Anthropic claims that the new Claude Sonnet 4.5 is the best model for building agents. Their benchmarks show it to be better than gpt-5 at tool use and also computer use. Not surprising tbh, Claude models have always been good at agentic tool use as they don’t get lazy.

Computer use is exciting (if it is reliable) because it unlocks some use cases that has actual economic value.

All these AI companies should go and rest abeg. Always releasing one rubbish or the other, just to remain in the news.

It made front page and should be an informative topic. Sadly, like many others, I have nothing to comment. I understand the write-up but have no interest in the subject.

So Oga Seun knows what AI is, but refuses to use algorithm for the front-page (FP). Why should everyone have the same FP in 2025?

Those that love politics should see more political Threads on their FP, while those that engage romance forum should see the top Threads there. Everyone can then see trending/promoted Threads.

Instead of hiding the signature of the loyal Nairalanders (content creators), the visitors (those without accounts) should be limited by the number of pages they can view. This would give people the incentive to engage the site more.

It's really slow for Mathematical use. And it's need to work on Visual reasoning.

Which Claude plan are you on? I'm on the $20 plan. I mostly use it to write prompts with Claude Opus in the browser. I rarely use Claude Code.

Same as you but sometimes I go about using the free tier of other LLMs when I don't want to subscribe
