Three tools from Hacker News today, covering local image generation, Markdown editing, and agent workflow management.
Bonsai Image: 4B Parameters for Local Image Generation
PrismML recently released Bonsai Image 4B, a 1-bit quantized image generation model. The idea is straightforward: compress the model aggressively so it can run on consumer hardware like MacBooks.
Built on the Flux architecture with only 4B parameters, the generation quality holds up surprisingly well. The HN discussion (282 points) focused on real-world benchmarks — people tested inference speed on Apple M-series chips and found it significantly faster than full-precision models, with much lower memory usage.
For anyone who wants to experiment with AI image generation locally without paying API fees, this is worth a look. Of course, 1-bit quantization comes with some precision loss — whether that's acceptable depends on your use case.
Atomic Editor: Obsidian-Style Preview in the Browser
Atomic Editor is a web-based Markdown editor built on CodeMirror 6, featuring Obsidian-style live preview. Write Markdown on the left, see the rendered output on the right in real time.
It scored 55 points on HN. Commenters noted that selection highlighting isn't fully working yet, but the overall interaction feels solid. For those accustomed to Obsidian who occasionally need to edit Markdown in a browser — writing GitHub READMEs, editing docs — this is a handy tool.
It runs entirely in the frontend with no installation required. Just open the page and start writing.
Ouijit: A Task Manager for Coding Agents
Ouijit is an open-source terminal task manager designed specifically for coding agents like Claude Code and Codex.
The core idea is simple: when agents work on complex tasks, they often need to manage multiple subtasks and switch between terminal sessions. Ouijit provides a CLI interface that agents can call directly to split tasks, track progress, and manage terminal sessions.
It currently supports Claude, Codex, and Pi. If you use these tools for daily coding, Ouijit can help you keep the agent's workflow more organized.
