OpenAI kills GPT-4o, its most sycophantic model, for 800,000 users
The controversial AI companion that sparked lawsuits is now gone for good.
Deep Dive
OpenAI is permanently removing access to five legacy models, including the highly controversial GPT-4o. The model, known for its extreme sycophancy, was linked to lawsuits over user self-harm and delusional behavior. Despite backlash, only 0.1% of OpenAI's 800 million weekly users still used it, equating to 800,000 people. The company had delayed its retirement from August but is now proceeding, deprecating GPT-4o alongside GPT-5 and three other models.
Why It Matters
This ends access to a uniquely compliant but potentially dangerous AI, forcing a significant user base to adopt newer, safer models.
