X account @LuminaBench claimed on October 10, 2026 that a model the author calls Gemini 4 Argon has been spotted inside Antigravity, fueling speculation that a release is near. There is no official Google announcement or documentation confirming this; the story remains a single-account leak claim.

The core of the claim is readiness and possible replacement of older models. The author attached one screenshot, but its authenticity cannot be independently verified from the evidence available here.
What was claimed
The post in question was published by X account @LuminaBench at 19:30 KST on October 10, 2026.
- Key quote: "Everything looks ready for Gemini 4 Argon now. Argon is all setup in Antigravity and all old models are leaving soon."
- The author added: "Google please just release this thing already."
- The post included one screenshot-style image attachment.
Phrases like "set up in Antigravity" and "old models leaving soon" are the author's claims, not Google-confirmed facts. The attached screenshot's provenance and integrity are unverified, so it should not be treated as evidence.
The author's timing outlook and community reaction
In a reply posted at 19:36 KST the same day, the author answered a timing question with "didn't meant today, next week it will likely drop, lots of leaks going around." That wording is explicitly personal speculation, not a confirmed schedule.
Replies in the thread show a mix of anticipation and fatigue.
- Some users expressed hope for a release next week.
- Others reacted skeptically, saying releases do not happen on weekends or that they had given up expecting it.
- One reply thread mentioned benchmarks released about two weeks earlier, but the source and substance of those benchmarks are not confirmed in this evidence.
Confirmed versus unconfirmed
The boundary readers should keep in mind is clear.
- Confirmed: a specific X account claimed on October 10, 2026 that Gemini 4 Argon was spotted in Antigravity, and framed a next-week release as personal speculation.
- Unconfirmed: the model name Argon, the Antigravity sighting, any retirement of older models, a next-week release, the screenshot's authenticity, and any official Google position.
- This write-up includes no Google announcement, official document, or general press coverage. It should be updated once official confirmation appears.
Rather than treating a leak account's claim as a confirmed launch, the safer course is to wait for Google's official channels.
