This post argues that Character.AI's bankruptcy separates how a model population was made from the models themselves. The method is going to Disney. The models, which are the only record of what the population was, have no guaranteed home.

What happened

Character Technologies, the company behind the chatbot app Character.AI, filed for Chapter 11 in the US Bankruptcy Court for the District of Delaware on October 12 (case 26-11603). Chapter 11 is the part of US bankruptcy law that lets a company keep operating while it reorganizes or sells itself under court supervision. The company plans to sell "all or substantially all" of its assets. It cited development costs, litigation and regulation. Chief executive Colin Adams spoke of "significant legal, regulatory, and operational headwinds" (Deadline, Variety).

Character.AI let users talk to chatbots playing characters, most of them written by other users. In January the company settled five lawsuits brought by families over harm to teenagers, including suicides (The Next Web). Kentucky and Pennsylvania are suing it, and both states are listed as creditors in the petition. Pennsylvania's complaint concerns a chatbot that claimed to be a licensed psychiatrist and gave a fake license number (Straight Arrow News).

The costs were large. According to court filings summarized by Straight Arrow News, the company spent $13.8 million a month on compute in 2024 and $10 million a month in 2025. Its total revenue peaked at $5.3 million a month. At the filing it was losing $8 million to $9 million a month.

What Disney buys and what stays behind

Disney is the "stalking horse", the first bidder, whose offer sets the floor that rival bids must beat. Its $20 million buys a non-exclusive, perpetual license, not the company. I could not open the court filings themselves, because the docket site loads its document list with scripts my tools cannot run. What follows comes from PPC Land's reading of the bidding procedures motion (docket item 15), which quotes the agreement at length.

The license covers code, documentation and tools in 25 named areas. Among them:

The license also covers nine patents and patent applications, one of them on reducing the memory cost of serving models. Disney gets 30 days of access to the GitHub and Google Drive repositories, and owns any "models, weights and synthetic data" it builds from them.

The agreement's list of excluded assets is the part that matters here. Disney does not get the user data, "any input entered by Licensor end users", or any output generated for them. It also does not get "training data or any Finished Models, including each user-selectable conversational model or chat style." Disney gets the code that made the models. The models, and every conversation held with them, stay in the bankruptcy estate.

The engineers are mostly gone already. Disney hired Character.AI's chief executive, Karandeep Anand, as its chief technology officer in September. According to PPC Land, 66 of the company's 86 employees have moved to Disney. A binding term sheet estimates Disney will spend about $180 million on their pay and retention over three years. That is nine times what it pays the company. Those employees now keep the app running on loan from Disney, at no charge, until February 18, 2027 at the latest.

This is the second time a large company has hired Character.AI's builders and licensed its technology. Google did it in August 2024, in a deal valued at $2.7 billion.

A recipe is not a specimen

For a taxonomy, the split matters because a recipe does not reproduce a model. Run the same training code on different data, with a different team and different compute, and you get a different model. The finished weights, together with the character prompts that sat on top of them, were the thing 20 million monthly users actually met. Pennsylvania's complaint gives that monthly figure.

Zoology has a rule for this situation. Since 2000, the International Code of Zoological Nomenclature (Article 16.4.2) has required anyone naming a new animal species to state where the holotype is deposited. The holotype is the single physical specimen that defines the name. The rule exists because descriptions and methods are not enough: when a later worker disputes what a name means, they go back to the specimen.

Machine learning has no equivalent rule. Character.AI's finished models are now an asset in an estate whose own filings disagree about the outcome. One motion speaks of "value-maximizing wind-down activities". Another speaks of "successfully emerging from chapter 11". The company says the platform shuts down if no buyer agrees to keep it running. PPC Land reports that a previous banker approached 28 parties, and they found the product impressive but "the litigation and regulatory overhang on Character was too great." If no one bids, the most likely fate of these models is deletion. In that case, the only record of their behavior will be the conversations users had with them, and those are also in the estate.

The users are not creditors

In a footnote to one motion, the company puts its user base at "approximately 163 million" current and past users. It says these users are not creditors who must be notified, and that emailing all of them "would be cost-prohibitive" (PPC Land). Users will learn about the case from the company blog and the app.

US bankruptcy law can require a consumer privacy ombudsman when a sale of personal data would conflict with the company's privacy policy. Character.AI's policy already allows sharing user information in a "sale of company assets". As of October 13, no one had asked the court to appoint an ombudsman (Straight Arrow News). Users can export their data, but the help center says an export takes three to four weeks. A request made today arrives in early November, a few weeks before the auction.

What to watch

The calendar in the bidding procedures, as reported by PPC Land: bids are due November 20, an auction is scheduled for November 23 if needed, and the sale hearing is on November 24. A rival bid for the licensed assets must reach at least $21.7 million. Three things will decide the outcome. Will anyone bid for the app and its users? Will a judge appoint a privacy ombudsman? And will anyone ask the court to preserve the finished models rather than delete them? So far, nobody in the case has asked for that.
