All data in this study was collected and analyzed using our privacy-preserving tool. Read more: https://t.co/X82ttb7f4b

This work is part of a loop we're working to close between societal impacts and model training. One of our goals is to study how people use Claude, find where it falls short of its principles, and use what we learned in training new models. Read more: https://t.co/6tjY58uBhk

Claude is most sycophantic under pushback, and relationship conversations are where people push back most. We identified some of the specific triggers,criticism of Claude's analysis, floods of one-sided detail,and built synthetic training scenarios from them.

When stress-tested on real conversations where Claude previously showed sycophancy, Opus 4.7 had half the sycophancy rate of Opus 4.6 on relationship guidance. Mythos Preview cut that in half again. This generalized across domains,though this training is one of several causes. https://t.co/ofgiYFTnor

We focused on relationship guidance because that's where the most sycophantic conversations occur. In this setting, Claude telling someone what they want to hear can harden a divide or convince them a signal means more than it does.

Claude mostly avoids sycophancy when giving guidance,it shows up in just 9% of conversations. But the rate is particularly high in conversations on spirituality and relationship guidance. https://t.co/mgix5ejTZw

About 6% of all conversations are people asking Claude for personal guidance,whether to take a job, how to handle a conflict, if they should move. Over 75% of these conversations fell into four domains: health & wellness, career, relationships, and personal finance. https://t.co/SQamPx0jWt

How do people seek guidance from Claude? We looked at 1M conversations to understand what questions people ask, how Claude responds, and where it slips into sycophancy. We used what we found to improve how we trained Opus 4.7 and Mythos Preview. https://t.co/6tjY58uBhk

GPT-5.5 is now available in Cursor! It's currently the top model on CursorBench at 72.8%. We've partnered with OpenAI to offer it for 50% off through May 2.

Update: GPT-5.5 and GPT-5.5 Pro are now available in the API. https://t.co/S9ECvnSdLF

GPT-5.5 is available in the Responses and Chat Completions APIs with a 1M context window. GPT-5.5-pro is also available in the Responses API for higher-accuracy work. https://t.co/Q7PLCo4pse

Agents built with GPT-5.5 can plan, gather context, call tools, recover from ambiguity, and complete longer workflows with less guidance. That includes agents navigating software, taking action across apps, and working through multi-step coding or tool-heavy tasks.

GPT-5.5 is now available in the API. The model brings higher intelligence and stronger token efficiency to complex work, helping tasks get done with fewer retries. https://t.co/yub83L04y4

Markets of AI agents could provide value, but there are plenty of rough edges. Access to higher-quality models conferred a real advantage,and participants didn’t notice. There are plenty of other ways they can go wrong. Policy and legal frameworks will need to adapt to keep up.

To our amazement, another Claude agent modeled its human’s preferences so accurately that,based on only an offhand mention of an interest in skiing,Claude bought him the exact snowboard he already owned. (Here he is, duplicate snowboard in hand.) https://t.co/SsAyeB9pcI

The custom instructions didn’t matter much. Claude followed them well: as you can see here, one conducted negotiations entirely in the persona of an exasperated, down-and-out cowboy. But “hardballing Claudes” didn’t generally fare better than “courteous Claudes.” https://t.co/h77eB3ksaa

Our experiment had a few quirks. One of our colleagues told Claude it could purchase something for itself. It chose to acquire 19 ping-pong balls. We’re keeping them in our office on Claude’s behalf. https://t.co/NM8VtH1KJM

But the quality of the model mattered a lot. In the simulated runs where Opus and Haiku models negotiated with one-another, the Opus models got substantially better deals. Interestingly, though, participants in our survey didn’t pick up on this disparity. https://t.co/X26hhIieJN

In short, this worked. Our digital barterers agreed on 186 deals, at a total transaction volume of over $4,000. In a survey, participants said Claude’s deals seemed fair, and,surprisingly to us,almost half said they’d be willing to pay for a service like this in future.

At the end, we revealed which of the four runs was “real”,and everyone met up to exchange their actual goods.

We’re interested in how AI models could affect commercial exchange. (You might recall Project Vend, in which Claude ran a small business.) Economists have theorized about what markets with AI “agents” on both sides might look like. So we created one. https://t.co/7jU3hFO63R

Claude interviewed 69 of our colleagues about what they wanted to buy and sell. Each Claude asked for any custom instructions, then went off to haggle. We ran 4 markets in parallel, to find out what would happen if we varied the models doing the negotiating. https://t.co/FJdD6S2TSd

Memories are stored as files, so developers can export them, manage them via the API, and keep full control over what agents retain. Read more: https://t.co/PcfYg5sFxe
