Introducing OpenAI GPT 5.5

ChatBotKit now supports OpenAI GPT-5.5, OpenAI's newest frontier model for the most complex professional work. It is available across the platform for bots, blueprints, skillsets, and direct API use, giving teams immediate access to a model designed for advanced coding, deeper reasoning, and high-stakes production workflows.

GPT-5.5 expands what teams can confidently build with ChatBotKit. OpenAI positions it as a new class of intelligence for coding and professional work, and that makes it a strong fit for agentic systems that need to navigate large codebases, coordinate multi-step tool use, produce structured outputs, and sustain quality across long-running tasks. For developers building serious automation, the practical gain is not just better answers, but stronger execution on workflows where precision and persistence matter.

The model brings a 1,050,000-token context window and up to 128,000 output tokens, making it well suited to repositories, long conversations, large specifications, and multi-document reasoning sessions that would force smaller models to compress or drop important context. GPT-5.5 also supports function calling and image input, which makes it a natural choice for ChatBotKit Skillsets, Blueprint-based automations, and applications that combine language, tools, and visual context in a single flow.

This release gives ChatBotKit users another top-tier OpenAI option at the frontier end of the model catalog. If you need a model for demanding coding tasks, rigorous professional analysis, or agent workflows that must stay coherent over very large contexts, GPT-5.5 is now ready to use from the model picker and through the API.
