Focusing on complex thinking tasks, Gemini 2.5 is an experimental version of 2.5 Pro. Gemini 2.5 Pro recently gained attention by ranking #1 on LMArena by a “significant margin.” LMArena is an open-source platform for crowdsourced AI benchmarking, created by researchers from UC Berkeley SkyLab. Gemini 2.5 Pro is currently available in Google AI Studio and for Gemini Advanced users in the Gemini app, and eventually coming to Vertex AI.
Classified as thinking models, Gemini 2.5 uses reasoning of its thoughts before outputting insightful responses:
In the field of AI, a system’s capacity for ‘reasoning’ refers to more than just classification and prediction. It refers to its ability to analyze information, draw logical conclusions, incorporate context and nuance, and make informed decisions.
Gemini 2.5 scans information sources such as text, audio, images, video and even entire code repositories and then comprehends complex datasets and solves complex problems.
Smarter AI has been on Google’s mind for quite awhile with research into reinforcement learning and chain-of-thought prompting and culminated with their first thinking model, Gemini 2.0 Flash Thinking.

Gemini 2.5 Pro Capabilities
Gemini 2.5 Pro is considered the most advanced model for complex tasks based on the LMArena leaderboard — “which measures human preferences — by a significant margin, indicating a highly capable model equipped with high-quality style.”
Gemini 2.5 Pro excels in common coding, math and science benchmarks by empasizing strong reasoning and code capabilities. 2.5 Pro is proficient in math and science benchmarks like GPQA and AIME 2025 and ranked state-of-the-art 18.8% across models without tool use on Humanity’s Last Exam.
Gemini 2.5 Pro even scored 63.8% on SWE-Bench Verified, the industry standard for agentic code evals. Gemini 2.5 Pro is taking AI to new heights with its advanced reasoning abilities:
We’ve been focused on coding performance, and with Gemini 2.5 we’ve achieved a big leap over 2.0 — with more improvements to come. 2.5 Pro excels at creating visually compelling web apps and agentic code applications, along with code transformation and editing.
