uses Qwen3, not CLIP)
- Optimal dimension settings for Z-Image (1024x1024)
Technical details:
- Uses Qwen3 text encoder (not CLIP/T5)
- 16 latent channels with FLUX-compatible VAE
- Flow matching scheduler with dynamic time shift
- 8 inference steps recommended for Turbo variant
- bfloat16 inference dtype

* Wrap GGUF loader for context managed close()
Wrap gguf.GGUFReader and then use a context manager to load memory-mapped GGUF files, so that they will automatically close properly when no longer needed. Should prevent the 'file in use in another process' errors on Windows.
* Additional check for cached state_dict
Additional check for cached state_dict as path is now optional - should solve model manager 'missing' this and the resultant memory errors.

## Summary
This fixes a bug in which private directory paths on the host could be
leaked to the user interface. The error occurs during the `scan_folders`
operation when a subdirectory is not accessible. The UI shows a
permission denied error message, followed by the path of the offending
directory. This patch limits the error message to the error type only
and does not give further details.
## Related Issues / Discussions
This bug was reported in a private DM on the Discord server.
## QA Instructions
Before applying this PR, go to ***Model Manager -> Add Model -> Scan
Folder*** and enter the path of a directory that has subdirectories that
the backend should not have access to, for example `/etc`. Press the
***Scan Folder*** button. You will see a Permission Denied error message
that gives away the path of the first inaccesislbe subdirectory.
After applying this PR, you will see just the Permission Denied error
without details.
## Merge Plan
Merge when approved.
