Introducing GitLab Credits

Introduces GitLab Credits as a new virtual currency for usage-based pricing of GitLab Duo Agent Platform capabilities, replacing seat-based pricing for agentic AI. Details how credits are pooled, consumed by various agents and flows (foundational, external, custom), and how consumption is calculated based on LLM requests. Outlines cost governance features including sizing calculators, usage visibility dashboards, usage controls, and automated notifications. Explains the upgrade path for existing Duo Pro/Enterprise customers and provides a competitive comparison to seat-based pricing.
