We price per GB of ingested trace - $0.3/GB, goes lower as you scale.

Traditional APM spans are ~2KB - this would come to ~$0.6/million spans.

How we arrived at $10 is that we assumed each agent span is ~35KB. Which means 1M spans is ~35GB - which comes to ~$10. Agent spans are larger because they have large prompts.

If your LLM spans are smaller, the cost would be lower. For our customers we see this vary between 20-30KB, and we took a conservative 35KB number.
