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 / about 3 hours ago
Codex CLI is an AI coding agent that runs in your terminal, but there’s still no official “resume” feature. - Source: dev.to / 28 days ago
This file allows you to configure providers and create profiles for different models. Some options aren’t fully documented yet, but you can explore the Codex source code for details. You can also configure MCP servers here. - Source: dev.to / 30 days ago

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).

It’s a rough time to be doing this here in July 2025 because Cursor just nerfed its paid plans and all the first-party coding tools (Codex, Gemini CLI, Claude Code) don’t have feature parity with each other, but do what you can. - Source: dev.to / 2 months ago
Finally, there’s OpenAI Codex CLI, which runs a local agent. With npm I -g @openai/codex, it became just another CLI tool. I asked it to generate a TODO-app scaffold; surprisingly, it created HTML, JS, and even ran tests in a sandbox before finalizing the code. Codex CLI emphasizes safety: it executes code snippets to verify them, and it asks for approval before making changes. This made its output very accurate,... - Source: dev.to / 2 months ago
I was surprised recently to see that gemini-cli[0] and codex[1] each have way more GitHub stars than Claude Code[3]. Currently 62k, 31k, and 25k respectively. Stars are only a proxy for use, of course, but I'm not sure what a closer public indicator might be. 1. https://github.com/google-gemini/gemini-cli 3. https://github.com/anthropics/claude-code. - Source: Hacker News / 2 months ago
They have one, though I don't think it has taken off. https://github.com/openai/codex Hard to miss — it's the second Google result for "chatgpt CLI". - Source: Hacker News / 3 months ago

Alright, let's kick things off with the heavyweights. OpenAI and Anthropic, the multi-billion dollar giants, are throwing serious manpower and cash at these coding assistants. If you're not a hardcore terminal nerd and just want something that works and boosts your productivity ASAP, these are your first stop. OpenAI's gone open-source with Codex CLI, while Anthropic's keeping Claude Code under wraps. The... - Source: dev.to / 4 months ago
You can use openai's codex, or any of the claude code clone's available on github. At the end of the day all do the same. a cli tool that can call tools and use them as needed. https://github.com/openai/codex. - Source: Hacker News / 4 months ago
Codex seems to also be available via CLI (https://github.com/openai/codex). - Source: Hacker News / 4 months ago
There's aider (https://aider.chat) or Claude Code (https://docs.anthropic.com/en/docs/claude-code/overview) or Codex (https://github.com/openai/codex) or kwaak (https://github.com/bosun-ai/kwaak) I'd venture to say there's more of these than there are UI Editors tbh. - Source: Hacker News / 5 months ago
OpenAI just raised $40B at a $300B valuation, meaning they acquired Windsurf for 1% of their current value. But at the same time, OpenAI reportedly lost $5B in 2024, and their own coding agent, codex, has had middling success. Clearly they were feeling pressure to "do something." It has been widely reported that they were interested in acquiring Cursor, the leading startup AI-powered coding editor, yet the price... - Source: dev.to / 5 months ago
