- Audio speech usage API: curl "https://api.openai.com/v1/organization/usage/audio_speeches?start_time=$TIMESTAMP&project_ids=$PROJECT_ID&group_by=model"

Fri, Sep 19, 2025. I understand at least one mechanism of how costs are inflated in large organizations. Even people who want to keep costs low find that the process of tracking expenses, submitting receipts, answering questions around approval, adds transaction cost. So, rather than going for a $10 plus top up mechanism, I would rather go for and ask people to take a $500 top up. Better ask for more and waste than have to ask again. #pricing

Sun, May 25, 2025. Here's one way controls inflate cost. Tracking expenses, submitting receipts, and justifying usage adds transaction cost. So, rather than a $10 monthly top-up, I'd rather top-up $200 (even if it might go unused), rather than have to ask again. #pricing

Wed, Dec 18, 2024. GPT 4o Mini Realtime was released. A realtime conversation will cost ~50c/hr. About 36c for input, 72c for output. (I extrapolated from the 6c/min audio input cost for GPT 4o Realtime when it was $100/MTok. GPT 4o Mini Realtime is $10/MTok input and $20/MTok output.) #chatgpt #pricing #speech-to-text #tts

Wed, May 22, 2024. Predibase lets you run fine-tuned models at the same price, on a per-token basis. 25c/MTok up to 21B models. That's sames as Claude 3 Haiku, but with fine-tuning. #markdown #pricing

Thu, Feb 15, 2024. Shubha: Media sites are moving away from Vickrey auctions to first-price auctions for ads. That's because they send the auction price forward to a search engine and the winning second-price value can lose even though the owner is willing to pay more. Second-price auctions don't work unless ALL bidders are in the SAME auction. Ad networks are a hierarchy of auctions! #pricing

Thu, Dec 7, 2023. Anyscale prices the 7b Llama2, Zephyr, Mistral models at 15 cents per 1M tokens. Roughly 1/10th of GPT-3.5 Turbo's ~$1.5 per 1M tokens #pricing
