o1 vs o1-mini: Which Should You Choose?
Choosing between o1 and o1-mini depends on your priorities: cost efficiency, context length, or raw capability. o1-mini is the more affordable option at $1.10/1M input tokens — 93% cheaper than o1. Meanwhile, o1 offers a significantly larger context window at 200,000 tokens vs 128,000 for o1-mini.
Both models are in the reasoning category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: o1-mini would save you roughly $12,510.00/month compared to o1. For startups and indie developers, that difference can be significant.
Output costs matter too. o1 charges $60.00/1M output tokens vs $4.40 for o1-mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. o1-mini has the edge here at $4.40/1M output tokens.
