ByteDance plans the release of a Muse-like AI assistant in the coming weeks, Bloomberg News reported on 11 November, citing people familiar with the matter. Co-founder Zhang Yiming told the company’s AI team about the plan at a recent all-hands meeting, the people said, and sees ByteDance able to compete with Anthropic and OpenAI at the cutting edge, though he cautioned it would take until at least 2029 or 2030.
Doubao, the ByteDance AI assistant that Sina Tech reported Spell is being folded into, rests on a large model base. Volcano Engine president Tan Dai said on 23 June that Doubao’s large models handled more than 180 trillion tokens a day, up from more than 120 trillion he disclosed on 2 April. By our arithmetic, that is about 60 trillion more tokens a day, a rise of about 50%, between two disclosures 82 days apart.

A short explainer on AI agents, systems that move from answering to doing. It teaches the general idea and does not discuss ByteDance.
The key insight: As we read it, ByteDance is moving Doubao from answering to doing on a base that is already very large: more than 180 trillion tokens a day across its models in June, about 60 trillion a day more than in April by our arithmetic.
Bloomberg wrote that ByteDance plans the release “to augment its lead in AI video, a milestone event the company hopes will help close the gap with top US labs in as soon as three years”. At the all-hands meeting, Zhang “told researchers, engineers and supporting staff about the plan and set out key priorities”, according to the people, who asked not to be named because the meeting was private.
We could read only the first two paragraphs of Bloomberg’s report; those paragraphs do not name the product. A post by Wall St Engine on X at 10:31 UTC said the agent is “reportedly called Spell”, has been in internal testing since April and is expected to integrate with the existing Doubao assistant.
Average daily tokens processed by Doubao’s large models at each disclosure by Volcano Engine president Tan Dai: 120 billion at the initial scale in May 2024, more than 120 trillion on 2 April 2026 and more than 180 trillion on 23 June 2026, as reported by Kuai Keji and NBD. The rise of about 60 trillion a day, or about 50%, over 82 days is our arithmetic.ByteDance’s personal-agent path as reported: the Doubao phone assistant’s technical preview (December 2025) and consumer version (September 2026) and the Spell test from April, per Sina Tech; the 180 trillion daily tokens disclosed on 23 June, per NBD; Bloomberg’s report of a Muse-like assistant in the coming weeks; and Zhang Yiming’s horizon of at least 2029 or 2030, as people familiar described it to Bloomberg.
What Was Posted on X
ByteDance is preparing to launch a Muse-like AI agent, reportedly called Spell, in the coming weeks.
It’s been in internal testing since April and is expected to integrate with existing Doubao assistant.
Co-founder Zhang Yiming outlined the plan to ByteDance’s AI team.
Wall St Engine posted at 10:31 UTC on 11 November that ByteDance is preparing to launch a Muse-like AI agent, reportedly called Spell, in the coming weeks, in internal testing since April and expected to integrate with the Doubao assistant. The post cites no outlet; this piece draws the timing and Zhang Yiming’s remarks from Bloomberg’s report and the Spell name from Sina Tech’s 29 September report.
Where the Spell Name Comes From
The code name first surfaced in an exclusive by Sina Tech on 29 September, citing one person familiar with the matter. It reported that Doubao began internally testing an exploratory personal-assistant product in April, and that the project, code-named Spell, was “ไธป่ฆ็ฑ่ฑๅ ๆๆบๅฉๆๅข้ไธปๅฏผ”, in our translation led mainly by the Doubao phone-assistant team.
Sina Tech reported that after personal-assistant products such as Muse and Instinct gained attention overseas, Doubao was speeding up the release of its personal agent capabilities. The plan, it said, is to fold Spell more deeply into the Doubao product: “ๆฐไบงๅๅฐ็ฑSpell้กน็ฎไธ่ฑๅ ๅฏน่ฏๅข้ๅ ฑๅ่ด่ดฃ๏ผ้ขๆ่พๅฟซไผๅฏนๅคๆจๅบ”, in our translation the new product will be run jointly by the Spell project and the Doubao dialogue team and is expected to launch fairly soon. TechNode carried the Sina Tech report in English on 30 September.
