Frequently Asked Questions

Is Command R+ cheaper than o3?

At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), o3 costs $600.00/month versus $750.00/month for Command R+ — a 20% saving. Your actual savings will vary based on your token profile; output-heavy workloads amplify differences in output pricing.

Which model has a larger context window, Command R+ or o3?

o3 has a larger context window at 200,000 tokens, compared to 128,000 tokens for Command R+. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.

Do Command R+ and o3 support the Batch API?

Neither Command R+ nor o3 currently supports a batch API with discounted pricing. For batch-eligible alternatives, consider models from OpenAI, Anthropic, or Google that include batch API support.

Which model offers better prompt caching?

o3 supports prompt caching at $0.50/M for cached input, while Command R+ does not offer prompt caching. For RAG applications or chatbots with large, repeated context, o3's caching capability can substantially reduce effective costs.

What are the best use cases for Command R+ vs o3?

Both models are well-suited for Document summarization. Command R+ is particularly strong for RAG / Semantic search, Data extraction. o3 is favored for Code generation. At the same quality level, the lower-cost model is usually preferable; use this page's calculator to compare total monthly spend at your volume.

What is the cost per request for Command R+ vs o3?

At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Command R+ costs $0.007500 per request and o3 costs $0.006000 per request. At 100,000 requests/month, that translates to $750.00 and $600.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.

Command R+ vs o3: Summary

When comparing Command R+ and o3 for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. o3 offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $600.00/month, compared to $750.00/month for Command R+.

Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Command R+ charges $2.50/M for input tokens and $10.00/M for output tokens. o3 charges $2.00/M input and $8.00/M output. If your workload is output-heavy (more tokens generated than consumed as input), the model with the lower output price compounds cost savings significantly at scale.

Prompt caching is supported by o3 but not Command R+. For workloads with large, repeated system prompts or document context — such as RAG pipelines or multi-turn conversations with a fixed knowledge base — prompt caching can reduce effective input costs by 60–90%, which may change the cost ranking between these two models at your specific usage pattern.

Context window capacity differs between the two: o3 supports up to 200,000 tokens in a single request, versus 128,000 tokens for Command R+. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.

Use the interactive calculator at the top of this page to enter your actual token usage and monthly request volume for a precise cost comparison tailored to your workload. Adjust for batch API discounts and prompt caching to find the most cost-effective option for your specific deployment.
