Changed
- Updates to GPT-4o
- We've reverted the most recent update to GPT-4o due to issues with overly agreeable responses (sycophancy). We’re actively working on further improvements. For more details, check out our blog post explaining what happened and our initial findings, and this blog post where we expand on what we missed with sycophancy and the changes we're going to make going forward.
