* server, webui : support continue generation on reasoning models (#22727)
Remove the throw blocking assistant prefill on reasoning models and
orchestrate thinking tags around the prefilled message so the parser
routes the next stream chunks correctly. WebUI drops the reasoning
guard on the Continue button, sends reasoning_content with the
prefilled message and persists partial reasoning on stop so the CoT
survives reload and resume.
Scope : templates with a simple thinking_start_tag / thinking_end_tag
pair. Channel-based templates like GPT-OSS are out of scope, pending
a per-template prefill API in common/chat.
First step toward #21754.
* chore: update webui build output
* server: reject reasoning prefill on channel based templates
* webui: add LLM title generation option
* webui: use chat_template_kwargs for title gen + fix conversation check
* webui: capture firstUserMessage before async streamChatCompletion to fix race condition
* webui: extract LLM title generation into separate method
* webui: use constants and ChatService for LLM generated titles
* webui: rebuild static output
* webui: add LLM title generation setting to new settings location
* webui: use sendMessage in generateTitle
* webui: rebuild static output
* webui: fix formatting
* webui: configurable title prompt, remove think tag regexes, fix TS error
* webui: group title constants into TITLE object, use TruncatedText for CSS truncation and fix race condition
* webui: rebuild static output
* webui: add setting for first-line chat titles
Add an opt-in setting (`titleGenerationUseFirstLine`) to use the first
non-empty line of a prompt as the generated conversation title.
Previously, the complete multi-line prompt was being used, which created
long titles for complex queries. Coupled with
"Ask for confirmation before changing conversation title", the dialog
would overflow.

* webui: fix syntax highlighting lost for non-common languages after streaming
rehype-highlight uses lowlight internally, which only bundles 37 "common"
languages. The streaming code path uses highlight.js directly (192 languages),
so languages like Haskell highlight correctly while streaming but lose all
color once the code block closes. Pass the full lowlight language set to
rehype-highlight so both paths support the same languages.
* webui: rebuild static files after rebase
* Fix Arabic RTL text rendering in web UI
- Add dir='auto' attributes to markdown containers and blocks
- Implement post-processing to add dir='auto' to all text elements
- Replace directional CSS properties with logical properties for proper RTL list alignment
- Ensure bidirectional text support for mixed Arabic/English content
* Clean up commented duplicate function
Remove the commented-out duplicate transformMdastNode function
that was left over from refactoring.
* Fix Arabic RTL text rendering in web UI
- Add dir='auto' attributes to markdown containers and blocks
- Implement post-processing to add dir='auto' to all text elements
- Replace directional CSS properties with logical properties for proper RTL list alignment
- Minor code formatting improvements
This ensures bidirectional text support for mixed Arabic/English content in the llama.cpp web UI.
* Implement rehype plugin for comprehensive RTL text support
- Add rehypeRtlSupport plugin that applies dir='auto' to all elements with children
- Replace DOMParser-based approach with efficient HAST tree processing
- Remove hardcoded element lists for better maintainability
- Ensure proper bidirectional text rendering for mixed RTL/LTR content
* Fix RTL text rendering with rehype plugin and cleanup
* fix: prettier formatting
* fix: include API key in CORS proxy requests for MCP connections
When llama-server is started with --api-key-file and --webui-mcp-proxy,
the /cors-proxy endpoint requires authentication. The WebUI was not
including the Authorization header in proxy requests, causing MCP
connections to fail with 401.
Inject getAuthHeaders() into requestInit when useProxy is true so the
proxy request carries the Bearer token alongside the forwarded target
headers.
Fixes#21167
* fix: simplify headers assignment based on reviewer suggestion
Apply buildProxiedHeaders only when useProxy is true, pass headers
directly to the transport otherwise.
* webui: send reasoning_content back to model in context
Preserve assistant reasoning across turns by extracting it from
internal tags and sending it as a separate reasoning_content field
in the API payload. The server and Jinja templates handle native
formatting (e.g. <think> tags for Qwen, GLM, DeepSeek...).
Adds "Exclude reasoning from context" toggle in Settings > Developer
(off by default, so reasoning is preserved). Includes unit tests.
* webui: add syncable parameter for excludeReasoningFromContext
* chore: update webui build output
* misc : prefer ggml-org models in docs and examples
Prefer referring to known-good quantizations under ggml-org rather than
3rd-party uploaders.
* remove accidentally committed file
* webui: make server the source of truth for sampling defaults
* webui: fix Custom badge for sampling parameters
* webui: log user overrides after server sync
* chore: update webui build output
* fix: Default values for sampling settings config object
* chore: update webui build output
