Should teams pick only one runtime?
Not necessarily. onesagent is strongest when teams want to compare and route across multiple runtimes instead of committing to one lane forever.
Compare Codex and Claude Code across quota posture, cost, runtime, model balance, and the tasks that benefit from managing both inside onesagent.
Choose Codex when quota behavior and coding-lane tradeoffs dominate. Choose Claude Code when research-oriented model balance is the main concern. Manage both in onesagent when you need explicit fallback and task-based routing.

Platform-level comparisons answer quota, stability, and buyer-intent questions that individual model pages cannot fully resolve.
