LocalLLMServerManager v3.14.0 — AI Assistant & Multimodal App Copilot

What's New in v3.14.0

🤖 In-App AI Assistant & Natural Language App Control

• External OpenAI-compatible routing with support for LiteLLM and Vertex AI Gemini Flash.
• 12 native application tools via \IAiAppTools\ (live GPU/VRAM telemetry, memory fit analysis, engine control, settings management, and workflow execution).
• Living prompt system loading and formatting markdown prompts dynamically from \Prompts/.

⚡ LiteLLM Model Capabilities & Local Model Exclusion

• Real-time model discovery querying LiteLLM's /model/info\ with automatic fallbacks to /v1/model_info\ and /v1/models.
• Extraction of model capabilities: \SupportsVision, \SupportsFunctionCalling, token limits (\1M, \128k), and provider tags.
• Exclusion of local runtimes (\ollama/, \local/, \llama.cpp) while preserving network-hosted LiteLLM cloud models across LAN and localhost IPs.

🖼️ Multimodal Vision & Image Attachments

• Staged image attachments via file picker (📎) and clipboard paste (\Ctrl+V\ / \Cmd+V).
• Interactive composer bar model selector with capability badges (\👁️, \⚡, context limit pill).

v3.13.1 — Theme-Switching Crash Fix & Comprehensive Automated UI Tests

What's Changed in v3.13.1

🐛 Bug Fixes

• Theme-Switching UI Crash:
  • Eliminated UI crash (\InvalidOperationException: The control StackPanel already has a visual parent ScrollContentPresenter) caused by mutating \Application.Current.Styles\ (\Styles.Clear()) on live visual trees.
  • Implemented non-destructive framework styling in Desktop and Web \App.axaml.cs: base design system styles (\SemiTheme\ + \MatteTheme.axaml) remain stably loaded while theme style buttons cleanly swap color palettes (\MatteCarbon\ vs. \OledBlack) via \ThemeService.
  • Added dispatcher access checks in \ThemeService.SetTheme\ to guarantee thread safety when theme changes are initiated from background or non-UI threads.
  • Added cross-assembly type discovery in \SettingsViewModel.SwitchThemeStyle\ supporting Desktop, Web, and headless test runners.

🧪 Automated Tests

• Automated Headless UI Interaction Tests:
  • Added comprehensive interaction tests across all UI tabs, pickers, and actions in \AvaloniaHeadlessInteractionTests:
    • Settings tab: dynamic theme dropdown, framework style buttons, tool discovery, component status refresh, video/audio pack toggles, and preset manager actions (create, filter, reset, JSON export/import).
    • Telemetry header: status refresh and live GPU/VRAM hardware badges.
    • Engine Studio tab: Test Flight modal toggle, ComfyUI/Forge engine toggles, and preset bar controls.
    • Ollama tab: context slider adjustments, VRAM unload, filter pills, and model deletion confirmation modal flow.
    • Hub tabs (HuggingFace & Civitai): search queries, modality presets, filter tags, and VRAM fit verdict filters.
  • Switched \StudioControlInstantiationTests\ to [AvaloniaFact]\ for proper UI dispatcher affinity.

📦 Distribution

• Synced compiled WebAssembly distribution binaries in \wwwroot/_framework/.

What's Changed

• feat: model deletion, compatibility verdict filters, and multimodal input/output matrix by @spelech in #26
• test: boost overall repository code coverage to 80.2% and all UI viewmodels above 80% by @spelech in #27
• feat: configure Dependabot, sweep NuGet updates, and migrate to MCP 2026-07-28 spec by @spelech in #28
• feat: Studio Presets, Test Flight Wizard, Hardware Fit Badges & Rich Stage Feedback (v3.13.0) by @spelech in #44
• fix: resolve theme-switching crash and add automated UI action tests across all tabs by @spelech in #55
