Codex
OpenAI Open Source Programming Agent
The local programming agent launched by OpenAI can understand codebases in the terminal, modify across files, run commands, and debug issues. Configure models and quotas uniformly through the OpenAI Responses compatible interface of Ace Data Cloud.
What is Codex?
Codex is an open-source local programming Agent launched by OpenAI, running in your terminal. It is not just a simple code completion tool, but a true programming agent—you only need to describe the functionality you want in natural language, and Codex can understand the entire codebase, edit code across files, run commands in a sandbox, debug issues, and iterate until the task is complete.
Ace Data Cloud provides a low-cost OpenAI Responses compatible proxy, allowing you to use Codex for less than half the official price. No fixed monthly subscription is required; pay per token usage, with ample quotas, globally available, and ready to use after one-time configuration.
Core Capabilities of Codex
Not just code completion—it's an agent that can understand, edit, execute, and deliver code
Codebase Understanding
Automatically analyzes project structure and dependencies without the need to manually select context files. Just say "explain the directory structure of this project" to get a complete architectural description.
Multi-file Editing
Precise editing across multiple files, not just giving suggestions. Codex understands the relationships between codes, ensuring the correctness and consistency of changes.
Debugging and Fixing
Describe the bug or paste the error message, and Codex will locate the root cause and implement a fix. It can read logs, run tests, and iterate until the issue is resolved.
Command Execution
Run shell commands, run tests, install dependencies, and check Git status in a controlled sandbox, allowing the agent to truly carry out end-to-end development tasks.
MCP Tool Integration
Supports Model Context Protocol, allowing integration with AceData Cloud MCP tools like Suno, Midjourney, SERP, expanding the capabilities of Codex.
Adjustable Reasoning Intensity
Switch between low / medium / high using model_reasoning_effort, allowing the model to think deeply and provide well-considered solutions when facing complex architectural decisions.
model_provider = "acedatacloud" model = "gpt-5" [model_providers.acedatacloud] name = "Ace Data Cloud" base_url = "https://api.acedata.cloud/v1" env_key = "ACEDATACLOUD_API_KEY" wire_api = "responses"

Frequently Asked Questions
Everything you need to know about using Codex through AceData Cloud
What is the relationship between Codex and the OpenAI API? ▾
Codex is an open-source command-line programming agent launched by OpenAI, which communicates with the model through the OpenAI Responses API at its core. AceData Cloud provides a proxy service compatible with OpenAI Responses, and Codex can use our service by configuring a custom model_provider in ~/.codex/config.toml, with functionality fully consistent with the official version.
What are the advantages of using AceData Cloud? ▾
Three main advantages: (1) Lower cost—charged based on token usage, at less than half the official price, with no fixed monthly fee; (2) Ample quota—unlike the official subscription, there are no quota prompts, and high-frequency usage is not throttled; (3) Globally available—regardless of your location, you can use it stably and with low latency.
Which models are supported? ▾
Supports the entire range of GPT-5 models, including GPT-5, GPT-5 mini, GPT-5 nano, etc. You can specify the default model in the model field of ~/.codex/config.toml, or switch using the /model command in the Codex interactive interface. We will follow up promptly after OpenAI releases new models.
How to configure Codex to use AceData Cloud? ▾
Declare model_provider = "acedatacloud" in ~/.codex/config.toml, and set base_url = "https://api.acedata.cloud/v1", env_key = "ACEDATACLOUD_API_KEY", and wire_api = "responses" under [model_providers.acedatacloud]. Please refer to the configuration tutorial for detailed steps.
On which platforms is it supported? ▾
Coding Plan currently provides an entry for Codex CLI configuration, connecting to the OpenAI Responses compatible interface through model_provider.
How to verify if the configuration is effective? ▾
After completing the configuration, run codex to enter the interactive interface, and input /model to check if the current model and provider are from acedatacloud. You can also check the API call records and usage statistics in the Ace Data Cloud console to confirm that the requests have been sent through the proxy.
Is it available worldwide? ▾
Yes. AceData Cloud provides access nodes that are available globally, allowing you to use Codex with stability and low latency, no matter where you are. No need for a VPN, no need for an overseas credit card, just register to use.
