TensorZero archived its repo days after a $7.3M seed became public.
Story
TensorZero, an open-source LLMOps platform unifying gateway, observability, evaluation, and optimization, used by companies up to the Fortune 10, went read-only on GitHub June 12 (Hacker News). The CEO's HN post (269 points) said that despite raising $7.3M in 2024, they're winding it down. The thread became the week's referendum on whether open-source infra companies can survive on seed funding. My read: the gateway/observability layer is brutal because the model vendors keep absorbing it into their own SDKs. Hard to sell the plumbing when Anthropic and OpenAI ship it free.
