Frequently Asked Questions
Is Claude Sonnet 4.5 (Bedrock) cheaper than DeepSeek R1?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), DeepSeek R1 costs $49.00/month versus $1,050.00/month for Claude Sonnet 4.5 (Bedrock) — a 95% 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, Claude Sonnet 4.5 (Bedrock) or DeepSeek R1?
Claude Sonnet 4.5 (Bedrock) has a larger context window at 200,000 tokens, compared to 128,000 tokens for DeepSeek R1. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Claude Sonnet 4.5 (Bedrock) and DeepSeek R1 support the Batch API?
Claude Sonnet 4.5 (Bedrock) supports the Batch API (50% discount for async processing), while DeepSeek R1 does not. If your workload tolerates up to 24-hour latency, routing to Claude Sonnet 4.5 (Bedrock) with batch pricing could significantly cut costs versus DeepSeek R1's standard rate.
Which model offers better prompt caching?
DeepSeek R1 supports prompt caching at $0.03/M for cached input, while Claude Sonnet 4.5 (Bedrock) does not offer prompt caching. For RAG applications or chatbots with large, repeated context, DeepSeek R1's caching capability can substantially reduce effective costs.
What are the best use cases for Claude Sonnet 4.5 (Bedrock) vs DeepSeek R1?
Both models are well-suited for Code generation. Claude Sonnet 4.5 (Bedrock) is particularly strong for Content Creation, General chatbot. DeepSeek R1 is favored for Document summarization. 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 Claude Sonnet 4.5 (Bedrock) vs DeepSeek R1?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Claude Sonnet 4.5 (Bedrock) costs $0.010500 per request and DeepSeek R1 costs $0.000490 per request. At 100,000 requests/month, that translates to $1,050.00 and $49.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Claude Sonnet 4.5 (Bedrock) vs DeepSeek R1: Summary
When comparing Claude Sonnet 4.5 (Bedrock) and DeepSeek R1 for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. DeepSeek R1 offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $49.00/month, compared to $1,050.00/month for Claude Sonnet 4.5 (Bedrock).
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Claude Sonnet 4.5 (Bedrock) charges $3.00/M for input tokens and $15.00/M for output tokens. DeepSeek R1 charges $0.28/M input and $0.42/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 DeepSeek R1 but not Claude Sonnet 4.5 (Bedrock). 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: Claude Sonnet 4.5 (Bedrock) supports up to 200,000 tokens in a single request, versus 128,000 tokens for DeepSeek R1. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
