CHAI – AI Lab Quantizes Social AI to 4-bit for +56% Increase in Throughput

CHAI, the high-growth AI startup, unveiled a major advancement in model optimization through its successful deployment of quantized large language models (LLMs). The breakthrough—achieved by CHAI’s AI research team—reduces inference latency by 56% while preserving model performance, a critical milestone as the platform now serves 1.2 trillion tokens daily, rivaling industry giants like Anthropic’s Claude.

Model quantization, a technique that reduces the numerical precision of neural network parameters, has emerged as a key strategy for optimizing LLMs. CHAI’s research team systematically evaluated multiple quantization approaches (including INT8, FP16, and hybrid methods) to maximize efficiency without sacrificing output quality. The winning implementation:

Sponsored
• 56% faster inference – Dramatically reduces response times for end users
• smaller model footprint – Lowers memory and compute costs
• – Maintains accuracy across benchmarks

The quantized model deployment complements CHAI’s $20 million compute investment, addressing the platform’s exponential growth. By marrying hardware scaling with algorithmic innovation, CHAI now serves 1.2T tokens per day while maintaining competitive inference speeds.
