Developer shares 3 costly OpenAI API mistakes and a cost-tracking tool

A developer shares three costly mistakes made when using the OpenAI API, focusing on cost management. The first mistake involves overlooking the impact of 'temperature' and 'max_tokens' settings, which can lead to unexpectedly high costs for high-volume tasks. The second pitfall is failing to track API costs per user, leaving businesses unaware of who their most expensive users are. The third error is using the most powerful models, like GPT-4, for tasks that could be handled by cheaper alternatives such as GPT-3.5 Turbo, resulting in significant overspending. To address these issues, the developer created an open-source dashboard called LLMeter to provide real-time cost monitoring per model and user. AI
