During the initial generative AI wave, many enterprise engineering teams in the US and UK built conversational workflows and internal copilots using the OpenAI Assistants API. While the Assistants API simplified early prototyping by bundling message thread management, retrieval, …
Human-in-the-Loop AI Agents: Implementing Approval Breakpoints in LangGraph
Fully autonomous AI agents are powerful, but deploying them in production without safety boundaries is dangerous. An autonomous agent equipped with database write permissions, payment gateway APIs, or shell execution tools can easily hallucinate bad arguments, wipe customer data, or …
Quantizing and Running DeepSeek-R1 with Ollama, llama.cpp, and GGUF in Python
The release of DeepSeek-R1 has transformed open-source artificial intelligence. By matching or exceeding OpenAI o1 on complex reasoning, mathematics, and code generation benchmarks while publishing complete weights and distillation architectures (from 1.5B to 70B parameters), DeepSeek-R1 has made enterprise-grade reasoning …
Building a Multimodal RAG Pipeline in Python with Qdrant and CLIP Embeddings
Standard Retrieval-Augmented Generation (RAG) pipelines are built exclusively for textual data. They parse markdown files, split paragraphs into token chunks, calculate dense text embeddings, and index them into stores like PostgreSQL with pgvector.…
Building an Agentic SQL Data Analyst in Python with DuckDB and LangChain
In enterprise data analytics, querying relational warehouses has traditionally required specialized SQL knowledge or static business intelligence dashboards. With modern generative AI, organizations are transitioning to autonomous Text-to-SQL data agents capable of translating ambiguous business questions into valid SQL queries, …
Handling Tool Calling Errors, Retries, and Fallbacks in Autonomous AI Agents with Python
In autonomous artificial intelligence systems, Large Language Models (LLMs) do not operate in a vacuum. To perform real-world work, agents rely on tool calling (also known as function calling) to inspect production databases, execute shell commands, retrieve live API payloads, …
Connecting Claude & AI Agents to Custom Local MCP Tools in Python
The release of the open-source Model Context Protocol (MCP) by Anthropic has fundamentally solved the fragmented landscape of AI tool calling. Before MCP, connecting an LLM to your local database, developer terminal, or internal API required writing bespoke integration …
Deploying DeepSeek-R1 and Llama 3.3 Locally with vLLM and Docker
The release of open-weights frontier reasoning models like DeepSeek-R1 and high-parameter foundational models like Llama 3.3 70B has triggered a massive shift in AI infrastructure. While hosted proprietary APIs charge per token and introduce strict data privacy concerns, running models …
FastAPI Streaming LLM Responses with Server-Sent Events (SSE) in Python
In modern AI applications, users should never stare at a blank screen waiting 10 seconds for a full 500-token response. Streaming tokens in real-time as they are generated by the model is the expected UX standard.…
Reranking in RAG Pipelines: When and How to Use Cross-Encoders vs Bi-Encoders
Retrieval-Augmented Generation (RAG) performance is bounded by the quality of the context supplied to the LLM. If your retrieval step introduces irrelevant documents (false positives), the language model either hallucinates or produces diluted, unfocused answers.…
