Verdict
GPT-5.2 costs $1.75 per 1M input tokens and $14.00 per 1M output tokens. GPT-4.1 costs $2.00 per 1M input tokens and $8.00 per 1M output tokens. GPT-5.2 is 13% cheaper on input tokens than GPT-4.1. For output tokens, GPT-4.1 is the more affordable option at $8.00/1M vs $14.00.
On context window, GPT-4.1 supports 1,000,000 tokens — meaning it can fit more conversation history, documents, or code in a single request. This matters for RAG pipelines, long document analysis, and agentic workflows where context builds up over many turns.
When to choose GPT-5.2
- ✓ You need the lowest input token cost ($ 1.75/1M)
- ✓ You are already integrated with OpenAI
When to choose GPT-4.1
- ✓ Your workload is output-heavy — GPT-4.1 generates text cheaper
- ✓ You need a larger context window (1,000,000 tokens)
- ✓ You are already integrated with OpenAI
Use the calculator above to simulate your specific workload and find the exact break-even point. For most applications, the cheapest model is the one that minimises your total monthly bill given your input-to-output token ratio.
