NEW Gemini 3.5 Pro LEAKS! Google Is Back and Will Rival Fable 5 & GPT-5.6!
⏱ 11 min video · 2 min read5 Jul 2026
TL;DR
Google DeepMind has reportedly set a tentative launch date of July 17, 2025 for Gemini 3.5 Pro, built on a fresh base model rather than the older 2.5 Pro foundation. Leaked outputs suggest the model excels at SVG generation, 3JS scenes, and front-end visual coding, potentially rivaling or beating Claude 4 (Sonnet 5) in those specific areas, though it is not expected to match GPT-5.6 overall.
Key points
1
Gemini 3.5 Pro has a tentative release date of July 17 with a 62% probability estimated by Polymarket users, triggered by the model slug being found in Google Cloud servers.
2
The model is built on a new pre-trained base rather than the Gemini 2.5 Pro foundation, which could make it a significantly larger release than anticipated.
3
Rumored features include a 2 million token context window, a new deep think reasoning layer for math and multi-step logic, and advanced agentic workflow support.
4
Leaked outputs show strong performance in SVG generation, 3JS atmospheric scenes, and one-shot HTML game creation, reportedly outperforming Claude Sonnet 5 in visual coding quality.
5
Google is simultaneously testing multiple unreleased models in Arena, including Gemini 3.5 Flash High, Gemini 3.5 Pro, and a mysterious checkpoint believed to be Gemini 3.6 or Gemini 4 Flash.
Key takeaways
→
If Gemini 3.5 Pro launches around July 17 with competitive pricing, it may become the go-to model for front-end design, SVG, and visual coding tasks over Claude Sonnet 5 or GLM 5.2.
→
Developers can check Lmarena or the Gemini app now for early A/B test access to Gemini 3.5 Pro checkpoints before the official launch.
→
The new base model architecture means benchmarks from Gemini 2.5 Pro should not be used to predict Gemini 3.5 Pro performance — treat it as an entirely new model.
Notable quotes
“If Gemini 3.5 Pro is actually built on a fresh base model, this could be much bigger as a release than people expect.”
“Even compared against Claude Sonnet 5 High, the Gemini outputs look cleaner, more accurate, and more visually polished.”
“This is where the Gemini 3.5 Pro will be able to dethrone all of these models, specifically in front-end design and visual coding quality.”
