Your End-to-End LLM Application Partner
91 QUANTS is a Singapore-based AI company focused entirely on Large Language Model applications. We do not just experiment with models — we architect, build, deploy, and maintain production systems that real users rely on every day.
Our team combines deep expertise in prompt engineering, retrieval-augmented generation (RAG), fine-tuning, agent frameworks, and LLM infrastructure. Whether you need a proof-of-concept in two weeks or a scalable platform serving millions of requests, we deliver.
We support models from OpenAI, Anthropic, Google, Meta, and open-source communities — always selecting the right tool for your specific use case, budget, and compliance requirements.
Full-Stack LLM Capabilities
From architecture design to production support, we cover the entire LLM lifecycle.
LLM Application Development
End-to-end development of AI-powered applications using GPT-4, Claude, Llama, and other frontier models. From chatbots to complex reasoning systems.
RAG & Knowledge Systems
Build enterprise-grade retrieval-augmented generation pipelines. Connect your documents, databases, and APIs to LLMs with accurate, grounded responses.
AI Agent Frameworks
Design autonomous agents that plan, execute, and iterate. Tool-use, multi-step reasoning, and workflow orchestration for complex business processes.
Model Fine-Tuning
Customize open-source models for your domain. Instruction tuning, RLHF, and parameter-efficient methods like LoRA and QLoRA for optimal performance.
LLM Infrastructure & Ops
Deploy, monitor, and scale LLM workloads. Cost optimization, latency reduction, caching strategies, and fallback systems for production reliability.
Ongoing Support & Consulting
Long-term model maintenance, prompt versioning, evaluation frameworks, and strategic advisory to keep your AI capabilities ahead of the curve.
Real Problems, Real LLM Solutions
Every project below is a live system we designed, built, and continue to support.
