  "price": "Per token. Opus 5 $5/$25 per M in/out; Sonnet 5 $2/$10; Haiku 4.5 $1/$5; Fable 5 and Mythos 5 $10/$50. Batch API 50% off; cache reads 0.1x input.",
  "tier": "paid",
  "pick": false,
  "what": "Anthropic's first-party API for the Claude models, plus the Agent SDK, tool use, MCP connectors, files and batch endpoints. This is a <b>model provider</b>, not a gateway — you get the models Anthropic trains and nothing else, with prompt caching and batch as the main cost levers.",
  "why": "Best-in-class coding and agentic tool use, and the only place to get Claude with full feature support. Prompt caching at 0.1x read cost makes long system prompts and big codebase context genuinely affordable.",
  "warn": "Output tokens cost 5x input, and extended thinking bills as output — a reasoning-heavy agent loop can 10x your bill versus the naive estimate. Tier-based rate limits throttle new accounts hard.",
  "install": "npm i @anthropic-ai/sdk (or pip install anthropic)",
