Poolside AI

Poolside AI is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Poolside AI rather than just read about it. In short: Poolside AI (or Poolside) is an American artificial intelligence company that develops large language models for computer software and coding applications. History Poolside AI was founded in early 2023 by Jason Warner, former CTO of GitHub, and Eiso Kant, a software entrepreneur.

Key takeaways

Poolside AI belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Poolside AI to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Poolside AI from memory before moving on to harder problems.

Reference excerpt

Poolside AI (or Poolside) is an American artificial intelligence company that develops large language models for computer software and coding applications.

History Poolside AI was founded in early 2023 by Jason Warner, former CTO of GitHub, and Eiso Kant, a software entrepreneur. The company started with a work from home model and had employees in the United States, United Kingdom and France. The first phase of Poolside's Project Horizon, a 2-gigawatt artificial intelligence campus located in Pecos County, Texas, started in October 2025. The data center will be one of the largest in the United States. As of December 2025, Poolside has 150 employees worldwide. It is headquartered in San Francisco and invites its employees to a monthly concentrated work week at its Paris branch.

Funding Within its first year, Poolside secured seed funding of $26 million, followed by an additional $100 million funding round. In October 2024, the company raised $500 million in a Series B funding round led by Bain Capital, DST Global and eBay, among others, which brought its valuation to $3 billion. Poolside had shown a demonstration of its code assistant to these investors using the prompt "Write me the code for a snake video game in python". In October 2025, Nvidia announced that it would invest up to $1 billion in Poolside which would quadruple its valuation to $12 billion.

Models Poolside released the 118-billion-parameter open-weights large language model Laguna S 2.1 in July 2026 under the OpenMDW license. At the time of release, co-CEO Warner stated that the company intended to develop larger models.

Partnerships In December 2024, Poolside and Amazon Web Services (AWS) announced a partnership to provide AI products on Amazon Bedrock and Amazon Elastic Compute Cloud. This partnership allows businesses to deploy Poolside's foundation models within their existing AWS environment. Poolside has signed contracts with the United States Department of Defense, RTX Corporation, and other companies in the American defense industrial base, while working to sell its autonomous software development engine to Israeli defense companies.

Activity The company competes in two sectors with other AI companies, building both large language models and autonomous development products. Poolside's software uses natural-language prompts from developers to create and test code, and the company's models are specifically designed for software development instead of general tasks. A system called Model Factory is used to train Poolside's models and evaluate the outcome of the training.

Worked examples

Example 1 — a first encounter with Poolside AI

Start with the simplest possible case. Write down what Poolside AI claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Poolside AI before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Poolside AI ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Poolside AI

In research: Poolside AI appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Poolside AI in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Poolside AI is common in secondary-school and first-year university syllabi. It links to neighbouring topics American companies established in 2023, Artificial intelligence companies, so understanding it makes those chapters shorter.
In everyday life: Look for Poolside AI outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Poolside AI in simple terms?

Poolside AI (or Poolside) is an American artificial intelligence company that develops large language models for computer software and coding applications. History Poolside AI was founded in early 2023 by Jason Warner, former CTO of GitHub, and Eiso Kant, a software entrepreneur.

Why does Poolside AI matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Poolside AI?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
