Chat with a live open model running on attested Apple Silicon. Anonymous, rate-limited, short replies, the same private inference path as the API. When you want full access and longer output, start free: 10M tokens, no card.
Ask anything. This hits the same private inference path as the API.
Anonymous demo · capped output · prompts never logged. How privacy works →
The catalog
The uncensored and community models independent providers host when incumbents will not — per token, one base_url swap.
The privacy
Prompts decrypted in-process on the provider's Mac; the coordinator runs in an attested enclave. Design goal: the operator can't read them (attestation enforcement rolling out during alpha). Threat model →
The alpha
A small live catalog, availability depends on who's online, and Apple Silicon won't match an H100 on 70B. Honest by design.
