Google Launches Gemini 2.5 AI With Advanced Reasoning Skills

Google has launched Gemini 2.5, its most advanced AI reasoning model to date. Introduced Tuesday, the new Gemini 2.5 Pro Experimental model is designed to "pause and think" before generating responses, aiming to deliver more accurate, thoughtful answers by using additional compute power and reasoning time.

Available now through Google AI Studio and the Gemini app (for $20/month Gemini Advanced subscribers), this release marks a major step in Google's push to build intelligent AI agents capable of solving complex tasks with minimal human input.

Google indicated that all future AI models will include built-in reasoning capabilities, reflecting a long-term shift toward more deliberative, intelligent systems.

A Competitive Leap in Reasoning

AI reasoning models have become a focal point in 2025’s tech race, ever since OpenAI introduced its o1 model in September 2024. These models use more time and computation to fact-check, analyze, and reason through prompts—unlocking higher performance, especially in math, logic, and code generation.

Now, Google joins other players like Anthropic, DeepSeek, and xAI with a flagship reasoning model of its own.

Performance Highlights

According to Google, Gemini 2.5 Pro outperforms previous Gemini models and several leading competitors in key benchmarks:

• Aider Polyglot (code editing): 68.6% - Higher than OpenAI, Anthropic, and DeepSeek models

• SWE-bench Verified (software development): 63.8% - Outperforms OpenAI’s o3-mini and DeepSeek’s R1, but falling short of Anthropic’s Claude 3.7 Sonnet (70.3%)

• Humanity’s Last Exam (math, humanities, science): 18.8% - Outperforms most flagship multimodal models

Additionally, Gemini 2.5 Pro is optimized for visually compelling web apps and agentic coding use cases, aligning with the broader goal of building autonomous AI systems.

Context Window and Future Plans

Gemini 2.5 Pro ships with a 1 million token context window, allowing the model to process around 750,000 words in one session—longer than the entire Lord of the Rings trilogy. Google says support for 2 million tokens is coming soon.

The company hasn’t yet released API pricing for Gemini 2.5 Pro, but promises more information in the weeks ahead.

What This Means

The launch of Gemini 2.5 Pro signals a growing shift in AI design: from speed and scale toward deliberation, accuracy, and deeper reasoning.

For developers, it could mean faster progress in building complex tools, especially in code-heavy and multimodal environments. For users, it may bring more reliable, context-aware AI experiences across web and mobile apps.

And for the industry as a whole, Google’s move confirms what many already see coming—reasoning models are no longer experimental; they’re foundational.
