Google Antigravity release notes: 2.11.0 renders HTML artifacts, CLI 1.1.22 selects models

Google Antigravity 2.11.0 now renders HTML artifacts directly in chat. A generative UI artifact is an HTML result rendered inside the conversation instead of being left as code-only output. The release also supports KaTeX, Chart.js and Plotly in widgets and artifact previews. Google dates the release to August 26 and says rollout is gradual.

Google Antigravity release notes: HTML artifacts in chat

The new support lets a chart, formula or interactive HTML view appear where the work is already being discussed. Version 2.11.0 can also display YAML front matter as a formatted metadata card in Markdown files and artifacts.

Files and rules gain several direct connections:

• @path/to/file can reference and inline external files in AGENTS.md and custom rule files.
• A rules: key in an agent's Markdown frontmatter can bind specific rule files to that agent.
• The project can discover skills, agents and rules from skills.json, agents.json and rules.json files in project subdirectories.

The terminal panel can be split side by side with its split button. The keyboard shortcut is Ctrl+Shift+5 on Linux and Windows, or Cmd+\ on Mac.

Antigravity CLI 1.1.22 selects a model with one command

Antigravity CLI is the product's command-line interface. Version 1.1.22, published August 27, adds /model <name>. It switches to the first model matching a name, slug or label and saves the choice as your default. /model without an argument still opens the picker. An unrecognized name prints the valid choices.

The release also fixes selectable reasoning effort for Gemini 3.1 Pro and Gemini 3.5 Flash when you authenticate with a Gemini API key.

Human step

In an active Antigravity CLI session, enter /model <name> to select and save a model directly. Use /model without an argument to open the picker.

Short example: use the new Antigravity feature

Once 2.11.0 reaches your account, you can ask the agent for an HTML artifact that renders in chat. The changelog confirms Chart.js support in these artifacts.

Create a self-contained HTML artifact in chat that visualizes the data in reports/weekly.json with one Chart.js chart. Label each value with its source key, state which rows were omitted and why, and do not invent missing values.

A good result should:

• Render as an HTML artifact directly in chat.
• Make every chart value traceable to a key in the source file.
• Leave missing values missing.
