Codex vs. Ask Codi

Codex is OpenAI’s agentic coding partner built to accelerate real engineering work end-to-end, helping you plan, implement features, refactor, review, and ship releases while fitting into the tools and workflows developers already use. Rather than acting like a chat-only assistant, it’s positioned as a “build with agents” experience that can take on substantive tasks (and context) across a codebase so you spend less time on repetitive execution and more time on decisions, design, and quality.

We provide an OpenAI-compatible orchestration layer that lets teams compose their own “virtual models” on top of any LLM - combining prompts, reasoning, review, and guardrails, and use them everywhere, from your IDE to your backend. Key features: 1. One OpenAI-compatible API for many LLMs 2. Custom models you name & reuse 3. Reasoning mode on demand 4. Built-in review mode 5. Guardrails & PII masking 6. IDE & CLI integrations 7. Analytics & cost controls.
