deepseek-r1-0528 — Free API

What is deepseek-r1-0528?

DeepSeek R1 (0528 checkpoint) is available free through LLM7.io, a community proxy that provides OpenAI-compatible API access to popular models. R1's chain-of-thought reasoning makes it strong at math, competitive programming, and logic puzzles — the 0528 variant is a specific checkpoint release. As a shared community proxy, rate limits and availability are not guaranteed; best used for personal evaluation and low-volume testing rather than production workloads. No credit card required, but stability expectations should be calibrated accordingly.
