I've found this mostly to be the case when using lightweight open source models or mini models.
Rarely is this an issue with SOTA models like Sonnet-4.5, Opus-4.1, GPT-5-Thinking or better, etc. But that's expensive, so all the companies use cut-rate models or non-existent TTC to save on cost and to go faster.
