The cheapest GPT model to use in Clay is no longer GPT-4o mini. Currently, the most cost-effective option is Claygent Helium. It outperforms both Haiku and GPT 4o-Mini in terms of price-performance ratio.
For those looking to minimize costs, GPT 3.5 is mentioned as the default option and is significantly cheaper than models like GPT-4 Turbo and Claude.
Keep in mind that using AI features with Clay-managed accounts involves credit charges, which can range from 0.5 to 6 credits per use. If you need additional credits, you can purchase credit top-ups at a 50% premium over your plan's typical credit cost.
