## Summary

Shiro, a non-engineer who built a SaaS using AI, now relies on **Claude Code (Opus 5.5)** for new projects instead of OpenAI’s **Codex**. The shift came after **Opus 5.5** relaxed usage limits on the Pro plan, making it easier to handle development tasks without hitting caps. Shiro highlights Opus 5.5’s ability to infer intent better than **GPT-6 Astra**, reducing back-and-forth exchanges and delivering polished outputs from single prompts.

Shiro still uses **Codex** for maintaining existing projects but notes AI’s rapid evolution means tools may change quickly. Their key takeaway: the focus should be on clarifying project goals rather than picking the ‘best’ AI. A prior article details how their SaaS secured **¥34,800/month** in contracts within its first month, despite early failures with **Codex**.

## Key points

- Claude Code (Opus 5.5) now feels more reliable for Shiro due to looser Pro plan limits
- Opus 5.5 outperforms GPT-6 Astra for Shiro’s workflow by inferring intent more accurately
- Shiro still uses Codex for legacy projects but prefers Opus 5.5 for new builds

## Why it matters

For non-engineers, Opus 5.5’s improved intent-understanding and relaxed limits could lower the barrier to building software with AI, though oversight remains critical.
