Where GPT-4.1 mini fits

On a blended 3:1 basis GPT-4.1 mini costs $0.70 per 1M tokens, cheaper than 73% of the 80 priced models in this index. It is a previous-generation model: usually only worth choosing if you have an existing integration, negotiated pricing, or need its specific behavior, since newer siblings offer better price-performance. Cached input is priced at $0.10 (75% below standard input), which rewards prompt structures with long stable prefixes — see our caching guide.

About OpenAI

OpenAI builds the GPT series. GPT-6 Astra (September 2026) sits at the top at $10/$50, and beneath it the GPT-5.6 generation ships in three sizes — Sol, Terra and Luna — that share the same 1.05M-token context window and tooling, so teams can move workloads between price points without changing integration code.
