The short answer
Anthropic is the company behind Claude. OpenAI is the company behind ChatGPT.
The practical difference is narrower than the headlines suggest. Both companies build frontier AI models, sell chat products, offer developer APIs, and work with enterprises. Anthropic’s public identity is more tied to AI safety, reliable model behavior, long-context work, and enterprise trust. OpenAI has the larger consumer brand through ChatGPT and a broader public platform presence.
- Anthropic: maker of Claude
- OpenAI: maker of ChatGPT
- Relationship: separate companies
- History: Anthropic was founded by former OpenAI staff

What Anthropic actually is
Anthropic is an AI research and product company that builds the Claude family of models and the Claude assistant. It was started by former OpenAI employees, including Dario Amodei and Daniela Amodei. The company describes its mission around building AI systems that are capable, reliable, and aligned with human interests.
Anthropic competes with OpenAI in consumer AI assistants, enterprise AI, and developer APIs. Its brand posture is different. Anthropic often explains its work through Constitutional AI, model evaluations, responsible scaling, interpretability, and enterprise trust documentation.
The official Claude product is claude.ai. The developer platform is platform.claude.com. The company site is anthropic.com. Those names are not interchangeable: Anthropic is the company, Claude is the model and product brand, and claude.ai is the app most people use.
People and leadership
Anthropic is closely associated with its founding team. That matters in the Anthropic vs OpenAI comparison because the companies share some early talent history, but they now have separate products, investors, policies, and technical cultures.
Dario Amodei is Anthropic’s chief executive officer and one of its co-founders. He is the company’s most visible executive voice on frontier model risk, responsible scaling, and Anthropic’s long-term direction.
Daniela Amodei is Anthropic’s president and one of its co-founders. Her public role is tied to company operations, policy, and institutional growth.
Jared Kaplan is a co-founder and a prominent technical leader associated with Anthropic’s research direction. Mike Krieger is publicly associated with product leadership and the effort to make Claude useful for consumers, developers, and companies.
Anthropic is easier to understand when
- You see it as the company behind Claude, not as the Claude app itself.
- You separate research, API products, and consumer subscriptions.
- You compare companies, models, and products separately.
Avoid this shortcut
- Do not treat Anthropic and Claude as identical in every context.
- Do not assume OpenAI and Anthropic share governance, pricing, or product policies.
- Do not rely on old model names when comparing current capabilities.
Leadership is not the same as product quality. A company’s founders explain why it exists and how it talks about risk. Buyers should still compare the live products. Check model availability, usage limits, pricing, uptime, support, and admin features before making a business decision. Anthropic publishes service information at status.claude.com.

The visible routes are clear: individual subscriptions, team seats, enterprise seats, API token usage, and custom business agreements. For Claude-specific buying details, use the official Claude pricing page and our Claude pricing overview.
| Model | Input price | Output price | Notable limit |
|---|---|---|---|
| Claude Opus 4.7 | $5 per million tokens | $25 per million tokens | 1M context |
| Claude Sonnet 4.6 | $3 per million tokens | $15 per million tokens | 1M context; 128K max output |

90% off
cached input tokens with prompt caching
Cost optimization can change the comparison. Anthropic supports prompt caching, which gives 90% off cached input tokens. The Batch API gives 50% off in both directions. For developer details, use Anthropic’s API pricing docs and our Claude API guide.
OpenAI competes across similar categories: consumer chat, business subscriptions, API access, enterprise deployment, and developer tooling. The better vendor depends on the job. A legal team may care about long-document handling. A developer team may care about SDKs, latency, coding performance, and deployment controls. A marketing team may care about writing style, file handling, and collaboration features.

FAQ: other questions readers ask
These are the related questions people usually mean when they search for Anthropic vs OpenAI.
The honest take
Anthropic vs OpenAI is not a simple “which company is better?” question. Anthropic is a serious OpenAI competitor with a safety-led identity, a strong Claude product line, and credible developer and enterprise offerings. OpenAI has the larger consumer footprint through ChatGPT and a broad public platform presence.
If you are choosing a tool, compare Claude and ChatGPT with your own prompts, files, policies, and budget. If you are choosing a vendor, compare trust documents, enterprise controls, support, pricing, data handling, uptime, and procurement requirements. Anthropic is not OpenAI, Claude is not ChatGPT, and the right choice depends on the work you need the model to do.
