In short: Anthropic launched a faster, lower-cost artificial intelligence model called Claude Haiku 5.5. The company also introduced free monthly API credits for certain subscribers.

Finding a fast and affordable artificial intelligence model just got a bit easier for people who use these digital tools for work or projects.

What happened, in plain words

A technology writer named Simon Willison tested Anthropic's newly released artificial intelligence model, Claude Haiku 5.5. The model matches a competitor's pricing for smaller tasks and features built-in reasoning steps for generating images and text. Anthropic also announced that Max and Team subscribers will receive monthly digital credits to use on the Claude platform.

Key points

  • Matching competitor pricing: Claude Haiku 5.5 matches the price of OpenAI’s GPT-6 Luna for tasks up to 100,000 tokens, though prices increase for longer tasks.
  • Built-in reasoning: The new model includes reasoning levels that default to medium, allowing it to spend extra time thinking through complex tasks like drawing pelicans on bicycles.
  • Subscriber credits: Anthropic announced monthly platform credits for subscribers, ranging from $100 to $500 depending on the specific subscription plan.

Terms explained

  • Model — A computer program trained on massive amounts of data to understand instructions and generate text or images. Example: A smart assistant on your phone that answers questions.
  • Token — A small chunk of text, like a word or part of a word, that artificial intelligence programs read and write. Example: Breaking the sentence 'hello world' into smaller pieces for a computer to process.
  • API — A tool that lets different software programs talk to each other and share information. Example: A weather app on your phone asking a weather station computer for the daily forecast.

Why it matters

Lower prices and free monthly credits make it cheaper and easier for regular subscribers and developers to experiment with artificial intelligence tools.
