What an AI coding cost tracker can honestly show
Token counts are not invoices. An AI coding cost tracker is useful when it says clearly which figures are provider-reported and which are local estimates. UsageAtlas does both: it uses a cost the tool reports when one exists, and otherwise estimates from token mix and bundled pricing.
That is enough to answer planning questions — which model carried the week, whether today is expensive against your own baseline, whether Cursor or Codex is doing the expensive work — without treating the dashboard as a billing system of record.
Tokens, cache, and model mix
Estimated spend follows the mix of fresh input, cache reads, cache creation, and output, and the models behind those tokens. UsageAtlas keeps that breakdown in the same view as the headline cost, so a spike can be traced to a model or a cache-heavy session instead of a single unexplained number.
History plots token load and tracked cost day by day. Insights show which models took the share and which hours of the week produced them.
Cost across Codex, Claude, Cursor, and OpenCode
A Claude-only CLI report or a Cursor settings page cannot show the combined cost of a mixed workflow. UsageAtlas adds supported sources into one running total, then lets you filter to a single tool when you need to attribute the spend.
Processing stays local. Prompts and responses are not read. Confirm any purchasing, accounting, or compliance decision with the provider invoice.
Questions, answered
Can UsageAtlas estimate AI coding cost from tokens?
Yes. When a supported tool does not report a cost, UsageAtlas estimates one from token counts and bundled pricing, and labels it as an estimate.
Is the tracked cost my actual bill?
Not by itself. Use provider billing records for final purchasing or accounting. UsageAtlas is a planning view of reported and estimated cost across supported tools.
Which tools are included in the cost total?
The running total includes every connected supported source: currently Codex, Claude, Cursor, and OpenCode. You can filter to one tool at a time.
