Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Free LLM toolkit: cost calculators, prompts and model comparison
Estimate API costs for GPT-4, Claude, Gemini and 25+ models and compare pricing across providers before you spend.
Access a large library of ready-made prompts and count tokens for any model to reduce cost and improve efficiency.
Find the best model for a use case and compare MMLU, HumanEval and other performance metrics interactively.
Chat with several AI models at once for side-by-side comparison, and upload PDFs or Word files to query them with AI.
