Used it for a quick writing task and it kept the tone consistent without me having to repeat myself, which honestly surprised me.

Used Claude to draft a tricky client email and it actually got the tone right on the first try, which surprised me.

Already a fan! The research that it can do and the precision of the facts is what I like.

People are switching from OpenAI to Claude following Sam Altman's announcement today.

TL;DR: Anthropic refused to sign a contract with the Pentagon that would have allowed the U.S. military to use all of its models without restrictions. Anthropic insisted on an exception, and brace yourself, that its models cannot be used: 1) for mass surveillance of citizens, 2) for autonomous killing. Now the administration is threatening that if the founder of Anthropic doesn't change his mind by a certain date, they will come after him.

Google, OpenAI, and Musk (Grok) have all signed the contract.

Following Sam Altman's announcement over the past few hours, people have been speaking out massively about cancelling their OpenAI subscriptions and subscribing to Claude.

What's the best AI model for coding?

New AI models pop up every week. Some developer tools like @Cursor, @Zed, and @Kilo Code let you choose between different models, while more opinionated products like @Amp and @Tonkotsu default to 1 model.

Curious what the community recommends for coding tasks? Any preferences?

Anthropic raises $65B in Series H funding at $965B post-money valuation

That's a lot of AGI, with some substantial firepower:

Anthropic has raised $65 billion in Series H funding led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the company at $965 billion post-money.

From Coatue, who lead the round:

...what s changed since three months ago (the last round was only three months ago, believe it or not)?

Three things:

We ve seen the shift from co-pilots that help make us more efficient to agents actually doing long-form work tasks on our behalf. This has meant an explosion in both productivity and ROI for customers.

Anthropic introduced Mythos Preview, a whole new model class that demonstrates a step change in intelligence level as seen in the METR chart below. It not only shows dramatic improvement to coding and long-running agents, it is also defining a new frontier for security.

And finally > use cases spreading from coding to everything else.

Pricing

While it has a lot of merits, I'd like Claude to be more transparent about what it thinks I need regarding subscription plan. Instead of a trial-and-error process, it would be helpful for Claude to estimate what is required and suggest which level of subscription I should get on. Having used Claude for a few months now, I believe there is enough data for Claude to make suggestions.

I'd happily accept the risk that Claude over-estimates my credit needs, rather than having to guess – only to hit a wall when you're in the flow.

Onboarding

There is a lot of discussion about how Claude works differently than ChatGPT and other platforms. For ease of migration, it's worth considering having some of those differences (and how a user should adapt) be part of the UI – instead of only living in the docs.
