Meituan's LongCat-2.0: The 1.6-Trillion-Parameter Model and What It Means for Local Services Ads
*Meituan has released LongCat-2.0, a 1.6 trillion parameter model trained entirely on domestic 50,000-GPU clusters. It's the first trillion-parameter model built without overseas chips. For brands advertising on Meituan's local services platform, this changes the game.*
LongCat-2.0: China's First Trillion-Level Domestic Model
On July 1, 2026, Meituan announced LongCat-2.0 — a 1.6 trillion parameter large language model that represents several industry firsts:
| Milestone | Detail |
|---|---|
| Parameters | 1.6 trillion (1.6T) |
| Training infrastructure | 50,000-GPU domestic computing cluster |
| Chip independence | No overseas chips used in any stage |
| Context window | 1 million+ tokens |
| Key optimization | Code agent capabilities |
| License | Open source |
The significance is hard to overstate. Previous trillion-parameter models from Chinese companies relied on NVIDIA GPUs and overseas infrastructure to varying degrees. LongCat-2.0 is the first to complete pre-training, fine-tuning, and inference entirely on domestic computing hardware. This is a geopolitical milestone as much as a technical one.
Why a Delivery Company Builds LLMs
Meituan is best known as China's dominant food delivery and local services platform, with 700 million+ annual transacting users and 9 million+ merchant partners. The question isn't "why would a delivery company build AI" — it's "why wouldn't it."
Consider what Meituan's platform does every day:
- Matches millions of user queries to millions of local businesses
- Ranks restaurants, hotels, services by relevance, quality, and user preference
- Generates personalized recommendations based on ordering history, location, and time
- Powers advertising auctions for merchant bidding on search and feed placements
- Processes billions of user reviews, photos, and merchant descriptions
Every single one of these functions is AI-native. Search ranking. Content understanding. Ad placement. Review analysis. The core infrastructure of Meituan's advertising business is AI — and LongCat-2.0 is its next-generation engine.
Implications for Local Services Advertising
Meituan's advertising revenue has been growing rapidly as local services digitize. The platform offers multiple ad formats — search ads, feed ads, listing promotions — all powered by AI matching. LongCat-2.0 changes three things:
1. Search understanding goes deep-context.
With a 1M+ token context window, LongCat-2.0 can understand a user's entire history — not just their last search — and match them to merchants with unprecedented precision. For advertisers, this means better targeting but also higher expectations for merchant-side content quality.
2. Review and content optimization becomes AI-driven.
Meituan's ecosystem generates massive user-generated content — reviews, photos, ratings. LongCat-2.0's ability to process this data at scale means the platform can better identify high-quality merchants and surface them in search results. Brands that invest in authentic, detailed merchant content will be favored.
3. Ad creative generation becomes native.
With strong code-agent capabilities, LongCat-2.0 can potentially auto-generate ad creatives, landing pages, and promotional content for merchants. This democratizes advertising on Meituan — small businesses can compete with professional marketing teams.
The Competitive Landscape
LongCat-2.0 positions Meituan in a distinct competitive space:
| Platform | AI Model | Primary Ad Context |
|---|---|---|
| Meituan | LongCat-2.0 (1.6T) | Local services search, food delivery, hotel booking |
| ByteDance/Douyin | Doubao ecosystem | Short video feed, e-commerce livestream |
| Tencent/WeChat | Hunyuan + WeLM | Social feed, mini-programs, official accounts |
| Baidu | ERNIE Bot | Traditional search, AI search, maps |
| Alibaba | Tongyi Qianwen | E-commerce search, cloud services |
| Kuaishou | Kling | Short video, livestream commerce |
Among these, Meituan has the most concentrated local services advertising ecosystem. A restaurant or hotel ad on Meituan converts directly to a delivery order or booking — the conversion loop is as short as it gets. LongCat-2.0's purpose-built architecture suggests Meituan is optimizing AI specifically for this high-intent, high-conversion environment.
What Brands Should Know
For international brands using Meituan for local services (hotels, restaurants, retail, entertainment):
Immediate actions:
| Action | Why |
|---|---|
| Audit merchant pages for AI readability | LongCat-2.0 processes content differently than previous models |
| Optimize review response strategy | AI-analyzed reviews affect search ranking more |
| Ensure structured data completeness | Opening hours, menus, pricing, location data |
| Test ad creative formats compatible with AI generation | Prepare for automated creative rotation |
Medium-term implications:
Meituan may follow DeepSeek's path toward API commercialization. If LongCat-2.0 offers API access to third-party developers, we could see a new ecosystem of AI tools built specifically for Meituan's advertising marketplace — similar to how GEO tools emerged for general AI search platforms.
Key Takeaways
1. Meituan's LongCat-2.0 is China's first trillion-level model trained entirely on domestic chips — a technical and geopolitical milestone.
2. 1.6T parameters + 1M token context window enables unprecedented understanding of user behavior and merchant content.
3. Local services advertising on Meituan will become more AI-driven — search ranking, ad matching, and creative generation all affected.
4. Meituan occupies a unique competitive position — the only major AI platform focused entirely on high-intent local services.
5. Brands should prepare now — audit merchant content, optimize for AI readability, and prepare for automated creative formats.
