Netflix Headroom: How to Cut AI Agent Costs 10x in Production [2026]
The LLMOps tooling ecosystem is fragile. Case in point: TensorZero, an open-source inference optimization tool, was archived shortly after raising a $7.3M seed round. That's $7.3M that evaporated. When you build your cost optimization stack on tools from early-stage startups, you accept the risk that the tool disappears out from under you.

AI OSS tool repo goes archived over night after raising $7.3M Seed

AI Gateways in 2026: a field guide to the 106 cost problem
Self-hosted, your infrastructure. Your keys, your network, no per-token middleman fee — you pay only for the box it runs on. LiteLLM is the broad default (Python, 100+ providers, virtual keys and budgets). If the gateway must never be your bottleneck, Bifrost (Go) and TensorZero (Rust) are built for throughput. If you already run Kubernetes, the AI plugins on Kong, Higress or Apache APISIX mean one less new service to operate.

Supervised Fine Tuning on Curated Data Is Reinforcement Learning
[I'm his coworker.] We ran Unsloth ourselves on a GPU-by-the-hour server. We have a notebook in the repository showing how to query historical data and use it with Unsloth.
It's a WIP PR that we plan to merge soon: https://github.com/tensorzero/tensorzero/pull/2273
