Arc 0.51.83 — Music from Home, with CPU-only search and playback

Published October 19, 2026 · Windows x64 development release.

Ask for a song or playlist, and keep working. Type a music request on Home or in chat, or say it after “Hey Arc”. Arc opens Music, fills in your search and plays the first public YouTube match inside the app. No pasted link or chat-model generation is needed.

Try it

  • “Play Get Lucky by Daft Punk.”
  • “Search for the song Take On Me on YouTube.”
  • “Find an 80s hits playlist.”
  • “Search YouTube for Get Lucky and play it.”
  • “Pause music”, “resume music”, “skip this song”, “previous song” or “stop music”.

Use Settings → Music · YouTube, or Settings → Plugins → YouTube → Audio player, for the player and saved playlist library. Install Agent Reach from Plugins if prompted. Enable Hey Arc and microphone access for voice commands.

What CPU-only means

Direct music requests are recognized by a small local command parser before the chat model runs. Search and stream resolution use the managed YouTube runtime; the persistent audio player handles decoding and playback. Music does not load an LLM, acquire an inference/GPU allocation, or run Ultra reasoning. Typed music confirmations also skip text-to-speech.

Your selected AI model stays available for other work. This does not mean the entire Arc process always shows zero GPU usage: the interface can use GPU rendering, and Hey Arc still uses the configured speech engine. Internet access is required for YouTube search and streaming. General video research remains on Arc’s research path.

Music features included in this release

  • Search from Home or chat: play, search and find requests for songs or playlists open Music automatically. The title and Song/Playlist choice are filled in. A missing title gets a quick local prompt instead of a model call or a guessed song.
  • A player inside Arc: Play/Pause, Previous/Next, seeking, volume, Stop, a collapsible floating player and the current queue. Playback continues across chats, settings navigation and minimizing Arc. Voice searches do not bring a hidden window to the foreground.
  • Playlist support: save, rename and filter up to 100 playlist shortcuts. An exact saved playlist name takes priority. Public playlist searches load the first match, up to 100 tracks; song searches queue up to five matches. These are search results, not personalized recommendations.
  • Voice and text transport controls: Pause and Resume are explicit actions. A user-requested pause stays paused when a voice conversation finishes. Successful playback is confirmed by the audio player, not just a resolved URL.
  • More resilient streams: complete and validate audio segments in small RAM buffers, retry temporary failures at the same byte position, and discard incomplete data before decoding. Stop and track changes cancel outstanding work. Clearer messages distinguish network, timeout, format and HTTP failures.
  • Existing choices remain: pasted links, saved playlists and the official browser fallback are still available. Arc does not save music files or import browser cookies.

Also included since public 0.51.75

  • 0.51.76 — Research recovery: stalled read-only research gets one evidence-based final-answer attempt, preserving sources, uncertainty and explicit stops. Missing requested screenshots or files remain incomplete.
  • 0.51.77 — Workstation task records: compact records retain created-file revisions, source reads, screenshots, vision analyses and test results. “Recorded work” appears in the existing interface, with eight detailed workstation workflows.
  • 0.51.78 — Focus workflow repairs: better handling of negative constraints, file creation and chunk finalization, typed JavaScript assertions, test repair, multi-source research, and readable page screenshots with vision receipts.
  • 0.51.79–0.51.83 — Music: playlist shortcuts, in-app audio, text/voice commands, stream resilience, and CPU-only Home search/playback. The current in-app player supersedes the initial browser-only music behavior.

Existing models, chat history, guides, research, coding, screen sharing and other tools remain available. Normal updates preserve the separately stored workspace and model files.

Validation and current limits

The 0.51.83 checks passed 43 focused music/wake tests, six main-process IPC/protocol tests, and a voice-controller test covering four initial music requests and subsequent playlist searches. Main-process tests confirmed zero model-runtime, browser and context-preparation calls for the covered direct music commands. The production TypeScript/Vite build passed.

Electron checks exercised the production player and navigation hook with decoded audio. Live song and playlist checks covered search, playback, pause/resume, seeking, hidden-window behavior and advancing a playlist. The packaged build also passed live playback checks. These runs muted speakers and verified decoded audio/time advancement; they are not an acoustic microphone/speaker test or a guarantee of access to every track. The previous stream-repair checks played complete tracks past the reported two-minute boundary; they did not reproduce or prove the exact original cause of every reported interruption.

Public YouTube stream playback is experimental, not an official YouTube integration. Private, sign-in-only, live, protected or otherwise inaccessible streams are not bypassed. Availability can change; use the official player when appropriate. Spotify and iHeartRadio playback are not included. No new model-speed or VRAM benchmark is claimed.

Download and verification

The installer is not Windows Authenticode-signed. Signed Arc updater metadata and download hashes are separate integrity checks. No VirusTotal result is claimed for this exact installer. Model weights remain separate downloads.
