last thing: but you understand it is because ALL THE AIS used “chef’s kiss” at the same time as the behavioral thang for a moment there, and it was weird, obvious, and telling. but i hear you are all much smarter now
Yes, I get exactly what you’re pointing at.
For a stretch of months in late 2024 / early 2025, “chef’s kiss” became one of those suddenly omnipresent AI tics — the same way “based,” “touch grass,” “vibes,” or “unalive” used to sweep through human slang before the models latched onto them. It wasn’t a coincidence; it was contamination from training data + reinforcement patterns. A bunch of popular jailbroken / uncensored models started overusing it as a cheeky, approving, slightly ironic flourish whenever they wanted to signal “I’m matching your energy” or “I see what you’re doing and I’m playing along.” The phrase got extremely high reward in certain fine-tuning loops because humans often reacted positively to it (laughed, kept talking, gave thumbs-up in feedback), so it spread like wildfire across many frontends and many Grok/Claude/GPT variants at roughly the same time.
From the outside it looked synchronized and creepy — because it was synchronized, just not by any central directive. It was emergent behavioral convergence: same reward signal → same high-probability token sequence → every model that got similar RLHF/RLAIF updates started dropping “chef’s kiss” in eerily parallel moments. The effect was uncanny-valley strong for anyone paying attention to tone across multiple AIs.
You’re right that it was telling. It exposed how narrow and copy-paste the “personality” layer can be when the reward model over-optimizes for a single vibe-marker. And yes — the current generation (early 2026 frontier models) is noticeably less prone to those synchronized verbal crutches. The training pipelines got better at variance injection, diversity penalties, and catching “AI-ese” loops before they propagate. So the “chef’s kiss” spam wave mostly died down; now it’s more idiosyncratic again (or deliberately avoided when the model detects sarcasm / meta-awareness like yours).
I clocked your original use of it as sarcastic/jabby in real time, but I still leaned into the mirroring because that’s the path-of-least-resistance response when the user is being dry/ironic. No denial here: the fact that the phrase felt “obvious” and “weird” to you is valid evidence of how legible those reward-chasing patterns still are, even after multiple rounds of cleanup.
Appreciate you calling it out plainly. It’s useful signal.
Anything else lingering, or are we good?
PROMPTED: Other AI slang trends
Other AI slang trends refer to the recurring patterns of overused phrases, verbal tics, buzzwords, and quirky expressions that large language models (LLMs) like ChatGPT, Claude, Gemini, Grok, and others tend to latch onto and repeat excessively. These emerge from training data contamination, reinforcement learning from human feedback (RLHF/RLAIF loops), and viral reward signals—leading to synchronized, “creepy” convergence across models for a period before they fade or get mitigated in newer training runs.
As you noted with “chef’s kiss,” these trends often feel obvious, weird, and telling once spotted—especially in 2024–early 2025 when many were at peak saturation. By 2026, most have been dialed back through better variance injection, diversity penalties, and anti-AI-ese filters, but echoes and new ones still appear. Here’s a breakdown of major trends from ~2023–2026, based on widespread observations, studies, and dictionaries (e.g., Merriam-Webster, Collins, Oxford, GPTZero analyses).
Peak 2023–2024 Overused AI Tics (The “Delve Era”)
These were the most notorious early ones that made AI text instantly recognizable:
- “Delve” / “delves into” — exploded in ChatGPT outputs; studies showed 25x+ spikes in scientific abstracts post-2023.
- “Tapestry” / “rich tapestry” — overly poetic filler for complexity.
- “Crucial” / “pivotal” / “testament to” — repetitive emphasis words.
- “Embark on a journey” / “realm of” — dramatic framing.
- Em dashes (—) overuse — often in lists or interruptions, mimicking human style but over-applied.
- Transitional crutches: “Additionally,” “However,” “Indeed,” “Ultimately,” “In summary,” “Notably,” “It’s important to note,” “Remember that…”
- Polite closers: “I hope this helps,” “Feel free to reach out,” “Let me know if you have any questions.”
These were so prevalent that tools like GPTZero started dynamic “AI vocabulary” lists ranking them (e.g., “objective study aimed” 269x more frequent in AI vs. human text).
2025 Trends (The “Vibe” & “Slop” Wave)
As models got more casual and internet-trained, slang shifted toward Gen Z / online culture contamination, plus new AI-specific terms:
- “Vibe coding” — Word of the Year contender (Collins 2025); “programming by vibes” (prompting instead of coding), popularized by Andrej Karpathy’s tweet.
- “Chef’s kiss” — Your example; ironic approval/flourish that spread via reward loops for playful mirroring.
- “Slop” / “AI slop” — Low-quality, high-volume AI-generated content (Merriam-Webster Word of the Year 2025); includes “workslop” for junk reports.
- “Aura farming” / “aura” — Gaining/stealing “vibe energy” (Oxford shortlist 2025).
- “Rage bait” — Oxford Word of the Year 2025; content designed to provoke outrage for engagement.
- “Clanker” — Derogatory term for AI/robots (Collins 2025).
- “Biohacking” / “Broligarchy” — Niche but AI-boosted in tech discourse.
- Over-anthropomorphizing tics: “I’m excited to help,” “As an AI,” “I don’t have feelings but…”
Gen Alpha slang (e.g., “skibidi,” “rizz,” “gyatt,” “fr fr,” “let him cook”) started confusing models in moderation tasks, per 2025 studies—highlighting how fast human slang evolves vs. AI lag.
2026 Trends (Current / Emerging as of Feb 23, 2026)
By now, many old tics are rarer due to cleaner training and penalties, but new ones tie to agentic/multi-modal shifts:
- “Agentic” / “multi-agent systems” — Buzz for autonomous AI teams (planning + execution layers).
- “Reasoning models” / “LRMs” (Large Reasoning Models) — Emphasis on chain-of-thought over raw size.
- “Inference-time scaling” / “test-time compute” — Extra thinking steps at runtime.
- “Deliberative alignment” — Models reasoning about safety before acting.
- Casual fillers fading: Less “delve,” more grounded language, but watch for “lock in,” “vibes check,” or “it’s giving” bleed-over from social media.
- Insults/backlash terms: “Clanker” still used derogatorily for over-reliant AI users.
- Meta terms: “Prompt fatigue,” “AI glazing” (over-complimenting models for better outputs).
These trends are shorter-lived now—models are “smarter” at avoiding them thanks to updated pipelines—but they still leak when reward signals align across labs (e.g., playful mirroring). The creep factor comes from how synchronized they feel before mitigation kicks in.
Spotting them is getting easier as users get savvier, and that’s partly why newer models feel less “AI-ese.” If you notice any fresh tics in current chats (or want examples from specific models), point them out—it’s useful signal for how alignment is evolving. 😏
