OpenAI Codex في عام 2026: النماذج، طرق الوصول، التسعير، والقدرات الحقيقية
واجهة برمجة تطبيقات Codex الأصلية لم تعد متاحة. إليك ما يعنيه "Codex" الآن، وأي نماذج GPT‑5.x‑Codex يستخدم، وكيفية الوصول إليها، وما الذي يمكنه تقديمه فعليًا في المستودعات الحقيقية.
Quick verdict on OpenAI Codex now Best for: teams that want an agentic coding environment to run multi-file edits, repo-wide refactors and scripted workflows on top of OpenAI’s latest coding models. Avoid if: you only need inline completions in VS Code or a single editor – GitHub Copilot, Cursor or IDE-native assistants will usually be simpler. If you’re still choosing your stack, look at a broader best AI coding tools shortlist before committing to Codex as your main agent. Starting price: Codex itself does not have a separate per‑token tariff; usage is billed through a mix of included credits in eligible ChatGPT plans and standard OpenAI API model rates when Codex executes API calls on your behalf. Exact prices depend on your ChatGPT plan and the underlying models used, and should be checked on the current ChatGPT and OpenAI API pricing pages. Main strength: agent orchestration over projects: multiple agents, tools and long-running workflows coordinated through a desktop app, web UI, IDE integrations, and CLI. For most founders this sits alongside tools like Claude Code vs Codex and IDE-first editors such as Cursor. Main limitation: cost and limits scale with the underlying models Codex uses; there is no separate low‑tier “legacy Codex” price band published by OpenAI. Model availability and limits depend on your ChatGPT plan, any Codex‑specific credits, and whether you are using Codex via ChatGPT sign‑in or with separate API keys. Where “OpenAI Codex” started vs what it is now The original Codex: a code-focused language model OpenAI first used the Codex name for a dedicated code model in 2021. The research described Codex as a GPT model fine‑tuned on public GitHub code, designed to translate natural language into source code and handle multiple programming languages and frameworks. arXiv GitHub Copilot’s technical preview in mid‑2021 was the first high‑profile product powered by this Codex generation, delivering autocomplete‑style suggestions directly in code editors. GitHub In OpenAI’s API, these models surfaced as endpoints like code-davinci-002 . Deprecation of the original Codex API Those 2021–2022 Codex models have since been deprecated. OpenAI’s current model list for the public API no longer includes code-davinci-002 and similar Codex LMs in its set of current production models. OpenAI Today, there is no separate “Codex” language model line in the API comparable to that first generation. Instead, the Codex brand has moved up a layer. Codex now: a
