  • The best free ChatGPT alternatives
    I saw a post earlier this week saying that they feel the outputs from ChatGPT have been declining, and a lot of people agreed. There are a good amount of quality AI chat alternatives out there besides ChatGPT and some even offer GPT-4 for free! Here's a list of alternative chatbots to try out (I've tried all of these not some bs list): Perplexity: "The first conversational search engine" (GPT-3.5 Free / GPT-4... Source: about 3 years ago

  • ZCode: Claude Code from the Makers of GLM
    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 / about 23 hours ago
  • AI for Less Popular Programming Languages
    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 / 4 days ago
  • How to Run Reliable Local LLM Agents on an RTX 3090: A Benchmark (5 Models, Priced in Watts)
    I gave GLM-4.5-Air (106B, open weights) 12 coding tasks through opencode on my RTX 3090. It scored 0% โ€” never edited a single file. - Source: dev.to / 5 days ago
  • The head chef model of AI collaboration
    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 / 13 days ago
  • Testing GLM-5.2 on OpenCode: I'm impressed!
    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 / 14 days ago
