A lightweight variant of GPT-5.4 with a 400k token context window, optimized for speed and efficiency in high-volume batch workloads.
- Strengths
- Delivers fast inference and low resource consumption while maintaining reasoning and coding capabilities suitable for smaller, focused tasks.
- Best for
- High-volume batch processing where throughput and efficiency matter more than frontier-level reasoning or multimodal capabilities.
- Limitations
- Trades off raw reasoning power and capability breadth compared to GPT-5.4 Pro or GPT-5.5, and lacks vision capabilities available in GPT-5.4 Image 2.
