- Replace raw text parsing with step‑based streaming logic in `ThinkingBlock`.
- Introduced `stepsWithoutDone`, `currentStreamingStepIndex`, and `displayedStepIndex` to drive the streaming UI.
- Added placeholder UI for empty streaming state and hide block when there is no content after streaming finishes.
- Simplified expansion handling and bullet‑point rendering, using `renderStepContent` for both streaming and expanded views.
- Removed unused `extractThinkingContent` import and related code.
- Updated translation keys and duration formatting.
- Consolidate reasoning and tool‑call presentation in `ThreadContent`.
- Introduced `shouldShowThinkingBlock` to render a single `ThinkingBlock` when either reasoning or tool calls are present.
- Adjusted `ThinkingBlock` props (`text`, `steps`, `loading`) and ID generation.
- Commented out the now‑redundant `ToolCallBlock` import and removed its conditional rendering block.
- Cleaned up comments, unused variables, and minor formatting/typo fixes.
- General cleanup:
- Updated comments for clarity.
- Fixed typo in deletion loop comment.
- Minor UI tweaks (bullet styling, border handling).
- **ThinkingBlock**
- Added `ThoughtStep` type and UI handling for step kinds: `thought`, `tool_call`, `tool_output`, and `done`.
- Integrated `Check` icon for completed steps and formatted duration (seconds) display.
- Implemented streaming paragraph extraction, fade‑in/out animation, and improved loading state handling.
- Updated header to show dynamic titles (thinking/thought + duration) and disabled expand/collapse while loading.
- Utilized `cn` utility for conditional class names and added relevant imports.
- **ThreadContent**
- Defined `ToolCall` and `ThoughtStep` types for type safety.
- Constructed `allSteps` via `useMemo`, extracting thought paragraphs, tool calls/outputs, and a final `done` step with total thinking time.
- Passed `steps`, `loading`, and `duration` props to `ThinkingBlock`.
- Introduced `hasReasoning` flag to conditionally render the reasoning block and avoid duplicate tool call rendering.
- Adjusted rendering logic to hide empty reasoning and ensure tool call blocks only appear when no reasoning is present.
- **useChat**
- Refactored `getCurrentThread` for clearer async flow while preserving temporary‑chat behavior.
- Captured `startTime` at message creation and computed `totalThinkingTime` on completion.
- Included `totalThinkingTime` in message metadata when appropriate.
- Minor cleanup: improved error handling for image ingestion and formatting adjustments.
Overall, these changes provide a richer, step‑by‑step thinking UI, better state handling during streaming, and expose total thinking duration for downstream components.
This icon doesn't do anything on chatInput but just an indicator when the proactive capability is activated. Safely remove since this can be indicated from the model dropdown
This commit introduces Japanese as a supported language in the web application.
Key changes include:
- Addition of a new `ja` locale with 15 translated JSON resource files, making the application accessible to Japanese-speaking users.
- Update of the `LanguageSwitcher.tsx` component to include '日本語' in the language selection dropdown menu, allowing users to switch to the new language.
- The localization files were added by creating a new `ja` directory under `web-app/src/locales` and translating the content from the `en` directory.

* feat: support multimodal tool results and improve tool message handling
- Added a temporary `ToolResult` type that mirrors the structure returned by tools (text, image data, URLs, errors).
- Implemented `convertToolPartToApiContentPart` to translate each tool output part into the format expected by the OpenAI chat completion API.
- Updated `CompletionMessagesBuilder.addToolMessage` to accept a full `ToolResult` instead of a plain string and to:
- Detect multimodal content (base64 images, image URLs) and build a structured `content` array.
- Properly handle plain‑text results, tool execution errors, and unexpected formats with sensible fallbacks.
- Cast the final content to `any` for the `tool` role as required by the API.
- Modified `postMessageProcessing` to pass the raw tool result (`result as any`) to `addToolMessage`, avoiding premature extraction of only the first text part.
- Refactored several formatting and type‑annotation sections:
- Added multiline guard for empty user messages to insert a placeholder.
- Split the image URL construction into a clearer multiline object.
- Adjusted method signatures and added minor line‑breaks for readability.
- Included extensive comments explaining the new logic and edge‑case handling.
These changes enable the chat system to handle richer tool outputs (e.g., images, mixed content) and provide more robust error handling.

This commit introduces a change to prevent **Markdown** rendering issues where a dollar sign followed by a number (like **`$1`**) is incorrectly interpreted as **LaTeX** by the rendering engine.
---
The `normalizeLatex` function in `RenderMarkdown.tsx` now explicitly escapes these sequences (e.g., **`$1`** becomes **`\$1`**), ensuring they are displayed literally instead of being processed as mathematical expressions. This improves the fidelity of text that might contain currency or similar numerical notations.
* enable new prompt input while waiting for an answer
* correct spelling of handleSendMessage function
* remove test for disabling input while streaming content
- Added shallow equality guard for `connectedServers` state to prevent redundant updates when the fetched server list hasn't changed.
- Updated error handling for server fetch to only clear the state when it actually contains data.
- Introduced `newHasActiveModels` variable and conditional updater for `hasActiveModels` to avoid unnecessary state changes.
- Adjusted error handling for active model fetch to only set `hasActiveModels` to `false` when the current state differs.
These changes reduce needless re‑renders and improve component performance.
The `listSupportedBackends` function now includes error handling for the `fetchRemoteSupportedBackends` call.
This addresses an issue where an error thrown during the remote fetch (e.g., due to no network connection in offline mode) would prevent the subsequent loading of locally installed or manually provided llama.cpp backends.
The remote backend versions array will now default to empty if the fetch fails, allowing the rest of the backend initialization process to proceed as expected.
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.
