Frequently Asked Questions
Is DeepSeek R1 cheaper than Nano Banana Pro (Gemini 3 Pro Image)?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), DeepSeek R1 costs $49.00/month versus $800.00/month for Nano Banana Pro (Gemini 3 Pro Image) — a 94% 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, DeepSeek R1 or Nano Banana Pro (Gemini 3 Pro Image)?
DeepSeek R1 has a larger context window at 128,000 tokens, compared to 65,536 tokens for Nano Banana Pro (Gemini 3 Pro Image). A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do DeepSeek R1 and Nano Banana Pro (Gemini 3 Pro Image) support the Batch API?
Neither DeepSeek R1 nor Nano Banana Pro (Gemini 3 Pro Image) 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?
DeepSeek R1 supports prompt caching at $0.03/M for cached input, while Nano Banana Pro (Gemini 3 Pro Image) 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 DeepSeek R1 vs Nano Banana Pro (Gemini 3 Pro Image)?
DeepSeek R1 is best suited for Code generation, Document summarization, while Nano Banana Pro (Gemini 3 Pro Image) 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 DeepSeek R1 vs Nano Banana Pro (Gemini 3 Pro Image)?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — DeepSeek R1 costs $0.000490 per request and Nano Banana Pro (Gemini 3 Pro Image) costs $0.008000 per request. At 100,000 requests/month, that translates to $49.00 and $800.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
DeepSeek R1 vs Nano Banana Pro (Gemini 3 Pro Image): Summary
When comparing DeepSeek R1 and Nano Banana Pro (Gemini 3 Pro Image) 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 $800.00/month for Nano Banana Pro (Gemini 3 Pro Image).
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. DeepSeek R1 charges $0.28/M for input tokens and $0.42/M for output tokens. Nano Banana Pro (Gemini 3 Pro Image) charges $2.00/M input and $12.00/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 DeepSeek R1 but not Nano Banana Pro (Gemini 3 Pro Image). 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 R1 supports up to 128,000 tokens in a single request, versus 65,536 tokens for Nano Banana Pro (Gemini 3 Pro Image). A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
