Frequently Asked Questions
Is Gemma 3 27B (Bedrock) cheaper than GPT-4.1 nano?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), GPT-4.1 nano costs $30.00/month versus $42.00/month for Gemma 3 27B (Bedrock) — a 29% 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, Gemma 3 27B (Bedrock) or GPT-4.1 nano?
GPT-4.1 nano has a larger context window at 1,047,576 tokens, compared to 128,000 tokens for Gemma 3 27B (Bedrock). A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Gemma 3 27B (Bedrock) and GPT-4.1 nano support the Batch API?
GPT-4.1 nano supports the Batch API (50% discount for async processing), while Gemma 3 27B (Bedrock) does not. If your workload tolerates up to 24-hour latency, routing to GPT-4.1 nano with batch pricing could significantly cut costs versus Gemma 3 27B (Bedrock)'s standard rate.
Which model offers better prompt caching?
GPT-4.1 nano supports prompt caching at $0.03/M for cached input, while Gemma 3 27B (Bedrock) does not offer prompt caching. For RAG applications or chatbots with large, repeated context, GPT-4.1 nano's caching capability can substantially reduce effective costs.
What are the best use cases for Gemma 3 27B (Bedrock) vs GPT-4.1 nano?
Gemma 3 27B (Bedrock) is best suited for Translation, Summarization, Content Creation, while GPT-4.1 nano is optimized for Text classification, Data extraction. 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 Gemma 3 27B (Bedrock) vs GPT-4.1 nano?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Gemma 3 27B (Bedrock) costs $0.000420 per request and GPT-4.1 nano costs $0.000300 per request. At 100,000 requests/month, that translates to $42.00 and $30.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Gemma 3 27B (Bedrock) vs GPT-4.1 nano: Summary
When comparing Gemma 3 27B (Bedrock) and GPT-4.1 nano for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. GPT-4.1 nano offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $30.00/month, compared to $42.00/month for Gemma 3 27B (Bedrock).
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Gemma 3 27B (Bedrock) charges $0.23/M for input tokens and $0.38/M for output tokens. GPT-4.1 nano charges $0.10/M input and $0.40/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 GPT-4.1 nano but not Gemma 3 27B (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: GPT-4.1 nano supports up to 1,047,576 tokens in a single request, versus 128,000 tokens for Gemma 3 27B (Bedrock). A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
