GPT-4o mini vs GPT-5.4 mini: Which Should You Choose?
Choosing between GPT-4o mini and GPT-5.4 mini depends on your priorities: cost efficiency, context length, or raw capability. GPT-4o mini is the more affordable option at $0.15/1M input tokens — 80% cheaper than GPT-5.4 mini. Meanwhile, GPT-5.4 mini offers a significantly larger context window at 1,050,000 tokens vs 128,000 for GPT-4o mini.
Both models are in the efficient category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: GPT-4o mini would save you roughly $765.00/month compared to GPT-5.4 mini. For startups and indie developers, that difference can be significant.
Output costs matter too. GPT-4o mini charges $0.60/1M output tokens vs $4.50 for GPT-5.4 mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-4o mini has the edge here at $0.60/1M output tokens.
Multimodal capabilities: Both models support vision (image understanding), so you can send images alongside text prompts with either option.
Best Use Cases
Choose GPT-4o mini when:
- • Budget is a primary concern
- • You're already using OpenAI's API ecosystem
- • You're running high-volume, latency-sensitive workloads
Choose GPT-5.4 mini when:
- • You need a larger context window (1,050,000 tokens)
- • You need more capabilities (code)
- • You need longer outputs (up to 65,536 tokens)
- • You're already using OpenAI's API ecosystem
- • You're running high-volume, latency-sensitive workloads
