Google Unveils Gemini 2.5: A Leap Forward in AI Reasoning

On Tuesday, Google made waves in the tech industry by launching Gemini 2.5, a new family of AI reasoning models that takes a breather to “think” before providing answers. This innovative approach marks a significant step in the ongoing battle of AI models vying to outperform each other.

Introducing Gemini 2.5 Pro Experimental

To kickstart this new line, Google is rolling out the Gemini 2.5 Pro Experimental model, touted as the most intelligent AI the company has ever developed. This multimodal reasoning model will be available on the Google AI Studio and the Gemini app for users subscribed to the premium AI plan, Gemini Advanced, priced at $20 a month.

A Shift in AI Development

Google has signaled a commitment to embedding reasoning capabilities in all its future AI models. Following OpenAI’s launch of its first reasoning model, o1, in September 2024, major players like Anthropic, DeepSeek, and xAI have joined in, each racing to enhance their own models’ performance. These reasoning models utilize additional computing power and time, allowing them to fact-check and work through problems methodically before delivering answers.

These methodical reasoning techniques have substantially improved AI performance in complex tasks such as mathematics and coding. Many experts believe that these models will be crucial for building AI agents—autonomous systems capable of handling tasks with minimal human input. However, it’s worth noting that these advances come at a higher cost.

Gemini 2.5: A Serious Competitor

While Google has dabbled in AI reasoning models in the past, its December release of a “thinking” version of Gemini was just a warm-up. With Gemini 2.5, Google is making its most robust push yet to surpass OpenAI’s o series. According to Google, this model shows marked improvements over previous frontier AI models and outperforms some leading competitors in various benchmarks.

In terms of practical applications, Gemini 2.5 Pro is reported to excel at building visually appealing web apps and autonomous coding applications. In a benchmark test called Aider Polyglot, Gemini 2.5 Pro achieved a score of 68.6%, outpacing top models from OpenAI, Anthropic, and DeepSeek. However, it faced tougher competition in a separate evaluation, SWE-bench Verified, scoring 63.8%. While it surpassed OpenAI’s o3-mini and DeepSeek’s R1, it fell short of Anthropic’s Claude 3.7 Sonnet, which scored 70.3%.

In the comprehensive off-the-shelf evaluation known as Humanity’s Last Exam, which assesses capabilities in mathematics, humanities, and sciences, Google claims that Gemini 2.5 Pro scored 18.8%, outperforming many rival models.

Impressive Context Capacity

To enhance user experience, Gemini 2.5 Pro is shipped with a generous 1 million token context window, allowing it to process about 750,000 words in one go—longer than the entirety of Tolkien’s “Lord of the Rings” series! And there’s more; an upcoming update is set to boost this capacity to a staggering 2 million tokens.

Google has yet to disclose pricing for the Gemini 2.5 Pro API, but promises more details will be available soon.

Conclusion

As AI technology continues to evolve, Google’s Gemini 2.5 represents a crucial development in making AI models more thoughtful and reasoned. The competitive landscape is heating up, and with advancements like these, the future of AI looks promising.
