Frequently Asked Questions

How much cheaper is GPT-4.1 mini than Claude 3.5 Sonnet?

GPT-4.1 mini is dramatically cheaper — 8x less per request than Claude 3.5 Sonnet. GPT-4.1 mini is cheaper on both input ($0.4/M vs $3.0/M) and output ($1.6/M vs $15.0/M). At a fraction of the cost, GPT-4.1 mini saves significantly in production workloads. This comparison assumes a typical request of 5,000 input and 1,000 output tokens (5:1 ratio). Actual ratios vary by workload — chat and completion tasks typically run 2:1, code review around 3:1, document analysis and summarization 10:1 to 50:1, and embedding workloads are pure input with no output tokens.

How much does GPT-4.1 mini outperform Claude 3.5 Sonnet on benchmarks?

GPT-4.1 mini scores higher overall (22.9 vs 15.9). GPT-4.1 mini leads on GPQA (0.66 vs 0.6) and AIME (0.43 vs 0.16), with both within 5% on MMLU-Pro. GPT-4.1 mini scores proportionally higher on AIME (mathematical reasoning) relative to its MMLU-Pro, while Claude 3.5 Sonnet's scores are more weighted toward general knowledge. If mathematical reasoning matters, GPT-4.1 mini's AIME score of 0.43 gives it an edge.

How much more context can GPT-4.1 mini handle than Claude 3.5 Sonnet?

GPT-4.1 mini has a much larger context window — 1,047,576 tokens vs Claude 3.5 Sonnet at 200,000 tokens. That's roughly 1,396 vs 266 pages of text. GPT-4.1 mini's window can handle entire codebases or book-length documents; Claude 3.5 Sonnet works better for shorter inputs.

Is GPT-4.1 mini worth choosing over Claude 3.5 Sonnet on value alone?

GPT-4.1 mini offers dramatically better value — $0.0002 per intelligence point vs Claude 3.5 Sonnet at $0.0019. GPT-4.1 mini is both cheaper and higher-scoring, making it the clear value pick. You don't sacrifice quality to save money with GPT-4.1 mini.

How does prompt caching affect Claude 3.5 Sonnet and GPT-4.1 mini pricing?

With prompt caching, GPT-4.1 mini is dramatically cheaper — 8x less per request than Claude 3.5 Sonnet. Caching saves 45% on Claude 3.5 Sonnet and 42% on GPT-4.1 mini compared to standard input prices. Both models benefit from caching at similar rates, so the uncached price comparison holds.
