We now have the DeepSeek-R1-Distill-Qwen-32B model on Cloudflare Workers AI! Use it to solve math, coding and complex reasoning tasks. It's open source, hosted on Cloudflare servers, and is comparable to OpenAI's o1-mini.
What makes it shine:
🌟 It solves math, coding and complex reasoning tasks
🌟 It thinks out loud – watch its step-by-step logic!
🌟 Self-checks answers before responding
