Named machines
Try models on real Apple-silicon classes instead of abstract benchmark rows.
00 / Real Macs. Real models.
BitterMill lets you use serious open models on real Apple-silicon machines before you buy hardware, move a workload local, or trust a benchmark table.
Choose a machine. Load a model. Decide from experience.
Try models on real Apple-silicon classes instead of abstract benchmark rows.
See cold starts, warm starts, queueing, and responsiveness instead of just a tokens-per-second claim.
Pay separately for model load, warm hold, and generation so the tradeoffs stay legible.
Run it live
Use it directly instead of inferring quality from other people’s charts.
Compare classes
Run the same model across different machines and feel the difference in load, headroom, and rhythm.
Keep it warm
Warm sessions, cold starts, and priority all feel different. BitterMill treats them differently.
Available now
64 GB unified memory
The practical desktop test: how far can a serious Mac go before you need more memory or a different class of machine?
Available now
128 GB unified memory
The high-headroom test: best for larger open models, more ambitious workloads, and finding out what happens when memory stops being the first limit.
Coming next
The fleet expands over time, so you can test more of the Apple-silicon range without owning every machine yourself.
BitterMill separates setup cost from runtime cost so the economics stay legible.
Load
Spin up the model you want on the machine you chose.
Warm hold
Keep a useful model resident when low latency matters.
Generation
Pay for the actual run, not for folklore around the infrastructure.
Priority
Move faster when you need guaranteed attention from scarce machine memory.
