Description
Celeris-1 is an advanced language model developed by Celeris, an AI research lab focused on creating the fastest language models in the world. Designed for ultra-low latency applications, Celeris-1 is ideal for voice, agents, and real-time AI interactions. The model achieves complete answers in just 158 milliseconds with a 75.9% MMLU-Pro accuracy, which can increase to 81.4% with reasoning enabled. This performance is unmatched by other frontier models, which typically take over a second to respond.

Celeris-1 employs a unique diffusion process that begins with a rough representation of the response and refines it into coherent language. This parallel refinement allows the model to operate at unprecedented speeds, making real-time intelligence a reality. The model is particularly suited for applications requiring immediate interaction, such as voice systems, autonomous agents, and AI-driven interfaces that respond at the pace of human input.
The model's capabilities extend beyond traditional architectures, offering developers the tools to build systems that perceive, reason, and act in real time. Celeris-1 has been benchmarked transparently, showing performance within two points of GPT-5 at 15 times lower latency across complete benchmark suites like GSM8K, IFEval, and DROP.
Celeris-1 is designed for developers focusing on ultra-low latency AI systems, providing a new paradigm of inference that changes the possibilities of AI applications. It is a powerful tool for those looking to integrate real-time AI into their projects, offering speed and accuracy that redefine the boundaries of AI technology.
