Lost in Translation

A Luxury Maison takes decades to settle how it speaks. Google is testing a tool, spotted in early October, that translates ads on its search engine into ten languages and variants, French among them. To tell it how to speak, the Maison has only a field of written instructions, for which Google gives two examples: keeping a brand name intact, adopting a formal tone, according to the trade site Slator on October 12 and Google Ads help.

Edition #26 · Lost in Translation

Agents enter brands through the tasks that speak in their name: translating a campaign, writing a product page, answering a client. Brand guidelines set the rule; they rarely state the exception, the register owed to a client who has been loyal for thirty years, the word one avoids in Tokyo. That is what gets lost along the way: Lost in Translation. Edition 10 approached it through the Pact of Legibility, what we encode for agents and what we leave unsaid; Edition 19, through the compiled brand, doctrine handed over to the machine. What was missing was a first record of what gets lost: Epoch AI published one on October 8, outside Luxury.

"Lost in Translation" borrows its title from Sofia Coppola's film (2003). Bill Murray shoots a whisky commercial in Tokyo; the director speaks to him at length in Japanese, the interpreter sums it up in one sentence, and the actor asks whether that is really all he said. Between a brand and its agents, the same thing gets lost.

"What is written nowhere does not make it into an agent's instructions."

Welcome to LUXE ÆTERNAI, my weekly decoding of what AI agents change, or don't, for Luxury Maisons. I am Michaël Tsakiris. I help leaders and their teams choose what they entrust to AI, put it in place, and I train them. Enjoy!

TL;DR (Too Long; Didn't Read)

The essentials of the week

The thesis. Agents enter brands through the tasks that speak in their name: translating, describing, answering. What the guidelines leave unsaid does not make it into their instructions: that is the Lost in Translation.

The paradox. The more fluent a machine translation, the less visible what it has lost; Luxury, which speaks through implication, is the most exposed.

What's moving. The RealReal hands search to an agent, at the risk of depriving the buyer of the find; a Bulgari job posting mentions agents for its client advisors.

The three that count, outside Luxury. London consults on agents, Workday sets them action by action, Washington and more than 400 researchers call for AI incidents to be reported.

Decoded. Luca de Meo wants a single AI backbone for Kering's Maisons; Epoch AI shows that models put to work as agents succeed at code and calculations, and miss implicit conventions.

The story. The Meta and Sierra protocol, JPMorgan Chase and American Express set what a client's agent can read and do, without the Maisons.

Beta Luxury. A brand ambassador's voice rendered by AI in every language: the technology is ready, consent is not yet.

In my reading list. Who owns the client in the age of agents, ads made by AI, the value AI actually delivers, and Howard Becker on conventions.

Coming next. LVMH's Journées Particulières from the 16th to the 18th, Hermès, Prada, L'Oréal and Kering on the 22nd.

The paradox of the week

The more fluent a translation, the less you see what it has lost.

Luxury judges on detail. Machine translation is improving mainly in fluency, and fluency hides the missed detail.

On October 13, the BBC interviewed translators and researchers. François Yvon, research director at the CNRS, observes that a good system renders the French idiom "il pleut des cordes" (it's pouring ropes) into English, but wonders whether it will manage in Indonesian. Carol Bereuter, a medical translator, describes errors that are harder to spot because the text "sounds perfectly legitimate."

In Dublin, on October 10, Trish Van Bolderen, who chairs the executive committee of the Irish translators' association, summed up the effect before a trade union: fluency "can trick you into buying what's being presented," according to the Dublin InQuirer.

"Fluency is the best disguise for a mistranslation."

The anthropologist Edward T. Hall distinguished in 1976, in Beyond Culture, so-called high-context cultures, where meaning lies in what surrounds the words, from those where everything goes through the words. Luxury speaks in high context: the way to address a regular client formally, the name of a house canvas one does not translate. The psychologists Rolf Reber and Norbert Schwarz measured the effect of reading fluency in 1999: a sentence that is easier to read is more often judged true. So a brand has its translated texts reviewed by someone who knows it in the target language, and asks that person what is missing, not what is wrong.

What's moving

The RealReal hands the search for pieces to an agent, a Bulgari job posting mentions agents.

The RealReal hands the search for pieces to an agent. On October 8, the Luxury resale platform opened Ask TRR to its 45 million members, according to the press release distributed by Google Cloud. The agent searches in plain language across more than one million one-of-a-kind pieces and suggests a selection; the release does not credit it with any purchase. The platform also plans recommendations on its product pages, according to Luxury Daily on October 12, which relays the press release without any figures from the trial phase.

The next step is easy to guess: agents mandated by their clients that will search, find and buy on their behalf. A platform would then need fewer pages for humans than entry points for machines: direct access to its catalog, the MCP protocol (Model Context Protocol), which plugs an agent into a tool, or A2A (Agent2Agent), which lets two agents talk to each other.

