Google is preparing to play a significant card in the large language model competition.
According to leaked information, Gemini 3.5 Pro is scheduled for an official release on July 17th. It is said to feature a substantial leap in front-end and visual code generation capabilities, reportedly outperforming Anthropic's Fable 5 in several tests, though it still trails behind its rival in areas of complex reasoning and advanced engineering tasks.
Underlying Technical Overhaul
This delayed flagship model is the result of a more fundamental technical rebuild. Reports indicate that Google DeepMind abandoned the original Gemini 2.5 Pro foundation and instead conducted a completely new pre-training process for Gemini 3.5 Pro. This decision pushed the release date from an initially planned June 2026 to July 17th. The move is seen as Google prioritizing quality over speed in response to competitive pressure from both OpenAI's GPT-5.6 and Anthropic's Fable 5.
Front-End Dominance as a Key Feature
The profile of Gemini 3.5 Pro pieced together from leaks suggests a model with distinct strengths, particularly in front-end and visual code generation. Based on testing feedback from developers, the leaked version shows significant improvements in generating interfaces with a professional design aesthetic, better color schemes, and enhanced depth. Its SVG generation capability is substantially stronger, producing complex vector graphics in a single pass with higher accuracy, and it can generate complete, well-structured web pages from simple prompts.
In developer circles, the term "mogging" has gained traction to describe Gemini 3.5 Pro's perceived dominance over competitors in front-end tasks. Anonymous testing on platforms like LM Arena reportedly confirms its superiority in front-end and visual tasks over several rivals, including holding a slight edge over Fable 5 in aspects like artistic conception and atmosphere.
Persistent Shortcomings in Core Areas
However, its front-end prowess does not equate to overall supremacy. In the most demanding areas, such as agent-based tasks, large-scale software engineering, and long-chain reasoning tasks, Gemini 3.5 Pro reportedly still cannot match the performance of Fable 5 or GPT-5.6. Leakers suggest that even with the new foundation, it struggles against these competitors on the hardest problems. Fable 5 maintains strength in heavy engineering tasks like repository-level code debugging, while GPT-5.6 leads in multi-step reasoning. This specialized performance profile likely informs Google's market strategy: to carve out a specific user base with differentiated strengths in front-end and visual code generation.
A Dual-Product Strategy from a Single Foundation
The strategic importance of Gemini 3.5 Pro extends beyond the model itself. Leaks suggest Google is using this new foundation to concurrently develop an image generation model named Nano Banana Pro, aimed directly at competing with OpenAI's GPT-Image 2. This approach allows Google to leverage a single pre-training investment to power both text/code and image generation product lines.
Simultaneously, Google is reportedly advancing the development of Gemini 4 Flash, a model optimized for speed in lightweight scenarios. This multi-model pipeline reflects DeepMind's strategy of covering diverse market needs with specialized models rather than betting on a single flagship. Pricing-wise, reports indicate Google may position Gemini 3.5 Pro as a more cost-effective option to attract budget-conscious enterprise users, seeking a differentiated foothold outside the high-end markets dominated by OpenAI and Anthropic.
Intensifying Competitive Landscape
The delayed release of Gemini 3.5 Pro is a microcosm of the intense competition in the AI arena. OpenAI's GPT-5.6 is expected around July 7th-9th, promising improvements in speed, reliability, and output precision, while Anthropic's Fable 5 continues to lead in heavy engineering tasks.
For the past half-year, the spotlight in AI has largely alternated between OpenAI and Anthropic, with Google maintaining a lower profile. If Gemini 3.5 Pro launches as scheduled on July 17th and its front-end capabilities align with the leaks, it could represent a crucial step for Google in reclaiming influence and competitive voice in this high-stakes race. The market awaits Google's official move to see if Gemini 3.5 Pro can deliver and succeed in the crowded field of large models.
