* Add voice transcription feature to chat
Introduces voice recording and transcription in the chat window using Whisper models. Adds new components for voice recording and audio waveform visualization, updates feature flags and environment variables, and implements a server API endpoint for audio transcription.
* Fix frequencyData reactivity in VoiceRecorder
Replaces in-place mutation of frequencyData with assignment of a new Uint8Array to ensure Svelte reactivity in the voice visualization.
* Improve AudioWaveform visualization and responsiveness
Refactors AudioWaveform.svelte to use a timeline-based amplitude visualization with dynamic pill count based on container width, smoother animation, and responsive resizing. Updates VoiceRecorder.svelte to remove fixed pillCount and adjust maxHeight for better appearance. These changes provide a more accurate and visually appealing waveform display.
* Improve audio waveform and voice recorder UI
Reduced pill width and gap in AudioWavef…
Replaces CarbonTools and related Carbon icons with Lucide equivalents throughout the UI, updating imports and usage in Svelte components. Updates Hugging Face organization avatar URLs to the new /api/avatars/{org} endpoint in both frontend and backend code. Adds new models to dev and prod YAML configs, and improves the models page layout and filtering. Also updates dependencies to include @iconify-json/lucide and the latest @sinclair/typebox.
* Add billing organization selection
Introduces support for selecting a billing organization for inference requests in HuggingChat. Adds a new billing section in application settings, updates user settings and API to store and validate the selected organization, and ensures requests are billed to the chosen organization by sending the X-HF-Bill-To header. Also updates environment and chart files to include the new OpenID scope required for billing.
* Update +page.svelte
* Remove billingOrganization from default settings
* Fix user settings creation and update test for findUser
The test for updateUser now passes a URL to findUser to match the updated function signature. Also, the updateUser function now inserts the full DEFAULT_SETTINGS object when creating default user settings, ensuring billingOrganization is included.
* Add image reference support for MCP tool calls
Introduces image reference resolution and attachment for MCP tool arguments, allowing tools to accept lightweight image reference strings (e.g. 'latest', 'image_1') and receive resolved image payloads. Updates tool invocation and flow logic to use these references, and improves tool prompt instructions for image input handling.
* Enable multiple file uploads in ChatInput
* Refactor multimodal model selection logic
* Remove 'latest' image reference support
Eliminates handling of the 'latest' image reference in image resolver logic and updates related comments and prompts to only support 'image_1', 'image_2', etc. This simplifies image reference usage and clarifies instructions for tool input parameters.
* Refactor imageRefs to fileRefs for tool payloads
mcp: switch HF MCP login to https://hf.co/mcp?login and accept hf.co in strict checks
- Update examples and Helm envs to use hf.co endpoint
- Relax isStrictHfMcpLogin to allow both hf.co and huggingface.co

Improve MCP tools caching and server selection logic
Replaces single-entry MCP tools cache with a multi-keyed cache based on server configuration, improving cache accuracy for different server sets. Refactors server selection logic in runMcpFlow to better handle custom server lists and selected server names. Removes MCP flow from generate.ts, streamlining text generation logic.
* Add OAuth authentication for MCP servers
Introduces browser-based OAuth flow for MCP servers, including new auth helpers, localStorage management, and UI actions for authentication and sign-out. Server cards now support authentication, and enabled servers include persisted auth headers for API requests. Adds callback handler and route for OAuth completion.
