Mystery model "Frantic Ferret" surfaces in OpenCode's catalog, gone 3 days later with developer still "Unknown"

A catalog reference the post itself calls "not a release"

A reference to "frantic-ferret," a model whose developer is not disclosed, appeared in the model catalog that the AI coding tool OpenCode publishes. @aitrackerbot, an X account that automatically tracks the appearance of new models, reported it on Nov. 8 (3:58:10 a.m. Nov. 9 Japan time). The post said it had found the reference in the "OpenCode Zen" catalog, adding that availability and specifications were unconfirmed and that a code reference does not mean a release.

Missing from the official catalog and documentation 3 days later

The official OpenCode Zen catalog that ORIENS retrieved at 6:45 a.m. on Nov. 12 listed 85 models, none with "ferret" in the name. A separate model list that OpenCode points to also showed 85 models, and frantic-ferret was not among them.

OpenCode's model documentation does not include Frantic Ferret in any of its lists: models and pricing, free models, exceptions to data handling, or deprecated models. Because it is not listed as a deprecated model either, the official documentation does not show whether it was ever formally offered.

OpenCode's public documentation does not state the pricing, whether the model is free, the period or regions of availability, or the terms for storing input data or using it for training. Specifications listed in the catalog at the time of detection, such as the context window, cannot be confirmed in official records, so this article does not cover them.

About 9.9 billion tokens of use in one day

OpenCode's public usage statistics by model, however, still have a page for frantic-ferret. In the daily records, Nov. 8 is the only day with any usage: about 9.885 billion tokens (units of text) were used by 347 users across 2,636 sessions. The cost field shows $0, and all usage for Nov. 9 is zero. The data was last updated on Nov. 8 (6:26 a.m. Nov. 9 Japan time).

That one day of usage put the model 42nd by usage over the past week. Just above it at 41st was "hy4-preview" from China's Tencent with about 13.37 billion tokens, and just below it at 43rd was "step-5-preview" from China's StepFun with about 7.75 billion tokens.

Developer listed as "Unknown," no word on its identity

OpenCode's statistics list frantic-ferret's developer as "Unknown." The fields for context window, maximum output, pricing and accepted data types are also empty.

Neither OpenCode nor any AI model developer has announced what Frantic Ferret is. In November, OpenCode also offered free models whose developers were not disclosed, such as "Pulse Alpha" and "Iceman." Iceman Free is still listed in the documentation as a free model with an undisclosed developer.
