💬 Discussion 5 — Why Did TGI Lose Its Edge? (20 pts)

Hugging Face's Text Generation Inference had a multi-year head start and the backing of the most prominent open-source AI company in the industry — yet it was moved into maintenance mode in late 2025 while vLLM and SGLang continued to gain adoption. Post a response addressing:

- Why do you think Hugging Face made the decision to put TGI into maintenance mode despite its historical market position?
- What does this decision signal about the competitive dynamics of open-source serving engines — is being first to market enough to stay relevant?
- Name one specific technical capability (from this week's material) that you think tipped the balance toward SGLang or vLLM, and explain why it mattered.

Then respond to at least two classmates, engaging with a point in their post you agree or disagree with and explaining why.
