Datadog LLM Observability adds tiered overage pricing for LLM spans
What happened
Between the May 11, 2026 and May 18, 2026 captures of Datadog's pricing page, Pulse recorded 2 changes: Pro plan card now displays overage pricing explicitly: 'Additional spans: $3.5 per 10K LLM spans.' Span inclusion bullet updated to '100K LLM spans per month included'. FAQ expanded with 3 overage tiers: $3.5 annual, $4.20 M2M, $5.00 on-demand; Pro plan tagline updated from 'For teams running in production' to 'For teams at scale', broadening the described audience. Pulse files it as a pricing change (price revealed, positioning) with an upward direction. Pulse's latest capture (Sep 28, 2026) lists Pro at $160, 90-Day Retention Add-on at $9, 30-Day Retention Add-on at $6.5 and 60-Day Retention Add-on at $8.
It lands 14 days after Datadog's previous change, "Datadog Llm Observability launches Free tier and $160/mo Pro, ditches per-request" (May 4, 2026). Before that Pulse recorded "Datadog Llm Observability announces new LLM Observability pricing from May 1" (Apr 27, 2026). Datadog has been tracked since 2023-11-14.
In the same window Grafana, New Relic and Dynatrace also changed their Cloud & DevOps pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
