Google Scrapped Gemini 3.5 Pro and Rebuilt It From Scratch; Relaunch Targets July 17 With a 2M-Token Window

TechTimes·medium signal

Reporting on July 13 says Google threw out its original Gemini 3.5 Pro and restarted from zero after engineers found structural failures in recursive tool-calling and SVG generation, with Sundar Pichai having already telegraphed the June-to-July slip at I/O. The rebuilt model is now targeting a July 17 release with a 2-million-token context window, a 'Deep Think' reasoning mode, and API pricing around $1.25 per million input tokens. A frontier lab admitting a full rebuild of a flagship — days before ship — is a rare, revealing signal about how hard reliable tool-use has become.
