Arena (Free) added to the directory

Arena (Free), the free anonymous multi-model chat and blind A/B voting service behind the public LLM, image, and code leaderboards at arena.ai (formerly LMArena/Chatbot Arena), has been added to the Uprouter provider directory as an unofficial web-cookie integration. Uprouter rates Arena (Free) as medium risk, noting that automated access relies on the arena-auth cookie plus optional Cloudflare cf_clearance/__cf_bm and reCAPTCHA tokens, is rate-limited and subject to bot checks, and may put accounts at risk because arena.ai's terms are aimed at human benchmarking. Arena (Free) publishes no per-1M-token pricing and has no paid tiers, and the directory lists the rotating lineup including gpt-5 (400k context), claude-sonnet-4-6 (1M), gemini-3.1-pro-preview (1.0M), and Grok 4.3 (1M).
