Building Subconscious - The brain for long running, flexible, reliable AI agents. Prev: Exited founder | SWE @ Google | @TigerLacrosse
In a few short years, only two skills will matter for software engineers: Taste and Tradeoffs All meaningful code used to be written by humans, but it's not anymore. Today, somewhere between 20-50% of code is generated by AI copilots, and in just a few years virtually all new…
It's a great Sunday to experiment with the Subconscious playground. You can build a custom deep research agent like this in under a minute! Visit subconscious [dot] dev
The magical part of publicly launching is that now, somehow, people reach out to me with feedback, ideas, or excitement. Inbound is magical
If you haven't tried the Subconscious playground, here's a look. I gave the model search tools, asked it to tell me about our research paper, and boom, we have a personalized deep research agent. Took 15 seconds to make.

Promising👇 Keep an eye on this line of work. A recursive & decompositional problem solving approach for mitigating on of the biggest problems of MAS today. The synergy here btw KV cache pruning & a specialized LLM is interesting. Bravo to the team ! 👏
Today we're launching Subconscious: a new platform for building agents with long-horizon reasoning and tool use, backed by MIT research. One API call. Tool use. Context beyond existing limits. If you're building agents, let's talk.
First time I've heard the term AX and get the feeling we'll be hearing it a lot more
there's a quiet shift happening in how we design software. we're moving from UX to AX (agentic experience). traditional UX is screen-centric. you tap a button, product reacts, job done. every session starts from zero. designers pre-plan every path with hard-coded flows. users…

Beyond Context Limits Subconscious Threads for Long-Horizon Reasoning
Just had the go no go moment for our launch. We are live tomorrow morning.
The people that write these big checks know what they're doing. GPUs will be as core to our country as cell towers and railroads.

There is a really fun, really simple, really viral app to be build with this. Idk what but it's coming. Drag and drop custom memes
You can use Flux Kontext LoRAs on @huggingface using @FAL as inference provider
Stack Overflow basically dead, but it is frustrating that recent and hyper specific questions (that many people are running into) don't have an easy answer. When working with new frameworks/tools, Stack Overflow was better. That leads me to believe that OpenAI (and others like…
