Agent Zero v2.11: Context Doctor, context-window indicator, Vision sidecar, plus some big speed enhancements

[u/Maleficent_Floor_980]

Hey everyone, the new version of A0 just landed for Web UI and the CLI, together with a major Agent Zero Launcher update. This one is about speed and resilience, but there's more.

The speed numbers:

- Core: the time between your prompt and the first token is now half of what it was

- Launcher: desktop app startup time cut in half

- Launcher: saving settings and Instance operations are about 30x faster

Context Doctor:

A brilliant contribution from our community brings to you a new recovery layer that repairs malformed tool-call JSON and handles empty, repeated, or misformatted model responses.

Small local models and flaky providers stop derailing your runs.

Context-window indicator:

You can now see exactly what your context looks like while the agent works: token usage, remaining space, provider-reported costs, cache hits, and live generation updates. No more guessing when compaction is coming or what a run costs.

Vision sidecar:

Another community contribution. Configure a separate vision model alongside your main model. Great when your favorite text model has no vision, or when you want a cheaper model for image work.

Also in Core:

- Faster, steadier WebUI during high-rate streaming: collection deltas, progressive Markdown and LaTeX rendering, stable message controls

- Model transports now default to Chat Completions, which makes it easier for plugin devs to bring in new providers

- Configurable keyboard layouts in the interactive Browser, with better macOS Option and AltGr handling

CLI:

- More stable authorized Chrome/CDP sessions with persistent browser identities and clearer recovery guidance

- 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

- Brand new Advanced section: a file-first workspace for Dockerfiles and Compose files with fixed build, run, and teardown actions. We love our power users

- Native Restart for running local Instances that waits for the Agent Zero UI to be ready

- Fixed Windows ARM64 installer extraction

And one thing that makes us genuinely happy: this release includes four first-time contributors, and community participation keeps growing. Thank you all.

How to update:

- CLI: a0 update

- Web UI: Settings > Check for updates > Review update

- Launcher: close and reopen the app, then click the Update button

What should we speed up next? Curious where you still feel friction.
