OpenAI

OpenAI is the AI research company that launched the current generative AI revolution with ChatGPT in November 2022. Founded in 2015 as a nonprofit by Sam Altman, Elon Musk, and others, the company has since restructured as a Public Benefit Corporation and raised more than $168 billion in total funding at a roughly $852 billion valuation — making it the most valuable private AI company in the world. NVIDIA holds a $30 billion commitment to OpenAI, the largest single investment in private-AI history. OpenAI has confidentially filed a draft S-1 with the SEC for an initial public offering — Goldman Sachs, Morgan Stanley, and JPMorgan are leading the offering, with a potential listing window in the fall of 2026.

OpenAI develops the GPT family of language models, with GPT-5.6 as the current flagship — a family split into Sol, Terra, and Luna capability tiers, generally available July 9, 2026 across ChatGPT, Codex, and the API. The prior flagship GPT-5.5 features a 1 million token context, native computer use, and unified reasoning, and remains widely available. GPT-5.5 ships in three variants (standard, Thinking, Pro) and posts headline benchmarks including 82.7% on Terminal-Bench 2.0 and 84.9% on GDPval. Beyond ChatGPT (more than 400 million weekly active users, now with automatic long-term memory that synthesizes context across conversations and full-duplex GPT-Live voice) and the Codex coding agent (3 million+ weekly users), OpenAI ships GPT Image 2 — the first image model with built-in reasoning, character-level multilingual text rendering, and 2K resolution at up to 8 images per prompt. In July 2026 OpenAI also launched ChatGPT Work, an agentic product powered by GPT-5.6 that turns a goal into finished sheets, slides, docs, and web apps — gathering context across a team's connected tools and working autonomously for hours rather than just answering questions. Tier pricing covers Free, Go ($8 per month), Plus ($20 per month), Pro ($200 per month), Business ($25–30 per user per month), and Enterprise.

Product strategy is unified under co-founder Greg Brockman, who is consolidating ChatGPT, Codex, and the developer API into a single platform aimed at agentic workloads. Distribution runs through multiple horizontal channels: Microsoft (the original $13 billion+ partner and primary cloud anchor since GPT-3), Apple (ChatGPT integrated in iOS), and Amazon Bedrock (where OpenAI's frontier models are now available alongside Anthropic, Meta, and Mistral after Microsoft's exclusive cloud rights ended). OpenAI for Countries extends this multi-channel posture into a sovereign-AI tier — the inaugural deal makes Malta the first country in the world to offer free ChatGPT Plus to every citizen and resident, framing ChatGPT as a public-good utility alongside libraries and public broadband.

OpenAI competes head-to-head with Anthropic and Google DeepMind as one of the three US frontier labs, racing on agentic capability, multimodal performance, and enterprise distribution. OpenAI is also integrating downward into its own hardware: with Broadcom it unveiled Jalapeño, its first custom AI chip — a reticle-sized accelerator built for inference that OpenAI says runs at roughly half the cost of today's leading GPUs, taped out in about nine months, with deployment beginning at the end of 2026 — a bid to loosen its dependence on Nvidia. The Microsoft multi-cloud rebalancing signals a structural shift in the partnership that defined OpenAI since the GPT-3 era, and the prospective IPO will set up a head-to-head financial event with the parallel SpaceX offering. OpenAI's consumer scale — more than 400 million weekly ChatGPT users — remains the company's most durable strategic advantage versus rivals whose enterprise and developer footprints are larger relative to their consumer ones.
