Codex
Core Facts
Gemini 4 Argon is fully available to paid users, but the Anti-Gravity feature is limited to Ultra subscribers, and Pro users cannot use it.
The API model identifier for GPT-6 Astra is gpt-6-astra.
Claude Code is an AI programming assistant launched by Anthropic.
Timeline (last 90 days)
MAO是一款在Product Hunt上发布的桌面工具，将Claude Code、Codex、Gemini和Grok置于同一画布上协作。
If a mixed-technology-stack team maintains only `claude.md`, Codex users will not get the instructions.
Codex reads `AGENTS.md` as its instruction file.
Codex and Cursor can directly read the `AGENTS.md` file.
Gradually approaching the requirement through multi-turn dialogue is an effective compensation strategy, but the cost is time; the gap between 23 minutes and 2 minutes is essentially the model capability gap amplified by the number of dialogue turns.
Codex leans more toward developer scenarios, emphasizing the accuracy of code generation and automated execution; WorkBuddy targets ordinary users, emphasizing zero-barrier file operations and daily tasks.
In the demo, the editing step used a model that is "good at writing and cost-efficient," but the specific API and model name cannot be verified in public materials.
In the demo, Codex helped create a dedicated API key for a Mac writing assistant app via a plugin and completed the integration with the OpenAI API.
Teams using coding Agents such as Claude Code and Codex can connect via vercel ai-gateway setup and select a virtual model in each harness's model selector or configuration.
The Agents supported by this plugin include fx, Codex, Claude Code, OpenCode, and Pi.

90%VerifiedCodex excels at tasks such as function-level code completion, module architecture generation, and documentation-to-code conversion.
90%VerifiedOrdinary office workers should prioritize using WorkBuddy to get work done, and only advance to learning Codex when it is no longer sufficient, in order to reduce the learning cost.
80%VerifiedWorkBuddy is positioned as a domestic alternative to Codex.
80%VerifiedWorkBuddy works out of the box without requiring environment configuration or command-line setup, making it beginner-friendly; Codex requires stronger hands-on ability and a programming background.
80%VerifiedDeepSeek Harness is written in TypeScript, and installation requires a Node.js environment (tested with Node.js 24).
80%VerifiedAgents possess a 'plan–execute–feedback' loop capability, can call external tools such as web search, databases, and APIs, and can decompose complex tasks.
80%VerifiedCodex CLI can read local codebases, execute shell commands, edit files, and run tests.
80%VerifiedPass rates of code generation models on benchmarks such as HumanEval jumped from 60% to over 90% between 2024 and 2025
