Google is preparing to release its next major Gemini Pro model around July 17, 2026, according to recent projections and insider reports. The company reportedly scrapped its original base model after determining it would not be competitive enough against frontier systems like Anthropic’s Mythos (also referred to as Claude Mythos 5 in some contexts).
This delay from an earlier June target and the decision to retrain from scratch highlight the intense pressure in the current AI model race. Google DeepMind is investing extra time to deliver a stronger contender capable of matching or exceeding the capabilities demonstrated by Anthropic’s latest flagship.
What Happened: Delay and Internal Pivot
Google had initially targeted a June 2026 launch for its next-generation Gemini Pro model (widely expected to be branded as Gemini 3.5 Pro or a similar iteration). However, the release slipped into July as the team gathered more feedback from early testers and made significant adjustments.
According to reports, Google DeepMind ultimately abandoned the original base model because it fell short in direct comparisons with leading models from OpenAI and Anthropic — particularly Anthropic’s Mythos. The team chose to train an entirely new base model from scratch to close the gap.
The projected release window of July 17 has surfaced in recent discussions and market projections as the likely target for broader availability or a significant preview rollout.
Why Anthropic’s Mythos Matters
Anthropic’s Mythos (or Mythos 5) has emerged as one of the most powerful frontier models in 2026. It has drawn attention for strong performance across benchmarks, particularly in areas like security, reasoning, and complex task handling.
Key context around Mythos:
- It has been in limited or private preview for select users and organizations.
- The U.S. government recently lifted certain access restrictions, allowing broader (but still controlled) availability to trusted partners.
- Early reports highlight its capabilities in areas such as cybersecurity risk reduction and advanced reasoning.
Google’s move to retrain its base model specifically to better compete with Mythos underscores how quickly the frontier is advancing and how even small gaps in capability can prompt major internal course corrections.
Google’s Strategy and Strengths
While Google is playing catch-up on raw frontier performance in some areas, it brings distinct advantages:
- Deep ecosystem integration — Seamless connections with Google Search, Workspace, Android, and enterprise tools via Vertex AI.
- Multimodal capabilities — Strong native handling of text, images, audio, and video.
- Enterprise focus — Robust governance, security, and scaling features that appeal to large organizations.
- Developer tools — Continued improvements to the Gemini API and integration with Google Cloud.
The extra development time is reportedly being used to address token efficiency issues flagged by testers and to incorporate lessons from the earlier Gemini 3.5 Flash rollout.
What to Expect from the New Gemini Pro
While official details remain limited until closer to launch, analysts and early signals suggest the upcoming model will emphasize:
- Improved reasoning and complex problem-solving
- Better efficiency (tokens per performance)
- Enhanced agentic capabilities for multi-step tasks
- Stronger performance in competitive benchmarks against Mythos and other frontier models
- Continued focus on safety and responsible scaling
The July 17 timing positions Google to respond directly to recent advances from Anthropic and keep momentum in the ongoing model wars of 2026.
Broader Implications for the AI Race
This development reflects several key trends in mid-2026:
- Intense competition at the frontier — No company can afford to release a model that doesn’t meaningfully advance the state of the art.
- Internal agility matters — Google’s willingness to scrap and retrain a base model shows the speed at which teams must adapt.
- Ecosystem vs. raw capability — Google continues to leverage its massive distribution advantages even as it battles for leadership on pure model performance.
- Enterprise vs. consumer focus — Different labs are emphasizing different strengths (Anthropic on safety/reasoning depth, Google on integration and scale).
The release will also influence developer choices, enterprise adoption decisions, and the broader conversation around AI capabilities and risks.
Outlook: What Happens Next
If the July 17 target holds, we can expect:
- Increased benchmark comparisons between the new Gemini Pro and Anthropic’s Mythos
- Updates on pricing, context windows, and tool-use capabilities
- Potential phased rollout (preview for select users first, then wider availability)
- Follow-on announcements around Gemini ecosystem integrations
The AI model race remains extremely dynamic. Google’s decision to invest extra time rather than rush a weaker model suggests a long-term focus on quality over speed-to-market.
Frequently Asked Questions
When is Google’s next Gemini Pro model expected? Current projections point to around July 17, 2026, following a delay from an earlier June target.
Why did Google delay and retrain the model? Reports indicate the original base model was not competitive enough against leading systems like Anthropic’s Mythos. Google DeepMind chose to train a new base model from scratch.
What is Anthropic’s Mythos? Mythos (sometimes called Mythos 5 or Claude Mythos) is Anthropic’s latest powerful frontier model, noted for strong performance in reasoning, security-related tasks, and complex capabilities. It has been in limited preview with recent expansions in access.
How does this affect developers and users? A stronger Gemini Pro could mean better performance in Google’s ecosystem tools, improved API capabilities, and more competitive options for enterprise and consumer applications.
Will the new model be available immediately on July 17? Likely a phased approach — expect preview or limited access first, followed by broader rollout, similar to previous Gemini releases.
Bottom Line Google is taking a deliberate approach with its next Gemini Pro model, prioritizing competitiveness against Anthropic’s Mythos over an earlier launch date. The projected July 17 release represents another high-stakes moment in the 2026 AI model race, with significant implications for developers, enterprises, and the direction of frontier AI capabilities.
As the battle between Google, Anthropic, OpenAI, and others continues to intensify, users and organizations will benefit from more powerful — and hopefully more reliable — tools.
