What is Phala Cloud?
Phala Cloud is a decentralized confidential computing platform that allows developers to deploy AI applications with hardware-enforced privacy guarantees.
The platform uses Trusted Execution Environments on both CPU and GPU to ensure that sensitive data and AI models remain private during processing, preventing unauthorized access even from the infrastructure provider.
Blockchain-secured key management adds an additional layer of cryptographic assurance that complements the hardware security measures.
The platform targets AI developers, enterprises in regulated industries, and organizations deploying AI agents or models that process sensitive data.
A healthcare organization running AI inference on patient-adjacent data, a financial institution using AI for proprietary trading models, or a developer building AI agents that handle private user information can use Phala Cloud to ensure that the underlying compute infrastructure cannot access the data or model weights during processing.
This addresses the fundamental trust problem in cloud AI deployment where the cloud provider has potential access to everything running on their hardware.
Phala Cloud supports popular AI frameworks including TensorFlow, PyTorch, and Hugging Face, allowing developers to run existing models with enhanced security without rewriting their inference code. The platform offers both CPU and GPU deployment options with optimized compute configurations for AI workloads.
The confidential computing approach adds only 5 to 10 percent overhead compared to standard AI deployments, making the privacy guarantee practical for production workloads where performance matters.

Frequently Asked Questions
What is confidential computing and how does Phala Cloud use it for AI?
Confidential computing uses hardware-based Trusted Execution Environments to isolate and protect data and code during processing. Even the infrastructure provider cannot access data while it is being processed inside a TEE. Phala Cloud implements TEE on both CPU and GPU hardware, combined with blockchain-secured key management, to ensure that AI models and the data they process remain private throughout inference. The overhead compared to standard AI deployment is 5 to 10 percent.
What AI frameworks and models does Phala Cloud support?
Phala Cloud supports TensorFlow, PyTorch, Hugging Face, and other major AI frameworks. Developers can deploy existing models without rewriting inference code for the confidential computing environment. The platform provides CPU and GPU TEE deployment options, allowing teams to choose the compute configuration appropriate for their workload size and latency requirements.
How much does Phala Cloud cost and how does pricing work?
Phala Cloud uses usage-based pricing with no subscription fees, setup costs, or vendor lock-in charges. GPU TEE instances start at $0.50 per hour. New users receive $20 in free credits and one free CVM instance to evaluate the platform. Organizations pay only for active workloads, making the platform practical for both development evaluation and variable production workloads.
What compliance certifications does Phala Cloud hold?
Phala Cloud holds SOC 2 Type I certification and is HIPAA compliant. ISO 27001 certification is in progress. These certifications make the platform viable for regulated industries including healthcare and finance that require documented security compliance credentials from their AI infrastructure providers, not just technical assurances.
How does Phala Cloud differ from standard cloud AI deployment on AWS or GCP?
Standard cloud AI deployment on AWS or GCP requires trusting that the cloud provider will not access your data or model weights, and the provider has technical capability to do so. Phala Cloud uses hardware TEE to make that access cryptographically impossible even for the infrastructure provider. Phala also eliminates single-provider lock-in through its decentralized multi-cloud architecture. GCP offers confidential VMs as a comparison point, but Phala's open-source, decentralized approach provides additional assurances that centralized proprietary implementations cannot.
