LM Arena Side-by-Side Se Models Compare Karein

lmarena.ai aur arena.ai ab ek hi site hain — "Arena AI", AI models ka sabse bada free public ranking platform. Iska LM Arena side-by-side mode aapko do models ko aamne-saamne, ek hi prompt par, bina kisi paisa ke compare karne deta hai. Ye walkthrough official how-it-works, FAQ aur homepage (sab 23 September 2026 ko live check) se banaya gaya hai.

LM Arena ab kya hai — rebrand jo log miss karte hain

LMArena (LMSYS se nikla Chatbot Arena) ab Arena Intelligence ke naam se chalta hai, aur dono domains lmarena.ai + arena.ai same product serve karte hain — page title "Arena AI: The Official AI Ranking & LLM Leaderboard". Scale numbers company ke apne 29 June 2026 ke post se: 10 million+ monthly users, 700 million+ conversations, 82 million+ votes, aur launch ke 8 mahine mein $100M annualized revenue — sab isliye ki labs ko human preference data chahiye.

Ye koi marketing benchmark nahi: leaderboard Bradley-Terry rating system par chalta hai (chess jaisa Elo, paired comparison ke liye banaya gaya) — lakhs real votes se, jo open research datasets (HuggingFace) par public hote hain. Isi data se Chatbot Arena (ICML 2024), Arena-Hard, RouteLLM jaise papers nikle hain.

LM Arena side-by-side: free compare karne ke exact steps

1. Site kholo: arena.ai (ya purana lmarena.ai — dono same jagah jaate hain). Leaderboard, How-it-works aur FAQ sab bina login ke public hain.
2. Mode chuno: Homepage par Chat → Compare Models Side by Side wala option hai. (Confusion mat khao — "Battle" alag mode hai, niche diye table mein farak hai.)
3. Do models select karo: Side-by-side mein aap khud specific models chunte ho — dropdown se do alag models (jaise ek frontier + ek sasta) pick karo.
4. Ek hi prompt dono ko bhejo: Same prompt, same conversation structure — dono taraf ke answers aamne-saamne milte hain. Image/video/webdev ke liye upar wale icon se mode badlo (image icon → image generation, wagarah).
5. Judge + vote (optional): Side-by-side mein vote kar sakte ho — lekin dhyan: ye votes leaderboard mein count nahi hote (wo sirf anonymous Battle votes ke hain). Aapka choice research ke liye collect hota hai.

Ek honest note: public pages sab open hain, lekin chat/battle flow aapke session mein sign-in prompt dikha sakta hai (Google login). Signup free hai — koi paid plan nahi chahiye — par "bina login ke chat" wala claim har jagah same nahi chalta; apne browser mein jo dikhe wahi asli hai.

Compare karte waqt ek kaam accha rehta hai: ek hi concrete prompt dobara mat chalao — pehle ek simple summarization, phir ek coding task, phir ek reasoning puzzle har round mein do. Ek prompt par do models ka result coincidence ho sakta hai; teen alag tarah ke prompts ka pattern hi asli difference dikhata hai. Homepage ke preset prompts (landing page, dashboard, browser game wagarah) Code Arena ke liye ready-made starting points hain.

Battle vs Side-by-Side vs Direct: teeno modes ka farak

Battle ke teen subtle rules jo FAQ mein likhe hain: (1) har vote ke baad models dobara anonymously resample hote hain — same chat mein bhi; (2) vote ke baad jo votes aate hain unka leaderboard par asar nahi; (3) codenamed pre-release models bhi dikhte hain — labs launch se pehle variants yahan test karti hain, pass hone par official naam se rank mil jaati hai.

Leaderboard kaise padhein

arena.ai/leaderboard par ab 12 categories hain: Agent, Overall, Text, WebDev, Image-to-WebDev, Text-to-Image, Image Edit, Text-to-Video, Image-to-Video, Video Edit, Vision aur Document Search. Do updates ise 2026 mein zyada useful banate hain:

• AutoEval (30 July 2026): jab human votes abhi accumulate nahi hue, platform AI-calibrated ratings deta hai — naye models par "score" dikhe toh ye background zaroor samajh lo.
• Factuality leaderboard (14 July 2026): sirf preference nahi, factual accuracy bhi alag rank hoti hai — "sabse liked" aur "sabse sahi" alag cheezein hain.

Score dekhte waqt style control ka dhyan rakho — FAQ ke mutabik system response style bias ko bhi control karta hai, taaki "sundar jawab" wala model sirf isi se rank na le aaye.

Free access aur data: do caution

Free? Haan — koi paid tier nahi hai chat compare ke liye, aur FAQ kehti hai "as many prompts and votes as you'd like" — rate limits normal users ke liye khule hain. Platform ka khud ka paisa enterprise evaluations + labs se aata hai, user se nahi.

Data? Yahan dhyan chahiye: tumhare prompts public research datasets aur model providers ke paas (de-identified) share ho sakte hain; homepage ka banner seedha kehta hai "Inputs are processed by third-party AI". Matlab: yahan confidential code, client data ya personal details mat paste kariye — testing prompts, drafts, creative work ke liye perfect hai.

Ek recap line: side-by-side = aapke do chune hue models (free, vote leaderboard nahi jaata); Battle = anonymous matchup (vote count hota hai); leaderboard = 12 categories + Bradley-Terry. Bas yahi teen cheezein samajh lo, aur Arena ka poora fayda utha lo — paise zero, bias kam.
