Google Introduces Its Most Advanced AI Model Yet

Google has launched Gemini 2.5 Pro Experimental, a new artificial intelligence model designed to reason through problems before delivering answers, a shift that marks a major leap in AI capability, according to the company.

The model, available immediately through Google AI Studio and the Gemini app for subscribers to the company's $20-per-month Gemini Advanced plan, is part of the new Gemini 2.5 family of "thinking" models. It's built to analyze information, weigh context, and make informed decisions across a range of complex tasks including code generation, scientific reasoning, and multimodal interpretation of images, audio, and video.

Google said Gemini 2.5 Pro outperforms several rival models, including those from OpenAI and DeepSeek, in key benchmarks. On a code editing test called Aider Polyglot, Gemini 2.5 Pro scored 68.6%. On SWE-bench Verified, a measure of software development skills, it scored 63.8%, surpassing some competitors but trailing Anthropic's Claude 3.7 Sonnet, which scored 70.3%.

The company said the model also achieved 18.8% on Humanity's Last Exam, a rigorous multimodal test of general knowledge and reasoning. Gemini 2.5 Pro currently supports a 1 million token context window — enough to process roughly 750,000 words at once — and plans to expand to 2 million tokens in the near future.

Google did not immediately announce pricing for API access to the new model but said more details would be shared in the coming weeks.

The launch comes amid growing competition in the AI sector, particularly around reasoning models. Since OpenAI introduced its "o" series in late 2024, companies including Anthropic, xAI, and DeepSeek have released models with similar capabilities. Unlike earlier systems focused mainly on pattern recognition or prediction, reasoning models aim to methodically process information — a feature seen as foundational for autonomous AI agents.

Gemini 2.5 Pro is Google's most serious effort yet to surpass competitors in the rapidly advancing AI landscape. The company said reasoning capabilities will be included in all future Gemini models.
