Best Websites to Compare AI LLMs in 2025

Top LLM Benchmark Platforms to Know in 2025

Here are the most useful sites for comparing LLM models and tracking new releases this year. Each site has a different focus—covering technical, community, open-source, coding-specific, or even real-world usage benchmarks.

Artificial Analysis

The most rigorous and enterprise-focused leaderboard. Tracks 100+ models, tests intelligence, speed, and price. Covers latest releases immediately. Great for technical, decision-making research.

LLM-Stats

Live rankings and alerts. Tracks updates in real time, with comparisons across context window, speed, price, and general knowledge. Useful for API providers and keeping up with new launches.

Vellum AI Leaderboard

Highlights only the latest SOTA models—no clutter from outdated benchmarks. Specialized in GPQA and AIME scores for reasoning and math. Focused on post-2024 releases.

LMSYS Chatbot Arena

Community-driven, open leaderboard where users vote in blind tests. Large-scale, real-world user ratings for conversational quality. Good for non-technical but practical preferences.

LiveBench

Runs new, contamination-free questions each month. Focuses on fairness and objectivity, especially in reasoning/coding/math tasks. Great for unbiased and evolving model assessment.

Scale AI SEAL

Private, expert-driven benchmarks. Strong on evaluating frontier models, robustness, and complex reasoning. Combines human and automated evaluation.

Hugging Face Open LLM

The open-source leaderboard. Covers only models that can be run independently. Community driven, great for anyone prioritizing open LLMs.

APX Coding LLMs

Specialized for coding tasks and benchmarks. Focuses on programming quality and up-to-date coverage for developer use cases.

OpenRouter Rankings

Real usage stats across dozens of models—all accessible through one API endpoint. See which models are actually used the most (by day, week, or month) for practical popularity and current rankings.

Epoch AI Benchmarks

An interactive dashboard that blends in-house evaluations with curated public data to chart how leading models evolve. Explore trend lines, compare compute budgets, and see how openness and accessibility shape capability gains.
