Build with GPT-6 Astra. Launch on Product Hunt on September 18. We've teamed up with @OpenAIDevs for the GPT-6 Astra Challenge. The top five launches each win $10K in OpenAI API credits and a year of ChatGPT Pro for up to two team members. If you’re already building with Astra, this is a chance to share what you’ve made and put it in front of a wider audience. You can schedule your launch for Friday, September 18.
