Using LLMs for Dialogue Management
The article explores practical patterns and architecture choices for using large language models (LLMs) as dialogue managers. It contrasts classical modular dialogue systems with LLM-based approaches that can reason over full transcripts and emit structured actions. Four production patterns are described: end-to-end generation, structured state extraction, tool-augmented manager, and hybrid classifier-LLM. The post gives prompt-engineering recommendations (system prompt as spec, JSON outputs, compressed memory), context/window management strategies (summarization, sliding window, external memory), and a code example using the OpenAI Python SDK pointed at Oxlo.ai with function-calling (model: llama-3.3-70b) to implement a tool-augmented e-commerce support flow. It also notes Oxlo.ai’s request-based pricing keeps per-turn cost flat regardless of prompt length. Publication date: 2026-06-17.
Practical, actionable guidance for building LLM-powered dialogue managers and a concrete SDK/code example; useful to product and engineering teams but not industry-shifting.

Key Takeaways & Evidence Grounding
- Article outlines four LLM-based dialogue management patterns: end-to-end generation, structured state extraction, tool-augmented manager, and hybrid classifier-LLM.
- Provides prompt engineering guidance: treat the system prompt as a specification, use JSON mode for structured outputs, and inject compressed memory for long conversations.
- Includes a code example using the OpenAI Python SDK against Oxlo.ai with function-calling and model 'llama-3.3-70b' to implement a tool-augmented e-commerce support agent.
- States Oxlo.ai uses request-based pricing, so cost per API request remains flat regardless of the amount of conversation history in the prompt.

Practical LLM Tutorial for Daily Developer Work
Rizwan Saleem published a practical tutorial (2026-05-29) on using large language models (LLMs) effectively in everyday developer workflows. The article outlines core principles (treat LLMs as artifact transformers, prefer small focused prompts, always perform structured reviews), specific prompt patterns (role prompts, atomized/single-purpose prompts, critic/referee prompts, self-check prompts), task decomposition strategies, model-selection guidance (using ChatGPT, Claude, Gemini as complementary tools), a professional checklist for reviewing AI-generated code (alignment, accuracy, completeness, risk), and repeatable practice exercises to build reliable habits.
AI Agents: When LLMs Take Actions
A technical tutorial describing goal-driven AI agents built on large language models. The article distinguishes reactive pipelines from agents that plan, call tools, observe results, and iterate (the ReAct pattern). It includes a Python example Agent class using the anthropic API (model reference: claude-3-5-haiku-20241022), a reusable tool library (calculator, web_search, time, file read/write, python_repl), guidance for planning agents, common agent failure modes and mitigations, an evaluation harness, and reference links to research papers and frameworks (ReAct, Toolformer, AutoGPT, LangChain, LlamaIndex, OpenAI Assistants API). The post is a how-to primer for engineers implementing multi-step, tool-using LLM agents.
Rasa Podcast: Dialogue Design in the LLM Era
A Rasa podcast episode of The Dialogue Architects features Rebecca Evanhoe (co‑author of Conversations with Things, Product Manager and Head of Conversation Design at Slang AI) discussing how conversational design has evolved with large language models (LLMs). Topics include Slang AI’s voice AI for restaurant phone bookings, a hybrid deterministic-vs-generative system design, strategies to reduce hallucinations (strict prompts and selective use of rules/APIs), new evaluation workflows (human-labeled ground truth, LLM-as-a-judge, and a trained evaluation model), operational constraints like ASR errors and latency in voice, and how conversational telemetry can produce prescriptive business insights for restaurants. Evanhoe argues that core conversation-design skills remain essential despite shifts toward prompt/context engineering.
