Claude 3 \ Anthropic vs ChatGPT

Claude 3 is Anthropic's third-generation large language model family, released in March 2024. It includes three tiers: Haiku for speed and cost, Sonnet for balanced performance, and Opus for the highest reasoning depth. Each model targets a different tradeoff between intelligence, latency, and price.

The family handles text, code, analysis, and vision tasks. Claude 3 models process photos, charts, graphs, and technical diagrams. They support a 200K token context window at launch, with inputs exceeding 1 million tokens available to select customers. Opus and Sonnet launched on claude.ai and the Claude API in 159 countries, with Haiku following shortly after.

Anthropic built Claude 3 with Constitutional AI safety methods and Responsible Scaling Policy guardrails. The models are available through the Claude API, Amazon Bedrock, and Google Cloud Vertex AI. Sonnet powers the free tier on claude.ai, while Opus is available to Claude Pro subscribers.

ChatGPT is OpenAI's conversational large language model you reach through chatgpt.com on the web, iOS, and Android. You type or speak a prompt, and it answers in plain language, follows up on earlier messages, and can draft code, summarize files, generate images, or run multi-step research from one thread.

Where raw API access leaves wiring to you, ChatGPT bundles frontier GPT-5.6 models, memory, custom GPTs, voice, and agent workflows like ChatGPT Work and Codex behind a single login. The trade-off is less control over model parameters and tighter usage caps on Free and Go than you'd get calling the API directly.

It fits students drafting essays, developers debugging code, marketers shaping campaigns, and business teams that want shared workspaces with admin controls. OpenAI also publishes ChatGPT Business and Enterprise tiers with SSO, unified billing, and policies that keep workspace data out of model training.
