Nemotron 3.5 Lightning vs Particle-1: which should you choose in 2026?

Nemotron 3.5 Lightning (by NVIDIA) and Particle-1 (by Particle ai) are compared below. Here is how they stack up on benchmarks, price, and capabilities, and which one to pick in 2026.

There are not enough shared, protocol-compatible benchmark results to declare a performance leader.

Nemotron 3.5 Lightning is about 1.6× cheaper on a blended 3:1 input/output basis ($0.1025 vs $0.1625 per 1M tokens).

Particle-1 has the larger context window (1,048,576 tokens vs 262,144 tokens).

Choose Nemotron 3.5 Lightning if…

  • • lower blended API cost matters for your workload

Choose Particle-1 if…

  • • you work with longer documents, transcripts, or codebases
  • • you need image inputs

The benchmark count includes only results measured with a matching benchmark version and protocol. Arena scores are shown separately. Missing, preliminary, and incompatible data is not treated as a controlled win. Published point-score comparisons are labeled separately when protocol details are incomplete. For text-output models, the verdict also compares token pricing and context windows.
