Pages that compute an answer instead of describing one. Every number is calculated from the model's real architecture or from a price captured at a stated time — never typed in.
- Cost to run a model →GPU, VRAM and rental price for every open model
- Best GPU for a model →Ranked cards that actually fit
- VRAM calculator →Does it fit? Any model, any card, any context
- Cloud GPU prices →Live per-hour prices, cheapest first
- Can I run it? →Game requirements vs your GPU
- Gadget picks →Curated, honest one-line takes
The Build Kit
16 small interactive explainers used across the learning path— a request's journey, who-can-see-what row security, a context-window meter, a temperature dial, a load simulator and more. Each lesson that uses one offers an embed snippet, so teachers and bloggers can drop the live widget into their own page with a credit link.
