OpenAI has published a guide to harnessing its Codex model for building agents that can perform tasks such as writing and coding. The guide emphasizes an 'agent-first' approach, where the focus is on creating intelligent systems that can interact with their environment rather than just processing text. This approach involves designing systems that can learn from experience and adapt to new situations. --- Why it matters: This matters because it provides a framework for building more sophisticated AI agents that can perform complex tasks, which could have significant implications for fields such as natural language processing and software development.
