It uses a transformer stack with three sliding-window attention layers (4,096-token window each) and one global attention layer. The global layer allows token interaction across the full context of 256K tokens. This hybrid attention design handles local context and long-range dependencies in one request. Tool use and multi-step ReAct agent behavior are core strengths. Command A delivers higher throughput than Command R+ 08-2024 on comparable setups. Structured output, citation generation, safety modes, and RAG are built-in API features rather than prompt-only patterns. The knowledge cutoff is June 2024. Command A covers 23 languages: English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Arabic, Chinese (Mandarin), Russian, Polish, Turkish, Vietnamese, Dutch, Czech, Indonesian, Ukrainian, Romanian, Greek, Hindi, Hebrew, and Persian. This breadth supports multilingual enterprise deployments without separate regional models. See https://docs.cohere.com/v2/docs/command-a for API details. Typical output length is capped at 8K tokens per generation where the API enforces a limit. ## [Copy link to heading](#what-to-consider-when-choosing-a-provider)What To Consider When Choosing a Provider - Configuration: For enterprise deployments across regions or language markets, confirm your provider choice meets data residency needs. Command A lists 23 training languages, so residency and language policy still matter. - Zero Data Retention: Zero Data Retention is offered on a per-provider and model basis. See the [documentation](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) for details. - Authentication: AI Gateway authenticates requests using an [API key](https://vercel.com/docs/ai-gateway/authentication-and-byok#api-key-authentication) or [OIDC token](https://vercel.com/docs/ai-gateway/authentication-and-byok#oidc-token-authentication). You do not need to manage provider credentials directly. ## [Copy link to heading](#when-to-use-command-a)When to Use Command A ### Best for - Multi-step ReAct agents: Tool use and decision chaining spanning many turns - Large-corpus RAG: Context window of 256K tokens fits retrieval results, source documents, and instructions in one prompt - Multilingual applications: Single model covers any of the 23 supported training languages without separate regional variants - Citation workflows: Legal review, regulatory compliance, and research summarization where traceable sourcing is required - High-throughput production: Higher throughput than Command R+ 08-2024 cuts infrastructure cost at scale ### Consider alternatives when - Creative generation focus: Workload centers on open-ended conversation rather than structured enterprise tasks - Reasoning specialist needed: Mathematical or formal logic chains need a reasoning-tuned model - Smaller context suffices: A smaller model would reduce per-token cost at your volume - Unsupported language: Your target language falls outside the 23 supported languages ## [Copy link to heading](#conclusion)Conclusion Command A targets enterprise teams that need an open-weights foundation for agent systems, multilingual deployments, and retrieval-heavy pipelines with unified billing through AI Gateway. It brings a context of 256K tokens, 23-language training coverage, and the throughput gains Cohere cites over Command R+ 08-2024.
