Https://opencode.ai/ OpenCode was the first agent harness I used, and I have always like it. You can configure a wide variety of providers, but it's open source and has a number of core contributors. The other opinionated option is Pi (the Pi agent harness). This is a great lightweight option and also supports a number of providers. You can also use local model servers. - Source: Hacker News / 9 days ago

OpenCode with GLM 5.2 wrote custom Emacs Lisp to pinpoint within the file where the missing or extra bracket could be. It rewrote the custom code to check various parts of the file. Each of those is a tool use and many, many tokens burned. The next step is to turn those custom scripts written by the AI agent into a tool to speed up the process, or a skill that shows how to use other tools to speed up the process. - Source: dev.to / 12 days ago

I gave GLM-4.5-Air (106B, open weights) 12 coding tasks through opencode on my RTX 3090. It scored 0% — never edited a single file. - Source: dev.to / 13 days ago

Set up your stations. I work in two Ghostty terminals. The left side is for planning and viewing, the right for synchronous agents running through OpenCode. - Source: dev.to / 21 days ago

If you want to try it yourself: grab OpenCode, point it at OpenRouter, select GLM 5.2, and give it a real task instead of a benchmark. The z.ai docs have the rest of the details. - Source: dev.to / 22 days ago

Fine-tuned models often excel in tasks that require strict adherence to structure or formal constraints. For example, Cosine, which is an AI software engineering assistant that’s able to autonomously resolve bugs and build features, was able to achieve a SOTA score of 43.8% on the SWE-bench⁠ verified benchmark. - Source: dev.to / about 2 months ago

Cosine (and the Genie assistant) helped by scoping the problem, writing clean Python code, setting up the GitHub workflow, and documenting every step. That eliminated setup friction and prevented common pitfalls (e.g., token handling, chat ID discovery, state management). - Source: dev.to / 10 months ago

I’ve used AI to brainstorm app features, like a real-time chat tool, and it suggested integrations I hadn’t considered. In 2025, generative AI can draft wireframes or write unit tests, freeing you to focus on design (these days I’m building a Sudoku game with cosine.sh and the AI gave me some ideas I didn’t think of!). Use the AI to push your limits and see where it takes you! - Source: dev.to / 11 months ago
