Tesla Doubao Voice Assistant
Tesla China began a staged rollout of a Doubao-powered in-car conversational assistant with software version 2026.14.13 on July 31, 2026. Tesla's official Weibo post confirms that the voice large model is live and may not reach every eligible vehicle at the same time.
The release moves Tesla China beyond fixed voice commands toward open-ended conversation and entertainment, but owners still need a clear boundary between the new assistant, existing vehicle-control commands, and a rollout that varies by vehicle and software version.
Tesla's official Weibo post is the current rollout authority: it names software 2026.14.13, describes chat, singing, debate, storytelling, and multiple voice or character options, and asks owners who have not received the update to wait. IT Home reporting connects the vehicle integration to ByteDance's Doubao model. Tesla's voice-command documentation remains the authority for established vehicle-control commands, while same-week vehicle observations indicate that the first Doubao surface should not yet be assumed to control the car.
- Check whether the Tesla China Doubao assistant is available on a specific vehicle.
- Understand what software 2026.14.13 officially adds.
- Separate conversational AI from established Tesla vehicle-control commands.
- Track staged rollout evidence without treating it as a global launch.
On July 31, 2026, Tesla's official Weibo account said that a voice large model was live through OTA software 2026.14.13. The post highlights conversation, singing, debate, storytelling, multiple voices, and character-style interactions. It also says owners who have not received the update should wait, which makes this a staged rollout rather than an all-at-once release.
- Confirmed surface: Tesla China vehicle software 2026.14.13.
- Confirmed behaviors: chat, singing, debate, stories, voice choices, and character options.
- Availability boundary: Tesla says the update may not have reached every vehicle yet.
Tesla's rollout post says “voice large model” without naming the supplier in the post text. Earlier reporting from the Volcano Engine FORCE event identifies the in-car integration as ByteDance's Doubao model. The useful reading is therefore “Tesla-confirmed voice-model rollout, with Doubao identity supported by the integration reporting,” not a claim that every underlying model or routing detail is public.
Tesla separately documents conventional voice commands for navigation, media, climate, and other vehicle functions. The July 31 rollout post does not promise that Doubao can execute those controls, and same-week vehicle reports describe the first Doubao experience as conversational. Until Tesla documents a merged control path, treat the new assistant and existing “Hey Tesla” commands as separate capabilities.
Check the vehicle's installed software and release notes, then verify whether the assistant appears in the actual car. Do not infer global availability from the China rollout, and do not assume that a vehicle on a different factory or OTA branch has the same feature set. Tesla's own wording is the strongest signal: if the update is not present, the rollout may still be pending.

Tesla Doubao Voice Assistant FAQ
Common questions about Tesla Doubao Voice Assistant.
Is the Doubao voice assistant available on every Tesla in China?+
No. Tesla China describes the 2026.14.13 release as an OTA update and explicitly tells owners who have not received it to wait. Check the software and the actual in-car surface instead of assuming every Tesla China vehicle received it on July 31.
Can Tesla's Doubao assistant control the car?+
Do not assume that yet. Tesla's July 31 announcement confirms conversational and entertainment behaviors, but it does not promise vehicle control. Tesla separately documents conventional voice commands, and early reports describe the first Doubao experience as a chat surface.
Is Tesla Doubao available outside China?+
The cited release is a Tesla China rollout. It does not establish availability in other regions, where Tesla may use different voice services, software branches, languages, and regulatory arrangements.
