Claude (Anthropic) offers Fable, Opus, Sonnet, and Haiku tiers for different cost/capability trade-offs — Fable is Anthropic's most capable generally-available tier as of the Claude 5 generation, with Opus, Sonnet, and Haiku filling out the cost/latency ladder beneath it. Known for long context (200k+), strong instruction following, reduced hallucination rates, and constitutional AI alignment. Claude excels at code generation, document analysis, and structured output tasks.
