  • Pairing with Claude Code to rebuild my startup's website
    I just started using aider, recommend it: https://aider.chat/ It indexes files in your repo, but you can control which specific files to include when prompting and keep it very limited/controlled. - Source: Hacker News / 11 days ago
  • We built an open-source asynchronous coding agent
    Aider and Goose are also open source. Goose is backed by a big company, but Aider isn't and was one of the first (that I know of at least). https://aider.chat/ https://block.github.io/goose/. - Source: Hacker News / about 2 months ago

    Feels very similar to Aider[1] 1: https://aider.chat/. - Source: Hacker News / 2 months ago
  • CLI vs IDE Coding Agents: Choose the Right One for 10x Productivity!
    I also tried Aider, an open-source Python CLI agent. It installed via pip install aider-install and gave me an aider command to use anywhere. Aider stands out for flexibility: it supports 100+ languages and multiple LLMs, and it even shows token usage after each session. In practice, Aider automatically committed code changes and ran linters/tests after edits, which was handy for catching mistakes. It wasnโ€™t as... - Source: dev.to / 2 months ago

  • Building a Rust API with Claude Sonnet 4.5
    Sonnet has proven itself to be very powerful and capable of handling complex tasks, but lately the community were claiming that Claude is slowly getting worse and it's not as good as it first was. This is especially after OpenAI released their leading coding model Codex model for their open source Codex CLI. - Source: dev.to / 3 days ago
  • No โ€œresumeโ€ in Codex CLI, so I built one: quickly โ€œcontinueโ€ with `codex-history-list`
    Codex CLI is an AI coding agent that runs in your terminal, but thereโ€™s still no official โ€œresumeโ€ feature. - Source: dev.to / about 1 month ago
  • Codex CLI: Running GPT-OSS and Local Coding Models with Ollama, LM Studio, and MLX
    This file allows you to configure providers and create profiles for different models. Some options arenโ€™t fully documented yet, but you can explore the Codex source code for details. You can also configure MCP servers here. - Source: dev.to / about 1 month ago

  • OpenAI Open Models
    Inference in Python uses harmony [1] (for request and response format) which is written in Rust with Python bindings. Another OpenAI's Rust libraries is tiktoken [2], used for all tokenization and detokenization. OpenAI Codex [3] is also written in Rust. It looks like OpenAI is increasingly adopting Rust (at least for inference).
