Multi-Agent Orchestration: Semantic Kernel vs AutoGen vs LangGraph

Semantic Kernel, AutoGen, and LangGraph represent three genuinely different bets on how multi-agent systems should be structured. This decision guide covers orchestration models, state management, production-readiness, and how to match the right framework to your problem — before you commit to an architecture you will live with.

Multi-Model Routing: Cut LLM Costs Without Sacrificing Quality

Multi-model routing sends each AI request to the cheapest model capable of handling it well, rather than routing everything through a frontier model. Combined with semantic caching and fallback chains, it is one of the most effective ways to control LLM costs in production without degrading quality. This post covers the core patterns and what a practical production architecture looks like.

Open-Source vs Proprietary LLMs: When to Self-Host

Self-hosting open-weight models like Llama or Mistral gives Australian teams data residency, cost control at scale, and deployment flexibility — but it comes with real infrastructure and operational tradeoffs. This post works through when each approach makes sense, with a practical framework for mid-market teams deciding between open-weight self-hosting and proprietary APIs like GPT-4 or Claude.

Digital Engineering Consultancy Australia: Beyond AI — The Full Stack

A digital engineering consultancy works across the full technology stack — applications, data infrastructure, cloud platforms, DevOps, and AI — delivered as a coherent system. In the Australian mid-market, that integration is what separates technology investments that compound from those that stall. This article explains what the full stack looks like, why fragmented delivery fails, and what an end-to-end Australian consultancy actually does.

Application Modernisation: The Strangler-Fig Pattern in Practice

Rewriting a legacy monolith from scratch is high-risk and rarely necessary. The strangler-fig pattern lets Australian engineering teams modernise .NET and Java applications incrementally — shipping value continuously while reducing risk. Here is how it works in practice.
