Companion to #143 which fixed the frontend to use Claude Opus 4.6 as the sole baseline. This migration recomputes existing Supabase rows using the exact closed-form: new = T/3.8M + 10*old/19, derived from the original triple-provider formula.

-- Migration: Recompute dollar_savings to use only Claude Opus 4.6 pricing
|
|
-- -----------------------------------------------------------------------
|
|
-- Previously the frontend summed hypothetical costs across all 3 cloud
|
|
-- providers (GPT-5.3 + Claude Opus 4.6 + Gemini 3.1 Pro). This
|
|
-- migration recalculates dollar_savings using Claude Opus 4.6 only.
|
|
--
|
|
-- Derivation
|
|
-- ----------
|
|
-- Let P = prompt_tokens, C = completion_tokens, T = total_tokens = P + C.
|
|
--
|
|
-- old = (P/1M)*(2+5+2) + (C/1M)*(10+25+12) = (P/1M)*9 + (C/1M)*47
|
|
-- new = (P/1M)*5 + (C/1M)*25
|
|
--
|
|
-- Solving the system {T = P + C, old = 9P/1M + 47C/1M} for P and C and
|
|
-- substituting into the "new" formula gives:
|
|
--
|
|
-- new = T / 3_800_000 + 10 * old / 19
|
|
--
|
|
-- Run this in the Supabase SQL Editor (Dashboard > SQL Editor).
