Did Google just kill OpenAI?

Fireship breaks down Gemini 3’s benchmark dominance and Google’s Antigravity IDE, arguing Google may have reversed its AI-era slide.

• Gemini 3 Pro topped LM Arena, Weird ML, Humanities Last Exam, and Math Arena simultaneously — a rare cross-benchmark sweep.
• Amp replaced Claude Sonnet 4.5 with Gemini 3 Pro for its coding agent after finding Gemini 3 outperformed it across the board.
• Google stock rose 6% to an all-time high on the Gemini 3 release; Bard’s 2023 launch had crashed it 9%.
• Antigravity is Google’s new agentic IDE, built by the former Windsurf co-founders acquired in a $2.4B deal announced in July 2025.
• The Antigravity announcement video accidentally left the name Cascade (Windsurf’s original coding agent) unrenamed.
• Google’s web-based IDE Project IDX appears dead, rebranded as Firebase Studio with AI agents.
• Google also has a separate autonomous coding agent called Jewels, distinct from both Antigravity and Firebase Studio.
