Head-to-head comparison

Sonar vs Reka Edge

Sonar (Perplexity) and Reka Edge (Reka) 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 18 August 2026

As of 18 August 2026, Reka Edge holds the stronger ModelCap Index position (#156 vs #196); Reka Edge is 10× cheaper per output token ($0.10/1M vs $1.00/1M); and Sonar offers the longer context window (127K vs 16K tokens).

Which should you choose?

Sonar vs Reka Edge: common questions

Is Sonar better than Reka Edge?

Reka Edge ranks higher on the ModelCap Index as of 18 August 2026: #156 against #196. 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.

Is Sonar cheaper than Reka Edge?

Reka Edge is cheaper on output tokens: $0.10/1M against $1.00/1M. Input tokens are $1.00/1M for Sonar and $0.10/1M for Reka Edge. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens.

Which has the bigger context window, Sonar or Reka Edge?

Sonar has the larger context window: 127K tokens against 16K.

Which is better for coding, Sonar or Reka Edge?

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.

Are Sonar and Reka Edge open-weight models?

Sonar: API only. Reka Edge: Restricted license. Open weights mean the checkpoint can be downloaded and self-hosted under its licence; API-only models are available solely through hosted endpoints.

Where can I run Sonar and Reka Edge?

ModelCap currently lists 1 API provider for Sonar and 1 for Reka Edge, from the OpenRouter catalogue snapshot the site serves; each model page lists the providers and their prices.
