OpenAI

OpenAI, co-founded by Sam Altman in 2015 and headquartered in San Francisco, develops foundation models and AI products including ChatGPT, Codex, GPT Image 2, API models, and open-weight gpt-oss models. The company holds a $1.2 trillion valuation as of April 2026 following a $122 billion funding round 5.

Key Facts

What They Do

OpenAI trains large foundation models and packages them through consumer products, developer APIs, enterprise deployments, and open-weight releases. ChatGPT is the main consumer interface. Codex is the coding-agent surface. GPT Image 2 is the current OpenAI image-generation model inside ChatGPT and the API. The open-weight gpt-oss line serves teams that need self-hosting or customization 6.

The strategic pattern is clear: keep ChatGPT as the default user-facing assistant, push Codex and agents into developer and enterprise workflows, and distribute models beyond a single cloud or application surface. That makes OpenAI less dependent on one product route, but it also means buyers need to evaluate which surface they are actually using: ChatGPT tiers, the API, managed cloud deployments, or open-weight models.

Current Flagship Products

• ChatGPT: General-purpose assistant for text, research, data analysis, images, browsing, voice, Codex, and agent workflows. AIpedia’s ChatGPT record currently lists GPT-5.5 as the flagship model and tracks tier-specific context and pricing in canonical facts.
• Codex: Agentic coding workflow inside the OpenAI ecosystem, with higher usage on Pro and team plans.
• GPT Image 2: Current OpenAI image-generation model for ChatGPT Images 2.0 and API use, replacing DALL-E as the current OpenAI image surface.
• gpt-oss-120b: Open-weight model for data centers and customization 6.

Recent News

• May 2026: The Pentagon expanded classified-network AI access to eight major vendors, including OpenAI. This increases the importance of enterprise auditability and government-access boundaries.
• April 2026: GPT-5.5 rolled out to ChatGPT and Codex, updating the current ChatGPT and OpenAI model-access picture.
• April 2026: ChatGPT Images 2.0 and gpt-image-2 launched, making GPT Image 2 the current OpenAI image-generation surface.
• April 2026: OpenAI raised $122 billion for compute expansion and global AI deployment 5.
• 2026: OpenAI introduced gpt-oss open models for self-hosting and customization 6.

Strategic Position

OpenAI’s moat is the combination of model velocity, ChatGPT distribution, Codex developer workflows, enterprise access, and capital for compute. The main buyer risk is not whether OpenAI matters. It is choosing the right surface and plan. Consumer ChatGPT, ChatGPT Business, the OpenAI API, managed cloud distribution, and gpt-oss deployments have different pricing, control, privacy, and integration tradeoffs.

For AIpedia readers, OpenAI should be treated as the default benchmark vendor for general assistants and agentic workflows, not as the best fit for every narrow task. Claude still competes strongly on long-form writing and conservative enterprise safety posture. Gemini remains the deepest Google Workspace option. Midjourney and specialist image tools can still beat OpenAI on pure aesthetics. Perplexity remains a cleaner first stop for citation-first research.
