NVIDIA Nemotron 3.5 Lightning and Switchyard
- Third-party evaluations published August 15 found Nemotron 3.5 Lightning, an NVIDIA mixture-of-experts model released August 11, at 296.7 tokens per second and an Artificial Analysis Intelligence Index of 24, both above open-weight medians, but trailing Qwen3.6 35B and Gemma 4 26B on NVIDIA's long-context benchmark.
- A Cognition case study showed NeMo Switchyard, NVIDIA's routing library, cutting mean cost 28% between Opus 5 and Kimi K2.7, while a Wavect review concluded version 0.2 is not production-ready due to documented gaps.
The external benchmarks give developers a clearer picture than NVIDIA's own figures: the model delivers strong inference speed but falls short on long-context comprehension, and the routing library shows real cost reductions in partner deployments while carrying acknowledged maturity gaps in version 0.2.
