Strengths	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Largest open-source AI model hub Hosted inference via Spaces + Inference Endpoints Great community
Weaknesses	Open-weight models only (no Claude/GPT) Less flexibility on custom configs	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Developer-only You build the UI	Overwhelming for beginners Hosted inference pricing varies
