OpenAI unveils GPT-5.4 mini with 2x speed for ChatGPT and API
OpenAI launched GPT-5.4 mini, a new version of its generative AI model offering twice the speed of GPT-5 mini for users of ChatGPT, Codex, and the API.
The update focuses on enhancing coding tasks, computer applications, multimodal understanding, and enabling subagents. The accelerated performance is designed to help developers and businesses streamline workflows and improve productivity. OpenAI continues to compete for leadership in AI-powered coding and developer tools as the market for advanced artificial intelligence systems rapidly expands.
The debut of GPT-5.4 mini underscores OpenAI’s strategy of accelerating product iterations to maintain a competitive advantage, building on previous advancements such as the introduction of GPT-5.3 Instant, which enhanced accuracy and conversational capability for ChatGPT users. This ongoing momentum is further supported by substantial backing, following new investments from SoftBank, NVIDIA, and Amazon aimed at scaling AI infrastructure and broadening accessibility.
