Frequently Asked Questions
Is Claude Opus 4 cheaper than DeepSeek V4 Pro?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), DeepSeek V4 Pro costs $87.00/month versus $5,250.00/month for Claude Opus 4 — a 98% 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 Opus 4 or DeepSeek V4 Pro?
DeepSeek V4 Pro has a larger context window at 1,048,576 tokens, compared to 200,000 tokens for Claude Opus 4. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Claude Opus 4 and DeepSeek V4 Pro support the Batch API?
Claude Opus 4 supports the Batch API (50% discount for async processing), while DeepSeek V4 Pro does not. If your workload tolerates up to 24-hour latency, routing to Claude Opus 4 with batch pricing could significantly cut costs versus DeepSeek V4 Pro's standard rate.
Which model offers better prompt caching?
Claude Opus 4 supports prompt caching at $1.50/M for cached input, while DeepSeek V4 Pro does not offer prompt caching. For RAG applications or chatbots with large, repeated context, Claude Opus 4's caching capability can substantially reduce effective costs.
What are the best use cases for Claude Opus 4 vs DeepSeek V4 Pro?
Claude Opus 4 is best suited for Code generation, Document summarization, RAG / Semantic search, while DeepSeek V4 Pro is optimized for General chatbot. Choose based on which use case matches your primary workload — and validate with the cost calculator above to confirm the total monthly spend fits your budget.
What is the cost per request for Claude Opus 4 vs DeepSeek V4 Pro?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Claude Opus 4 costs $0.052500 per request and DeepSeek V4 Pro costs $0.000870 per request. At 100,000 requests/month, that translates to $5,250.00 and $87.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Claude Opus 4 vs DeepSeek V4 Pro: Summary
When comparing Claude Opus 4 and DeepSeek V4 Pro for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. DeepSeek V4 Pro offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $87.00/month, compared to $5,250.00/month for Claude Opus 4.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Claude Opus 4 charges $15.00/M for input tokens and $75.00/M for output tokens. DeepSeek V4 Pro charges $0.44/M input and $0.87/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 Claude Opus 4 but not DeepSeek V4 Pro. 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: DeepSeek V4 Pro supports up to 1,048,576 tokens in a single request, versus 200,000 tokens for Claude Opus 4. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
