# LMArena review (2026): is it worth it? > Compare AI models side by side and vote on the answers Checked Nov 13, 2026 ยท graded Nov 13, 2026 by ToolGPA. LMArena, now branded Arena at arena.ai, is a platform where you send a prompt to AI models and compare the answers. Your votes feed public leaderboards that rank models for text, web development, images, video, search and other tasks. It started as the UC Berkeley research project Chatbot Arena and is now run by Arena Intelligence Inc. - **Category:** AI Assistants - **Made by:** Arena Intelligence Inc. - **Website:** https://arena.ai - **Runs on:** Web - **Who should skip it:** Skip it if you want a daily assistant with memory and files, as it is built for comparison. - **Facts last checked:** Nov 13, 2026 ## Pricing LMArena's current pricing could not be confirmed from its own site. ## Key features - **Battle mode:** Two anonymous models answer the same prompt and you vote for the better reply. Pre-release models can show up under codenames, according to the FAQ. - **Side by Side and Direct modes:** Side by Side lets you pick two models to compare, and Direct Mode lets you chat with one model of your choice. The FAQ describes how votes are used in each. - **Public leaderboards:** Rankings come from votes using the Bradley-Terry rating system and cover categories such as text, WebDev, vision, document, search, image and video. - **Image and video generation:** The site lists use cases for generating images and videos, with matching text-to-image, image edit and video leaderboards, and a help article on Video Arena. - **Agent and web app building:** The navigation lists an Agent leaderboard and use cases for building apps and websites and completing multi-step tasks. ## Good for - People choosing a model who want to see answers from several side by side - Anyone who wants to try pre-release or newly launched models - Readers who follow community-voted AI rankings ## Worth knowing - The pricing could not be confirmed: the homepage sits behind a bot check and no pricing page exists, so cost and any usage limits are not verified here. - In Battle mode the models are anonymous until you vote, and your votes become part of the public leaderboards. - The terms say an account may be required to access certain features of the service. - The vendor's pages describe a web product and name no desktop or mobile apps. ## ToolGPA grades **GPA: 2.2 out of 4**, graded Nov 13, 2026. LMArena, now branded Arena, lets you send one prompt to AI models and compare the answers, with your votes feeding public leaderboards. But the vendor's pages gave no price, so cost and limits are unverified, and models are anonymous until you vote. - **Value for money: C.** The listing calls it free, but no price page exists and the homepage sits behind a bot check, so the cost is not confirmed. That leaves it in the middle. - **Free plan and trial: C.** Listed as free, but the terms say an account may be required for some features, and no usage limits are published. - **Features: C.** Battle, Side by Side and Direct modes, leaderboards, image and video generation. A focused tool for comparing models, not a daily assistant. - **Ease of use: B.** A website where you type a prompt and pick the better answer. No store rating is on record. - **Platforms and integrations: C.** Web only. The pages name no apps and no integrations. These are ToolGPA's own grades. Graded from this listing, whose facts were read from LMArena's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. Its pricing page showed no plan prices in the text we could read, so the grades lean on the listing. ## Where it stands among AI assistants - LMArena's GPA of 2.2 is higher than 15 of the 87 other AI assistants we grade, and level with 15. - It stands best on ease of use (B, above 40 of 87) and worst on features (C, above 1). - LMArena has no paid plan. - On features, ease of use and platforms it scores 2.3 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.

And it is not the kind of software a weekend replaces. That makes this kind of software worth paying for, not this one in particular: 57 of the 87 other AI assistants grade higher. - You could not: An AI model, which you can rent by the request but not make. - You could not: An image model, which you can rent by the picture but not make. - You could not: A video model, which you can rent by the second but not make. - You could not: A search engine with an AI model behind it.
