GPT-5.4 nano
GPT-5.4 nano is OpenAI's cheapest current tier — about $0.20 / $1.25 per 1M tokens — built for simple, high-volume calls: classification, extraction, routing, short drafts. Like Haiku and Gemini Flash-Lite it is the 'cheap leg' you route bulk work to while a flagship handles the hard steps. It plugs into OpenAI's large tool and integration ecosystem. Closed and cloud-only; OpenAI now offers EU data-residency endpoints (about a 10% uplift) for models released from March 2026, which helps the GDPR story — confirm your specific model and region qualify.
