Hey Product Hunt 👋 We built flatkey because our own AI bill had turned into a mess. We had one account for Claude, another for GPT, more for Kimi, DeepSeek and GLM, plus a video model on top. Each had its own key, top-up, invoice and rate limits. Most of our time went to managing accounts instead of building. flatkey is one key and one bill for all of them. • One key, one bill: Claude, GPT, Kimi, DeepSeek, GLM, Seedance and more on a single balance. • Affordable: most LLMs are 20% off official pricing. • Same quality: you get the same output as calling the official models, and 10,000+ customers have tested that. • Easy to switch: change base_url to router.flatkey.ai/v1 in the OpenAI SDK. You can also use the flatkey CLI, or plug it into Codex and Claude Code. • All modalities: text, image, video and audio. • Secure: SOC 2. One example: VOC.ai has analyzed 1B+ Amazon reviews with ChatGPT. They moved that workload to flatkey and cut their model costs by 40%. We'd love your feedback: which model should we add next, and what does your AI bill look like today? We'll be here all day answering questions.
