Open-source Python SDK and AI gateway for calling 100+ LLMs through a unified OpenAI-compatible interface

oumiopen-source

Easily fine-tune, evaluate and deploy gpt-oss, Qwen3, DeepSeek-R1, or any open source LLM / VLM!

+Comprehensive end-to-end pipeline covering fine-tuning, evaluation, and deployment of open-source LLMs/VLMs with minimal setup
+Strong community support and active development with regular releases, extensive documentation, and integration with popular ML frameworks
+Advanced features including automated hyperparameter tuning, data synthesis, and RLVF support for sophisticated model training workflows

-Limited to open-source models only, excluding proprietary models like GPT-4 or Claude
-Requires significant computational resources and GPU access for effective model fine-tuning
-Learning curve may be steep for users new to LLM fine-tuning concepts and workflows
