Indonesia’s e-commerce scene is expanding fast. Valued at around 65 billion USD today, it’s expected to reach 160 billion USD by 2030. By 2029, about 99 million users are projected to shop online. This growth creates a massive need for smart tools that understand the local market — especially Indonesian e-commerce LLMs that can handle the country’s language diversity and complex online behaviors.
How Language Shapes Indonesia’s Online Commerce
Indonesia’s e-commerce success depends heavily on communication. Online reviews, ads, and product descriptions are written in multiple languages — often a mix of Bahasa Indonesia, English, and local dialects. Research shows that 50.2% of app descriptions and 59.5% of online ads use Indonesian. This mix highlights the importance of Indonesian E-commerce LLMs, or multilingual tools, that not only translate but also understand local tone and culture.

That’s where multilingual LLMs (Large Language Models) come in. They process massive amounts of language data to help e-commerce platforms better understand, respond, and engage with their audiences.
Proving Local Language Mastery with Indonesian E-commerce LLMs
One strong example is IndoBERT, a transformer-based model built specifically for Indonesian. In tests, IndoBERT achieved an impressive 94.1% accuracy in classifying e-commerce reviews. It outperformed other machine learning models, proving that locally trained LLMs can read between the lines — identifying sentiment, context, and intent with remarkable precision.
This kind of analysis helps e-commerce businesses track satisfaction, predict trends, and personalize recommendations. For Indonesia’s many micro, small, and medium enterprises (MSMEs), it’s a competitive advantage. E-commerce already helps MSMEs increase revenue, expand their reach, and reduce costs. With localized AI like IndoBERT, these benefits grow even stronger.
The Rise of Domain-Specific AI Models in Indonesian E-commerce LLMs
The next big shift is happening with domain-specific LLMs — models built for a single purpose, such as e-commerce. Unlike general AI systems, they specialize in tasks like product search, recommendation, and customer interaction.
One of the leading examples is Compass-v3, a Mixture-of-Experts LLM with 245 billion parameters, trained on 12 trillion tokens of curated multilingual e-commerce data. It’s not just large — it’s deeply focused. Compass-v3 is designed to serve Southeast Asia’s digital economy, where language diversity and cultural nuance shape every interaction.
Currently, Compass-v3 powers Shopee’s platform, accounting for over 70% of its LLM usage. This specialization makes it more relevant and efficient than general-purpose models. In fact, Compass-v3 even outperforms GPT-4 in e-commerce-specific tasks, demonstrating how focus and optimization beat generality when the goal is precision and cultural relevance.
Why Multilingual and Domain-Specific Models Matter
Standard AI models often overlook Southeast Asian languages, with only 0.5% of Western model training data including them. By contrast, 13% of Southeast Asian LLM datasets include local languages, giving models like Compass-v3 a big advantage. They can understand not only Indonesian words but also how people use them in real contexts.
For users, this means better search results, smarter product suggestions, and more natural chatbot interactions. For businesses, it means higher engagement and conversion rates. Together, multilingual and domain-specific models are transforming Indonesia’s e-commerce into a smarter, more inclusive marketplace.
The Future of Indonesian E-commerce LLMs
The message is clear: Indonesia’s online commerce is thriving, and its future will be driven by localized AI. IndoBERT’s accuracy, Compass-v3’s scale, and the sector’s projected 160 billion USD value by 2030 all point to one thing — language-aware AI is becoming the foundation of growth.
