fast for volume · pro for everyday production · ultra for the hardest problems. Not sure? Start with avelin-pro. Capabilities and selection guide: Model Catalog.

Prompt caching: repeated prompt prefixes (system prompts, documents, history) are billed once at the cache write rate, then at the cache read rate on every reuse — roughly 5× below input on the pro and ultra tiers, and 10× below on all three fast tiers.

Legacy names: avelin-coding, avelin-coding-plus, avelin-coding-architect, avelin-agentic, and avelin-agentic-high still work and are billed as their renamed models.
