Google delays broader Gemini 3.5 Pro release after coding results disappoint internally

Gemini 3.5 Pro, promised a June ship date at I/O 2026, remains unreleased after a late-June retrain meant to fix coding shortfalls disappointed internally, per ten current and former employees. Google is now testing it alongside an upgraded Flash model with partners and has set no new date — a rare public stumble on coding, the exact axis where Gemini had been closing on frontier rivals. Alphabet shares fell about 4% on the report.
