LLM Lab — Compare AI models side-by-side

What it does

LLM Lab lets you experiment with multiple large language models side-by-side. Tune parameters like temperature or top-p, test prompts, and instantly compare responses. Ideal for developers, prompt engineers, and AI enthusiasts who want a fast, distraction-free way to benchmark and experiment.

LLM Lab is a powerful testing and comparison platform for language models. Run experiments with multiple LLMs, compare outputs, analyze performance metrics, and optimize parameters like temperature, top_p, and max_tokens. Compare GPT-4, Claude, Gemini, and more.

  I was overspending on GPT-4o. It was really hard to compare different models I could switch to, so I built this LLM comparison tool. It shows leaderboards, pricing, and performance data across 100+ LLMs (including all major providers and open-source models). Key features: - Live pricing comparisons - Benchmark Scores (MMLU, HumanEval, GPQA, etc.) - Context length vs cost analysis - Speed/throughput tests across providers - Quality vs price visualizations - Open source (all data verifiable) Try it out: https://llmstats.com I'd like to know your opinion :) Tech stack: Next.js,…