The groundwork is Doubao’s phone assistant. Sina Tech says its technical preview first appeared in December 2025 and the consumer version was released in September 2026. Meta’s Muse, the product Bloomberg uses as the comparison, had been activated by more than 10 million people in its first six weeks, AMD chief executive Lisa Su said on 3 November, as we reported.
Our Number: The Token Base
Tan Dai’s two disclosures give the scale of Doubao’s model base. On 2 April, at a Volcano Engine roadshow stop in Wuhan, he said Doubao’s large models were averaging more than 120 trillion tokens a day, double the level of three months earlier, Kuai Keji reported. On 23 June, at Volcano Engine’s FORCE conference, he put the figure at more than 180 trillion, NBD reported, 1,500 times the initial scale of 120 billion a day in May 2024.
From 120 trillion to 180 trillion is about 60 trillion more tokens a day, or about 50%, in the 82 days between the two disclosures, by our arithmetic. Both figures are floors, since Tan said the totals exceeded each level. They cover all use of Doubao’s large models, not only the Doubao assistant app.
The Structural Read
As we read the reports, the race is over the personal-agent layer: Sina Tech tied the speed-up to the attention Muse and Instinct drew overseas, and Bloomberg compares ByteDance’s planned assistant to Muse itself.
As we read Zhang’s remarks as the people described them, the agent and the frontier run on different clocks: a release in the coming weeks, but at least 2029 or 2030 before ByteDance can compete with Anthropic and OpenAI at the cutting edge.
Bloomberg News, 11 November 2026
“He sees ByteDance able to compete with leading industry names like Anthropic PBC and OpenAI at the cutting edge, though he cautioned it would take until at least 2029 or 2030, the people said, asking not to be named as the meeting was private.”
Three Implications
FOR RIVAL ASSISTANTS Bloomberg reports ByteDance plans the release in the coming weeks, and compares it to Meta’s Muse, which AMD’s Lisa Su said more than 10 million people activated in its first six weeks.
FOR DOUBAO Sina Tech reported that the Spell project and the Doubao dialogue team will jointly run the new product, building on Doubao’s phone assistant.
FOR COMPUTE Volcano Engine’s figures put Doubao’s models above 180 trillion tokens a day in June, 1,500 times the May 2024 starting scale, by its own count.
The framework records: “The surface, not the model, governs autonomy.”
As we read it, a Muse-like assistant is that surface: Sina Tech reported Spell grew out of Doubao’s phone-assistant team and is being folded into the Doubao product. The framework predates the reports and does not discuss ByteDance.
What Is Not Established
Bloomberg’s report rests on people familiar with the matter, and Sina Tech’s on one person; in the material we read, ByteDance has not put a name, price or date on the product. The paragraphs of Bloomberg we could read do not say whether the Muse-like assistant is the Spell project. The most recent token figure in the reports we read is from June. Zhang’s 2029 or 2030 horizon is how the people described his remarks, not a published ByteDance target.

The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
ByteDance is preparing a Muse-like assistant for release in the coming weeks, Bloomberg reported. A Wall St Engine post said it is reportedly called Spell, the code name Sina Tech reported in September for a personal-agent project in internal testing since April and being folded into Doubao. Doubao’s large models grew from more than 120 trillion to more than 180 trillion tokens a day between April and June, about 50% in 82 days by our arithmetic.
A note on sourcing. We read the first two paragraphs of Bloomberg News’ report of 11 November 2026; the rest is behind a paywall. We read Sina Tech’s Chinese report of 29 September in full and quote it in the original, with our own translation; TechNode carried it in English. The token figures are Tan Dai’s disclosures as reported in Chinese by Kuai Keji on 2 April and NBD on 23 June; the translations are ours. The 60 trillion, 50% and 82-day figures are our arithmetic. We did not contact ByteDance.
