Google delays Gemini 3.5 Pro launch as AI model falls short of internal benchmarks

Google has delayed the launch of Gemini 3.5 Pro after the model failed to meet internal performance goals, particularly in coding capabilities, pushing it past its original June 2026 release window with no firm new date on the calendar.

Alphabet’s stock dropped approximately 4% during intraday trading following Bloomberg’s report on the postponement.

What went wrong with Gemini 3.5 Pro

Gemini 3.5 Pro reportedly fell short of Google’s own internal benchmarks, with coding capabilities being the primary pain point. The original release window was June 2026. Some sources now point to a potential mid-July launch, possibly around July 17, but only if current efforts to improve the model actually work.

Reports suggest internal dissatisfaction is running high. There have apparently been discussions about scrapping previous base models entirely and rebuilding from scratch. The problems extend beyond just coding: token efficiency, AI agentic features, and the model’s ability to handle long-horizon tasks effectively have all been flagged as structural challenges.

The competitive pressure is real

Multiple prior delays and performance setbacks have compounded the problem. This isn’t the first time Gemini has missed a target, and the repeated discussions about potentially abandoning earlier model iterations suggest that the issues run deeper than typical fine-tuning challenges.

What this means for investors and the crypto-adjacent AI trade

The approximately 4% drop in Alphabet’s stock matters for context. Tech stocks, particularly those tied to AI narratives, have been trading at premium valuations partly because the market assumes these companies will deliver on their AI roadmaps.

For crypto markets, AI-adjacent tokens have increasingly traded in sympathy with major AI developments in traditional tech. A stumble by Google can ripple into sentiment around decentralized AI projects, compute token platforms, and the broader AI-crypto convergence trade. Alphabet is a trillion-dollar-plus company whose stock movements influence broader risk appetite across all speculative asset classes, including crypto.

The key variable to watch now is whether Google can actually ship Gemini 3.5 Pro in the mid-July window that sources have suggested.
