DeepSeek V4 Pro
with real privacy
Use the most powerful open-weight model inside ChatLock's encrypted infrastructure. Your prompts encrypted end-to-end, processed inside a secure enclave, never stored.
DeepSeek inside an encrypted enclave
Same model, same capability. But with architectural privacy you can verify — not a promise in the terms of service.
End-to-end encryption
Your prompts are encrypted in your browser before they leave your device. They're only decrypted inside the hardware-secured enclave. No middleman can read them.
Confidential computing
DeepSeek V4 Pro runs inside a Trusted Execution Environment (TEE). Not even ChatLock's infrastructure can observe your data during inference.
Zero data retention
Once your response is delivered, the enclave's memory is wiped. No logs, no copies, no training data. Ever.
Verifiable privacy
Cryptographic attestation lets you independently verify the enclave is genuine and runs the expected code. Don't trust — verify.
What changes with ChatLock
Same open-weight model. Real difference in how your data is handled.
- Your prompts are encrypted end-to-end from browser to secure enclave
- Processing happens inside confidential hardware, not even the operator can observe it
- Zero data retention: nothing is saved, nothing trains future models
- Cryptographic attestation so you verify yourself rather than trusting a policy