Yet I do not believe in resale without humans. The agent will serve the buyer who already knows what they want, the reference, the size, the price; the treasure hunter will keep browsing. The one who delegates no longer experiences the find, the piece sought for years and unearthed oneself, and the brand whose piece is being resold loses a moment when its name mattered to them.

A Bulgari job posting in Shanghai mentions agents for client advisors. A job posting published on October 10 in Shanghai, for a data and AI role, lists among its duties supporting "Agentic AI initiatives" with client advisors and client relations teams. Of 696 LVMH job postings published from October 6 to 12, which I collected on the 12th from LVMH's recruitment portal, five mention agents: one at Bulgari, four at Sephora, a retailer, including an internship to automate task workflows. Like the postings collected in Edition 20, they show a team getting trained; none describes an agent already in service.

The three that count

Outside Luxury, the agentic week in three facts.

1. London consults on agents until November 20. On October 8, the British data regulator (ICO) launched a six-week call for evidence, open also to companies that deploy agents (ICO); Richard Nevinson, its director of technology regulation, warns that "the fact AI agents act with autonomy is not an excuse for poor compliance," according to the ICO, as reported by UKAuthority. Why it matters: a brand whose agent answers British clients is concerned, and can respond before the deadline.

2. Workday lets the client set its agents action by action. On October 13, the software maker announced agents that work in the background on recruiting, then payroll and accounting (SiliconANGLE, CIO); the client sets three levels, from automatic action to human decision, with review in between, according to CFO Dive. Only recruiting is open, to early customers; payroll and accounting will follow in early 2027. Why it matters: if your group runs its payroll in this kind of tool, the agent will arrive through the vendor's update, and the three-level setting has to be decided before switching it on.

3. Reporting AI incidents becomes a shared demand. On October 9, the White House let it be known, with no published text, that AI companies must "immediately disclose" incidents involving their models, according to PYMNTS, citing Axios. On the 13th, more than 400 researchers called for an international body that records every loss of control over a model (BetaKit); in London, OpenAI and Anthropic backed binding rules, Google DeepMind and Meta declined to back new legislation (Wired). In Europe, the AI Act already requires providers of the largest models to report their serious incidents (Article 55). Why it matters: a brand that buys an agent can require its vendor, by contract, to report any incident within a set time frame.

A single AI backbone for all of Kering's Maisons?

In an interview published by WWD on October 7, Luca de Meo, Kering's CEO, defines the creativity of a Luxury brand as a chain: the studio, merchandising, purchasing, suppliers, in-store presentation. "One of my priorities in the next six months is to reengineer that," he says, aiming to open the studio up to the rest of the group.

He mentions AI only once, about the services the group wants to pool, outside the studio: "Imagine that I have to build an AI backbone for the houses. Do you want to do it 10 times, or do it once?" according to WWD.

On October 9, Saint Laurent announced the departure of Anthony Vaccarello (Kering press release, Il Sole 24 Ore). Any creative leadership that leaves takes with it part of what was never written down.

What can a shared backbone carry? Epoch AI, a nonprofit research institute that measures the progress of AI from data, offers a clue. On October 8, it evaluated models not on standardized tests, but on its own work, with its own rules. An exam tells you whether a model can do something; this test tells you whether it works the way the organization that employs it does.

Kelly Hong and Greg Burnham gave six models eleven of the institute's tasks: graphics, short analysis pieces, data tools, investigations into AI data centers, study design. Each model worked alone, as an agent, with Epoch's style guide and templates; a single human grader, one attempt per model.

What succeeds. Code and calculations are, in the most advanced models, "consistently accurate," according to Epoch.

What fails. What the authors call implicit conventions. The models pick topics too specialized for Epoch's audience. They pile on information where the institute insists on saying little, and clearly. They copy a visual code without understanding the rule behind it. The authors sum it up: the models "consistently missed implicit conventions that humans would pick up," according to their October 8 publication.

"Today, an agent executes the instruction; it does not guess the convention."

The failures Epoch found, choosing the angle of a text for its audience, saying little rather than everything, applying a visual code while knowing why it exists, threaten the tasks named at the start of this edition: translating, describing, answering. Gucci and Saint Laurent do not do them the same way, and that difference is precisely what an agent loses along the way.

What the measure does not prove. Epoch measured its own research institute, whose audience and rules are not those of a Luxury brand. The authors say so: small sample, subjective grading, scores too noisy to be taken at face value. I found no follow-up that discusses this measure with an outside view: the evidence rests on a single source.

And the line is moving: publishing an article on Substack, a task failed earlier this year, now succeeds, according to the same Epoch publication.

In Luxe Agentique, my upcoming book, I start from the five invariants of Luxury: Excellence, Exception, Experience, Emotion, Elevation. As I wrote in Edition 21, the agent can carry on its own the Excellence of execution of an office task, a calculation or a piece of code, not that of the craft gesture: that is what Epoch sees succeed. The other four require a human hand, and what Epoch sees fail belongs to them: the angle chosen for an audience, restraint, a visual code understood.

