Arcium launches Blackthorn private AI inference stack in alpha
- —Blackthorn's private alpha opened on October 21, 2026
- —Prompts, model weights and outputs are encrypted end to end
- —MPC replaces CPU TEEs, opening access to roughly 5 million NVIDIA GPUs
- —Arcium's network had processed over 1 million confidential computations before launch
Why it matters: Private inference lets AI models handle sensitive healthcare, finance and legal data without exposing prompts or proprietary weights.
