Choosing the right AI provider can save you time, money and headaches. While OpenAI's GPT-4o Mini is known for its impressive capabilities (including vision), there are many other platforms - such as Together.ai or Fireworks.AI - with comparable pricing structures. Which option is right for you often depends on how many tokens you feed (input) versus how many tokens the model generates (output).
Understanding Input vs. Output
Input Tokens: The text you send to the model (questions, instructions, data).
Output Tokens: The text the model returns as a response.
Most AI platforms charge you separately for input and output tokens. When your usage is asymmetric—that is, if you’re generating a lot more output than you’re supplying as input—some services could end up costing significantly more than others.
Cost Comparison Example (10k Input / 5k Output)
Let’s compare OpenAI’s GPT-4o Mini to Together.ai’s 8B model using a hypothetical job (e.g. summarizing data from the Web) with 10,000 input tokens and 5,000 output tokens:
This cost calculation is based on the current prices in AI as of 12/24.
