Rationale
- OpenAI's Apache 2.0 open-source small model, commonly used for low-cost classification and extraction; absolute prices remain low, but the increase is significant
Usage
- For cost-sensitive batch calls, you can specify a provider or self-host the open-source weights
Risk
- OpenRouter displays the current lowest provider price, which may fluctuate and potentially decrease again as providers change
