The claim that getting on Tier 2 is the answer to huge delays makes common sense but I am on Tier 1 and I’ve reviewed the rate limits for that tier and GPT-3.5-Turbo. It is totally impossible that my chatbot is getting anywhere near those limits.but I’m getting 30 sec and up delays, occasionally more than 100 sec. If needing Tier 2 is the answer then it certainly isn’t explained by OpenAI documentation!
