Pros	Drop-in OpenAI-compatible proxy makes data capture trivial Meaningful cost/latency wins vs. frontier models on narrow tasks Now backed by CoreWeave GPU capacity post-acquisition Handles the full pipeline from logs to hosted fine-tuned inference RL-for-agents product targets multi-step tool-using workflows	Real, measurable 2-5x speedups and big VRAM savings on consumer GPUs Open-source core with permissive license and active GitHub Drop-in compatible with Hugging Face TRL, PEFT and transformers Excellent ready-to-run Colab notebooks for most popular models Exports cleanly to GGUF/llama.cpp, vLLM and Ollama
Cons	Not open source; you depend on their managed platform Only worth it once you have real production LLM spend to distill Post-acquisition roadmap tilts toward enterprise infra customers	Multi-GPU and multi-node are gated behind paid tiers with opaque pricing Not a hosted service — you still bring your own GPU and MLOps Cutting-edge model support sometimes lags official releases by days
