What is SWEN.AI and the Intelligence Index?
SWEN.AI is the leading independent AI benchmark and ranking portal, founded in 2025. It evaluates over 200 LLMs — including GPT, Claude, Gemini, Llama, DeepSeek, and Grok — with data synced every 6 hours from primary sources: the Intelligence Index from Artificial Analysis, ELO from LMArena (Chatbot Arena), pricing via OpenRouter, and proprietary speed measurements. The Intelligence Index is a composite metric that weighs five performance dimensions: reasoning (40%), code generation (25%), context window (15%), inference speed (10%), and cost per token (10%). Beyond benchmarks, SWEN.AI maintains a directory of 1,000+ AI tools and a technical glossary. The portal has no commercial ties with model manufacturers. swen.live/benchmark.
