OpenWebUI Pipelines
Getting Started, Setup, Pitfalls, and First Pipeline
Open WebUI is not just a chat frontend for OpenAI-style APIs—it also supports Pipelines, a plugin framework that lets you add custom logic, RAG workflows, filters, and integrations directly into the system.
Hard vs Soft Boundary Conditions in PINNs: What's the Difference and Why It Matters
In traditional numerical methods, boundary conditions are enforced rigidly — the solution must satisfy them. But in Physics-Informed Neural Networks (PINNs), enforcing boundary conditions is not always straightforward. There are two fundamentally different ways to handle them: hard and soft enforcement.
Why Classic RAG Fails for Scientific Papers — And What To Do Instead
Retrieval-Augmented Generation (RAG) has become the go-to architecture for building intelligent assistants using large language models. It works incredibly well in use cases like customer support
LLMs Don’t Break Loudly — They Drift Silently: Why Prompt Validation Is the Missing Guardrail in AI Systems
A product manager asked: “Can you summarize the return policy for electronics?” The assistant replied confidently: “Returns are allowed within 7 days if the product is unopened.” Except the policy said 14 days.
Same Input, Different Output: How LLM Drift Silently Broke Our Production Pipeline
A user asked our assistant: “List all customers who placed orders in the last 30 days.” The backend used GPT to generate the SQL: SELECT * FROM orders WHERE order_date >= '2024-04-01'; It worked. The next day, the same prompt returned: SELECT * FROM orders WHERE order_date >= '2024-04-01' AND status = 'shipped'; No warning. No error. Just a new condition the user never asked for.
