MODEL NOTES

Claude Haiku 4.5 is Anthropic's fast, affordable model — and on Apiarium, it's priced closer to the budget tier than you might expect from Anthropic directly. It comes with a 200,000 token context window, which is far larger than GPT-4o mini's, making it a strong choice when you need to process longer documents, conversation histories, or codebases without upgrading to a pricier model.

Anthropic's models tend to follow instructions more literally and write with a slightly more careful, structured tone than OpenAI's — useful if your product needs consistent, predictable output formatting.

A practical default for production text tasks where GPT-4o mini works but you want more context headroom, or where you specifically want Claude's writing style.
