Anthropic¶
Overview¶
Anthropic was founded by former OpenAI researchers with a mission to build safe AI systems. Their Claude models represent the state-of-the-art in safety-aligned language models.
Model Timeline¶
- Claude 1 (2023) - Initial release, focused on safety
- Claude 2 / 2.1 (2023) - Improved reasoning, extended context
- Claude 3 (2024) - Three variants: Opus, Sonnet, Haiku with multimodal support
Key Differentiators¶
Constitutional AI - Training with AI feedback based on principles Safety First - Reduces harmful outputs significantly Long Context - 200K token window (read entire books) Multimodal - Vision understanding (Claude 3+)
Family Overview¶
| Model | Size | Speed | Cost | Best For |
|---|---|---|---|---|
| Opus | 200B | Moderate | Premium | Maximum quality |
| Sonnet | 55B | Fast | Moderate | Production balance |
| Haiku | 8B | Very Fast | Budget | High-volume applications |
