Inference Providers Hub

One API, 10+ cloud backends — model inference without the chaos

Hugging Face's Inference Providers Hub is a unified API layer that routes model inference requests across 10+ cloud backends — including AWS Bedrock, Fireworks AI, and Together AI — using a single authentication token. It supports automatic fallback routing, so if one provider is down or throttling, requests seamlessly shift to another. Developers can swap inference backends without rewriting integration code, dramatically reducing vendor lock-in.

AI agent that diagnoses why your LLM app failed in production

Kelet is a production monitoring platform that automatically diagnoses and fixes failures in LLM applications and AI agents. Rather than requiring engineers to manually sift through thousands of traces, Kelet reads production agent traces, clusters failure patterns across sessions, and surfaces root causes with supporting evidence. The platform's standout feature is credit assignment for multi-agent architectures — when a LangChain, CrewAI, or PydanticAI pipeline fails, Kelet pinpoints exactly which agent in the chain caused the failure rather than returning a vague error message. It then generates targeted prompt patches with measurable before/after reliability improvements, so fixes ship with proof they work. Setup takes approximately five minutes via the Kelet SDK or installer skill, with full OpenTelemetry compliance for teams already running observability infrastructure. Kelet covers the LLM token costs for its own analysis, and a free tier requires no credit card — making it accessible to indie builders before they've committed to paid tooling.

This is genuinely the multi-cloud inference abstraction layer I've been hacking together myself for two years — now it just exists. Single auth token, automatic fallback, and no rewrite when a provider changes pricing or goes down? Ship it immediately. The only caveat is that provider-specific features like fine-tuned model routing may still need manual handling.

Kelet solves the specific hell of debugging AI agents in production: thousands of traces, failure patterns scattered across sessions, and no clear signal about which prompt, which agent, or which data caused the issue. The credit assignment for multi-agent chains is the killer feature — knowing exactly which subagent in a CrewAI or LangGraph chain broke is worth the integration cost alone. Five-minute setup via SDK and OpenTelemetry compliance means it plugs into what you're already running.

Abstraction layers sound great until they become the single point of failure between you and your production workload. I'd want ironclad SLA guarantees and crystal-clear latency overhead numbers before trusting this hub in anything mission-critical. Also, 'automatic fallback routing' is doing a lot of heavy lifting in that marketing copy — show me the fine print on how model version parity across providers is actually managed.

Kelet is an LLM analyzing LLM failures, which is a charming recursion problem. When your agent monitoring agent hallucinates a root cause, you've added a failure mode that's harder to debug than the original. The 'evidence-backed fixes with before/after reliability measurements' pitch sounds airtight, but those measurements depend on the LLM evaluation being correct — which is exactly what you can't assume in production. A solid structured logging + tracing setup with deterministic replay would catch most of these failures without adding another probabilistic layer.

This one is squarely in infrastructure territory — not much here for the design-and-content crowd unless you're building your own AI-powered app from scratch. If you're a solo creator who just wants to call a model API once in a while, the multi-provider routing complexity is overkill. Respect the engineering, but this isn't my lane.

80/100 · ship

For indie builders shipping AI products to paying customers, Kelet is exactly the kind of tooling that turns 'my agent sometimes fails and I don't know why' into a real support workflow. The free tier with no credit card means you can actually test whether it's useful before committing.

This is quietly one of the most important infrastructure moves in the AI ecosystem this year. A commoditized, provider-agnostic inference plane is what prevents any single cloud giant from locking up the model deployment layer — and that matters enormously for the long-term health of open AI development. Hugging Face is positioning itself as the neutral rail of the AI stack, and I think that bet pays off big.

80/100 · ship

Observability tooling for AI agents is a category that barely exists and desperately needs to. As agent deployments move from side projects to production infrastructure, teams need the same root cause analysis discipline that SRE culture built for traditional services. Kelet is early in a space that will be massive — expect DataDog, Grafana, and every APM vendor to build versions of this within 18 months.
