Grain vs Codex
Codex is a powerful code-generation model. Grain is an agent platform where Forge writes code, Scout researches markets, Beacon runs outreach, and Scribe ships your docs — all in parallel, all with approval controls.

WHY GRAIN WINS
Three reasons that matter.
01
Code is one of eleven jobs
Grain's Forge agent handles code, tests, and PRs. But while Forge ships your feature, Scout is researching your market, Beacon is warming your pipeline, and Shield is auditing your compliance.
02
Parallel, not serial
With Codex you get one AI working one task. With Grain Pro you get 25 agents running in parallel — your full fleet working simultaneously across every function.
03
Memory that survives the session
Codex knows what you told it today. Grain remembers what every agent learned last month — customer preferences, recurring issues, your writing style — and applies it automatically.
