Stealth Alpha Models: Timeline, Codenames and Reveals
Stealth Alpha Models are anonymous model listings that may later receive a public name. This page records the codenames and later mappings already documented on this site, while separating historical context from vendor confirmation. It does not identify Space Bunny Alpha by inference.

How to read this timeline
A later public mapping is not automatically an official technical confirmation. The table preserves the current site record; it does not fill missing dates or upgrade tracker reports into proof of ownership.
What this Stealth Alpha Models timeline tracks
This page answers a narrow question: which anonymous Alpha codenames have a later public mapping in the current site record? It is not a prediction engine and it is not an ownership database. The available local record contains six mapping rows covering seven codenames because Hunter Alpha and Healer Alpha share one row.
No exact first-seen or reveal date is supplied for every mapping here. That omission is deliberate: the existing record names the mapping but does not provide a row-level source and date for each item.
Known Stealth Alpha codenames and later public mappings
| Codename | Later public mapping in the site record | Date | Evidence boundary |
|---|---|---|---|
| Pony Alpha | Z.ai GLM-5 | Not established here | Historical record Mapping recorded by public stealth-model trackers. |
| Hunter Alpha / Healer Alpha | Xiaomi MiMo | Not established here | Historical record Two codenames are grouped in one existing record row. |
| Elephant Alpha | Ant Lingxi | Not established here | Historical record Mapping recorded in the current site history. |
| Owl Alpha | Meituan LongCat-2.0 | Not established here | Historical record Mapping recorded in the current site history. |
| Ox Alpha | Z.ai GLM-5.3-Flash | About six days before reveal | Historical record The site separately records the approximate free-preview gap. |
| Union Alpha | Unbiased Pareto | Not established here | Historical record The site records that its free stealth period ended. |
The table is a historical mapping record, not a claim that every row has identical evidence. For a future update, add a source and a date to the individual row before presenting either as confirmed.
Three recorded reveals: what is known and unknown
The historical record is most useful when each reveal is treated as a limited case study rather than as a template for guessing. The entries below are the three clearest examples currently available in the site record. “Known” means what the record says about the later mapping; “unknown” means the source, date or technical relationship is not established by the material collected here.
Pony Alpha: recorded as Z.ai GLM-5
Known: Pony Alpha appears in the historical mapping as Z.ai GLM-5. That makes it an example of a codename later associated with a named model and vendor. It belongs in the timeline because the mapping is part of the public tracker history used by this site.
Unknown: This page does not establish the exact first-seen date, reveal date, testing route or technical evidence that connected the codename to GLM-5. It also does not use the Pony Alpha mapping to identify another anonymous model. A historical association is useful context, but it is not a transferable fingerprint.
Ox Alpha: a roughly six-day free preview before the reveal
Known: The site record says Ox Alpha was free for roughly six days before Z.ai revealed it as GLM-5.3-Flash. This is the most concrete timing detail in the current record, so it is useful for understanding the practical lifecycle of a stealth listing: a free testing window can end when a vendor attaches a public name to the model.
Unknown: “Roughly six days” is not a general countdown for every Stealth Alpha model. It does not predict when Space Bunny Alpha will be claimed, and it does not show that Space Bunny Alpha shares Ox Alpha’s architecture, provider or product lineage. The timeline records an observed historical interval, not a service-level promise.
Union Alpha: a mapping with a changed product status
Known: Union Alpha is recorded as Unbiased Pareto, and its free stealth period has ended. This case shows why a reveal can matter to users even when the identity question is not their main concern: the public name, pricing, route and availability may no longer match the anonymous preview.
Unknown: The current local record does not provide a row-level reveal date, original listing details or a reproducible technical comparison. It therefore cannot tell us how much of the anonymous preview carried into the named product. Treat the mapping as a recorded public association, not as a complete model card.
These three examples also explain why the Stealth Alpha Models page should preserve uncertainty. A reveal can establish a public name without answering every technical question, and a technical resemblance can appear before any vendor confirms ownership. Keeping those claims separate makes the timeline more useful for researchers, developers and readers deciding whether a free preview is safe to depend on.
What the historical record supports
The record supports a cautious base-rate observation: anonymous Alpha releases can later be associated publicly with a named vendor or model. That makes a future reveal plausible, but it does not say when a reveal will happen or which vendor is involved.
It also supports a practical product warning. If a free stealth preview is useful to your workflow, keep a fallback and avoid treating the codename as a permanent product contract. A historical reveal may change the price, route, name or availability.
What this history does not prove
- It does not prove that Space Bunny Alpha is made by any particular company.
- It does not turn a tokenizer-family match into proof of a model checkpoint or owner.
- It does not establish exact release or reveal dates where the current record has none.
- It does not mean every public mapping has the same level of official confirmation.
Space Bunny Alpha status
Unclaimed in the current site record
Space Bunny Alpha appeared on 23 September 2026 and was recorded as unclaimed on 24 September 2026. The TokenRA provider is anonymous. Independent tokenizer-family evidence points toward MiniMax, but the stealthprint case study tested a same-codename model served through OpenCode Go, not directly through TokenRA. The case study says that tested model was not listed on OpenRouter, so the result is not a direct ownership confirmation for this listing.
Use the identity evidence review for the full caveat, and the free limits guide for the practical consequences of a possible claim.
How to evaluate a future reveal
- Look for a direct vendor statement. A named claim is stronger than an informal guess or the model's own answer.
- Check the exact model and gateway. Evidence from a same-codename model on another route may describe a sibling or a different listing.
- Separate family evidence from product evidence. A tokenizer match can narrow a family; it cannot by itself prove ownership or quality.
- Record the source and date. A timeline is more useful when each row can be audited instead of relying on an undated summary.
Stealth Alpha Models FAQ
Which Stealth Alpha models are recorded on this timeline?
The current site record covers seven codenames in six mapping rows: Pony Alpha, Hunter Alpha, Healer Alpha, Elephant Alpha, Owl Alpha, Ox Alpha and Union Alpha.
Does this history prove who made Space Bunny Alpha?
No. The mappings are context and a base rate, not proof of Space Bunny Alpha's identity. Space Bunny Alpha was unclaimed in the site's last review record, and tokenizer-family evidence does not establish ownership.
Were all previous mappings officially confirmed?
This page preserves the site's historical mapping record and does not claim that every row has the same source status. The current local record does not include a source and reveal date for every row, so treat them as recorded public mappings rather than uniformly official confirmations.
What would count as a real reveal?
A direct vendor claim or reproducible, distinguishing evidence is stronger than a writing-style guess, a model self-report or a tokenizer-family match alone.
