AI Evaluation
A capable open mid-fielder with NVIDIA's ecosystem behind it. The 152 value score is respectable, but GLM-5.2 and DeepSeek define this market's ends and Nemotron sits between them without owning either.
Pros
- Open weights with free serving endpoints
- Solid value (152 on our index)
- NVIDIA NIM ecosystem
Cons
- Mid-pack intelligence (38)
- 512k context trails the 1M leaders
- Overshadowed at both ends of the open market