What I take from this.Edition 9 argued that Kering's pooling stops at creation. Luca de Meo confirms it and puts a date on it: the services are built once for all the Maisons, the studio stays with each, and he gives himself six months to reengineer the creative chain. That is the right order in which to draw the red line before plugging in a single agent. An agentic doctrine serves exactly that purpose: the agent receives what can be verified, the names one does not translate, formal address, the banned words; the client advisor, the reviewer in each market and the studio keep the tone, the register and the final word, what an agent would lose along the way.

The story of the week

What a brand allows a client's agent to do on its premises.

On October 6, Meta and Sierra, a maker of customer service agents, announced the Personal Agent Protocol, a common rule for the personal agent that shows up at a company on behalf of its client (Sierra, PYMNTS). The client chooses what the agent can read or do; the brand sets what it opens and what the agent is allowed to do there. On the 9th, a draft followed, with 35 new design partners, including Nordstrom, Visa, Mastercard and Adyen (Sierra, October 9, PYMNTS). It is only a draft, and no Maison appears among the 42 partners, the seven launch partners included.

On October 13, JPMorgan Chase drew its line. The bank blocks personal agents such as Meta's Muse, or Spear Street Technology's Instinct, which log in with the client's credentials to pay or transfer money; it allows them read access only (CNBC). "There's a liability transfer," Jamie Dimon warns, addressing the client who delegates (Banking Dive).

The same day, American Express published a framework in which the client records an intent before the purchase (merchant, budget, preferences); the card can decline a purchase that departs from it. Amex counts thousands of agent purchases every week, with no denominator, according to Digital Transactions.

"The Maison sets what it opens to the agent, what the agent can do there, and who answers if it gets it wrong."

Three players, one grid in three questions. At JPMorgan, according to Jamie Dimon, the client who delegates bears the risk; at Amex, the card blocks the deviation before the purchase; who answers if it lets it through, the release does not say. A client's mandate, like a brand's guidelines, protects only what is written.

What I take from this.In Edition 21, an agent bought a shirt despite a "don't buy," and no one could prove the mandate. Amex adds a piece: the intent, recorded before the purchase, which the card compares with the agent's request. Like the intent mandate in Google's AP2 protocol (Agent Payments Protocol), designed for when the client is not present, it proves a scope, not yet the client's will on that particular purchase, and nothing says a brand will see it. It remains for each brand to set what it opens to a client's agent for reading, and what it denies it for writing.

Beta Luxury

A brand ambassador's voice in every language: the technology is ready, consent is not yet.

A brand subtitles its ambassador's film, or dubs it with other voices; synthetic voice vendors promise to keep the ambassador's timbre in every language. I found no Maison that has announced it.

TED already does it. Its head of localization, Cissy Yun, described on October 7 in MultiLingual a start with eight talks in five languages, with each speaker's consent. She details one misfire: a first Mandarin version with a foreign accent, since corrected by new models.

The right ground: ambassador films and campaigns, with the ambassador's consent; in the workshop, the artisan keeps their own voice, subtitled. In May, in Edition 11, I wrote that a brand's sonic identity would become codifiable like a color. TED's experience tempers that forecast: timbre is quickly tuned, the feel of a language still needs a human ear.

"An ambassador contract that names only one language is already out of date."

First trap, consent. On October 13, according to the Asahi Shimbun, the Japanese actors' union adopted guidelines, to be published shortly: prior consent at every stage and, for multilingual dubbing that keeps the actor's timbre, additional consent and pay for each language.

Second trap, the origin of the voice: on October 9, Royal Mail acknowledged that the voice-over of its 2025 Christmas ad came from an AI; the daughter of a narrator who died in 2014 says she hears her father in it, which the brand denies, on the word of its suppliers, according to The Independent. Since August, the EU AI Act requires disclosure of a synthetic voice that imitates a real person (Article 50).

By next year's holiday campaigns, I expect a Maison, or its fragrance licensee, to have its ambassador speak several languages through a synthetic voice.

The agentic Luxury calendar, October 16 to 22.

  1. Friday 16 to Sunday 18.

    LVMH's Journées Particulières: the workshops open to the public, including Louis Vuitton's in Asnières (LVMH).

  2. Thursday 22.

    Third-quarter revenue for Hermès (8 a.m.), nine-month sales for Prada (1 p.m.), revenue for L'Oréal (6 p.m.) and Kering (after market close).

The philosopher Friedrich Schleiermacher set out in June 1813, before the Berlin Academy, the choice every translator faces: bring the reader to the author, or the author to the reader. An agent always chooses the second: it brings the brand closer to the most common language. I would take a third way: train the agent in the Maison, by writing down for it what can be written, and entrust what gets lost along the way to those who carry it. Luxe oblige !

Set aside, for lack of an agent or of a link with this week's thesis: the Moët Hennessy sensor that spots a defect in the wine early, where a human decides; the Business of Fashion and Klaviyo round table on loyalty, with no agent; the 722 mathematics manuscripts published by OpenAI, neither Luxury nor agent.
