Fully agree that in the end sandboxes are required to get frontier performance out of the models. But you can have both: rund the agent outside the vm/sandbox and orchestrate work …

All the power to you, and I hope Pi will be able to continue its unified layer. However, there is an alternative: model the session fully in the provider native structures, extract…

Yes, I agree with your point and article regarding hidden or sealed state. So, I'm aware that this is a separate point from the article, and I'm well aware of Pi's model abstractio…

Fair. But in the background of the article is clearly the goal to make sessions portable, not just being able to inspect it. It's partially implied even in the title. There is just…

I think there are two things going on more generally: 1) providers increasingly adding hidden state that the user or developer cannot inspect, port, or do anything with. This is cl…

It’s endlessly fascinating to read the AI transcript of an expert who _really_ knows how to cut to the chase. It just shows how much you can potentially squeeze out of these models…

I’m thinking along my similar lines. Expansion, if it happens, will likely not be on a recognizably human substrate, but rather something else. But currently it’s more of an intuit…

A self-hostable Claude Tag or OAI Work [0]. A while ago, I realized that most new agent harnesses being built must be hosted on your machine or on a VM--in other words the agent ne…

Make hay while the sun is out.

Very interesting: I wonder if the RL approach is diverging between Anthropic and OAI? I noticed that Fable uses shell tools almost exclusively (even to search and edit files), comp…

yes, basically people that want to host powerful, long-running agent runs not on dedicated VMs (although lightspeed can use those too), but on an abstraction layer above. My thesis…

I think these kind of semi-coding agents--but hosted--are the future for enterprises. Claude Tag, Claude Cowork, now Work by OAI. Agents-on-your-machine clearly have their place, b…

Oh man, I love capitalism spoiling us here. I was just enjoying my extra Fable credits, now I'll switch to using 5.6 this weekend. I was planning to ration my Anthropic credits, I …

getting downvoted for my other answer. I wasn't clear: yes, there is of course a lot of prior art in pi, and pi specifically does not just store the session events, but adds an abs…

most coding harnesses store the exact messages that have been sent to the llm and the messages items that have come back from the llm, not much else. Then, there is also a set of e…

Very cool. I settled on the same/similar design in my agent harness. All relevant events that affect the context window are stored in an event log. Forking agents and sessions is s…

I work with large enterprises that _only_ run critical workloads on locally hosted models. Think banks, insurance, etc--businesses that absolutely cannot leak any data. They also h…

Agent harness for durable workflows, starting with Temporal. Most agents for durable workflows feel like toy examples. There is no "Codex" or "Claude Code" for, say, Temporal. So I…

Arguably, if your agent needs a lot of custom logic to drive the agent loop it isn't an "agent" at all. At best it is an agentic workflow, or rather a workflow with some LLMs calls…

This is why taking investments too early is usually a mistake. It locks you in to one hand. Of course, you can pivot, but it is much harder with investors looking over your shoulde…

Still one of the best critique of AI agents, even today.

I keep saying this is the single most important article to consider when talking about AI assisted software building. Everyone should read it. The question should always be: is a h…
