Side-by-side technical and economic comparison between xAI's Grok 2 and Cohere's Command R+ (08-2024).
• Grok 2: Classified as a Legacy Reference model (Generally Available).
• Command R+ (08-2024): Classified as a Legacy Reference model (Tracked Legacy (Predecessor to Command A)).
| Metric | Grok 2 | Command R+ (08-2024) | Advantage |
|---|---|---|---|
| Provider Organization | xAI | Cohere | — |
| Standard Input / 1M | $2.00 | $2.50 | Grok 2 (20% lower) |
| Cached Input / 1M | None | $0.25 | Command R+ (08-2024) lower |
| Output / 1M | $10.00 | $10.00 | Identical |
| Context Window | 128k | 128k | Grok 2 (128k) |
| Max Generation Tokens | 8.2k | 4.1k | Grok 2 |
| Tokenizer Family | xAI Byte-level BPE (~131k vocabulary) | Cohere BPE (~256k vocabulary) | — |
Opt for Grok 2 when your engineering requirements prioritize xAI's ecosystem, specific tokenizer efficiencies (Calibrated xAI Tokenizer (±3%)), or when your expected prompt-to-completion ratios favor its $2/M input rate.
Opt for Command R+ (08-2024) when looking for Cohere's tooling integration, specific context window depth (128k tokens), or when output generation volume favors its $10/M rate.
