On Tuesday, Google introduced Gemini 2.5, a groundbreaking family of AI reasoning models designed to enhance the thought process before answering questions. This launch centers on Gemini 2.5 Pro Experimental, a multimodal AI model billed as Google’s most advanced offering to date. Available immediately on the Google AI Studio and the Gemini app as part of a $20-a-month subscription, Gemini 2.5 Pro represents a significant stride in AI reasoning capabilities.
With the introduction of these models, Google is asserting that all future AI systems will incorporate robust reasoning functions. The move follows OpenAI’s launch of its first AI reasoning model, o1, in September 2024. This development sparked competitive responses from companies like Anthropic, DeepSeek, and xAI, all of which have rolled out their own reasoning models. These models leverage increased computational power and time to accurately analyze and answer queries.
The reasoning techniques have significantly improved the performance of AI models in tasks such as math and coding. Many industry experts view these reasoning models as essential to developing AI agents that can operate autonomously with minimal human oversight, though the added complexity comes at a higher financial cost.
Google has previously explored AI reasoning with a version of Gemini released in December. However, below this latest effort, Gemini 2.5 aims to surpass OpenAI’s previous models. Google claims that Gemini 2.5 Pro excels compared to its own prior models and leading competitors in various performance benchmarks. For instance, it scored 68.6% on Aider Polyglot, surpassing top models from OpenAI and Anthropic, while achieving a score of 63.8% in software development tasks.
Gemini 2.5 Pro boasts an impressive one million token context window, allowing it to process about 750,000 words at once, with plans to double this capacity soon. Pricing details for the API will be disclosed in the upcoming weeks.
