# AI Stack

> **TL;DR.** An AI stack is the layered set of components that turns raw compute into a shippable AI product — chips and models at the bottom, data and orchestration in the middle, the application on top.

## Definition

An AI stack is the layered set of components that turns raw compute into a shippable AI product — chips and models at the bottom, data and orchestration in the middle, the application on top. Menlo Ventures' January 2024 [modern AI stack post](https://menlovc.com/perspective/the-modern-ai-stack-design-principles-for-the-future-of-enterprise-ai-architectures/) hardened the framing.

Two years later every major player talks in stack terms. [NVIDIA's March 2026 "5-Layer Cake"](https://blogs.nvidia.com/blog/ai-5-layer-cake/) added energy as Layer 1; Apple's [Foundation Models framework](https://developer.apple.com/documentation/FoundationModels) pitched macOS 26 as a full on-device AI stack; and Forbes' January 2026 "AI stack trap" piece warned that overbuilding the stack is now its own hidden cost.

## Example

A canonical 2026 enterprise AI stack: Anthropic or OpenAI models at the top of Layer 1, Pinecone + Unstructured for data (Layer 2), Modal or Baseten for deployment (Layer 3), and Braintrust or LangSmith for observability (Layer 4) — the exact shape Menlo Ventures sketched and that Databricks, Snowflake, and MongoDB now extend from below.

## Analogy

The model is the chef; the stack is the kitchen, the runners, the dining room, and the power keeping them all on.

## Why it's emerging now

Two years after Menlo Ventures hardened the four-layer framing, "AI stack" is the default shorthand every vendor reaches for — and April 2026 marks the pivot from what goes in it to whether teams are overbuilding it. NVIDIA, Apple, and Forbes all published stack-framed pieces within eight weeks.
