Scores are percentages reported by model creators or benchmark maintainers under varying settings. A blank is preferable to an inferred result. See our methodology.

Inkling strengths

  • One-million-token maximum
  • Downloadable weights
  • Controllable effort

Inkling limitations

  • Weight license unavailable
  • Numeric API price unavailable
Editorial take: Benchmark rank should narrow a shortlist, not close a purchase. Run a private evaluation with representative prompts, failure cases, latency targets, and total token costs.
