Strengths

  • Priced from $0.10 input / $0.50 output per 1M tokens for prompts up to 100K tokens
  • Adaptive thinking with an effort parameter, 1M-token context and 128K output
  • Available on the Claude API, Amazon Bedrock, Google Cloud and Microsoft Foundry

Considerations

  • Prompts over 100K tokens cost five times more per token
  • New tokenizer counts the same text as roughly 30% more tokens than Haiku 4.5

Price
