Rebuilt Gemini 3.5 Pro Misses Third Deadline: Google Eyes Stopgap Release

What happened

Gemini 3.5 Pro missed its third consecutive launch deadline on July 17, 2026. The completely rebuilt model still fails to meet basic reliability standards. Google is reportedly considering a temporary "stopgap" release.

Context and impact

At the same time, GPT-5.6 Sol has been publicly available since July 9 and Moonshot AI just released Kimi K3. Google faces growing competitive pressure without a next-generation flagship model. Previous failures: SVG generation and recursive tool-calling; new issues: hallucinations and unstable outputs.

Details

• First deadline: June 2026 — missed (architectural failures)
• Second deadline: July 17, 2026 — missed (hallucinations, unstable outputs)
• Gemini 3.5 Pro cannot match GPT-5.6 in key benchmarks
• Google considering stopgap release as temporary solution
• Google has Gemini 3 Deep Think (released earlier) but lacks a new "Pro" tier
