Head-to-head comparison
Nova Micro 1.0 (Amazon) and Sonar (Perplexity) compared on the ModelCap Index, API price, context window, provider availability, weight access and every public benchmark board they share. Figures are the same ones shown on the live rankings; nothing here is a hidden score.
Snapshot as of 3 September 2026
As of 3 September 2026, Sonar holds the stronger ModelCap Index position (#200 vs #201); Nova Micro 1.0 is 7.1× cheaper per output token ($0.14/1M vs $1.00/1M); and Nova Micro 1.0 offers the longer context window (128K vs 127K tokens).
Evidence: 2 public benchmark observations across 2 boards · 1 public benchmark observation across 1 board. Prices are the lowest listed API offer per million tokens observed on the OpenRouter catalogue.
Scores are the sources' own published figures for each model's best evaluated configuration; ModelCap never re-runs a benchmark.

Sonar ranks higher on the ModelCap Index as of 3 September 2026: #200 against #201. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it.
Nova Micro 1.0 is cheaper on output tokens: $0.14/1M against $1.00/1M. Input tokens are $0.035/1M for Nova Micro 1.0 and $1.00/1M for Sonar. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens.
Nova Micro 1.0 has the larger context window: 128K tokens against 127K.
The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.
Nova Micro 1.0: API only. Sonar: API only. Open weights mean the checkpoint can be downloaded and self-hosted under its licence; API-only models are available solely through hosted endpoints.
ModelCap currently lists 1 API provider for Nova Micro 1.0 and 1 for Sonar, from the OpenRouter catalogue snapshot the site serves; each model page lists the providers and their prices.
Every figure comes from the sealed ModelCap dataset published 3 September 2026; the page re-renders within a minute of each data refresh, and the ModelCap Index positions are the same ones shown on the live rankings.
