Meet Siam AI
Powering Cultural AI Independence
Thailand’s premier sovereign AI cloud partners with WEKA to deliver breakthrough performance for its intelligent, indigenous AI cloud services, serving 70 million people nationwide.
How Siam AI Built Thailand’s First Sovereign Cloud to Compete Globally
Siam AI is Thailand’s first sovereign AI cloud provider—a groundbreaking achievement that has positioned it as the country’s leading AI service provider.
However, on the path to innovation, CEO Ratanaphon Wongnapachant and his team wanted to do more than build generic AI models. The company is committed to developing a truly culturally aware AI service to enhance its understanding and support of Thailand’s people and businesses.
“When we founded Siam AI, our vision was to build Thailand’s first sovereign AI cloud and develop Thai-based large language models (LLMs) that truly understand our language, culture, and unique context.”
“We wanted to develop the LLMs ourselves, trained on our native language, rather than relying on foreign-developed models. Otherwise, we would have risked losing valuable data that could be used for cognitive development, an essential foundation for the country,” Mr. Ratanaphon explains.
With major partnerships for Thai LLM development, enterprise AI solutions, and tourism AI agents, Siam AI is already successfully serving enterprises, researchers, universities, and government agencies. However, to truly scale their vision and deliver the extreme performance their advanced AI models demanded, they needed highly performant, adaptive, and resilient infrastructure that could seamlessly scale with their ambitious vision and support cutting-edge NVIDIA accelerated computing.
The Challenge
Meeting Ambitious Requirements for End-to-End AI Performance Excellence
To support their growing innovations and expanding customer base, Siam AI established demanding infrastructure requirements:
- Multi-petabyte storage that could scale linearly with GPU growth
- Sustained millions of IOPS at sub-millisecond latency across 100+ clients simultaneously
- Fast and frequent checkpointing to maximize GPU productivity during training
- Rapid deployment to meet urgent market demand
- Performance, simplicity, and reliability without traditional storage architecture complexity and costs
These weren’t just technical specifications—they were the foundation needed to achieve their goals.
“To bring this vision to life, we needed an AI infrastructure platform that could keep pace with our ambition — delivering extreme performance, scalability, and efficiency at every layer.”
The Solution
A Strategic Choice: NeuralMesh by WEKA
After evaluating numerous AI storage options, Siam AI selected NeuralMesh as its storage foundation.
The collaboration between Siam AI and WEKA’s engineering and customer success teams ensured a seamless 54-node cluster deployment—demonstrating not only the power of WEKA’s technology, but also the depth of our partnership and unwavering post-deployment support, as Siam AI’s innovation converged with WEKA’s technical excellence to deliver a world-class AI infrastructure built for performance and scale.
- Aggregate Performance: ~3 TB/s reads, ~1.5 TB/s writes
- Latency: <0.5 ms with millions of IOPS
- Client Scale: Seamless access for up to 140 GPU clients
“With WEKA, we were able to stand up a production-ready AI storage platform in just four days — something that would have normally taken weeks or even months,” explains CTO Nutthapong Chuaybumrung.
“The results have been extraordinary: linear scaling across multi-petabyte nodes, each GPU client driving up to 40 GB/s throughput and more than 2 million IOPS at sub-millisecond latency.”
The Outcomes
Accelerating Thailand’s AI Ambitions
With WEKA’s NeuralMesh storage system powering its infrastructure, Siam AI transformed its cloud services platform.
“WEKA gives us exactly the foundation we need, ensuring our GPUs run at near-full utilization and our researchers and engineers can focus on innovation rather than infrastructure bottlenecks,” Mr. Ratanaphon notes.
Key Achievements with NeuralMesh
Simplicity of Setup
Production-ready in just 4 days, proving WEKA’s ease of deployment and reliability.
Performance at Scale
Linear scaling across 54 nodes with
no bottlenecks.
Peak Client Performance
Each GPU client achieves up to 40 GB/s reads and writes and over 2 million IOPS at <0.3
ms latency.
Optimized Infrastructure
Delivered in only 54 rack units, powered by 108 × 400 GbE connections.
Sustainability Leadership
Industry-leading performance per kilowatt and the most balanced performance per terabyte, maximizing efficiency while reducing environmental impact.
Building a National AI Infrastructure Platform
“Beyond raw performance, WEKA has given us the most balanced efficiency per terabyte and per kilowatt we’ve seen in the industry, allowing us to scale sustainably without compromise,” Mr. Nutthapong explains. “WEKA doesn’t just keep up with our most demanding AI workloads — it makes storage invisible, so our teams can focus on innovation, not infrastructure.”
By deploying WEKA at scale, Siam AI has created a national AI infrastructure platform that delivers:
- Checkpointing in minutes, not hours, enabling faster recovery and iteration
- Higher GPU utilization, reducing idle time and improving ROI
- Reliable, low-latency performance for massive AI training jobs
- National impact, positioning Thailand as a regional leader in AI innovation
“I would recommend NeuralMesh by WEKA to any organization facing the same AI infrastructure challenges we encountered. With WEKA, storage simply disappears from the equation, allowing our teams to focus on building AI innovation instead of wrestling
with bottlenecks.”
Creating Real
World Impact
Siam AI is extending its platform to support emerging workloads and broader access across Thailand and beyond, including:
- High-performance inference at scale
- Local AI development environments for researchers and startups
- Sovereign AI initiatives for enterprises and government
- Next-generation use cases in healthcare, manufacturing, fintech, and smart cities
As one of only four Asian countries—alongside China, Japan, and South Korea—developing indigenous LLMs, Thailand’s position in the global AI landscape continues to strengthen.
“With WEKA powering our AI infrastructure, we can move beyond experimentation into real-world impact,” Mr. Ratanaphon reflects. “From building Thai LLMs that preserve our cultural identity to enabling new services in healthcare, tourism, and other critical sectors, this transformation opens doors we could only imagine before. The future of sovereign AI in Thailand is just beginning, and we’re excited to lead it.”
With NeuralMesh as its infrastructure foundation, providing performance, simplicity, and scale, Siam AI has transformed its platform to compete globally while serving locally. As Thailand rises in the global AI readiness rankings and Siam AI hosts one of Asia’s most advanced accelerated computing infrastructures, the foundation is set for continued innovation and leadership.
