What's new (v2.0.25)
FEATURES
- Video Understanding From Any Link
Paste a link and the assistant pulls page text, title, and captions. Missing captions trigger on-device transcription. Social links merge post text with attached-video captions, and links with long tracking parameters no longer truncate. Works with most major video and social platforms.
- Real-Time Flight Search
New search_flight tool returns status, delays, gates, and baggage with fallback across FlightAware, AirLabs, AviationStack, AeroDataBox.
IMPROVEMENTS
- Faster first reply in a new chat (skips the relevance scorer).
- Keyboard opens automatically in empty chats.
- Input bar no longer collapses while a draft is in the field.
- Quick Ask, LLM Council, Siri, sub-agents no longer disturb an open OpenAI Responses chat.
- llama.cpp b9279: HunyuanOCR/HunyuanVL unified, DeepSeek-OCR resize fix, faster Metal, NvFP4 LM head, sliding-window crash fix.
- MLX-Swift tag-20260522: Gemma 4 ~24 percent faster, three Gemma 4 crashes fixed, Idefics3 prefill in one pass, Qwen3.5/Qwen3VL/GlmOcr M-RoPE stable.
- GGUF tool calling: Gemma 4, Qwen, LFM2 reliably invoke tools via OpenAI function-calling schema.
- Faster first reply from local GGUF: Metal kernels pre-compile at load.
- Novel Writer on small local models: outline parser recovers from missing tags, character names stay stable, stray markers no longer leak in.
- Banner on small local models showing context size and output cap.
- Reasoning models (GLM-5.1, DeepSeek, OpenAI o-series) now get budget for hidden reasoning plus full structured output.
- Chapter correction pass extends chapters under 70 percent or condenses over 130 percent.
- Token Usage charts now count thinking tokens for reasoning models.
- Duplicate bottom chat action bar removed; all actions in the top-right menu.
BUG FIXES
- Web search falls through Tavily, Brave, LangSearch when first returns nothing.
- macOS screens stuck in light-mode colors now follow Dark Mode immediately.
- Clear Chat on OpenAI Responses drops the server reference and wipes the per-chat workspace.
- Fixed Gemma4-E2B/E4B crash on 32 KB Metal threadgroup devices (incl. iPhone 16 Pro Max).
- Fixed GGUF metadata read crash on external drives or iCloud I/O errors.
- Fixed MLX long-prompt crash on iOS; prompts fed in 512-token chunks on iOS/Mac Catalyst.
- Fixed MLX vision models ignoring an image after a text-only reply.
- Fixed duplicate "Recovered From..." entries on cold launch.
- Custom assistant generation uses a fresh random seed (no more identical results).
- Verbose VoiceOver reads the full response instead of only "Response complete".
- Collapsed thinking preview no longer reads stray letters under VoiceOver.
- Bullet markers decorative; VoiceOver reads item text directly.
- LaTeX/math blocks expose a "Math expression" label for VoiceOver.
