Method note: the global score is the mean of the seven category averages, computed by us from LiveBench's published file; it may differ by a few decimals from the site's own display. Equal scores keep LiveBench's file order. Benchmarks measure benchmark tasks — during an AI diagnostic we re-run the comparison on your own workloads.
Running claude-haiku-5-5-xhigh-effort with BrainOutput
BrainOutput routes each task to a model by confidentiality: sensitive work stays on a local or private model, and everything else goes to a cloud model only when your policy allows it.
Locally, on your hardware
Checked at diagnostic
Possible only if the weights are published: we verify the licence during the AI diagnostic, before any deployment.
In a private cloud
Checked at diagnostic
Possible only if the weights are published — verified during the AI diagnostic.
With your own key (BYOK)
Available
Plug in your own Anthropic API key: BrainOutput routes non-sensitive work to it when your policy allows; sensitive work never leaves your perimeter.
