Project mention: How to Use an AI Agent — Build a Working Agent Team in Three Steps | dev.to | 2026-06-12
How do you use an AI Agent? Three steps: pick a platform → define the Agent → run and iterate. The core formula — define the role, set the goal, connect the tools, draw the red lines. Developers build with LangChain; non-technical teams drag and drop on SoloEngine. You can have an Agent up and running in 5 minutes. Tech isn't the barrier — clearly defining your Agent is.

ComfyUI
The most powerful and modular diffusion model GUI, api and backend with a graph/nodes interface.
So I use a combination of Neo Forge and ComfyUI. Forge has an easier learning curve but ComfyUI gets all the new "hotness" almost immediately since there's so much custom nodes for it.
If you're on a Mac, I've heard that Draw Things is supposed to be pretty "batteries included" simple for image gen along the same lines as LM Studio.

Project mention: Tracing torch.cuda.empty_cache() on an RTX 4090 - Where Do the 53 MB Go? | dev.to | 2026-05-28
pytorch/pytorch#173382 - a user calls torch.cuda.empty_cache() after deleting tensors, but GPU memory stays allocated. The caching allocator's empty_cache() only releases blocks it has marked as free, but the user sees a persistent gap between "allocated" and "reserved" memory. We traced what happens when torch cuda empty cache runs on an RTX 4090 and measured exactly how much GPU memory it reclaims.

deer-flow
An open-source long-horizon SuperAgent harness that researches, codes, and creates. With the help of sandboxes, memories, tools, skill, subagents and message gateway, it handles different levels of tasks that could take minutes to hours.
Tools have been trending in this direction for the last 3-6 months with features like "Assign to Copilot" in GitHub.com, and the Linear's work tracking system where its unique sales pitch is "write tickets for agents to work on here". The final form of this kind of solution is currently a vague, but there are several projects already pitching to own this space such as Open AI's Symphony project (https://openai.com/index/open-source-codex-orchestration-symphony/), ByteDance's DeerFlow (https://github.com/bytedance/deer-flow) which pitches itself as "an open-source super-agent harness", and other similar projects.
NOTE:
The open source projects on this list are ordered by number of github stars.
The number of mentions indicates repo mentiontions in the last 12 Months or
