NVIDIA showcases NVFP4 training of Llama 3 on Blackwell with speed gains over FP8

Monday, June 8, 2026Read Original

Details

  • NVIDIA AI reports training Meta's Llama 3 large language models with the new NVFP4 numeric format on the NVIDIA Blackwell GPU platform.
  • Experiments covered both the 8B-parameter and 405B-parameter Llama 3 models, indicating applicability from mid-size to very large frontier models.
  • NVFP4 delivers between 1.31× and 1.73× faster training performance compared with FP8 precision in NVIDIA's measurements.
  • NVIDIA states these speedups are achieved with zero loss in model accuracy relative to FP8, implying no observed degradation in output quality.
  • The announcement highlights NVFP4 as a way to push training efficiency further on Blackwell, beyond existing low-precision formats like FP8.
  • NVIDIA links to additional technical material, likely a blog or paper, for deeper benchmarks and methodology details.

Impact

By demonstrating measurable training speedups for both 8B and 405B Llama 3 models without reported accuracy loss, NVIDIA strengthens the Blackwell platform’s position for large-scale AI training. NVFP4-based gains can lower compute costs and training time, pressuring rival accelerators and signaling continued momentum toward more aggressive low-precision formats in frontier-model development.
