About Anthropic's Claude Models
Anthropic is an AI safety company founded in 2021 by former OpenAI researchers. Their Claude models are designed with a focus on being helpful, harmless, and honest, incorporating Constitutional AI training techniques that set them apart in the industry.
Claude Opus 4 is Anthropic's most capable model, excelling at complex analysis, extended reasoning, and nuanced writing tasks. At $15/$75 per million input/output tokens, it sits at the premium end but delivers top-tier benchmark performance. Claude Sonnet 4 offers an excellent balance of intelligence and cost at $3/$15, with a 64K max output window — the largest in the lineup.
For cost-sensitive workloads, the Haiku models offer strong performance at a fraction of the cost. Claude 3 Haiku remains one of the most affordable options at $0.25/$1.25 per million tokens. All Anthropic models support prompt caching, which can dramatically reduce input costs for repetitive system prompts and few-shot examples.
