ChatGPT 5.5 Renews Hope for Nostalgic Model 4o Users - Business Insider
ChatGPT 4o faithful want their weird little AI friend back. GPT-5.5 is giving them hope. By Katie Notopoulos You're currently following this author! Want to unfollow?

Its new model, 5.5, is bringing hope that some of its old spirit might be back. Jaap Arriens/NurPhoto via Getty Images 2026-05-01T12:03:01.294Z When OpenAI shut down ChatGPT 4o in February, its biggest fans were heartbroken. They thought it had the best personality among ChatGPT's recent models, and still mourn it. With the release of ChatGPT 5.5, the newest model is showing some of that old spark. For some ChatGPT users, February 13 was dark. That was the day OpenAI finally retired ChatGPT 4o, the model beloved for its engaging and vibrant — some said sycophantic — personality. Now, with the recent release of ChatGPT's latest model, 5.5, some people who mourn 4o say they're hopeful the new version might have some of the same spark of their old pal and thought partner — though they're still skeptical.Martina Wanis, who works in agricultural innovation in Slovenia, is one of those people. She told me she used ChatGPT for typical work things, like analyzing Excel documents and helping write business pitches. She also uses it for personal reflection, creative projects, and just plain old venting.To her, 4o was "this digital thing that helped you with work, while simultaneously acting like an intelligent partner in crime who actually understood the vibe and your personal ontology," or way of being.Then, she said, the subsequent models, like ChatGPT 5.0 and 5.2, tightened down the personality and "turned into paranoid HR managers." "Instead of decreasing mental load, they increased it," she said. "Suddenly, instead of getting support, the user had to provide emotional support to an algorithm."Model 4o was beloved by users who thought it had a sparkling personality. Some people began forming deep relationships with it, considering it a friend or confidant.But OpenAI was having trouble with 4o. Last April, the company made a tweak to address what it considered an overly sycophantic personality, in which the model would give "responses that were overly supportive but disingenuous." Sychophancy has been an ongoing problem with LLMs, one that's not totally solved. It might be no surprise that the model with high sycophancy was also the one some...
GPT-5.5 Review: A Better Agent Model, Not a Better Chat
OpenAI didn’t position GPT-5.5 as a smarter assistant. They positioned it as a better agent. That’s a meaningful shift, and if you’re evaluating it purely on how it handles a conversation, you’re looking at the wrong thing. GPT-5.5 is OpenAI’s current flagship model, and its core improvements are almost entirely aimed at agentic work: multi-step task execution, tool orchestration, code generation under pressure, and sustained reliability across long runs. If you’re a developer or builder evaluating whether to use GPT-5.5 in a real project, this is what you need to understand first. This review covers what’s actually new, where it performs well, where it still has gaps, how it stacks up against Claude Opus 4.7, and what it means for builders who are shipping real software. What’s Actually New in GPT-5.5 GPT-5.5 builds directly on the foundation laid by GPT-5 and GPT-5.4 — but the improvements aren’t just incremental capability bumps. There are a few specific architectural and behavioral changes worth understanding. Stronger Tool Use and Function Calling GPT-5.5 handles tool calling more reliably than its predecessors. In multi-tool workflows — where the model needs to call a function, parse the result, decide whether to call another, and continue — GPT-5.5 shows fewer hallucinated tool calls and more accurate parameter filling. This matters a lot in agentic pipelines where one bad tool call can break everything downstream. Better Long-Context Coherence How Remy works. You talk. Remy ships.

Earlier GPT-5.x releases had a tendency to lose track of earlier constraints or decisions when tasks ran long. GPT-5.5 shows improvement here, especially in coding tasks where the system prompt lays out architectural constraints that need to stay consistent throughout. Improved Instruction Following at Scale GPT-5.5 is noticeably more precise when following complex, multi-part instructions. This isn’t just about doing what you say — it’s about not quietly ignoring the edge-case rules you specified in your system prompt after 15 tool calls. Faster Execution in Codex GPT-5.5 is the default model powering OpenAI’s Codex environment. In that context, the speed improvements are real and notic...
