How much can your claude.ai team save by moving from Anthropic to open-weight models? One click for Owners, all in your browser. costmaxxing shows how much your claude.ai team can save by moving from Anthropic to open-weight models. Install it while signed in to claude.ai as an Owner of a Team or Enterprise organization. Your team's report opens in a new tab right away: the last 30 days of usage priced at Anthropic's API rates, next to the same usage on a tiered open-weight plan (GLM-5.3, GLM-5.3 Flash, and DeepSeek V4.1 Flash). The report shows: - yearly and monthly savings on open-weight models - what your seats cost against what the usage is worth at API prices - cost by person, by product, and by model - the same plan priced at several inference providers Click the toolbar button for a quick view at any time, and use Download CSV to keep the spend report. Members who aren't Owners can't read the spend report, so the extension tells them the team view needs an Owner. Everything runs in your browser. The extension reads your organization's spend report from claude.ai with your own session and public prices from models.dev. It sends nothing anywhere else and has no analytics.
