# Gemini 3.5 Pro Still in Preview; GA Reportedly Set for 17 July > Gemini 3.5 Pro is still in preview; leaks put general availability on 17 July after a full rebuild. *Google rebuilt Gemini 3.5 Pro from scratch, delaying it into July. Leaked reporting now points to a 17 July launch — and a security-benchmark twist.* By The FeaturedDaily Desk · FeaturedDaily Canonical: https://featureddaily.com/news/gemini-3-5-pro-preview-ga-leaked-17-july-brief > **Key:** **The news:** Google's Gemini 3.5 Pro is still in limited enterprise preview after a full rebuild. Leaked reporting (~10 July) puts general availability on **17 July 2026** — unconfirmed by Google. ## What happened While OpenAI and Anthropic sprinted out of a July government review, Gemini slipped. Teased at I/O in May, it missed a June target and a **30 June** GA date, and as of 9-10 July remained in limited Vertex AI enterprise preview. Leaked details reported around 10 July now place general availability on **17 July 2026** — a date Google has not confirmed. The reason is now understood: DeepMind reportedly **abandoned the original 2.5 Pro base and ran an entirely new pretraining run**, effectively rebuilding the model from scratch mid-cycle. Restarting a frontier model's pretraining is one of the most expensive moves a lab can make — it burns months of compute and pushes every downstream date back. That is a costly, revealing bet, and the simplest explanation for why the launch kept slipping past target after target. > As of 9-10 July 2026 Gemini 3.5 Pro remained in limited Vertex AI enterprise preview, having missed its June I/O target and a 30 June GA date; leaked details place general availability on 17 July. > — [llm-stats](https://llm-stats.com/llm-updates), 2026-07-10 ## The specs and the security-threshold irony Leaked specs cite a **2M-token context window** (reportedly the largest of any production frontier model), **Deep Think** reasoning gated to the **$250/mo Ultra tier**, and pricing near **$1.25 input / $10 output** per 1M tokens. Treat all of it as leaked, not official — no published benchmarks or confirmed pricing as of 10 July. Here is the twist. Reporting framed Gemini 3.5 Pro as the **only** major frontier model set to ship **without** US government restrictions — apparently because its offensive-security scores sat **below** the unofficial threshold that triggered scrutiny for OpenAI's GPT-5.6 and Anthropic's Fable/Mythos. So Google's slower, less cyber-capable model is the one that ships freely. "Below the threshold" is an inference from reporting, not a Google statement. ## What's next Watch **17 July** for a possible GA — and for Google to publish official specs, benchmarks and pricing that either confirm or deflate the leaks. If the 2M-token window and Deep Think land as reported, Gemini gets a real enterprise pitch; if the date slips again, the rebuild story only gets louder. Until then, Gemini 3.5 Pro stays a preview-only product carrying a big-context, high-tier reasoning promise and an awkward compliment: it ships freely because it scored less dangerous. ## Key takeaways - As of 9-10 July 2026, Gemini 3.5 Pro was still in limited Vertex AI enterprise preview, having missed its June I/O target and a 30 June GA date. - Leaked reporting puts general availability on 17 July 2026 — not confirmed by Google. - The delay is attributed to DeepMind abandoning the 2.5 Pro base and rebuilding the model from scratch with an entirely new pretraining run. - Leaked specs cite a 2M-token context window, Deep Think reasoning gated to a $250/mo Ultra tier, and roughly $1.25 input / $10 output per 1M tokens. - Gemini 3.5 Pro was framed as the only major frontier model shipping without US government restrictions — reportedly because its offensive-security scores fell below the threshold that snagged OpenAI and Anthropic. ## FAQ ### Is Gemini 3.5 Pro available yet? No. As of 9-10 July 2026 it remained in limited Vertex AI enterprise preview, having missed a 30 June GA date. Leaked reporting points to a 17 July launch, which Google has not confirmed. ### Why was it delayed? DeepMind reportedly abandoned the 2.5 Pro base and ran an entirely new pretraining run — rebuilding the model from scratch mid-cycle, which pushed the timeline back. ### Are the specs official? No. The 2M-token context window, Deep Think on the $250/mo Ultra tier, and roughly $1.25 input / $10 output pricing all come from leaks. There were no published official benchmarks or confirmed pricing as of 10 July. ### Why does it ship without US government restrictions? Reporting says its offensive-security scores fell below the unofficial threshold that triggered scrutiny for OpenAI and Anthropic. That inference isn't a Google statement. ## Sources - [AI Updates Today (July 2026) — Latest AI Model Releases](https://llm-stats.com/llm-updates) — llm-stats, 2026-07-10 - [Best AI Models in July 2026: ChatGPT, Claude, Gemini & Grok](https://felloai.com/best-ai-models/) — Fello AI, 2026-07-09 - [AI News Today July 9 2026: 15 Biggest Stories](https://www.buildfastwithai.com/blogs/ai-news-today-july-9-2026) — BuildFastWithAI, 2026-07-09
