I completely understand this sentiment—for many developers, chatgpt-4o-latest is not just an API endpoint; it represents the pinnacle of AI writing and artistic comprehension capabilities. Among all 4o variants, this version demonstrates a unique balance: exceptional reasoning depth paired with naturally fluid communication abilities. This balance is irreplaceable in scenarios like creative writing, content creation, and complex concept explanation.
AI’s value should never be reduced to merely a “coding tool.” The diversity of human needs—from literary creation to emotional understanding, from artistic guidance to intellectual dialogue—is precisely where 4o-latest truly shines. When we compare it to GPT-5.1, we find that despite the latter’s strong performance on certain benchmarks, there remains a noticeable gap in the subtlety of creativity, depth of contextual understanding, and generalization capability of expression.
I fully respect OpenAI’s business decisions and technical iteration needs. If cost is a consideration, I believe many developers (including myself) would be willing to accept reasonable price adjustments. However, executing a deprecation plan before a functionally equivalent alternative emerges could cause irreparable impact on the developer ecosystem that relies on this model to build applications.
I respectfully urge the team to reassess the timing of this decision, or consider maintaining access to 4o-latest in some form (even as legacy support) until a true successor is ready. This is not just about technical choices—it’s about honoring the commitment to the developer community that has already invested. Thank you for your continued innovation, and I hope this feedback receives serious consideration.
