Developers complain GPT-5.5 lags as OpenAI retires older models

The content discusses various updates and issues related to OpenAI's GPT models. It highlights dissatisfaction from developers regarding the GPT-5.5 model, with concerns over cognitive capability and increased processing latency. Several legacy models, notably GPT-5.2 and GPT-5.3-Codex, are being deprecated from June 2, while premium subscribers will continue to access GPT-5.4 and GPT-5.5. Free-tier users will default to GPT-5.5, with no option to select alternative models. API consumers remain unaffected. Additionally, specialized models, like GPT-5.3-Codex-Spark, will maintain their distribution.
