Building Custom LLM Interfaces with Square Codex and Text Generation WebUI
Text Generation WebUI
Running language models locally is becoming increasingly accessible thanks to powerful open-source tools. Among these, Text Generation WebUI stands out as a flexible and user-friendly interface that allows developers to load, test, and fine-tune LLMs on their own machines. At Square Codex, we help companies harness tools like Text Generation WebUI to create AI applications that are customized, scalable, and deployed with full control over infrastructure.
From prototype to production, our nearshore development teams offer the hands-on expertise required to integrate this platform into your workflows. Whether you’re building internal tools, intelligent assistants, or full-fledged AI products, we ensure seamless implementation of locally served models.
What Makes Text Generation WebUI Effective
Text Generation WebUI is an open-source graphical interface designed to simplify interaction with locally run LLMs. It supports a variety of backends including GPT-J, LLaMA, Falcon, Mistral, and others, making it one of the most versatile interfaces available.

At its core, the platform allows users to configure prompt templates, tweak inference settings, and even run fine-tuned models through a clean, customizable web-based interface. Our engineers at Square Codex use this platform to help clients experiment with different configurations, allowing rapid iteration without relying on cloud APIs.
Empowering Private Deployments Through Local Interfaces
Security and compliance are major concerns when dealing with sensitive data. That’s why more businesses are turning to on-premise LLM solutions. Text Generation WebUI enables organizations to deploy AI models behind their firewall with complete control over data flow.
Square Codex specializes in setting up these secure environments. Our nearshore developers understand the intricacies of model loading, quantization, performance tuning, and hardware optimization. We don’t just implement tools — we align them with your business goals and technical constraints.
Customization that Drives Real Results
The true power of this interface lies in how deeply it can be tailored. Prompt presets, personality modules, and chat-style output can be adapted to create branded assistants or internal tools that reflect your company’s voice and needs.
