GPT-4.1 vs o4-mini: Which Should You Choose?
Choosing between GPT-4.1 and o4-mini depends on your priorities: cost efficiency, context length, or raw capability. o4-mini is the more affordable option at $1.10/1M input tokens — 45% cheaper than GPT-4.1. Meanwhile, o4-mini offers a significantly larger context window at 2,000,000 tokens vs 200,000 for GPT-4.1.
These models target different tiers: GPT-4.1 is a flagship model while o4-mini is reasoning. This means they're optimized for different workloads. GPT-4.1 is built for complex tasks that require deeper reasoning, while o4-mini offers better value for routine operations.
Output costs matter too. GPT-4.1 charges $8.00/1M output tokens vs $4.40 for o4-mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. o4-mini has the edge here at $4.40/1M output tokens.
Multimodal capabilities: GPT-4.1 supports vision (image inputs) while o4-mini is text-only. If your application needs image understanding, this narrows your choice.
