TrustList summary

  • Mid-tier position: sits in the middle tier of the Claude 5 line, alongside the other tiers.
  • Single window: all input, such as long documents or extended conversations, sits within one 1 million token window.

Key facts

  • Developer: Anthropic
  • Model line: Claude 5
  • Tier: mid-tier
  • Context window: 1 million tokens
