OLMo 2 is an open-weight model with no managed endpoint — you run it on your own GPUs, so the cost depends on your hardware choice rather than a per-token price. Hosted providers like Together AI, Fireworks, or Replicate offer it from around $0.20–$2.00 per 1M tokens depending on size.
OLMo 2 has a 4,096-token context window (small memory — a few emails or a short document). That means you can fit about 768 words of input and history in a single call.
