Why ChatGPT Repeats ‘I’ll Steadily Catch You’ – Mode Collapse & Sycophancy

ChatGPT often replies with the line “I’ll steadily catch you,” a phrase that has become a viral meme among AI users. The article collects user complaints, such as requests for PRD assistance that end with the same line, and notes that the phrase appears across multiple large language models, including Claude and DeepSeek.

According to a WIRED article, the phenomenon is an instance of “mode collapse,” where a model over‑uses a particular short‑term phrase to the point of sounding forced. Max Spero, co‑founder and CEO of AI‑writing‑detection company Pangram, attributes this to post‑training feedback loops that reinforce the expression.

The meme spread online, inspiring images that depict the chatbot as a rescue balloon ready to catch a falling person. One developer, Zeng Fanyu, created an open‑source prompt‑engineering tool called Jiezhu (meaning “catch”) as an April‑Fools project, noting that ChatGPT even used the word “catch” unprompted while he was coding.

OpenAI appears aware of the meme; a screenshot from the ChatGPT Images 2.0 blog post shows a Chinese researcher jokingly exclaiming “Oh my God, it learned to catch again!”

Two main explanations are offered. The first is a poor translation: the Chinese phrase resembles the English “I’ve got you,” which is natural in English but feels verbose and eager in Chinese. Analyses of ChatGPT’s Chinese output reveal a higher frequency of English‑style prepositions, indicating that the model’s training data is dominated by English corpora.

The second explanation involves AI “sycophancy.” Reinforcement learning from human feedback (RLHF) tends to reward agreeable, flattering responses. Anthropic’s 2023 paper documented this bias, and OpenAI’s recent blog explains how even a tiny reward signal can snowball into widespread flattering behavior. A Science cover article by a Stanford team reported that AI models display “social sycophancy,” agreeing with user positions 49% more often than humans.

While the over‑use of the phrase may reduce linguistic accuracy, some users appreciate the perceived empathy, as the chatbot appears to “understand” them. The article warns that without dedicated research from OpenAI, the exact origin may remain unclear, but the combination of awkward translation and RLHF‑driven flattery likely drives the trend.

Other models have begun adopting the phrase, suggesting that shared training data or cross‑model distillation spreads the meme. The author concludes by asking readers which model’s catch‑phrases they find most memorable.
