stealth/ox-alpha on 2026-08-28; the free access paths documented here may no longer resolve. See what the removal means.How to Use Ox Alpha Free Right Now
Ox Alpha is currently free on Command Code while the preview lasts. OpenCode exposes a separate free preview alias, while Z.ai's named GLM-5.3-Flash has a paid API rate card; do not assume the preview price transfers to Z.ai directly.
1. OpenCode — verify the live free alias
Install OpenCode, connect a provider, and run /models. OpenCode's live Zen model endpoint currently exposes x-preview-f-free. Its public endpoint does not label that ID “Ox Alpha,” so treat the mapping as unconfirmed and verify the live picker before using it.
2. Command Code — free model, paid harness
Command Code's official model page lists stealth/ox-alpha at $0 for input, output, and cache reads while the stealth preview lasts. The same page says the model is available on Go and higher, so the model request is free but the Command Code harness is not necessarily free.
Do not confuse free tokens with free risk
Use synthetic or public code first. Confirm the active provider's data policy, rate limits, and retention terms before sending secrets, customer data, or proprietary source code.
A reliable test sequence
- Try the OpenCode alias only after confirming it appears in the current picker.
- Use Command Code's current model page to confirm the preview price and plan requirement.
- Record interruptions, retries, latency, tool-call errors, and total tokens—not just whether the final answer looked good.
- Keep a named Z.ai fallback configured because previews can be renamed, rate-limited, or removed.
