Zyphra AI is a company focused on AI research and product development that builds full‑stack open‑source technologies for advanced intelligence. Its offerings span foundation models, an inference platform, and agent systems.
Key products include foundation models such as ZAYA, ZONOS and ZUNA; the Zyphra Inference Cloud; the multimodal agent system Maia; the integrated Z.ai platform; and the ZONOS voice cloning tool.
Per published releases, some models—such as the ZONOS audio model—are open‑sourced under the Apache 2.0 license. Other models and techniques (for example, Tree Attention) also have open‑source code published.
ZONOS is a high‑fidelity AI voice cloning tool. Users upload audio samples through the platform to generate cloned voices, suitable for content creation and related use cases.
Zyphra Inference Cloud supports leading open‑source models (for example DeepSeek, Kimi, Qwen) as well as Zyphra’s in‑house models, providing high‑throughput, low‑latency distributed inference services.
ZUNA is a foundation model specialized for EEG data. Its core functions include denoising, signal reconstruction and upsampling, aimed at advancing non‑invasive brain‑computer interface research.
Tree Attention is an efficient optimization for long‑sequence inference: its communication efficiency grows logarithmically with GPU count, improving speed and reducing memory usage on long sequences while preserving computation accuracy.
Yes. Developers can access open‑source models and code, and use the Z.ai platform to experience features, obtain development tools, and prototype or test AI applications.
Cerebras provides industry-leading wafer-scale AI compute infrastructure, powered by its unique WSE chip, delivering performance and efficiency far beyond traditional hardware for training large-scale language models and fast inference.

Jina AI is a platform that provides enterprise-grade multimodal and multilingual search solutions. By leveraging neural search technology and Retrieval-Augmented Generation (RAG) workflows, it helps developers and businesses build efficient, precise intelligent search applications.
