Kakao Brain vs OpenAI

OpenAI has a disclosed valuation of $852B, while Kakao Brain's valuation is not publicly available, making a direct size comparison difficult. OpenAI employs 4,000 people.

OpenAI has raised more in total funding at $127B, compared to Kakao Brain's $100M — a gap of $126.9B. Combined, the two companies have completed 10 known funding rounds.

OpenAI leads with an Awaira Score of 98/100, while Kakao Brain sits at 58/100. That 40-point gap reflects real differences in funding, scale, and traction — it's not a vanity metric.

Kakao Brain was founded by Kim Il-doo in 2017. OpenAI was founded by Sam Altman in 2015. Visit each company's profile on Awaira for a full founder biography.

Kakao Brain: Kakao Brain is the AI research and foundation model division of Kakao Corp, the dominant Korean internet and messaging platform company, developing large language models including KoGPT for Korean language, the Karlo text-to-image generation model, and AI infrastructure for deploying AI capabilities across the Kakao platform ecosystem spanning KakaoTalk messaging, KakaoPay, and Kakao Mobility. The Seongnam company operates as a corporate AI research unit with internal funding from Kakao Corp.\n\nFunded internally through Kakao Corp with estimated investment exceeding $100 million across research infrastructure, compute, and personnel, Kakao Brain develops AI capabilities that are deployed to the KakaoTalk base of over 50 million monthly active users in Korea and across Kakao enterprise and government client deployments. The unit has released open-weight Korean language models through the Hugging Face platform, contributing to the Korean open-source AI ecosystem.\n\nKakao Brain competes in Korean AI research and model deployment with Naver AI, Samsung AI, and LG AI Research, as well as international AI labs whose models must be adapted for Korean language performance. Its integration with KakaoTalk provides a unique distribution mechanism for consumer AI features, as KakaoTalk functions as South Korea primary social communication platform and an essential interface for daily life services from banking to government. The corporate research structure gives Kakao Brain resources and stability but limits the commercial independence and equity-based talent attraction that independent foundation model startups use to recruit researchers. OpenAI: OpenAI is an artificial intelligence research laboratory founded in 2015 and headquartered in San Francisco. The company develops and deploys large language models and foundation models that power conversational AI applications. Its flagship product, ChatGPT, launched in November 2022 and rapidly became one of the fastest-adopted applications in technology history, reaching 100 million users within two months. OpenAI also offers GPT-4, a more advanced language model, and provides API access to developers through its platform. The company operates in the foundation models category, competing directly with Anthropic, Google DeepMind, and Meta in developing transformer-based large language models. OpenAI's approach emphasizes training increasingly capable models using large datasets and computational resources. Notable applications include content generation, coding assistance, customer service automation, and research support across enterprises and consumer markets. OpenAI has secured substantial funding from diverse sources including Microsoft, which invested $13 billion, making it one of the most heavily funded AI companies. The company's valuation reached $500 billion as of recent funding rounds, reflecting investor confidence in the commercial potential of large language models. The organization transitioned from a non-profit structure to a capped-profit model to facilitate venture capital investment. Growth has accelerated significantly following ChatGPT's release, expanding its user base and enterprise adoption substantially. OpenAI created one of the first large language models to achieve mainstream consumer adoption through ChatGPT, establishing a dominant position in accessible AI applications.

OpenAI got there first, launching in 2015 — that's 2 years of extra runway. Kakao Brain didn't arrive until 2017. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Kakao Brain has about 100-500 employees; OpenAI has about 4,000. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both Kakao Brain and OpenAI compete in Foundation Models, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
