OpenAI removes access to sycophancy-prone GPT-4o model
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.
