open model

DeepSeek has released V4 Flash Vision Exp, an experimental vision-enabled variant of DeepSeek V4 Flash 0731 that adds image understanding while matching the base model's text performance. The sparse mixture-of-experts model uses 13B active parameters out of 284B total and supports a 1M token context window.

NVIDIA's Nemotron 3.5 Lightning, a 30B-parameter hybrid Mixture-of-Experts model with only 3B active parameters, is now available for one-click deployment on Amazon SageMaker JumpStart. NVIDIA claims up to 4x higher throughput and 30% faster task completion for high-volume agentic workloads compared to larger frontier models.
