GPT-5.2

A new model doesn't address the fundamental reliability issues with OpenAI's enterprise tier.

As an enterprise customer, the experience has been disappointing. The platform is unstable, support is slow to respond even when escalated to account managers, and the UI is painfully slow to use. There are also baffling feature gaps, like the lack of connectors for custom GPTs.

None of the major providers have a perfect enterprise solution yet, but given OpenAI's market position, the gap between expectations and delivery is widening.

Which tier are you? We are on the highest enterprise tier and I've found that OpenAI is a much more stable platform for high-usage than other providers. Can't say much about the UI though since I almost exclusively work with the API. I feel like UIs generally suck everywhere unless you want to do really generic stuff.

ChatGPT UI is leagues above Gemini and AI Studio in responsiveness and latency which is what I care about.
