VRAM, throughput and GPU cost calculators plus courses for open-weight LLM deployment
Estimates weight and KV cache memory for a chosen model variant, context length, batch size and quantization so you know whether a GPU will actually fit the workload.
Projects time-to-first-token and tokens-per-second throughput per hardware configuration to help you size for real user traffic.
Converts memory and performance estimates into hourly and per-token economics across hardware configurations.
Reference pages for 500+ model variants and documented hardware benchmarks, keeping sizing inputs in one place.

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.
