# OpenAI Releases GPT-5.1 with Enhanced Developer Tools

OpenAI announced the launch of GPT-5.1, now available through its API for developers worldwide.

The new model introduces several key improvements over its predecessor. Most notably, GPT-5.1 features faster adaptive reasoning capabilities, allowing the AI to process and respond to complex queries more efficiently. The update also includes extended prompt caching, which should reduce costs and latency for applications that use repeated prompts.

For software developers, OpenAI has significantly enhanced coding performance and added two new practical tools: `apply_patch` and `shell`. These tools suggest OpenAI is positioning GPT-5.1 as a more capable coding assistant that can directly interact with development workflows, potentially applying code changes and executing shell commands.

The release represents OpenAI's continued push to make its AI models more practical for real-world applications. By focusing on speed
