In this paper we propose an 8-bit floating point (FP8) binary interchange format consisting of two encodings - E4M3 (4-bit exponent and 3-bit mantissa) and E5M2 (5-bit exponent and 2-bit mantissa). While E5M2 follows IEEE 754 conventions for representatio of special values, E4M3’s dynamic range is extended by not representing infinities and having only one mantissa bit-pattern for NaNs. We demonstrate the efficacy of the FP8 format on a variety of image and language tasks, effectively matching the result quality achieved by 16-bit training sessions...."},{"url":"https://lightning.ai/pages/blog/8-bit-quantization-with-lightning-fabric/","final_url":"https://lightning.ai/pages/blog/8-bit-quantization-with-lightning-fabric/","title":"8-bit Quantization with Lightning Fabric","http_status":200,"content_type":"text/html; charset=UTF-8","capture_method":"plain","fetched_at":"2026-06-07T21:16:38.400074+00:00","bytes":36961,"raw_path":"c814a8cdd97d871df2c7d957c229631c980e9083828e9d651b7883dc78ccee12.html","content_hash":"2cfbfba9f82e9eadf1fdc8642f5d25bab440fbead5f9ea2c6f94a40f3c2328cd","excerpt_chars":1200,"truncated":true,"excerpt":"8-bit Quantization with Lightning Fabric - Lightning AI Lightning AI Studios: Never set up a local environment again → Takeaways Readers will learn the basics of Lightning Fabric’s plugin for 8-bit quantization.
