This commit introduces a new field, `is_embedding`, to the `SessionInfo` structure to clearly mark sessions running dedicated embedding models.
Key changes:
- Adds `is_embedding` to the `SessionInfo` interface in `AIEngine.ts` and the Rust backend.
- Updates the `loadLlamaModel` command signatures to pass this new flag.
- Modifies the llama.cpp extension's **auto-unload logic** to explicitly **filter out** and **not unload** any currently loaded embedding models when a new text generation model is loaded. This is a critical performance fix to prevent the embedding model (e.g., used for RAG) from being repeatedly reloaded.
Also includes minor code style cleanup/reformatting in `jan-provider-web/provider.ts` for improved readability.

* feat: move estimateKVCacheSize to BE
* feat: Migrate model planning to backend
This commit migrates the model load planning logic from the frontend to the Tauri backend. This refactors the `planModelLoad` and `isModelSupported` methods into the `tauri-plugin-llamacpp` plugin, making them directly callable from the Rust core.
The model planning now incorporates a more robust and accurate memory estimation, considering both VRAM and system RAM, and introduces a `batch_size` parameter to the model plan.
**Key changes:**
- **Moved `planModelLoad` to `tauri-plugin-llamacpp`:** The core logic for determining GPU layers, context length, and memory offloading is now in Rust for better performance and accuracy.
- **Moved `isModelSupported` to `tauri-plugin-llamacpp`:** The model support check is also now handled by the backend.
- **Removed `getChatClient` from `AIEngine`:** This optional method was not implemented and has been removed from the abstract class.
- **Improved KV Cache estimation:** The `estimate_kv_cache_internal` function in Rust now accounts for `attention.key_length` and `attention.value_length` if available, and considers sliding window attention for more precise estimates.
- **Introduced `batch_size` in ModelPlan:** The model plan now includes a `batch_size` property, which will be automatically adjusted based on the determined `ModelMode` (e.g., lower for CPU/Hybrid modes).
- **Updated `llamacpp-extension`:** The frontend extension now calls the new Tauri commands for model planning and support checks.
- **Removed `batch_size` from `llamacpp-extension/settings.json`:** The batch size is now dynamically determined by the planning logic and will be set as a model setting directly.
- **Updated `ModelSetting` and `useModelProvider` hooks:** These now handle the new `batch_size` property in model settings.
- **Added new Tauri commands and permissions:** `get_model_size`, `is_model_supported`, and `plan_model_load` are new commands with corresponding permissions.
- **Consolidated `ModelSupportStatus` and `KVCacheEstimate`:** These types are now defined in `src/tauri/plugins/tauri-plugin-llamacpp/src/gguf/types.rs`.
This refactoring centralizes critical model resource management logic, improving consistency and maintainability, and lays the groundwork for more sophisticated model loading strategies.
* feat: refine model planner to handle more memory scenarios
This commit introduces several improvements to the `plan_model_load` function, enhancing its ability to determine a suitable model loading strategy based on system memory constraints. Specifically, it includes:
- **VRAM calculation improvements:** Corrects the calculation of total VRAM by iterating over GPUs and multiplying by 1024*1024, improving accuracy.
- **Hybrid plan optimization:** Implements a more robust hybrid plan strategy, iterating through GPU layer configurations to find the highest possible GPU usage while remaining within VRAM limits.
- **Minimum context length enforcement:** Enforces a minimum context length for the model, ensuring that the model can be loaded and used effectively.
- **Fallback to CPU mode:** If a hybrid plan isn't feasible, it now correctly falls back to a CPU-only mode.
- **Improved logging:** Enhanced logging to provide more detailed information about the memory planning process, including VRAM, RAM, and GPU layers.
- **Batch size adjustment:** Updated batch size based on the selected mode, ensuring efficient utilization of available resources.
- **Error handling and edge cases:** Improved error handling and edge case management to prevent unexpected failures.
- **Constants:** Added constants for easier maintenance and understanding.
- **Power-of-2 adjustment:** Added power of 2 adjustment for max context length to ensure correct sizing for the LLM.
These changes improve the reliability and robustness of the model planning process, allowing it to handle a wider range of hardware configurations and model sizes.
* Add log for raw GPU info from tauri-plugin-hardware
* chore: update linux runner for tauri build
* feat: Improve GPU memory calculation for unified memory
This commit improves the logic for calculating usable VRAM, particularly for systems with **unified memory** like Apple Silicon. Previously, the application would report 0 total VRAM if no dedicated GPUs were found, leading to incorrect calculations and failed model loads.
This change modifies the VRAM calculation to fall back to the total system RAM if no discrete GPUs are detected. This is a common and correct approach for unified memory architectures, where the CPU and GPU share the same memory pool.
Additionally, this commit refactors the logic for calculating usable VRAM and RAM to prevent potential underflow by checking if the total memory is greater than the reserved bytes before subtracting. This ensures the calculation remains safe and correct.
* chore: fix update migration version
* fix: enable unified memory support on model support indicator
* Use total_system_memory in bytes

* feat: add getTokensCount method to compute token usage
Implemented a new async `getTokensCount` function in the LLaMA.cpp extension.
The method validates the model session, checks process health, applies the request template, and tokenizes the resulting prompt to return the token count. Includes detailed error handling for crashed models and API failures, enabling callers to assess token usage before sending completions.
* Fix: typos
* chore: update ui token usage
* chore: remove unused code
* feat: add image token handling for multimodal LlamaCPP models
Implemented support for counting image tokens when using vision-enabled models:
- Extended `SessionInfo` with optional `mmprojPath` to store the multimodal project file.
- Propagated `mmproj_path` from the Tauri plugin into the session info.
- Added import of `chatCompletionRequestMessage` and enhanced token calculation logic in the LlamaCPP extension:
- Detects image content in messages.
- Reads GGUF metadata from `mmprojPath` to compute accurate image token counts.
- Provides a fallback estimation if metadata reading fails.
- Returns the sum of text and image tokens.
- Introduced helper methods `calculateImageTokens` and `estimateImageTokensFallback`.
- Minor clean‑ups such as comment capitalization and debug logging.
* chore: update FE send params message include content type image_url
* fix mmproj path from session info and num tokens calculation
* fix: Correct image token estimation calculation in llamacpp extension
This commit addresses an inaccurate token count for images in the llama.cpp extension.
The previous logic incorrectly calculated the token count based on image patch size and dimensions. This has been replaced with a more precise method that uses the clip.vision.projection_dim value from the model metadata.
Additionally, unnecessary debug logging was removed, and a new log was added to show the mmproj metadata for improved visibility.
* fix per image calc
* fix: crash due to force unwrap

- Changed `modelName` to `modelId` for consistency with identifier naming
- Renamed `api_key` to `apiKey` for camelCase consistency
- Updated corresponding methods to use these new identifiers
