Vendor export guides, and honest writing on AI spend

Where each export actually lives, what its real columns mean, and where a naive sum gets the cost wrong. The Cursor and Claude Team guides are written from real, verified export files; the Anthropic Console guide documents the columns our parser accepts and says so on the page; the model-choice essay runs synthetic data through the real pipeline. None of it is vendor marketing.

• Export Cursor usage as CSV (and what Included vs Usage-based means) 2026-08-30 The real 13-column header, and why Kind — not a flat token count — decides what you were charged. Cursor export · 13 columns Date,User,Cloud Agent ID,Automation ID,Kind,Model,Max Mode,Input (w/ Cache Write),Input (w/o Cache Write),Cache Read,Output Tokens,Total Tokens,Cost
• Claude Team spend report CSV, explained 2026-08-30 One row per person/product/model for the whole window — gross vs net, and the overlapping-export trap. Claude Team export · 17 columns user_email,account_uuid,product,model,total_requests,total_prompt_tokens,total_completion_tokens,total_net_spend_usd,total_gross_spend_usd,user_id,total_uncached_input_tokens,total_cache_read_tokens,total_cache_write_5m_tokens,total_cache_write_1h_tokens,total_web_search_count,slack_channel_id,teams_channel_id

• The right model for the task: why defaulting to the priciest model is the wrong habit, even when it's cheap 2026-08-30 Synthetic data, run through the real pipeline: request share and dollar share point in opposite directions. sample-report.json · headline top_family_share: 0.3645 · top_family: claude-sonnet · top_family_by_usd: claude-opus · top_family_usd_share: 0.2944
