Gemini 4 Pro / Flash: benchmarks, hands-on tests and leaks

A user noticed Google Antigravity removed 3.1 Pro, 3.6 Flash and 3.7 Flash from its model list, and wonders whether the free plan will get access to Gemini 4 when it launches.

Leakers say Antigravity's code already splits Gemini 4 Argon into high, mid and low tiers, with older 3.7/3.6 Flash and 3.1 Pro models removed to make room.

A joking post strings together rumored models such as Opus 5.5, GPT-6 Astra, Grok 4.7 and Gemini 4 Argon, asking whether anyone has tried them.

Meta's new Muse Wonder model outscores GPT-6, Gemini 4 and Claude Fable 5.1 on independent leaderboards, ranking behind only Opus 5.5.

Traders give an 80% chance that Gemini 4.0 is released by October 16, up 25 percentage points in 24 hours.

A developer posted a tongue-in-cheek celebration of "Gemini 4 Argon day," reflecting community anticipation for the Gemini 4 Pro release codenamed Argon.

On Artificial Analysis's composite leaderboard, Opus 5.5 scores 58, Muse Wonder Full 56, GPT-6 Astra 53 and Gemini 4 Argon 53, while Meta says Wonder Full reaches 79% on DeepSWE 1.1.

A developer deep in the Claude and Codex ecosystem says Gemini 4 Argon and Muse Wonder would have to far surpass, not match, Opus 5.5 to make him switch, and criticizes Muse Wonder's lack of design sense.

A video meme jokes that Google engineers are scrambling to rescue the Gemini 4 Argon project after seeing rival Muse Wonder's performance.

A user asks which model people are more excited for, Gemini 4 Argon or Meta's Muse Wonder, hinting that Argon may launch tomorrow.

LuminaBench says all older Gemini models marked Leaving Soon are gone from Antigravity, Argon code including effort levels is already in place, and speculates Google may release Argon tomorrow after Meta's launch.

A user notes that Gemini 3.6 and 3.7 Flash have been removed from Antigravity and that GPT-OSS 120B will also be retired on November 2, and asks whether Gemini 4 Argon could launch today.
