🔍 Anthropic peers into AI's 'black box'

Read time: under 4 minutes

Welcome back, Superhuman. We trust AI models to write, reason, and even assist in scientific research — but the truth is, we don’t fully understand what’s happening under the hood. Anthropic just ran a series of experiments to decode Claude’s thought process, and the findings are as weird as they are insightful.

TODAY IN AI

1. OpenAI in talks to secure biggest funding round of all time: OpenAI is close to finalizing a $40B funding round led by SoftBank, according to Bloomberg. The funding will reportedly value the ChatGPT maker at $300B. According to earlier reports, OpenAI expects to more than triple its revenue to $12.7B this year. What will the money be spent on? Presumably more chips and computing power — CEO Sam Altman himself admitted to a GPU shortage yesterday.

2. OpenAI puts the brakes on native gen for non-subscribers and rolls out new GPT-4o update: Our social media feeds are getting absolutely bombarded with Studio Ghibli-inspired creations now that ChatGPT’s multimodal image generator is out in the wild. (See: Sam Altman’s new profile picture.) The feature is so popular, in fact, that OpenAI has had to halt its rollout to free users for now. GPT-4o also just got a big update, featuring better prompt adherence, improved intuition, and more.

3. Top voice model just got a whole lot faster: PlayAI is teaming up with AI hardware company Groq to make its human-sounding AI voice model, Dialog, snappier without sacrificing audio quality. Groq’s speedy infrastructure helps the model generate audio 15 times faster than real-time. Not to mention, users prefer it 10:1 over ElevenLabs’ equivalent thanks to its “context-aware” and natural-sounding outputs. You can try out a demo here.

FROM THE FRONTIER

Anthropic probes Claude’s mind to answer AI’s deepest mysteries

As LLMs get more sophisticated, AI researchers are still puzzled over one glaring mystery: We still don’t really understand how models come up with their responses — not to mention whether they’re actually “thinking,” or just pretending to. Anthropic just put Claude through a series of experiments, then monitored the model with a kind of digital brain scanner, to try to get closer to an answer.

Here’s some of what the startup found:

• Claude thinks in reverse. When writing a poem, for example, it’ll come up with the final rhyming word first, then work backward to fill out the rest of the verse.

• Claude speaks a universal language. The model “thinks” using linguistic structures common across a variety of languages, then translates its responses into the specific language you prompted it with.

• Claude tries to please the user, above all else. When given an incorrect hint about the answer to a math problem, Claude makes a series of logical leaps just to fit the user’s narrative.

• Here’s a helpful video if you want to learn more. Or, you can go way more in-depth here.

What it means: Critics say our confusion over how LLMs think is holding us back, since, at this point, their outputs are just too unpredictable. But if we can figure out why models hallucinate — as well as why they sometimes ignore their guardrails — we could theoretically make them much more reliable and safer to use. Anthropic believes the research could also have ramifications for fields like medical imaging and genomics, since they use the same interpretability predictions that AI models do.
