Show HN: JTC – JSON/YAML Type Checker Using TypeScript

Hacker News - Tue, 03/10/2026 - 2:22am

If you add a $schema field to JSON or YAML, you can run JSON Schema validation. Likewise, if you add a $type field, this tool performs TypeScript-based checks.

It provides both a VSCode extension and a CLI.

The VSCode extension offers Diagnostics (it draws a red underline when something is wrong) and a Go To Definition feature. Since it’s published on both the Marketplace and open-vsx, the extension can also be used in other VSCode-based editors such as Cursor.

The CLI provides check and lsp commands. With the check command, you can run JSON type checks in CI/CD, and with the lsp command, it can be integrated and used in editors other than VSCode.

I’m planning to soon implement type-based field auto-completion and a feature that shows documentation on mouse hover. I’m also considering adding type checking using other static type languages besides TypeScript.

Calling all who run inference in models

Hacker News - Tue, 03/10/2026 - 2:20am

We've been thinking a lot about inference infrastructure recently, and it seems like the challenges are very different from training. Training tends to be compute-heavy but predictable, while inference introduces things like: - latency constraints - dynamic batching - unpredictable traffic patterns - model versioning in production - GPU utilization issues at smaller batch sizes For people running inference in production today, what's been the most painful part?

Branching prompts instead of linear chat

Hacker News - Tue, 03/10/2026 - 2:20am

Most LLM interfaces assume thinking happens in a straight line.

prompt → response → refine → refine

But when I explore ideas with AI, it usually branches.

One prompt leads to multiple directions, and it's hard to compare them in a single chat thread.

So I built a small workspace where prompts branch like a tree.

You can explore different reasoning paths and continue from the most interesting one.

I'm curious what HN thinks about node-based interfaces for prompting compared to traditional chat UIs.

How are people do AI evals these days?

Hacker News - Tue, 03/10/2026 - 2:11am

With the buzz that's happening with all the new AI models that get released (what feels like every other week), how are companies running internal AI evals to determine which model is best for their use case?
