Just switch out gpt-4o-mini for gpt-4o, the point stands. Across the board, these foundational model companies have comparable, if not more powerful, models that are cheaper than their older models.
OpenAI's own words: "GPT-4o is our most advanced multimodal model that’s faster and cheaper than GPT-4 Turbo with stronger vision capabilities."
gpt-4o:
$2.50 / 1M input tokens $10.00 / 1M output tokens
gpt-4-turbo:
$10.00 / 1M input tokens $30.00 / 1M output tokens
gpt-4:
$30.00 / 1M input tokens $60.00 / 1M ouput tokens
I found that gpt-4-turbo beat gpt-4o pretty consistently for coding tasks, but claude-3.5-sonnet beat both of them, so it's what I have been using most of the time. gpt-4o-mini is adequate for summarizing text.
