About Redpill
Redpill is a confidential AI inference aggregation gateway running inside trusted execution environments and compatible with the OpenAI and Anthropic APIs. Requests pass through a gateway deployed in Intel TDX and route to GPU trusted environments at Phala, Tinfoil, NEAR AI and Chutes; every response carries remote attestation and a signed receipt, the gateway stores neither prompts nor completions, and the catalogue includes unfiltered models. The pain point is that privacy on ordinary cloud inference rests on policy promises, prompts may be retained or used for training, and attestation formats differ across trusted-environment providers.
It added Qwen3.8 27B on 24 August 2026, GLM 5.3 on 31 August, Nemotron 3.5 on 11 September, an unfiltered Qwen3.8 on 16 September and Kev 4B on 13 October; on 15 September the codebase was refactored into a unified gateway architecture.
Redpill has made significant progress in the private AI gateway space over the past six months. The project now aggregates 60+ models across four TEE providers (Phala, NearAI, Chutes, Tinfoil), all running on Intel TDX + NVIDIA CC hardware. Key developments include: (1) a unified OpenAI-compatible API requiring only a base URL change for migration; (2) smart routing that optimizes for availability, price, or end-to-end encrypted paths, with private mode never downgrading to non-TEE fallbacks; (3) virtual keys (sk-rp-*) with per-key budgets and rate limits; (4) E2EE v2 using AES-256-GCM with secp256k1 key exchange and nonce binding; (5) a verifier tool (redpill-verifier npm package) supporting light mode (no Docker) and deep mode (Intel attestation via dstack-verifier), with on-chain verification on Sepolia and Automata Mainnet. The roadmap focuses on expanding verified provider coverage, deepening audit session capabilities with signed receipts, and growing the developer-first ecosystem around the gateway API.
