Command R7B (12-2024) ranks higher on the ModelCap Index as of 17 August 2026: #231 against #232. 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.
Command R7B (12-2024) is cheaper on output tokens: $0.15/1M against $8.00/1M. Input tokens are $0.037/1M for Command R7B (12-2024) and $2.00/1M for Sonar Deep Research. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens.
Both publish a 128K-token context window.
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.
Command R7B (12-2024): API only. Sonar Deep Research: 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 Command R7B (12-2024) and 1 for Sonar Deep Research, 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 17 August 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.
