Complexity in model modes shows why verifiable AI matters. You're not forced to trust the label, because cryptography proves which model was used, and that it executed correctly. That's what we're building at Polyhedra.
In trying to make it simpler, I fear OpenAI has made it more confusing to understand what model you’re using. In ChatGPT there are now different models you can select than the ones available in the API, and it’s not clear which ones map to which. Is “ChatGPT-5 Thinking” GPT-5.

2/.Why zkGPT matters:. - Stops providers from downgrading models secretly. - Enables regulator-ready AI. - Protects model IP with proof-as-watermark. - Unlocks trust for enterprises & high-stakes use cases.

AI is moving fast but trust hasn’t kept up. On the Polyhedra Show with @jiahengzhang96, @sampearton and @Tony0kAI, we introduced zkGPT: a framework to prove LLM outputs are real with zero-knowledge proofs. What we learned 🧵👇.

Last week, we shipped powerful upgrades to Expander:. - CUDA 13.0 compatibility fix for Fiat-Shamir.- Shared memory optimization → 1 TB/s bandwidth.- 9000 zk proofs/sec achieved on m31ext3.- MSM accelerated on GPU for KZG commitments. zkML’s backbone just got stronger.

.@RashadMirza404 asking the important questions. In our zkGPT research paper, we show how providers can cryptographically prove they’re running the claimed model without leaking their secret sauce. We shouldn’t have to rely on blind trust, even with @OpenAI.

5/ Next step: run the GPU-powered proving system in production-like environments and continue refining the FaceID flow for onchain authentication. We are closing the gap between concept and production for human-first onchain verification. Stay tuned.

4/ Shipping improvements more efficiently. We are setting up deployment of the FaceID server on Cloud Run with continuous integration and deployment so updates can move into production more quickly and reliably.

3/ FaceID now better reflects how it will be used in practice. We modified the API and server logic to align with real-world usage patterns, ensuring the design matches the needs of actual onchain applications.

Let’s break it down 🧵 👇. 2/ Faster proofs mean a smoother user experience. We tested open-source implementations of Multi-Scalar Multiplication (MSM) on GPU and integrated them into the Expander proving system. This strengthens the foundation for scaling our cryptographic.
