Side-by-side technical and economic comparison between xAI's Grok 2 mini and Cohere's Command A.
• Grok 2 mini: Classified as a Legacy Reference model (Generally Available).
| Metric | Grok 2 mini | Command A | Advantage |
|---|---|---|---|
| Provider Organization | xAI | Cohere | — |
| Standard Input / 1M | $0.20 | $2.00 | Grok 2 mini (90% lower) |
| Cached Input / 1M | None | $0.20 | Command A lower |
| Output / 1M | $1.00 | $8.00 | Grok 2 mini lower |
| Context Window | 128k | 256k | Command A (256k) |
| Max Generation Tokens | 8.2k | 64k | Command A |
| Tokenizer Family | xAI Byte-level BPE (~131k vocabulary) | Cohere Byte-Pair Encoding (256k vocabulary) | — |
Opt for Grok 2 mini 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 $0.2/M input rate.
Opt for Command A when looking for Cohere's tooling integration, specific context window depth (256k tokens), or when output generation volume favors its $8/M rate.
