Ox Alpha review: what a stealth model gets right

We tested Ox Alpha directly against the live API. Here's what held up and what to watch for.

Key takeaways
  • What's good
  • What's rough
  • Verdict

What's good

Massive context, solid reasoning you can inspect, reliable tool calling, real streaming, and a $0 price during preview.

What's rough

Strict JSON schema isn't honored, the free pool rate-limits, and there's no provenance or SLA — it's a preview.

Verdict

A genuinely capable model for experimentation and large-context work. Don't bet production uptime on a stealth endpoint yet.
