ChatGPT: OpenAI's Chatbot Evolution

OpenAI’s Foray into Creative Writing with AI

In March 2025, Sam Altman, CEO of OpenAI, disclosed in a podcast that the company had developed an AI model exhibiting ‘remarkable proficiency’ in creative writing. A substantial writing sample from the model was shared, generated from the prompt: ‘Please write a metafictional literary short story about AI and grief.’ This represents a significant shift for OpenAI, traditionally focused on AI applications in structured fields like mathematics and programming. The sample demonstrated the model’s unexpected creative writing capabilities.

Empowering Businesses with AI Agent Building Tools

Also in March 2025, OpenAI introduced new tools to help businesses build custom AI agents. These tools, leveraging OpenAI’s proprietary AI models and frameworks, are integrated into the new Responses API. This API allows enterprises to create AI agents capable of web searches, company data analysis, and website navigation, similar to existing AI assistants. The Responses API is set to replace the Custom Instructions API, which will be phased out in the first half of 2026.

OpenAI’s Pricing Strategy for Specialized AI Agents

Reports emerged in March 2025 suggesting OpenAI’s plan to introduce specialized AI agents for various applications, including sales lead sorting and ranking, and software engineering.

The ‘high-income knowledge worker’ agent is reportedly priced at $2,000 per month, the software developer agent at $10,000 per month, and the most premium agents, designed for ‘PhD-level research,’ at $20,000 per month. These figures highlight OpenAI’s substantial financial needs, having incurred a loss of approximately $5 billion in the previous year. The launch timeline and customer eligibility for these agentic tools remain unclear.
