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.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
