Company Field Guide · One Line to Remember Each

OpenAI

USA · ChatGPT / GPT series / Sora

The company that brought AI into the mainstream. ChatGPT is the world's most-used AI app, and the video model Sora comes from them too.

Anthropic

USA · Claude series

Founded by former OpenAI researchers, known for safety and long-context work. Claude has an especially strong reputation in coding and Agent scenarios, long dominating the global Agent blind-test leaderboard.

Google

USA · Gemini / Veo / Imagen

The old aristocracy of AI research (the Transformer architecture came from a Google paper). The Gemini family covers text, images, and video, and the video model Veo is in the world's top tier.

Meta

USA · Llama / Muse series

Facebook's parent company and the standard-bearer of open source — giving strong models away free to everyone, which profoundly reshaped the industry.

xAI

USA · Grok series

Founded by Elon Musk and deeply tied to X (formerly Twitter). Bold in style, extremely fast to ship, with image and video generation in the works too.

Mistral

France · Mistral series

Europe's standard-bearer — the classic case of a small team punching far above its weight, hugely popular in the open-source community.

A few "shovel sellers" are worth knowing too: NVIDIA (nearly every model is trained on its chips — one of the AI era's biggest winners), Microsoft (OpenAI's biggest backer, with AI built into the whole Office suite), and Amazon (cloud services + an investor in Anthropic). They don't necessarily build the strongest models themselves, but the entire industry stands on their foundations.
📊 Company landscape as of August 2026. This industry moves extremely fast — the names will change, but the structure of "model companies + shovel sellers" will be around for a long time.
