File browser rebuilt: The File browser now has directory trees, list and icon views, sorting preferences, and its own Settings category. The Editor unifies text and code editing with syntax highlighting, line numbers, search, Markdown previews, and protection against conflicting saves. Remote file access: Browse and edit folders exposed by connected A0 CLI and Launcher instances directly from the Web UI, with granular permission checks. Transfers are hardened with streaming, integrity checks, atomic writes, configurable limits, and safe archive handling. Beta, feedback wanted - A0 Tag: With an Agent Zero instance open in a Launcher tab, press Ctrl/Cmd + Shift + Enter and ask A0 to do anything on your computer from the app you are in. It can also type text directly in place, currently in text editors, email clients, and custom fields. Credential fields are intentionally not supported for security reasons. Tell us what works and what does not. Browser and Desktop: Safari host-browser setup on macOS, Browser tabs that no longer get stuck loading, faster Browser and Desktop startup, and a draggable canvas rail that remembers its position with per-panel desktop and mobile visibility. Security: Fixed WhatsApp media path traversal, Telegram webhook authentication bypass, and IMAP sender-whitelist parsing bypass. If you use these integrations, please update. How to update CLI: open a terminal and type 'a0 update' Web UI: open Settings -> Check for updates -> Review update Launcher: close and reopen the app, then click the Update button New here?

This is the speed release, with some serious resilience work underneath. We halved the time between your prompt and the first token in Agent Zero. In the Launcher, startup time is also cut in half, and saving settings and Instance operations are about 30x faster. Context Doctor: A brilliant community contribution that brings a new recovery layer that repairs malformed tool-call JSON and recovers from empty, repeated, or misformatted model responses. If you run small local models or providers that occasionally misbehave, your runs stop derailing. Context-window indicator: You can now see live token usage, remaining context space, provider-reported costs, cache hits, and generation updates while the agent works. No more guessing what a run costs or when compaction will kick in. Vision sidecar: Another community contribution. Configure a separate vision model alongside your main model. Perfect when your favorite text model has no vision support, or when you want a cheaper model handling images. Also in Core: - The WebUI is faster and steadier during high-rate streaming with progressive Markdown and LaTeX rendering. - Transports now default to Chat Completions, which makes life easier for plugin developers bringing in new providers. - The interactive Browser gets configurable keyboard layouts with better macOS Option and AltGr handling. CLI: - WebSocket recovery keeps running through long outages with safe ownership transfer during reconnects, host changes, and shutdown. - Authorized Chrome/CDP sessions are more stable with persistent browser identities. - Now you get terminal-native ready notifications when TUI or headless runs complete. Launcher: - Startup, Versions, Settings, and Instance operations reuse current data, so everything feels instant while explicit refreshes stay authoritative. - There is a brand new Advanced section for power users: a file-first workspace for Dockerfiles and Compose files with fixed build, run, and teardown actions. - Running local Instances get a native Restart that waits for the Agent Zero UI to be ready.

Hi, I am experiencing a catastrophic error with A0. I keep getting an error 'A0: Message misformat, no valid tool request found.' When I try to fix the error, it disconnects and I get a new error message ' backend disconnected and Token 'B' and ' bad gateway' JSON not valid. Then the entire A0 UI stops working. I restart my Docker container, but the error still persists. Can anyone help, please?

These are almost two hours of demos, Q&A and new features. As always we really appreciated having you, thanks everyone for dropping by! If you missed the call or want to rewatch any part of it, the full recording is now available 🎥

I just wanted to say thank you to the developers of Agent Zero. I’m currently bedridden due to cancer, and having something interesting and challenging to dive into has meant a lot to me. Learning Agent Zero, experimenting with it, and trying to understand what it can do has given me something positive to focus on during a pretty difficult time. What you’ve built is genuinely impressive. I’m still discovering new things about it and feel like I’ve barely scratched the surface of its potential. So I just wanted to say thank you. Your work has made a real difference for me, and I appreciate the time and effort that went into creating something this powerful and accessible.
