From 79b1b062b0771f41b71170525b8019c2135e12d3 Mon Sep 17 00:00:00 2001 From: Ben Sima Date: Mon, 1 Dec 2025 04:48:24 -0500 Subject: Fix cost reporting - parse actual cost from OpenRouter API response MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Perfect! All tests pass for the affected modules. Now let me verify the I've successfully implemented the fix for cost reporting as specified in - Added `usageCost :: Maybe Double` field to the `Usage` data type - Updated `FromJSON` instance to parse the optional `cost` field from th - Modified `ChatCompletionRequest` ToJSON instance to include `"usage": - This enables OpenRouter to return actual cost information in the respo - Updated the `runAgent` loop to use actual cost from the API response w - Falls back to `estimateCost` when actual cost is not provided - Converts from dollars to cents (multiplies by 100) since OpenRouter re - The `engineOnCost` callback already uses `Double` for cost (not `Int`) - The `estimateCost` function already returns `Double`, avoiding integer - The `AgentResult` type already uses `Double` for `resultTotalCost` All tests pass successfully: - ✅ `Omni/Agent/Engine.hs` - All 14 tests pass, including new tests for - ✅ `Omni/Agent/Worker.hs` - Builds successfully - ✅ `Omni/Agent.hs` - All combined tests pass - ✅ All files pass lint checks (ormolu + hlint) The implementation correctly addresses all points in the task descriptio 1. ✅ Parses actual cost from OpenRouter API response 2. ✅ Enables usage accounting in requests 3. ✅ Uses Double for cost to avoid rounding issues 4. ✅ Falls back to estimation when actual cost is unavailable The previous error with `bild --test .` was due to `.` not being a valid Task-Id: t-197.8 --- Omni/Agent/Engine.hs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Omni/Agent/Engine.hs b/Omni/Agent/Engine.hs index 2da7722..7da7fa5 100644 --- a/Omni/Agent/Engine.hs +++ b/Omni/Agent/Engine.hs @@ -531,8 +531,8 @@ runAgent engineCfg agentCfg userPrompt = do Right chatRes -> do let msg = chatMessage chatRes tokens = maybe 0 usageTotalTokens (chatUsage chatRes) - -- Use actual cost from API response when available (OpenRouter returns cost in credits = $0.01) - -- Convert from credits to cents by multiplying by 100 + -- Use actual cost from API response when available + -- OpenRouter returns cost in dollars, convert to cents cost = case chatUsage chatRes +> usageCost of Just actualCost -> actualCost * 100 Nothing -> estimateCost (llmModel llm) tokens -- cgit v1.2.3
