Castor
Mini PC, 64 GB
The Mickai Workstation Castor is a 1 litre obsidian aluminium mini PC built for a single desk, a small office, or a quiet study. It carries the full Sovereign Intelligence Operating System on the box, the cooperative of brains, the Open Audit Record signed under FIPS 204 ML-DSA-65, and the sandboxed upgrade channel. The operator owns the hardware. No subscription for context. No subscription for usage. The price you pay on day one is the price you pay for life. Castor is the mortal twin to Pollux, the 128 GB Mini PC, and the two are sold as a twinned pair where it makes sense.
Castor was one of the Dioscuri, the mortal twin born to Leda, brother to Pollux. The mortal half of a paired set, agile, swift, and inseparable from his brother.

Mickai is held privately by its founder, Micky Irons. One hundred and one UK patent applications have been filed against the substrate, with approximately 2,234 claims across them, on the public UK IPO register under GB2607309.8 onwards. The corpus covers the cooperative architecture, the Open Audit Record, the FIPS 204 ML-DSA-65 signing primitive, the clearance-gated retrieval, the audio dual-layer watermark, the silicon root of trust, and the host-acceptance attestation that lets the Mickai bundle migrate from one machine to another without breaking its signed chain.
Poseidon, the Mickai Sovereign AI SoC. In-house silicon that complements the GPU fabric on every SKU. Carries the OAR signing primitive in silicon, holds the hardware identity and cryptographic root of trust, and sits between the network interface and the GPU fabric so every action that crosses the bus can be policy-checked before commit. Optional on every SKU as the silicon lands.
Pricing TBD. The price on day one is the price for life. No subscription for context or usage. Only paid upgrades through the sandboxed channel, optional.
Launch window: Late 2026
