Introducing GPT-5.4 and GPT-5.4 Pro
We are excited to announce that ChatBotKit now supports GPT-5.4 and GPT-5.4 Pro, the newest additions to OpenAI's GPT-5 model family. Both models are immediately available across all ChatBotKit platform features, including bots, blueprints, skillsets, and the full API.
GPT-5.4 is OpenAI's latest frontier model for complex professional work, delivering the highest capability in the GPT-5 series. Designed to handle the most demanding reasoning, code generation, and knowledge work tasks, GPT-5.4 combines a massive 1,050,000-token context window with advanced multi-step reasoning and strong function calling support. The model's expansive context capacity means entire codebases, lengthy research documents, and extended multi-turn conversations remain fully accessible in a single inference pass - eliminating the need to chunk or summarize large inputs.
GPT-5.4 Pro takes the same foundation and amplifies it with more compute applied at inference time, enabling deeper deliberation on the hardest professional tasks. When consistent precision and sophistication matter most - whether auditing complex code, producing high-quality analysis across a vast corpus, or orchestrating intricate multi-tool agent workflows - GPT-5.4 Pro delivers more reliable and thoroughly reasoned results. It is particularly well suited for production deployments where accuracy consistently outweighs speed.
Both models support image understanding, function calling, and reasoning capabilities, making them powerful choices within ChatBotKit's Blueprint-based agentic architectures. Their integration with ChatBotKit Skillsets allows GPT-5.4 and GPT-5.4 Pro to seamlessly coordinate external APIs, manage long-running task sequences, and synthesize information from diverse sources - all within a single, coherent workflow.
GPT-5.4 and GPT-5.4 Pro are now available in the ChatBotKit model picker. Select either model from your dashboard or reference them directly through the API to start taking advantage of OpenAI's latest capabilities in your applications and agent workflows.
