Google has pushed back the release of its next-generation Gemini 3.5 Pro model from June to July 2026, a delay that comes as the company grapples with an accelerating wave of high-profile departures from its AI divisions.

CEO Sundar Pichai had publicly indicated that Gemini 3.5 Pro would arrive in June. According to reporting by Business Insider, confirmed by multiple outlets including The Times of India and Crypto Briefing, the company now says it needs additional time to refine the frontier model before launch.

The postponement landed against a backdrop of mounting pressure on Google's AI ambitions.

Five Top Researchers Depart in Seven Days

The most striking development is the speed of the talent drain. A June 25 analysis by 24/7 Wall St. reported that five top Google AI researchers departed within a seven-day window, a concentration of exits that has rattled investors and competitors alike.

The departures build on losses already documented throughout June. Nobel laureate John Jumper, a co-lead on DeepMind's AlphaFold project, announced he was leaving for Anthropic, as reported by Reuters and TechCrunch. Transformer co-author Noam Shazeer departed for OpenAI in what was widely described as one of the year's most significant talent moves.

Crypto Briefing reported on June 24 that Google is set to lose two additional researchers to Anthropic and OpenAI, deepening an exodus that has drawn scrutiny from across the industry.

Anthropic's surging $96.5 billion valuation, reported by NAI500, has made it an increasingly powerful magnet for AI talent — offering both equity upside and a research culture that many departing employees have cited as a draw.

Alphabet Stock Takes a Hit

The competitive anxiety reached financial markets on June 22, when CNBC reported that Alphabet experienced its worst trading day in over a year, driven by concerns over the high-profile exits and whether DeepMind can maintain its position at the frontier of AI development.

Fortune raised the question directly in a June 23 piece: as top talent leaves Google DeepMind, can the lab remain at the forefront of AI development?

Google Scrambles to Reorganize Its Coding Effort

The Information reported on June 25 that Google has revamped its AI coding strike team as it struggles to catch up with Anthropic in the rapidly growing market for AI-assisted software development. The move signals an internal acknowledgment that Google arrived late to a category where Anthropic and OpenAI have built commanding leads.

A June 1 CNBC analysis noted that while Microsoft and Google are "absolutely critical" competitors in AI coding, both companies entered the space well behind their rivals.

What the Delay Means for Gemini

Gemini 3.5 Pro is positioned as Google's answer to the latest flagship models from OpenAI and Anthropic. The company has already released Gemini 3.5 Flash, a faster, lighter variant, but the Pro version is expected to deliver the benchmark performance needed to compete at the frontier.

Pushing the launch to July gives Google more time to close performance gaps, but it also cedes additional ground to competitors who are not standing still. Anthropic has been steadily expanding its Claude lineup, while OpenAI continues to iterate on its GPT family.

The talent situation compounds the challenge. Replacing researchers of Shazeer and Jumper's caliber is not simply a matter of hiring — their institutional knowledge and research momentum take years to rebuild.

A Pivotal Moment for DeepMind

The combination of a delayed flagship model, a talent exodus, and a tumbling stock price marks a pivotal moment for Google's AI division. Once seen as the undisputed leader in AI research through DeepMind, the company now faces credible questions about whether it can maintain that position.

For now, Google's response has been organizational: restructuring teams, revamping its coding effort, and buying time with a one-month delay. Whether that will be enough to stem the tide — and deliver a Gemini 3.5 Pro that can genuinely compete — remains to be seen.

The July launch will be closely watched not just by developers and enterprise customers, but by investors and competitors assessing whether Google's AI era is one of dominance or decline.
