DeepSeek shipped V4.1-Flash-1017 on saturday and it benchmogs Opus 5 and GPT 5.6 They called it a "minor update" 💀 And there's one simple, free way to make it perform EVEN better... 🧵

That 77% DeepSWE score only cost ~$0.20 a task, which makes for a pretty amusing chart Opus 5 gets 73-74% for over $10, GPT 6 Astra costs $4.43

So don't sleep on Deepseek! Their harness + Flash model together is a great value combo if you want a good level of work for a low price If you want to learn more about Deepseek harness, I covered it here: xitter.cf/itsjack/status/2088989…
Trying out Deepseek's new harness, and wow - so far very impressed. Here's why I found it interesting: Comes with full traceability, basically Chrome's devtools for every agent run....

Shame we didnt catch the move I did before this when I realized how powerful the machine was My recollection is that it was like something out of The Matrix

this is the way to do it
something that keeps bothering me is how some people see slop as something that is happening to them, like they're some kind of helpless bystander powerless to do anything about it excuse me but you are a software engineer, you literally learned how to make sand think and make computers do your bidding?! and now you can't do anything about it? please the 2 things you should know to cut through all the noise: 1. you need to give your agent a way to verify its own work (i just posted about this so won't rehash) 2. your codebase is memory the 2nd is not new either, we have always had lint rules, compilers with good diagnostics and strong type systems, LSPs, etc to help us write better code. there is no difference when agents write the code instead, you just need more of them, and stronger ones. forget rules and skills. you can add those later. yes, your codebase is a form of memory to agents! agents love extending what already exists. so every nit and every annoyance you've ever seen, every mistake and bad pattern you observe from agents, needs to turn into a constraint, or the agents will just keep repeating those same mistakes like a virus in your code. then you keep observing and repeating this process until your codebase is locked down enough that even agents with little context can one shot a high quality PR. an even better direction is to refactor/rewrite your code such that agent anti-patterns become categorically impossible. use type systems to your advantage, use libraries/frameworks that reduce the architectural search space, or heck, create your own framework like we did for grok bot and design high quality primitives and well thought out APIs

Its been great fun giving agents access to some real hardware to test on Screenshot from one of our recent PRs

The cool thing is that this outputs straight looking images because it flashed these calibration cards on the screens to position them

The actual view the webcam gets is this first video here - which is terrible tbh I need to get a better way of positioning these. But from that to this is quite impressive...

I agree and definitely not biased in any way

Can confirm that @bot is a whole lot better now I quit using it - while the product experience is fantastic, the model was really showing its age Now it can handle long running tasks + loses coherence much less than it did before Smart move!
Important note regarding Grok @Bot: Going forward, @SpaceX will use the best back end model for any given task, including Claude Opus 5.5, MidJourney, Suno and other leading APIs. Whatever is most likely to give you the best outcome.
