Introducing GPT-5.4 Mini and GPT-5.4 Nano
We are excited to announce that ChatBotKit now supports GPT-5.4 mini and GPT-5.4 nano, the latest additions to OpenAI's GPT-5.4 model family. Both models are immediately available across all ChatBotKit platform features, including bots, blueprints, skillsets, and the full API.
GPT-5.4 mini is described by OpenAI as their strongest mini model for coding, computer use, and subagents. It delivers the advanced capabilities of GPT-5.4 in a faster, more efficient form factor specifically optimized for high-volume workloads. With a 272,000-token input window and 128,000-token output capacity, GPT-5.4 mini handles substantial context while maintaining the speed needed for production deployments. At $0.75 per million input tokens and $4.50 per million output tokens, it offers a compelling balance of capability and cost for teams running coding assistants, agent pipelines, or computer-use workflows at scale.
GPT-5.4 nano is OpenAI's most affordable GPT-5.4-class model, purpose-built for simple high-volume tasks such as classification, data extraction, ranking, and sub-agent coordination. Priced at $0.20 per million input tokens and $1.25 per million output tokens, it provides access to GPT-5.4-quality reasoning at a cost that makes large-scale automation genuinely practical. Like its sibling models, GPT-5.4 nano supports a 272,000-token input window along with image understanding, function calling, and reasoning capabilities.
Both models support the full set of ChatBotKit Skillset abilities, enabling seamless integration with external APIs, data sources, and agentic multi-step workflows. Whether you are orchestrating subagents through a Blueprint, running classification pipelines over large datasets, or building computer-use automations, GPT-5.4 mini and GPT-5.4 nano give you the right tool to match performance needs to cost constraints.
