Claude users can access more apps with Anthropic's AI now thanks to new connectors for everything from hiking to grocery shopping. Anthropic already supported connecting numerous work-related apps to Claude, like Microsoft apps, but this expansion focuses on personal apps like Audible, Spotify, Uber, AllTrails, TripAdvisor, Instacart, TurboTax, and others. Some of these apps, such as Spotify, already have similar connectors in OpenAI's ChatGPT. Once an app is connected, Claude will suggest relevant connected apps directly in your conversations, like using AllTrails for hike recommendations. A...

Anthropic's tightly controlled rollout of Claude Mythos has taken an awkward turn. After spending weeks insisting the AI model is so capable at cybersecurity that it is too dangerous to release publicly, it appears the model fell into the wrong hands anyway. According to Bloomberg, a "small group of unauthorized users" has had access to Mythos - whose existence was first revealed in a leak - since the day Anthropic announced plans to offer it to a select group of companies for testing. Anthropic says it is investigating. That's a rough look for a company that has built its brand on taking AI ...

Usually the Claude session window always starts and ends on the full hour but today I just noticed it's not matching up with the full hour. Another small change is they removed the refresh button from their UI so you can't see your real-time usage without refreshing the whole page. Is this happening for everyone else? Are they changing some things about their usage limits?

Earlier this month, millions of OpenClaw users woke up to a sweeping mandate: The viral AI agent tool, which this year took the worldwide tech industry by storm, had been severely restricted by Anthropic. Anthropic, like other leading AI labs, was under immense pressure to lessen the strain on its systems and start turning a profit. So if the users wanted its Claude AI to power their popular agents, they'd have to start paying handsomely for the privilege.

So we all got that extra credit a few weeks back, right? $150 in my case. I turned off extra usage until I needed it, which is today. Tried to call the API - no balance. So the extra usage is only via claude code. Thanks for that, Anthropic. EDIT: So I added $25 in API usage, and the text against that balance says: "Your credit balance will be consumed with **API, Claude Code** and Workbench usage. " Jesus wept, Anthropic. Do you seriously ever get someone to sit and think about what you're doing?
