OpenAI Codex $25 consumer stack

OpenAI users spent May 13 posting about a consumer coding setup that combined OpenCode Go’s $5 introductory subscription with OpenAI’s $20 ChatGPT Plus plan, framing it as a $25-a-month way to build apps with both open-source and proprietary coding agents. The posts circulated as OpenAI was expanding Codex offers for both individual and business users, including pricing pages that show Codex bundled into ChatGPT plans and a separate enterprise promotion offering two free months for eligible new users. (openai.com) (opencode.ai) The stack described by users is straightforward on paper. OpenCode Go offers access to a pool of open coding models for $5 for the first month and $10 a month after that, while ChatGPT Plus costs $20 a month and includes Codex across the web, CLI, IDE extension and iOS, according to the companies’ pricing pages. ### What exactly are users combining for $25? OpenCode lists Go as a low-cost subscription that gives users access to open-source coding models through an API key. (opencode.ai) Its documentation says the service is in beta and includes usage caps defined in dollar value, with a 5-hour limit of $12 in usage, a weekly limit of $30 and a monthly limit of $60. OpenAI lists Codex as part of ChatGPT Free, Go, Plus, Pro, Business, Edu and Enterprise plans. On the individual pricing page, Plus is priced at $20 a month and includes Codex on the web, in the CLI, in the IDE extension and on iOS, along with access to newer models and the option to extend usage with ChatGPT credits. (opencode.ai) ### What does Codex do inside the OpenAI plan? OpenAI introduced Codex in May 2025 as a cloud-based software engineering agent that can work on multiple tasks in parallel. (opencode.ai) The company said Codex can write features, answer questions about a codebase, fix bugs and propose pull requests for review, with each task running in a separate sandboxed environment preloaded with the user’s repository. The current Codex product page describes the app as a command center for agentic coding with built-in worktrees and cloud environments. (developers.openai.com) OpenAI says the system is designed to handle feature building, refactors, migrations and code review across several surfaces tied to a ChatGPT account. ### What does OpenCode Go add to that setup? OpenCode says Go is meant to provide reliable access to popular open models at lower cost. Its documentation lists models including GLM-5, Kimi K2.6, Qwen3.6 Plus and DeepSeek V4 Pro, and says users can connect the service through OpenCode or use it with another agent. (openai.com) The company’s docs also say actual request counts vary by model, with cheaper models allowing more requests and higher-cost models allowing fewer. (openai.com) That structure helps explain why users described the product as a lightweight companion to a paid Codex plan rather than a direct substitute. That comparison is an inference based on the published pricing and model lists. ### What can be verified about the social-media claims? A May 13 user claim that a $25 stack was powering an app with more than 300 users while consuming less than 10% of credits could not be independently verified from primary sources reviewed for this article. (opencode.ai) Reuters-style confirmation would require direct access to the post, the account, or supporting usage records that were not available in the sourced materials here. The broader pricing claim can be verified. OpenCode’s official materials say Go starts at $5 for the first month, and OpenAI’s official pricing says Codex is included in ChatGPT Plus at $20 a month, which yields a first-month combined price of $25. (opencode.ai) ### What free-switching offer did OpenAI put on the market? OpenAI is running a separate enterprise promotion that says eligible new Codex users can get two months of free Codex usage if they apply within the next 30 days. A public OpenAI form describes the offer as available to eligible enterprise accounts and asks organizations to submit details for routing. OpenAI is also offering business incentives elsewhere in the product. (opencode.ai) A Help Center page says eligible ChatGPT Business workspaces can earn $100 in credits for each new Codex seat that becomes active, up to $500 per workspace, beginning April 2, 2026. May 31, 2026 is the next date on OpenAI’s published Codex pricing page. The company says the temporary doubled usage on the $100 Pro tier runs through that date, while the enterprise free-use form says eligible organizations have 30 days to seek two months of free Codex access.
