Zama Product Releases - January 2025

This month, our team at Zama released a new version of TFHE-rs (v0.11), alongside new versions of Concrete (v2.9), Concrete ML (v1.8) and the fhEVM (v0.6) featuring the fhEVM Coprocessor. With these releases, Zama continues to build its suite of products to make homomorphic encryption accessible, easy, and fast.

TFHE-rs v0.11

This new version of Zama's TFHE-rs brings several major improvements and new features. TFHE-rs v0.11 introduces significantly enhanced performance for Zero Knowledge Proofs and a new module for encrypted strings usable in the High Level API via the [.c-inline-code]FheAsciiString[.c-inline-code] type. Besides, default cryptographic parameters now follow a tweaked uniform (TUniform) noise distribution instead of a Gaussian one. GPU performance has also been improved: the 64 bit addition is 30% faster compared to v0.8. Finally, it is now possible to perform computations on arrays of ciphertexts easily on GPU.

Concrete ML v1.8

This new version of Zama’s Concrete ML marks a major step in enabling privacy-preserving fine-tuning for Large Language Models (LLMs). Concrete ML v1.8 improves the speed and usability of LLM hybrid fine-tuning with an optimized FHE backend specific to LLMs and a new Low Rank Approximation API. Additionally, Concrete ML v1.8 now supports Python 3.12, ensuring compatibility with the latest tools and frameworks.

fhEVM v0.6

This new version of Zama's fhEVM introduces expanded type support, a more robust input mechanism with proof capabilities, and enhanced configurability for fhEVM deployment. These changes continue to improve flexibility, usability, and integration with encrypted data systems. The fhEVM v0.6 also comes with one of Zama’s most exciting innovation so far: the fhEVM Coprocessor. Developers can now build confidential smart contracts on any EVM chain.
