Analysis of CodeHerald

Overall verdict

  • Conflux Release: A Spec-Driven Orchestrator for Parallel AI Development
    Tools like Claude Code, Codex, and OpenCode have made โ€œwriting codeโ€ itself much easier. But in real development, the harder problems are different: how to keep the specification in front, how to run multiple changes safely in parallel, and where to place acceptance judgment. - Source: dev.to / 5 months ago
  • How to choose your coding assistants
    Coding assistants like Cursor, Windsurf, Claude Code, Gemini CLI, Codex, Aider, OpenCode, JetBrains AI etc. Have been making the news for the last few months. Yet, the choice of tools is a lot harder and limited for some of us than it seems. - Source: dev.to / 8 months ago
  • Using Jest and LLM assistance to test your real-time chat
    The following segments are specific to GitHub co-pilot but similar concepts apply to other LLM tools such as GPT codex, Claude (which would be similar to Claude skills) and on a limited level, Junie too. We will explore two methods of reusing the prompts / instructions. Both methods will have their instructions written in Markdown format, specifically the CommonMark. These files have their extension as .md. They... - Source: dev.to / 11 months ago
  • OpenAI Codex Review
    > incorrect, its an o3 finetune. This is Open AI's fault (and literally every AI company is guilty of the same horrid naming schemes). Codex was an old model based on GPT-3, but then they reused the same name for both their Codex CLI and this Codex tool... I mean, just look at the updates to their own blog post, I can see why people are confused. https://openai.com/index/openai-codex/. - Source: Hacker News / over 1 year ago
  • OpenAI o3 and o4-mini โ€“ OpenAI
    The big step function here seems to be RL on tool calling. Claude 3.7/3.5 are the only models that seem to be able to handle "pure agent" usecases well (agent in a loop, not in an agentic workflow scaffold[0]). OpenAI has made a bet on reasoning models as the core to a purely agentic loop, but it hasn't worked particularly well yet (in my own tests, though folks have hacked a Claude Code workaround[1]). o3-mini... - Source: Hacker News / over 1 year ago
