Gemini 4 Argon costs 43¢ vs Opus 5.5's $2.43 on same build prompt

MattVidPro · youtube · 2026-10-17

MattVidPro reviews the newly released Gemini 4 Argon, calling it the first Gemini that feels like a genuinely big model:

• Cost comparison: on an identical game-build prompt, Argon cost 43¢ while Opus 5.5 cost $2.43 (a single API test, not a general price ratio); Argon's API pricing is $2/$10 per 1M tokens as a limited-time intro rate — the video's "catch."
• The author ran a full Roblox build in Google's Antigravity using a Roblox Studio MCP server until quota ran out.
• Also covers Meta's Muse Wonder video model (harsh pricing) and the open-weight Muse Spark Open.
• Other news: an OpenAI employee was arrested by the FBI over an alleged hidden recording device (allegation, not convicted); researchers used a public OpenAI model to help build a Chrome exploit for a $250K bounty.
