Concise monthly summary for 2026-03 focusing on business value and technical achievements for BerriAI/litellm. The main deliverable this month was a critical fix to Whisper pricing and cost calculation that ensures transcription is billed based on input duration. Updated the pricing logic so cost_per_second evaluates input and output costs independently and added unit tests to validate arithmetic. No new customer-facing features shipped this month; however, the corrected pricing model improves billing accuracy, cost transparency, and revenue protection for Whisper models (whisper-1 and azure/whisper-1). This work lays groundwork for more accurate cost tracking and reduces the risk of revenue leakage in future pricing scenarios.
