Model Comparison
OpenAI's GPT-4o mini costs less per intelligence point, even though Anthropic's Claude 4 Sonnet (Non-reasoning) scores higher.
Data last updated March 4, 2026
GPT-4o mini delivers more intelligence per dollar, while Claude 4 Sonnet (Non-reasoning) leads on raw benchmark scores. Claude 4 Sonnet (Non-reasoning) costs $0.03 per request vs $0.0014 for GPT-4o mini (at 5K input / 1K output tokens). The question is whether Claude 4 Sonnet (Non-reasoning)'s higher scores justify the 22x price premium.

GPT-4o mini is dramatically cheaper — 22x less per request than Claude 4 Sonnet (Non-reasoning). GPT-4o mini is cheaper on both input ($0.15/M vs $3.0/M) and output ($0.6/M vs $15.0/M). At a fraction of the cost, GPT-4o 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.
Claude 4 Sonnet (Non-reasoning) scores higher overall (33.0 vs 12.6). Claude 4 Sonnet (Non-reasoning) leads on MMLU-Pro (0.84 vs 0.65), GPQA (0.68 vs 0.43), AIME (0.41 vs 0.12). If mathematical reasoning matters, Claude 4 Sonnet (Non-reasoning)'s AIME score of 0.41 gives it an edge.
GPT-4o mini is 5% faster at 50.9 tokens per second compared to Claude 4 Sonnet (Non-reasoning) at 48.5 tokens per second. GPT-4o mini also starts generating sooner at 0.47s vs 1.03s time to first token. The speed difference matters for chatbots but is less relevant in batch processing.
Claude 4 Sonnet (Non-reasoning) has a 56% larger context window at 200,000 tokens vs GPT-4o mini at 128,000 tokens. That's roughly 266 vs 170 pages of text. The extra context capacity in Claude 4 Sonnet (Non-reasoning) matters for document analysis and long conversations.
GPT-4o mini offers dramatically better value — $0.0001 per intelligence point vs Claude 4 Sonnet (Non-reasoning) at $0.0009. GPT-4o mini is cheaper, which offsets Claude 4 Sonnet (Non-reasoning)'s higher benchmark scores to deliver more value per dollar. If raw benchmark scores matter less than cost for your use case, GPT-4o mini is the efficient choice.
With prompt caching, GPT-4o mini is dramatically cheaper — 17x less per request than Claude 4 Sonnet (Non-reasoning). Caching saves 45% on Claude 4 Sonnet (Non-reasoning) and 28% on GPT-4o mini compared to standard input prices. Claude 4 Sonnet (Non-reasoning) benefits more from caching. If your workload has repetitive prompts, Claude 4 Sonnet (Non-reasoning)'s cache discount gives it a bigger cost advantage than list prices suggest.
