Search models that run on 256 GB
8 models with published weights that fit in 256 GB — a Mac Studio with 256. Counted at four-bit quantisation, weights only, leaving the machine about a third of its memory and a gigabyte for context: room for roughly 274 billion parameters. A mixture of experts is counted in full, because it is held in full even though only a few experts compute.
A Mac Studio at the top of its configuration, or a serious machine. Almost everything openly published fits, including the large mixtures of experts. At this point the constraint is no longer whether the model loads but whether it generates fast enough to be worth waiting for.
Models, tools and agents that go and look something up — the open web, a set of documents, a grounded answer with citations. Pricing is usually per call or per result rather than per token, so the cost follows how often you ask. What differs is freshness, how much of each page you get back, and whether you are handed sources you can check or a summary you must trust.
