Keln Reviews & Product Details

Keln is a reliability layer for open-weight language models such as DeepSeek, Kimi, Qwen, GLM and gpt-oss. Built for teams that run open models in production. You call one OpenAI-compatible endpoint at one published price per model, and Keln routes each request across a pool of GPU providers that it verifies continuously. Slow routes are raced and billed once, a stream that dies part way continues on another node, and nodes serving degraded output are removed until they pass again. Keln also accepts the Anthropic Messages format, so switching from OpenAI or OpenRouter means changing the base URL and the key. Prompts and completions are never stored or used for training. Live prices are at keln.ai/models.
