AI Buzzwords, Demystified: What They Really Mean for Ecommerce Teams

This is an AWS & Constructor webinar recap post. Watch the full webinar here.

AI buzzwords are flying around in ecommerce, but they’re not always clear. Terms like “foundational models,” “GenAI,” and “agentic AI” can make your eyes glaze over.

In our recent webinar, David Dorf, Global Head of Retail Solutions at AWS, and our own Eli Finkelshteyn, Founder and CEO at Constructor, unpack the lingo and got down to what it all really means for retail teams:

  • Foundational models: Large AI systems trained on massive datasets that can be adapted for a variety of tasks
  • Domain-specific models: AI models trained on your industry data (product attributes, clickstream behavior, and purchase history)
  • Generative AI: AI that can create new text, images, video, and code
  • Multimodal models: Generative AI that can generate assets combining images, voice, and video
  • Agentic AI: AI that can perform actions based on instructions
  • Model context protocol: An open-source standard that acts as a universal interface to connect AI agents to different tools and data sources and instruct them on how to act

You can catch the webinar replay here. In the meantime, here are some key takeaways from the discussion.

Foundational Models: The New AI Baseline

Foundational models are large AI systems trained on massive datasets — text, images, code, and more — that can be adapted for a variety of tasks. They’re the underlying intelligence behind tools like ChatGPT, advanced search engines, and recommendation platforms.

Why they matter in ecommerce

Unlike older keyword or basic vector search, foundational models understand context, not just similarity. A traditional search for “butter” might also return “margarine” because they’re semantically close. But if a user types “Find me a flight from Boston to London,” older systems often failed to understand the directionality, treating “Boston” and “London” interchangeably. Foundational models, built on transformer architectures, interpret the relationship between terms and return results that match intent.

This leap in contextual understanding improves:

  • Search relevance: interpreting complex, long-tail queries like “red waterproof hiking boots for winter” accurately.

  • Product discovery: combining multiple attributes in a way that feels intuitive to the shopper.

  • Content generation: creating copy or recommendations that match the shopper’s needs and tone.

The net effect: better alignment between what shoppers mean and what your platform delivers.

Domain-Specific Models: From “Next Best Word” to “Next Best Action”

While general-purpose foundational models are versatile, they’re not optimized for ecommerce’s unique challenges. That’s where domain-specific models come in. They're trained on your vertical’s data, like product attributes, clickstream behavior, and purchase history.

domain-specific models

Example:

A general model predicts the next best word in a sentence. An ecommerce-trained model predicts the next best action. If a shopper buys organic milk and bread, the model can suggest organic strawberries — understanding the purchase pattern rather than just keyword overlap.

Benefits for ecommerce teams:

  • Sharper recommendations based on real shopper behavior.

  • Better ranking logic that aligns with both relevance and business goals.

  • Infrastructure efficiency by focusing the model’s knowledge on what matters most.

Because they’re trained on proprietary behavioral data, these models often outperform general AI in driving conversion rates, increasing basket size, and lifting revenue.

Generative AI: Past the Peak of Hype

Generative AI (GenAI) can create new text, images, video, and code, enabling faster content creation for ecommerce teams. In practice, this means:

  • Writing product descriptions and headlines.

  • Enriching product catalogs with missing attributes.

  • Generating on-brand banners or ad creative.

  • Automating customs paperwork or internal documentation.

ROI in action:

  • One retailer cut catalog onboarding time by 50% by using GenAI to extract attributes from product images.

  • Another saved $4M annually by automating customs forms.

Key takeaway: GenAI doesn’t need to be perfect to be valuable. When targeted at use cases that either improve the customer experience or boost productivity, the payoff can be significant.

Multimodal Models: Beyond Text

The next wave of foundational and generative models is multimodal, capable of handling text, images, voice, and video.

Examples from AWS:

  • Nova Sonic: voice-enabled AI for fast, spoken interactions (e.g., drive-through ordering or warehouse fulfillment)

  • Nova Canvas: image manipulation for product visuals, seasonal backgrounds, or virtual try-on

  • Nova Reel: short-form product video generation, driving engagement and conversions

For merchandising teams, multimodal AI enables:

  • Scalable creative production without overloading design teams.

  • Personalized media that tailors the version of an image or video shown based on shopper data.

  • Reduced returns by helping customers visualize products in context.

Personalization: The Next Frontier

As AI makes it easier to generate multiple variations of product copy, images, or videos, there’s a great opportunity to expand personalization from product recommendations to fully personalized product pages — content and all.

Imagine dynamically swapping product images to reflect the shopper’s demographic or browsing history, or adjusting the tone of descriptions to match their buying motivations. While not mainstream yet, this is where personalization is headed. And early experimentation now will pay dividends later.

Agentic AI: From Assistant to Autonomous Actor

If GenAI creates content, agentic AI acts. These systems can reason about a goal, break it into steps, and execute those steps (often with minimal human input).

Defining traits of agentic AI

  1. Semi-autonomous: able to complete tasks on its own

  2. Reasoning ability: can plan steps toward a goal

  3. Tool/data access: can pull from catalogs, APIs, or analytics

Use cases in ecommerce

Pricing: Gathering demand data, competitor pricing, and brand guidelines to recommend optimal prices

Search & Discovery: Interpreting open-ended queries (“I’m camping on Mount Whitney”) and factoring in weather, terrain, and inventory to recommend gear

Product Page Q&A: AI agents that auto-generate FAQs and answer customer-specific questions in real time

Inbound Agents: Bots visiting your site on behalf of shoppers, requiring a strategy for data accessibility and optimization

Outbound Agents: Personal shoppers that source products you don’t carry and fulfill under your brand

agentic-ai-use-cases-in-ecommerce@2x

Model Context Protocol (MCP): The Agent’s Bridge to Action

MCP connects AI agents to tools and data sources, telling them what they can use and how. For example, in the Mount Whitney scenario, an MCP-enabled agent could:

  1. Look up the location.

  2. Check local weather.

  3. Query the product catalog for suitable sleeping bags.

MCP also allows retailers to deliver real-time, personalized data to inbound agents, potentially tailoring results for each digital visitor, whether human or AI.

Where Retailers Should Start

Phase 1 — Quick Wins

  • Use foundational and Generative AI for catalog enrichment, product description writing, and attribute completion.

  • Focus on measurable ROI with minimal disruption to your existing tech stack.

Phase 2 — Competitive Differentiation

  • Experiment with agentic AI for richer, more guided shopping experiences.

  • Pilot tools like natural language shopping assistants or product insights agents.

Build vs. Buy?

Both experts agreed: Buy unless you have an extremely unique use case. AI innovation is moving too fast for most internal teams to keep up, and switching vendors is easier than unwinding a stalled internal build.

Bottom Line

Foundational models have redefined what’s possible in search and product discovery. Domain-specific training pushes performance even further. Generative and multimodal AI expand creative capacity and personalization. And agentic AI promises to transform ecommerce from reactive transactions to proactive, goal-oriented experiences.

The real opportunity lies in moving past buzzwords and starting with the practical, high-ROI use cases that make a difference for your team and your customers today.
