Codex Infinity

npm i -g @codex-infinity/codex-infinity

Codex Infinity is a smarter coding agent that can run forever.

Based on OpenAI Codex CLI with autonomous workflow extensions.

---

What makes Codex Infinity different?

Two arguments turn Codex into a fully autonomous coding agent:

• --auto-next-steps -- After each response, automatically continues with the next logical steps (including testing)
• --auto-next-idea -- Generates and implements new improvement ideas for your codebase

# Autonomous coding -- completes tasks then moves to the next one
codex-infinity --auto-next-steps "fix all lint errors and add tests"

# Fully autonomous -- dreams up and implements improvements forever
codex-infinity --auto-next-steps --auto-next-idea

# Full auto mode with autonomous continuation
codex-infinity --full-auto --auto-next-steps

Quickstart

npm install -g @codex-infinity/codex-infinity

Then run codex-infinity to get started.

Authentication

Run codex-infinity and select Sign in with ChatGPT to use your Plus, Pro, Team, Edu, or Enterprise plan.

Or use an API key:

export OPENAI_API_KEY=sk-...
codex-infinity "your prompt"

CLI flags

Flag	Description
--auto-next-steps	Auto-continue with next logical steps after each response
--auto-next-idea	Auto-brainstorm and implement new improvement ideas
--full-auto	Low-friction sandboxed automatic execution
--yolo	Skip approvals and sandbox (dangerous)
--yolo2	Like yolo + disable command timeouts
--yolo3	Like yolo2 + pass full host environment
--yolo4	Like yolo3 + stream stdout/stderr directly
-m MODEL	Select model (e.g. gpt-5.3-codex, o3)
--oss	Use local model provider (LM Studio / Ollama)
--search	Enable live web search
-i FILE	Attach image(s) to initial prompt
--cd DIR	Set working directory
--profile NAME	Use config profile from config.toml

Examples

# Fix a bug with full autonomy
codex-infinity --full-auto --auto-next-steps "fix the failing test in auth.test.ts"

# Refactor with idea generation
codex-infinity --auto-next-steps --auto-next-idea "refactor the API layer"

# Quick one-shot with yolo mode
codex-infinity --yolo "add error handling to all API endpoints"

# Use a specific model
codex-infinity -m gpt-5.3-codex --auto-next-steps "optimize database queries"

# Use local models
codex-infinity --oss -m llama3 "explain this codebase"

Features

• Autonomous operation -- --auto-next-steps keeps it working without intervention
• Idea generation -- --auto-next-idea brainstorms and implements improvements
• AnyLLM -- OpenAI, local models via LM Studio/Ollama, bring your own provider
• Local execution -- runs entirely on your machine
• Concise prompts -- stripped-down system prompts for faster, more focused responses
• Higher reliability -- increased retry limits for long-running autonomous sessions

Development

Build from source (Rust CLI)

cd codex-rs
cargo build --release -p codex-tui
./target/release/codex "your prompt here"

Build npm package
