Talk Smarter to Me: The Rise of Context Engineering for Actually Useful AI

In partnership with

Today we’re diving into “context engineering,” the newest evolution in human-AI communication that replaces prompt hacks with structured, persistent context. Plus: AWS flexes its infrastructure muscles, Lambda takes on NVIDIA, and AI stocks save Wall Street’s bacon.

Let’s get into it.

Don’t get SaaD. Get Rippling.

Hundreds of apps create silos, wasted time, and missed opportunities. Rippling replaces SaaD (Software as a Disservice) with one system to run HR, IT, and Finance – without the drag.

Take a stand against SaaD today.

Context is King: One New Framework is Turning Bad Prompts into Gold

Remember when "prompt engineering" was the hottest skill to check resumes for? Well, the newest most important thing to pay attention to is context engineering: a structured way of giving LLMs persistent, situationally relevant information to reduce hallucinations, improve output quality, and ditch the prompt spaghetti.

Researchers at the Shanghai AI Lab found that context engineering can significantly boost AI performance without the need to retrain the model. By enriching prompts with structured, situational context, their tests showed improvements in relevance, coherence, and task completion rates. This approach builds on traditional prompt engineering, but expands it into a more comprehensive framework, essentially designing the entire interaction environment to guide AI behavior more effectively.

So, in essence, they’re saying that most AI implementations fail not because the models are bad, but because humans are terrible at talking to them.

How it works:

The research paper, “Context Engineering 2.0: The Context of Context Engineering,” builds on this key idea: Don’t tell the model what to do. Show it what world it’s operating in. And that it’s less about crafting perfect prompts and more about building intelligent conversation scaffolding. Think of it as the difference between shouting directions at a tourist versus handing them a detailed map with landmarks circled.

Instead of writing a long prompt each time, engineers now feed the model:

• System-level instructions (role, tone, formatting).

• Input-output pairs (examples of what “good” looks like).

• Memory snippets (recent interactions or customer history).

• Constraints (rules or limits, like “don’t summarize confidential info”).

Together, this forms a Context Stack, which can be reused and adapted like modular code. The research shows that by structuring context hierarchically (background info → specific parameters → desired format), users can improve AI output quality by up to 40%.

The framework breaks down into three layers:

1. Domain Context: Feed the AI your industry's peculiarities upfront.

2. Task Parameters: Specify constraints, compliance needs, output formats.

3. Dynamic Adjustments: Let the system learn from feedback loops.

Microsoft's already integrating similar principles into Copilot for enterprise customers. Oracle's rumored to be building context libraries for industry-specific deployments.

For those of us that can adapt this practice, research suggests we will see:

1. Faster QA: Less rework, fewer hallucinations.

2. Multimodal gains: Works across text, vision, and code.

3. Better grounding: Easier to control tone, compliance, and formatting.

Early adopters are already seeing better reliability in legal, customer service, and RAG-based document search without needing to fine-tune models or rewrite prompts every week.

News Roundup

1. AWS wants your GenAI workloads.
   Amazon is now offering custom-built infrastructure for open-source and proprietary AI models, including support for NVIDIA, AMD, and its homegrown Trainium chips. Translation: AWS wants to be the Switzerland of AI compute.

TL;DR:

• Context engineering is replacing prompt hacks with reusable “context stacks” that improve output, reduce risk, and scale better.

• Anthropic’s new paper outlines how to structure AI inputs like code modules. Great news for product and R&D teams.

• AWS is going chip-agnostic, offering full-stack support for open-source and commercial models alike.

• Lambda raised $320M to expand its GPU cloud and go toe-to-toe with NVIDIA and AWS.

• AI stocks are holding up the market, but the rest of the economy isn’t joining the party.

Context is the new prompt. Structure is the new hack. And in this new world of AI-native infrastructure, how you feed your model matters as much as which one you choose.
