I have been using @DevinAI almost exclusively for the past few months, so when I say I genuinely believe it's in a completely different class than tools like Claude Code, Codex, or Cursor, its for good reason.
People always ask what makes it different.
My answer is that Cognition seems 100% focused on one thing: building the best AI agent that can handle end-to-end engineering.
You can hand Devin an entire feature and literally "let it cook". Hours later it'll come back with a PR, a screen recording of what it changed, CI already handled, and any review feedback addressed.
I do have two BIG complaints, though.
Firstly, for more "interactive" development, Devin can be pretty slow.
Secondly, you may need to take out a second mortgage to pay for tokens.
Today they released Fusion.
Now I have zero complaints.
Went to Claude Build Day with @AnthropicAI and @cerebral_valley last week. Built something real. Shipped it the same day. Walked out a sharper builder than I walked in.
We launched Launch Control at the event, the first open-source drop from Paradigm. We took the distribution engine behind Parry and made it public.
One click. Every platform. Content built to win.
Here's what it actually does:
→ Researches your market and becomes a domain expert on what you're launching
→ Studies each platform's API to find what's winning right now
→ Runs sub-agents that argue over your content so only the strongest ideas survive
→ Reviews every video scene by scene and regenerates what looks off
→ Posts everywhere for you. X, LinkedIn, IG, TikTok. Even spins up your Luma page.
We couldn't get our hands on Fable 5, but honestly that pushed us harder. We ran the entire thing on Opus 4.8 and that model is on another level. The reasoning, the instruction following, the way it holds a complex build in its head without dropping a thread. It is the best model we have ever shipped on, full stop. We even open-sourced our own Claude Code skill, Claude Classroom, to squeeze even more out of it. It's in the repo.
Anthropic put on a day that genuinely made us better. That's rare.
Huge thanks to @sarahzorah for making it happen.
