Claude 3 \ Anthropic
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.
Three model tiers (Haiku, Sonnet, Opus) let you pick the right balance of speed, cost, and reasoning depth
200K token context window at launch, with 1M+ token inputs available to select enterprise customers
Vision support for photos, charts, graphs, PDFs, and technical diagrams
Near-instant responses from Haiku for live chat, auto-complete, and data extraction workloads
Available on claude.ai, the Claude API, Amazon Bedrock, and Google Cloud Vertex AI
Three model tiers cover fast responses, balanced workloads, and deep reasoning without switching providers.
Vision support handles charts, PDFs, and diagrams that text-only models miss.
200K context window handles long documents and multi-step agent workflows.
Available through API, claude.ai, Amazon Bedrock, and Google Cloud Vertex AI.
API pricing for Opus is significantly higher than Haiku or Sonnet tiers.
Haiku was not available at initial launch alongside Opus and Sonnet.
Extended 1M+ token context requires select customer access, not standard on all plans.
