IMO 🥇achieved! Really proud to have contributed to the post-training and thinking side of this model! Getting closer to ASI!
An advanced version of Gemini with Deep Think has officially achieved gold medal-level performance at the International Mathematical Olympiad. 🥇 It solved 5️⃣ out of 6️⃣ exceptionally difficult problems, involving algebra, combinatorics, geometry and number theory. Here’s how 🧵

Gemini 2.5 Deep Think is finally out! From winning IMO gold medal to to tackling hard problems in general, this model uses parallel thinking to achieve so. A big step towards superintelligence.
For researchers, scientists, and academics tackling hard problems: Gemini 2.5 Deep Think is here. 🤯 It doesn't just answer, it brainstorms using parallel thinking and reinforcement learning techniques. We put it into the hands of mathematicians who explored what it can do ↓

AI now beats every single human in the hardest college entrance exam in India, the IIT JEE. Bytedance silently published this result this week. The top scorer was Rajit Gupta with 332/360, but Google's Gemini 2.5 Pro was at rank 1 with 336/360.

Google’s updated Gemini 2.5 Pro now leads the AI intelligence frontier, matching OpenAI's o3 in our independent benchmarks Google’s May update of Gemini 2.5 Pro regressed in some performance evaluations compared to the initial March release. This June update not only fixes

We improved our Gemini 2.5 Pro model across the board (again)! This time the model will be GA. 🚢🚢🚢
Our latest Gemini 2.5 Pro update is now in preview. It’s better at coding, reasoning, science + math, shows improved performance across key benchmarks (AIDER Polyglot, GPQA, HLE to name a few), and leads @lmarena_ai with a 24pt Elo score jump since the previous version. We also

Super proud to have been working on Gemini 2.5 Pro Deep Think with so many impressive SoTA results. Hope it can generate some deep thoughts that are useful for you 🤔
Deep Think in 2.5 Pro has landed. 🤯 It’s a new enhanced reasoning mode using our research in parallel thinking techniques - meaning it explores multiple hypotheses before responding. This enables it to handle incredibly complex math and coding problems more effectively.

🚨Breaking: @GoogleDeepMind’s latest Gemini-2.5-Pro is now ranked #1 across all LMArena leaderboards 🏆 Highlights: - #1 in all text arenas (Coding, Style Control, Creative Writing, etc) - #1 on the Vision leaderboard with a ~70 pts lead! - #1 on WebDev Arena, surpassing Claude
We’re releasing an updated Gemini 2.5 Pro (I/O edition) to make it even better at coding. 🚀 You can build richer web apps, games, simulations and more - all with one prompt. In @GeminiApp, here's how it transformed images of nature into code to represent unique patterns 🌱

We just made Gemini 2.5 Pro even better at coding with an improved @lmarena_ai ELO. Hope you’ll like it 🚢
Gemini 2.5 Pro just got an upgrade & is now even better at coding, with significant gains in front-end web dev, editing, and transformation. We also fixed a bunch of function calling issues that folks have been reporting, it should now be much more reliable. More details in 🧵

What a smart and efficient model. Gemini 2.5 series keep delivering
Gemini 2.5 Flash just dropped. ⚡ As a hybrid reasoning model, you can control how much it ‘thinks’ depending on your 💰 - making it ideal for tasks like building chat apps, extracting data and more. Try an early version in @Google AI Studio → https://t.co/iZJNqQmooH

it’s very easy to gloss over just how hard it is to land models at the frontier that you can also reasonably afford to pay for at scale 2.5 Pro is really something special
