Hey everyone, v2.10 just landed for Core and the CLI. Three big things this time.

1. The Browser got stealthy

The internal Browser now handles bot detection properly. Sites that flagged Agent Zero as a bot and were simply unusable in previous versions work now, including Gmail and your social accounts. Concretely:

• Interactive authenticated viewports: sign in yourself, then let the agent work inside your session
• The Browser runtime is shared across chats: sign in once, every chat can use it, and tabs restore automatically
• Native resizing, DOM hover support, multi-page annotations, clearer loading feedback, and voice controls
• Browser follow-up turns now honor your configured model preset

I attached a video of it browsing Gmail.

1. Tag anything with @

Type @ in the composer and get scoped autocomplete for agent profiles, files, folders, skills, and MCP servers. No more typing paths or remembering exact names. Works in the Web UI and the CLI, where completion also covers bounded local or container workspace paths.

1. The CLI speaks ACP

a0 acp starts an Agent Client Protocol stdio server backed by the Agent Zero connector, with session lifecycle and host-tool support. In practice: external editors that support ACP can now host Agent Zero directly. Your editor is the frontend, Agent Zero does the work.

Also worth knowing

• Subordinate agent lifecycle is unified across direct and parallel calls, and failed children are resumable
• Composer drafts persist per chat, so a reload no longer eats your half-written message
• Goal mode prefill in the composer
• Responses and Codex OAuth flows preserve streamed tool calls even when final response envelopes omit them
• Plugin reload prompts now only appear for global changes, not project- or agent-scoped ones
• Hardened extension routes with path-traversal protection, and backup restore no longer affects the active process settings

What sites were blocking your agents before? Curious to hear if this unblocks your workflows.

Qwen dropped 3.8 27B yesterday, so I rented an NVIDIA H200 to see how far the 27B could go on a real coding task in a powerful GPU like that.

Setup

- Qwen3.8-27B, served with vLLM

- 129GB VRAM allocated (weights + KV cache preallocation)

- 64k context window

The target codebase is Agent Zero and its sidebar. But this post is about the model, the same run should transfer to any decently structured codebase

I gave it one screenshot of our sidebar and a short prompt: turn the chat list into a WhatsApp-style list of agent profiles, avatar circle on the left, one persistent chat per profile. We don't have a plan mode in Agent Zero, but Qwen started planning first, and then executed it across 1h49m of continuous work (only one nudge because it couldn't get past the login screen with the masked password, fair)

The interesting part: 64k is nowhere near enough to hold the codebase, so it kept re-reading files right before editing them to make sure they were actually in the context window. It never edited from a stale memory of a file. That level of context discipline is something I mostly associate with much larger models and it was impressive

Anyone else tried it? Curious how it compares for you against much bigger models or even hosted frontier models on multi-hour tasks. This may be one of the best local AI models out there.
