* 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 Jan API server Swagger UI
- Serve OpenAPI spec (`static/openapi.json`) directly from the proxy server.
- Implement Swagger UI assets (`swagger-ui.css`, `swagger-ui-bundle.js`, `favicon.ico`) and a simple HTML wrapper under `/docs`.
- Extend the proxy whitelist to include Swagger UI routes.
- Add routing logic for `/openapi.json`, `/docs`, and Swagger UI static files.
- Update whitelisted paths and integrate CORS handling for the new endpoints.
* feat: serve Swagger UI at root path
The Swagger UI endpoint previously lived under `/docs`. The route handling and
exclusion list have been updated so the UI is now served directly at `/`.
This simplifies access, aligns with the expected root URL in the Tauri
frontend, and removes the now‑unused `/docs` path handling.
* feat: add model loading state and translations for local API server
Implemented a loading indicator for model startup, updated the start/stop button to reflect model loading and server starting states, and disabled interactions while pending. Added new translation keys (`loadingModel`, `startingServer`) across all supported locales (en, de, id, pl, vn, zh-CN, zh-TW) and integrated them into the UI. Included a small delay after model start to ensure backend state consistency. This improves user feedback and prevents race conditions during server initialization.
Feature:
- Adjust homecreen and chatscreen for mobile device
- Fix tests for both FE and BE
Self-test:
- Confirm runnable on both Android and iOS
- Confirm runnable on desktop app
- All test suites passed
- Working with ChatGPT API
Feat:
- Using Tauri v2 by default
- Add new configuration to initiate mobile app
- Add dependencies needed for mobile build
Test:
- Confirm to be built successfully
- Confirm to keep settings for desktop and build successfully
- Reuse most of components from desktop version
- Add `src-tauri/resources/` to `.gitignore`.
- Introduced utilities to read locally installed backends (`getLocalInstalledBackends`) and fetch remote supported backends (`fetchRemoteSupportedBackends`).
- Refactored `listSupportedBackends` to merge remote and local entries with deduplication and proper sorting.
- Exported `getBackendDir` and integrated it into the extension.
- Added helper `parseBackendVersion` and new method `checkBackendForUpdates` to detect newer backend versions.
- Implemented `installBackend` for manual backend archive installation, including platform‑specific binary path handling.
- Updated command‑line argument logic for `--flash-attn` to respect version‑specific defaults.
- Modified Tauri filesystem `decompress` command to remove overly strict path validation.
* feat: Add GGUF metadata reading functionality
This commit introduces a new Tauri command and a corresponding function to read metadata from GGUF model files.
The new read_gguf_metadata command in the Rust backend uses the byteorder crate to parse the GGUF file format and extract key metadata. This information, including the file's version, tensor count, and a key-value map of other metadata, is then made available to the TypeScript frontend.
This functionality is a foundational step toward providing users with more detailed information about their loaded models directly within the application.
This will be refactored later.
fixes: #6001
* loadMetadata() should return
* Properly throw eror to FE
* Use BufReader to improve performance
