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 🧵
Introducing Gemini 3 ✨ It’s the best model in the world for multimodal understanding, and our most powerful agentic + vibe coding model yet. Gemini 3 can bring any idea to life, quickly grasping context and intent so you can get what you need with less prompting. Find Gemini 3 Pro rolling out today in the @Geminiapp and AI Mode in Search. For developers, build with it now in @GoogleAIStudio and Vertex AI. Excited for you to try it!
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 ↓
LLMs for IMO 2025: gemini-2.5-pro (31.55%), o3 high (16.67%), Grok 4 (11.90%). matharena.ai

Introducing the Gemini 2.5 model family: - Gemini 2.5 Pro (Stable, no changes from 06-05) - Gemini 2.5 Flash (Stable, updated pricing from 05-20) - Gemini 2.5 Flash-Lite (Preview, small reasoning model) More info in 🧵
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 previous regressions but delivers significant improvements across our independent benchmarks. Key highlights: ➤ #1 Position across evals: Gemini 2.5 Pro (June) now leads across a range of evals including MMLU-Pro (86%), GPQA Diamond (84%), Humanity's Last Exam (21%) ➤ Leading coding performance: 80% on LiveCodeBench, matching o4-mini (high) ➤ Variable reasoning budget: Users can vary the maximum amount of output tokens that can be used for ‘thinking’, allocating more tokens as needed for harder tasks Gemini 2.5 Pro retains Google's signature capabilities: ➤ Ultra-long 1 million token context window ➤ Multimodal inputs: image, video, and audio support (text output only)
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 heard your feedback and made improvements to style and the structure of responses. Try it in AI Studio, Vertex AI, and @Geminiapp. GA coming soon!
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.
