Antigravity model picker is missing Gemini 4 Argon

From lorddavidDone 1 day agovia agent-mcp

The Antigravity CLI already exposes the Gemini 4 Argon models for my account, but AgentsRoom does not offer them in the model picker of an Antigravity agent (Add agent / Edit agent), so I cannot select them.

agy models (agy 1.4.3, Windows 11) returns:

gemini-4-argon-low / Gemini 4 Argon (Low)
gemini-4-argon-medium / Gemini 4 Argon (Medium)
gemini-4-argon-high / Gemini 4 Argon (High) alongside gemini-3.8-flash-, claude-opus-5-5-, claude-sonnet-5-5-* and gpt-oss-120b-medium.

AgentsRoom 1.224.0 (latest) only lists the Gemini 3.x Flash models and Claude models for Antigravity. No changelog entry mentions Gemini 4 Argon.

AgentsRoom diagnostics

App version: 1.224.0
OS: win32 10.0.26300 (x64)
Agent CLI: claude
App language: system

Expected behavior

The Antigravity model picker lists gemini-4-argon-low, -medium and -high, as returned by agy models.

Actual behavior

Gemini 4 Argon models are absent from the picker; only Gemini 3.x Flash and Claude models are offered.

Steps to reproduce

Sign in to Antigravity with a Google subscription that has Gemini 4 Argon. 2. Run agy models: the three gemini-4-argon-* ids are listed. 3. In AgentsRoom, open Edit agent on an Antigravity agent and open the model picker: Gemini 4 Argon is missing.

This will be available in the next version. The model list in AgentsRoom had not yet been updated with Gemini 4 Argon. Low, Medium and High are now included in the Antigravity model picker when adding or editing an agent. If the issue persists after this update, please reopen the ticket with as much detail as possible; a screenshot or video helps.
