We built open OpenRouter that turns usage into a better model

Hi HN, we built an open source model gateway. It's a single place to manage our own self hosted, frontier, and open source models in one place. It’s is rust native, built for concurrency, and implements all the config quirks across models and providers (streaming formats, tool calls, model parameters, rate limits, and different error behavior). The gateway adds under 1 ms for BYOK requests and under 2 ms when Experiential supplies the provider key. It has every major inference provider, and 1000... (220 points, 46 comments).

Market Signal

Why It Has Market Pull

An open-source, Y Combinator-backed model gateway that gives teams a single control plane across closed, open-source, local, and custom LLMs, adding under 2ms of latency while continuously distilling cheaper, comparably capable models from real agent traffic.

  • Launched on Hacker News as a Show HN post that drew 220 points and 46 comments, a strong reception for infrastructure tooling.
  • Backed by Y Combinator as Experiential Labs, founded in 2026, focused on continual learning for agents.
  • 758+ GitHub stars with same-day commits; supports OpenAI-compatible and Anthropic Messages APIs with drop-in repointing for Claude Code, Cursor, Codex, and Aider.
  • Free bring-your-own-key pass-through for major providers, adding under 1ms latency for BYOK requests.
  • HN commenters raised substantive technical questions on caching economics and telemetry defaults, which the founders answered directly in-thread.

I built a tool showing how AI providers (should) throttle their models

6 pts

OP here: this project was born out of the frustration/paranoia that AI providers are throttling their models when their server load is too high. So, I set out to model and study the problem mathematically to understand what was happening, what I found was quite surprising. The idea seems natural: as the data center demand increases momentarily through the day, throttling their models (either using quantized versions, reducing the context window or lowering the tier of the model to a smaller one)...

Unified text-to-image and image editing model Text-to-image and image editing demo for sensenova/SenseNova-U1.5-8B-MoT, a natively unified multimodal model (18B params, bf16) built on the NEO-unify architecture.

Advanced options exposes denoising steps, guidance scale, timestep shift, image guidance (editing) and the seed.
