Changes
This PR adds documentation for three new AI cost metadata properties that were added in PostHog/posthog#49219:
$ai_model_cost_used- The model identifier used for cost calculation (may differ from the requested model when a variant or alias is resolved)$ai_cost_model_source- Where the cost data for this model was sourced from (openrouter,manual,custom,passthrough)$ai_cost_model_provider- The provider used to look up the cost for this model (openai,anthropic,custom)These properties help users debug cost discrepancies and understand which pricing was applied when using model aliases or custom configurations.
Note: The other two properties from the PR (
$ai_request_cost_usdand$ai_web_search_cost_usd) were already documented on the calculating-costs page.Related PR
