OpenAI GPT-5.4 Series: New Nano Model at $0.20/MTok Input
OpenAI expands its model lineup with GPT-5.4 Nano, the most affordable model yet at $0.20 input / $1.25 output per million tokens.
OpenAI Launches GPT-5.4 Series with Budget-Friendly Nano Model
OpenAI has expanded its model lineup with the GPT-5.4 series, introducing the ultra-affordable GPT-5.4 Nano at just $0.20 per million input tokens and $1.25 per million output tokens.
The GPT-5.4 Lineup
| Model | Input/MTok | Output/MTok | Best For |
|---|---|---|---|
| GPT-5.4 Nano | $0.20 | $1.25 | Simple tasks, classification |
| GPT-5.4 | $2.50 | $15.00 | General purpose |
| GPT-5.4 Pro | $2.50 | $15.00 | Complex reasoning |
Why GPT-5.4 Nano Matters
At $0.20/MTok input, GPT-5.4 Nano is now the cheapest model from a major provider (excluding open-source hosted options).
Use Cases for Nano
- Content classification and tagging
- Simple Q&A and FAQ responses
- Data extraction from structured documents
- Sentiment analysis at scale
- Translation for common language pairs
Enterprise Implications
For enterprises running millions of API calls daily, the cost difference is substantial. A workload processing 100M tokens/day would cost:
- GPT-5.4: $250/day ($7,500/month)
- GPT-5.4 Nano: $20/day ($600/month)
That's a 92% cost reduction for tasks that don't require the full model's capabilities.
Bottom Line
OpenAI's tiered approach gives developers more flexibility to match model capability with task complexity, potentially reducing costs by 90%+ for simple workloads.
