Everything above assumes 4-bit weights and a 8k token context. Going up in precision costs memory; shortening the context is the other lever, and the cheaper one when something almost fits. Model details checked on 2026-08-02.
how to actually run it
what this page will not tell you
How many tokens per second you will get. That is a benchmark — it depends on memory bandwidth, on the engine, on the context and on how long the answers are. This site does not invent benchmarks, and everyone who quotes one for your exact setup is guessing.
