How Ultra-Large Context Windows Challenge RAG

TL;DR for operators Ultra-large context windows are not a ceremonial funeral for retrieval-augmented generation. They are a price renegotiation. If your task is to analyse a bounded, self-contained document set — a contract bundle, diligence folder, policy manual, code repository, or technical appendix — a long-context model may now be the cleaner first option. The main benefit is not that it “knows more”. It is that it can inspect more of the original evidence without depending on a retriever to guess which passages matter. ...

Break-Even the Machine: Strategic Thinking in the Age of High-Cost AI

TL;DR for operators The real AI cost question is not “Which model is cheapest?” It is “Which workflow delivers acceptable outcomes at the lowest verified total cost?” Token price is only the most visible line item. The less photogenic costs are retries, review, integration, monitoring, compliance, vendor lock-in, and the small corporate tragedy known as “we saved money on inference and spent it all on fixing nonsense.” ...

The Slingshot Strategy: Outsmarting Giants with Small AI Models

TL;DR for operators Most organisations do not have an AI capability problem. They have an AI allocation problem. They send too many routine, repetitive, low-risk tasks to large frontier models because the demo looked impressive and the invoice arrived later. The slingshot strategy is the opposite instinct: break a workflow into smaller decisions, assign the cheap and reliable parts to specialised models or rules, and escalate only the uncertain or high-value cases to stronger LLMs. The point is not to worship small models. That would be merely replacing one superstition with a smaller, cheaper superstition. The point is to allocate model capacity like an operating resource. ...

Beyond the AI Hype: The Real Direction of AI Development

TL;DR for operators Enterprise AI is not becoming valuable because every company can now bolt a chatbot onto its website and call it “transformation.” That is transformation in the same way repainting a warehouse is supply-chain optimisation. The useful direction is narrower and harder: AI systems are becoming business intelligence layers that connect customer signals, workflow execution, financial planning, and strategic decisions. For a cross-border e-commerce company already using tools such as Duoke for customer service, translation, comment-context analysis, order follow-up, data visualisation, and logistics search, the next step is not “more AI features.” It is AI that improves profitability, cash-flow predictability, and market expansion decisions. ...
