Teffa Alpha is an anonymous model tracked by the Fengshenbang Mystery Model Radar. The page logs public sightings, evidence, predictions, and behavioral fingerprints without presenting speculation as fact. Explore four clickable Arena webpage previews. The tester retracted the Google attribution and reports a dirty-token lead toward Qwen; independent reproduction remains pending.

Task: Origami and starfield themed webpage (prompt pending)
The public Arena result is titled “折纸星域 · 纸折的世界，星下有人家”. Only the observable page title and URL are recorded for now; the original prompt has not been supplied.

Task: Model self-introduction webpage (prompt pending)
The public Arena result calls itself “Claude” in the title. That is output behavior, not standalone proof that Anthropic supplied the underlying model; the original prompt is still pending.
Identity signal: The output self-identifies as Claude, conflicting with the dirty-token lead toward Qwen

Frequently asked questions
What is Teffa Alpha?
Teffa Alpha is an anonymous model name under early community tracking. Four public Arena results are archived, while product positioning, API access, and provider attribution remain officially unconfirmed.
Who made Teffa Alpha?
The tester now rules out Google and considers Qwen the most likely family based on a dirty-token match. A fourth webpage self-identifies as Claude, but model self-identification does not prove the underlying provider. Without published raw responses, the triggering token, and a reproducible probe, Qwen remains a strong lead rather than an official attribution.
How can I use Teffa Alpha? Is there an API?
As of this snapshot, no verified official access route or public API has been found. The four Arena results are behavioral observations, not model access endpoints.
Are there reliable Teffa Alpha benchmarks?
No independently reproducible benchmark is ready for publication. The four webpages are user-submitted behavioral samples and do not replace standardized prompts, raw responses, environment records, and repeated trials.
