Phala has announced the integration of its confidential AI infrastructure into the OLLM Confidential AI Gateway. This development allows developers to access hardware-secured AI models with cryptographic privacy guarantees through a simple API call. The integration aims to enhance privacy and security for AI applications by leveraging Phala’s private AI cloud.

Phala’s infrastructure operates within hardware Trusted Execution Environments (TEEs) from Intel TDX, AMD SEV, and Nvidia H100/H200 GPUs. This setup ensures that code, data, and model weights remain encrypted during execution, protecting sensitive information from unauthorized access, including by cloud providers. Unlike traditional AI platforms, Phala offers verifiable privacy through cryptographic attestation, which proves that workloads ran on genuine TEE hardware. Users can verify these proofs via Phala’s Trust Center, ensuring data confidentiality throughout processing.

Production-Ready Confidential AI

The partnership with OLLM makes Phala’s confidential computing infrastructure accessible to developers building privacy-critical AI applications. Through OLLM’s gateway, teams can run advanced models on Nvidia H200 GPUs with Intel TDX and AMD SEV protection, experiencing only a minimal performance overhead of 0.5% to 5%.

Real-world applications of this technology span various sectors, including financial services, healthcare, Web3, and enterprise solutions. For instance, financial services can process sensitive transaction data securely, while healthcare providers can analyze patient records while maintaining compliance with regulations like HIPAA. In the Web3 space, on-chain analytics can be conducted without exposing user identities, and enterprises can deploy AI agents that handle proprietary data confidentially.

Why Hardware Security Matters

Traditional cloud AI services often process data in plaintext, requiring users to trust the provider. Phala’s architecture eliminates this trust requirement by creating isolated, encrypted environments for model execution using Intel TDX and AMD SEV. Nvidia H200 GPUs further enhance performance for large language models, while cryptographic attestation verifies that workloads ran inside genuine TEE hardware. This ensures that data remains encrypted from input to output, with no plaintext exposure.

Ahmad Shadid, CEO of OLLM, emphasized the importance of this integration, stating, “Enterprises want the benefits of modern AI, but they cannot compromise on data confidentiality or control.” The integration with Phala’s confidential AI cloud provides a straightforward way for developers to access hardware-secured models with verifiable privacy.

Why This Matters: Impact, Industry Trends & Expert Insights

Phala’s integration of confidential AI infrastructure with the OLLM Gateway allows developers to access secure AI models with cryptographic privacy, enhancing privacy and security for AI applications.

Recent industry reports indicate that confidential computing is becoming a foundational enabler for AI, with over 75% of untrusted infrastructure processing expected to use it by 2029. This aligns with Phala’s integration, which leverages hardware-based trusted execution environments to protect sensitive data during AI processing.

As per insights from Duality Tech, TEEs like Intel SGX, AMD SEV-SNP, and Arm TrustZone enhance security via attestation, making GPU TEEs from NVIDIA the ‘next frontier’ for secure AI in regulated sectors. This supports the significance of Phala’s integration, which provides verifiable privacy and security for AI applications.
