Best AI coding harnesses

Of course you're gonna end up with better code. So build that into your process. Pick one of the agents to drive with. I've mainly been driving with Claude, which is actually interesting because I have some other reservations about Anthropic. But the reason I'm sticking with Claude is, in my opinion, they actually have the best harness. And one of the reasons it's the best harness is it's multi-agent running. So if you wanna run multiple agents at the same time, you can do arrow left when you're inside a session, then it goes back to Agent View. And here in Agent View, you can pick up another agent. So if you wanna do this thing where you have multiple threads going on-... the Claude Code is just the nicest setup. They also just, they keep being a little further ahead, which probably shouldn't be surprising. I mean, Boris is one of the guys that's working on that, he was the first one and basically came up with the thing. It's just interesting that that has been an enduring advantage. I've also used OpenCode a lot. I think OpenCode is great. I use OpenCode mainly as my main harness for all the open models, so Kimi K3 and so forth. And I inference not on the Chinese servers. So I inference on Fireworks-... which is a really nice service where you can just pay by the token, and if you're using these open weight models, they're not that expensive by token. So that's a great way to do that. But I don't think I would be using... Well, maybe I would. But if...

Using Claude with a subscription does feel like a bargain, like a crazy bargain.

I just signed up for my second one this morning-... because I got up at 4:00 with jet lag, and I started working with the agents right away, and now I'm three days away from limits resetting on Fable, and I ran out of tokens.

`2:41:22`

I mean, I don't... Why is that so complicated? Can't you just stack one subscription? Why do I need to log in multiple times?

`2:41:33`

Oh, we're building that into Omarchy, by the way. So the next version of Omarchy is gonna ship with multi-sub support. I wish that the labs would just make you buy a max 100 times.

`2:41:57`

Yes. That's actually the deal. The deal with Grok is that their fast mode is cheaper than the regular mode on the others. And when you've used Grok 46 on fast, it's kind of addictive 'cause it almost gets you to this single thread mode-... where the agent is able to keep up with you.

By the way, one of the reasons why I'm not sure what the final form of these harnesses is gonna take, because one of the things we've started experimenting with at Base Camp is that we put the agents inside of Base Camp, and we treat them as coworkers.
