Show HN: Open-source coding assistant with terminal access (docs.sweep.dev)

52 points by martinye022 ↗ HN
Sweep is an AI coding assistant that reads your files and runs code in your terminal. It takes a list of files and instructions, and performs edits using GPT4. For example, you can tell Sweep to reference a.tsx to localize b.tsx.

We previously worked on Sweep as a bot that generated pull requests from GitHub issues. We learned that AI needs validation (like formatters and unit tests) to code properly. We tried setting up a code sandbox for each user but this didn't work well. We’re now relying on the prebuilt dev environment on their machine to avoid having to install dependencies.

LLM based pipelines are also error-prone. Our previous project was a pipeline that turns the issue into relevant files as context, relevant files to a generated plan of files to change, and then the generated plan to a series of code changes. It’s frustrating when one/all of these steps fail and you’re forced to start over. You can now intervene at each step, making the entire process more reliable.

Sweep is open source (licensed under AGPL) and runs entirely on your laptop. The only remote calls will be to OpenAI. We'd love to help you perform software chores like version upgrades, where you describe a set of changes to have Sweep apply over multiple files. You can install Sweep here with a one-line command: https://docs.sweep.dev/assistant. We'd love to hear any feedback you have!

Local LLM support? (Llama/Ollama)
okwhateverdude
Ollama folks just announced api compat with openai's stuff

https://ollama.ai/blog/openai-compatibility

So apparently, yeah.

Would be nice if rather than adhering to a specific very-closed source company first things were developed for standards, or at least used something like litellm.

It probably makes it easier for many companies to move off of OpenAI since they won’t need to drastically alter their codebase.

We have tried many of the current open source models but unfortunately the only model whose capability is close to GPT-4 is Deepseek and unfortunately Deepseek can’t follow our specified format and is very sensitive to prompt changes.

The other problem is with latency: Deepseek 34B on A100s seem slower than GPT-4 but perhaps it will be better on H100s.

It's interesting that you're moving from a "cloud/batch" approach based on GitHub issues and PRs to more of a "local/batch" approach. It seems that this new version of sweep still is sort of agentic and sends GPT off to iterate on a highly specified task until some pre-written tests pass?

As a contrast, aider [0] has always been focused on a "local/interactive" ai coding model. It lets you "pair program" with GPT-4, within your existing git repo code base.

You can give GPT fairly short, informal instructions and you see GPT's code edits stream back in real time. If you see that it has misunderstood, you can interrupt or undo the edit and offer more direction. This feels potentially more efficient than very carefully specifying the task up front, pre-writing the tests, firing off a long agentic job ... and then finding out 20 minutes later that your instructions weren't clear enough.

Have you considered a more interactive approach?

The new Sweep assistant is also interactive! You can request for a plan, approve the plan to have Sweep run through each of the proposed files to edit. We found that it was really difficult to iterate with an agent that only responds every 20 min.

I am not sure. I pretty much stopped using aider, to switch to chatting with GPT-4 directly. I don’t yet have a great meta-framework for coding this way, but I think it’s more agentic than interactive.

If I had to describe my current process, it would be to 1) brainstorm approaches 2) create a toy implementation 3) integrate solution into project. Each of these steps is interactive. For brainstorming, I’ll usually have it create the simplest implementation, check it by eye only, and if it’s on the right track I will begin adding constraints to make it more realistic. If it isn’t, throw away the conversation and start from a new prompt (don’t bother trying to get it to recognize its mistakes if they are categorical) Finally, if I’m feeling lazy, I will ask it to integrate this snippet into the real project (typically this is the first point GOT sees my actual code, and it’s just doing the mechanical transformation between the snippets).

To automate the workflow that I’m talking about does require a more agentic approach than just a chat interface provides. I guess the answer is probably in the middle somewhere.

Okay, so like...the part of this that's actually interesting is the part that doesn't run on my laptop, and instead requires handing my source code to an untrustworthy third party?

I have to agree, I'm tired of getting baited into looking at these projects.

In our benchmarks, open source models still have a long way to go (just breaking past the GPT 3.5 barrier now). We're excited to move to open source models when they're ready, but right now they simply aren't there yet.

Even when they are, it'll still be a while before you can run such a powerful model on your laptop. Thanks for the feedback!
