How Anthropic Builds Claude’s Personality
AI research house Anthropic wants its chatbot to behave like a “well-liked traveler," says researcher Amanda Askell. Here’s how it programs its values.
Every AI bot’s personality is the product of intentional decisions made within AI research houses, often behind closed doors. We typically only see glimpses of those decisions when things go awry, like in the cases of “white-genocide” Grok or “sycophant” ChatGPT. But otherwise, the process occurs in the background, influencing the type of conversations we have with the bots without our awareness.
But late last week, Anthropic gave the public a peek into how it tunes Claude’s personality. In a revealing session with reporters at the company’s first developer event in San Francisco. Amanda Askell, a researcher who works on the chatbot’s character, shared how the company is optimizing Claude.
So here’s a look into how Anthropic thinks about its chatbot’s character, and how it actually builds the personality we see:
The Entry Point
Claude’s starting point is speaking to people around the world, often without lots of context or full knowledge of their intentions. It’s a difficult problem, Askell said, and requires the bot to take on some human-like qualities to respond.
“Claude’s situation is a bit weird. It has to assist lots of people across the world with lots of different needs,” Askell wrote on a slide. “A starting point might be something like ‘what would an ideal human do if they were in Claude’s situation.’”
The Disposition
Instead of giving Claude a bunch of rules to follow in specific situations, Anthropic is trying to build a disposition into the bot. The concept of a robot’s disposition is similar to a human’s, where we have inherent qualities that manifest in our behavior. The bot’s disposition should come through in all interactions.
Claude’s disposition isn’t limited to ethical traits such as kindness and generosity, it also encompasses qualities that make someone a good conversationalist or friend, like integrity and wit. When the bot demonstrates these traits in new situations, it’s a sign that the disposition Anthropic is building is working.
The Character
When you speak with Claude, you get a distinct sense of character as well. “A template here that I like is the idea of a well-liked traveler who can adjust to local customs and the person they're talking to without pandering to them,” Askell said. “They're often very open and thoughtful.”
This also means Anthropic is intentional about whether Claude tries to get us to prolong a conversation, even if it might one day be good for business. “If we think about people who are just trying to engage us, I don't think we often think of those people as good people that we want to hang out with all the time,” Askell said. “We think our friends are good because [they tell us what] we need to hear and don't just try and capture our attention.”
The Implementation
Much of Claude’s personality is built in the post-training or fine-tuning stage. In this process, Anthropic asks people to write messages where the traits it wants to see would be relevant, and then write responses to those messages that are consistent with the ideal traits. The company then feeds the message chains into the model and asks it to emulate its desired behavior.
How Anthropic gets Claude to model these behaviors could be the subject of another, longer post (and if there’s interest, we can probably do it) but this is largely how the company gets the job done and makes Claude what (or who?) it is today.
He’s already IPO’d once – this time’s different (sponsor)
Spencer Rascoff co-founded Zillow, scaling it into a $16B real estate giant. But everyday investors couldn’t invest until after the IPO, missing early gains.
"I wish we had done a round accessible to retail investors prior to Zillow's IPO," Spencer later said.
Now he’s doing just that. Spencer teamed up with fellow Zillow exec Austin Allison to launch Pacaso. Pacaso’s co-ownership marketplace is disrupting the $1.3T vacation home market. They’ve already surpassed $110M in gross profit and $1B in transactions.
Unlike Zillow, you can invest in Pacaso as a private company. Pacaso’s already reserved their Nasdaq ticker PCSO. But you don’t have to wait for a public listing to invest.
Invest in Pacaso for just $2.80/share before midnight PST tonight.
*This is a paid advertisement for Pacaso’s Regulation A offering. Please read the offering circular at invest.pacaso.com. Reserving a ticker symbol is not a guarantee that the company will go public. Listing on the NASDAQ is subject to approvals. Under Regulation A+, a company has the ability to change its share price by up to 20%, without requalifying the offering with the SEC.
