On June 24, at the FORCE Power Conference, ByteDance officially released the Doubao 2.1 Pro large model, with core metrics that shook the industry: programming capabilities on par with Anthropic's Claude Opus 4.7, and overall usage costs reduced by nearly 80% compared to the Claude Opus 4.6–4.8 series. At the same time, the company previewed that its video generation model Seedance 2.5 will officially launch in early July, supporting single-video generation of up to 30 seconds. WeChat's AI assistant "XiaoWei" simultaneously began small-scale beta testing, marking ByteDance's AI ecosystem's full-scale penetration from the "model layer" to the "application layer."
"80% Cost Slash": The "Value-for-Money Revolution" of Chinese Large Models
Doubao 2.1 Pro's pricing strategy continues the "ultimate cost-performance" approach of Chinese AI vendors:
| Dimension | Doubao 2.1 Pro | Claude Opus 4.7 | Gap |
|---|---|---|---|
| Programming Capability | On par | Baseline | Tied |
| Overall Cost | 80% reduction | Baseline | 1/5 the cost |
| Token Call Volume | 10x+ YoY growth (as of June) | — | Explosive growth |
| Video Generation | Seedance 2.5 (30 sec / early July) | No direct competitor | Differentiated |
This "80% cost slash" is not simply a price war, but a systematic cost reduction based on ByteDance's self-developed chips (in collaboration with Pingtou Ge), Volcano Engine compute optimization, and model architecture innovation. As of June 2026, Doubao's token call volume has grown over 10x year-over-year, validating the effectiveness of the "low price for scale" strategy.
WeChat "XiaoWei": An Entry Point Revolution from "Mini Programs" to "AI Skills"
WeChat has rolled out its biggest update ever—the AI assistant "XiaoWei" has entered small-scale beta testing, with core features including:
Base model: Tencent WeLM (not Doubao—highlighting WeChat ecosystem's independence)
Feature coverage: Voice/text command execution for conversations, document reading, transfers, and Moments management
Mini-program transformation: Mini-programs transition from "standalone apps" to "Skills" that can be invoked by AI, supporting services like food ordering and ride-hailing.
This means WeChat's 1.3 billion monthly active users will gradually enter the era of "AI-native interaction"—users no longer open individual mini-programs one by one, but simply tell "XiaoWei," "Order me the highest-rated spicy hotpot nearby," and the AI automatically invokes the Meituan mini-program to complete the order.
Conclusion
ByteDance's "dual-engine" strategy (Doubao models + Seedance video + WeChat XiaoWei) is forging the strongest closed loop in China's AI ecosystem. Doubao 2.1 Pro's "80% cost slash" is not an isolated event, but a systematic advancement of the Chinese AI industry's "open-source + low-cost + ecosystem" strategy—alongside DeepSeek-V4-Pro's 75% price cut, Alibaba's Qwen3.7-Max ranking first in 12 domestic evaluations, and Zhipu's GLM-5.2 topping CodeArena globally—all collectively mounting a "cost restructuring" assault on the Western closed-source, high-margin business model.
WeChat "XiaoWei's" beta launch carries even greater strategic weight: while US AI assistants (Siri, Alexa, Google Assistant) are still struggling for "entry-point" status, WeChat already possesses a ready-made super-app gateway. Mini-programs evolving from "apps" to "skills" signals that China's internet ecosystem is shifting from "people finding services" to "AI matching services"—this is not a technology upgrade, but a revolution in interaction paradigms. However, challenges remain: the technical gap between WeLM and Doubao, controversies over WeChat ecosystem's closed nature, and privacy boundaries around AI-invoked mini-programs will all face scrutiny once "XiaoWei" is fully rolled out.
