Summary
The creator reacts to NVIDIA's launch of Nemotron 3.5 Lightning. It is an open 30B mixture-of-experts model with only 3B parameters active per token, built for always-on agents doing high-volume, specialized tasks. A useful example of why small-active-parameter MoE models are picked for agent workloads where speed matters.
Key points
- Nemotron 3.5 Lightning is an open 30B-parameter MoE model with 3B active parameters.
- It is designed for always-on agents running high-volume, specialized tasks.
- NVIDIA claims up to 4x the output speed of similar-sized models.
- Few active parameters means cheaper, faster inference while total capacity stays large.
