Ox Alpha vs GPT-5
GPT-5 is a known, moderated, paid frontier model. Ox Alpha is a stealth model of unknown origin that's free during preview. Here's how they actually differ where it matters.
- Context window
- Reasoning
- Price
- When to pick which
Context window
Ox Alpha exposes a full 1,048,576-token context. That's its headline advantage for whole-codebase and long-document work.
- Ox Alpha: 1M tokens
- GPT-5: large, but check current limits
- Winner for raw context: Ox Alpha
Reasoning
Both are reasoning models. Ox Alpha makes reasoning mandatory with low/high/max effort levels and streams a visible chain of thought you can inspect.
Price
Ox Alpha is $0 during stealth; GPT-5 is paid per token. The catch: stealth pricing is temporary and the pool rate-limits, so it's not a production guarantee.
When to pick which
Reach for Ox Alpha when you want a huge context window and free experimentation. Reach for GPT-5 when you need a stable SLA, moderation, and predictable availability.
