Gemini 3.8 Flash stealth-launches; WSJ says it beats Opus in coding, 3.5 Pro shelved

According to The Wall Street Journal, Google plans to release Gemini 3.8 Flash, codenamed "Skimaki," today. Multiple sources corroborate the report, though no official announcement had been made as of posting time.

Confirmed

• Several users (@markk, @brandongalang) have spotted Gemini 3.8 Flash in consumer apps, indicating an imminent launch
• WSJ reports the version makes major strides in agent-based coding
• In head-to-head tests within Google's internal coding tool Jetski, Google engineers preferred Gemini 3.8 Flash over Anthropic's models (relayed by @kimmonismus citing WSJ)

Unconfirmed

• WSJ says Google has officially abandoned the 3.5 Pro checkpoint, citing limited performance gains over the Flash line; the report as relayed by @Hesamation also speculates Google may skip 3.5 Pro entirely and launch straight to Gemini 4 once training completes — these remain media reports and speculation, with no official Google announcement
• @markk says the launch date is one day later than his earlier prediction — a personal forecast

Why it matters

• If an internal Flash model already beats Anthropic's flagship, it could reshape the competitive landscape for small and mid-sized models
• Dropping 3.5 Pro suggests Google's roadmap may shift to a two-tier structure of "lightweight Flash + Gemini 4 flagship," skipping the intermediate version
