I've been playing this Code Arena-generated Tetris more than I care to admit 😂 Try it here …ffc-71f6-a578-48e5f195ac5f.arena.site

📊 Leaderboard Ranking Method Update We’ve refined how ranks are displayed to make them more interpretable and statistically accurate. Each model now shows: • Raw Rank: its position by Arena score (no ties) • Rank Spread: the best-to-worst range based on confidence

🚨BREAKING: Google DeepMind’s Gemini-3-Pro is now #1 across all major Arena leaderboards 🥇#1 in Text, Vision, and WebDev - surpassing Grok-4.1, Claude-4.5, and GPT-5 🥇#1 in Coding, Math, Creative Writing, Long Queries, and nearly all occupational leaderboards. Massive gains

🚨🍌BREAKING: Google DeepMind’s Gemini 3 Pro Image aka Nano Banana Pro is in the Arena! Built on Gemini 3, which only two days ago landed as #1 across all major Arena leaderboards. Put it head-to-head in Battle mode with the latest models and judge for yourself if it’s SOTA for

Today, we’re excited to announce our $150M Series A at a $1.7B valuation—nearly 3× our May seed round. Since launching evaluations in Sept, our annualized consumption run rate has surpassed $30M. Our mission is clear: to measure and advance the frontier of AI for real-world use,

Who’s actually leading the AI race? It depends on which leaderboard you look at. On Arena’s Text leaderboard (since May 2023): 🔹OpenAI leads 74% of the time 🔹Google DeepMind 21% 🔹Anthropic 5% But zoom into Expert prompts (~5% of the hardest real-world tasks) and the

🚨BIG NEWS: 🎬 Video Arena is now live on the web! Test out Veo 3.1, Sora 2, Seedance v1.5 Pro, Kling 2.6 Pro, Wan 2.5 & more. What started last summer as a small Discord bot experiment has grown into a rigorous way to measure and understand how frontier video models perform

LMArena is now Arena. A name that takes us back to our roots with a powerful mission: to measure and advance the frontier of AI for real-world use. We have grown from a small PhD research project to a platform powered by a global community of millions. This rebrand has been

👋Say hello to Max! Max is Arena’s intelligent router, powered by 5+ million real-world community votes. Max routes each prompt to the most capable model with latency in mind. AI models excel at different things (code, math, speed, reasoning). Max orchestrates across model

🚨BREAKING: Claude Opus 4.6 by Anthropic is now #1 across Code, Text and Expert Arena! Opus 4.6 shows significant gains across the board: - #1 Code Arena: +106 score vs Opus 4.5 - #1 Text Arena: scoring 1496, +10 vs Gemini 3 Pro - #1 Expert Arena: +~50 lead Congrats to the

The new @xAI Grok-Imagine-Image model is a Pareto-optimal model in Image Arena: The Pareto frontier tells us which model has the highest Arena score at each price point. @xAi’s latest models have improved the frontier, giving optimal performance in the mid-price tier. For a wide

✨NEW: Arena Leaderboard UI Updates Millions of votes power the leaderboard. Now you can filter for what matters to you. A new side panel lets you filter and break down ranked results to find the best model for your task. Some highlights: • Filter by category (e.g. Coding,

⚡️Who powers the Arena leaderboard? You do. But not all votes are Arena level research-grade quality. Every score is built from real-world prompts and human input, continuously refreshed as the way we use AI evolves. In this video, ML Scientist Clayton Thorrez explains how votes are

Today, we’re launching a dedicated Multi-File React leaderboard. When Code Arena first launched, we evaluated models on single-file HTML. Then we raised the bar → multi-file React apps (routing, hooks, components, state management) and now have a leaderboard to match!

Today we’re launching the Video Edit Arena to evaluate the frontier capability of video models! - #1 Grok-Imagine-Video, @xAI - #2 Kling-o3-pro, Kling AI - #3 Kling-o1-pro, Kling AI - #4 Gen4-aleph, @Runwayml The leaderboard is powered by thousands of real-world community

Did you know? We’re funding independent research in AI evaluation and measurement—up to $50k per project. The Q1 deadline to apply for Arena’s Academic Partnerships Program is March 31.

We’ve added Pareto frontier charts to the leaderboard. Now available across: Text, Vision, Search, Document, and Code Arena. The Pareto frontier curve demonstrates which models are most efficient at their level of performance (by Arena score) vs. a blended price per 1M tokens

Exciting news - GPT-Image-2 by OpenAI has claimed the #1 spot across all Image Arena leaderboards! A clean sweep with a record-breaking +242 point lead in Text-to-Image - the largest gap we’ve seen to date. - #1 Text-to-Image (1512), +242 over #2 (Nano-banana-2 with web-search
