What is Groq?
Groq is an AI inference platform famous for one thing above all: speed. Powered by its own custom hardware — the Language Processing Unit (LPU) — Groq runs popular open large language models at remarkably high speeds and low latency, often generating responses far faster than conventional GPU-based services. For developers building AI applications where responsiveness matters, this near-instant inference is a genuine game-changer.
The reason Groq is so fast comes down to its purpose-built chips, designed specifically for the sequential nature of language model inference rather than repurposed from graphics workloads. The result is throughput and latency that make real-time AI experiences feel truly real-time — chatbots that respond the instant you finish typing, voice agents with minimal lag, and agentic systems that chain many model calls without slowing to a crawl. Speed isn't just a nicety here; it unlocks use cases that feel sluggish or impractical on slower infrastructure.
Groq offers access to a range of leading open models through a simple, fast API (and a cloud console), making it easy for developers to switch from slower providers and immediately feel the difference. Because it focuses on inference of open models, it appeals to teams that want high performance and predictable, competitive pricing without being locked into a single closed model vendor. For applications like conversational AI, real-time assistants, voice interfaces and high-volume agentic workflows — anywhere latency directly shapes the user experience — Groq has become a standout choice. It represents a hardware-led approach to the AI boom, betting that as models become commoditized, the speed and efficiency of running them will be a decisive advantage. For developers chasing fast, responsive AI, Groq delivers.
What is UnoRouter?
UnoRouter is an open-source LLM gateway for developers and teams comparing OpenRouter alternatives who want one bill, one key and full visibility into how their AI requests are routed.
The problem it solves
Most products that use AI end up talking to several labs. One feature runs on GPT, another on Claude, a third on Gemini or an open model like DeepSeek or Qwen. Each provider brings its own account, API key, SDK quirks, rate limits and invoice, and each one can go down at the worst moment. UnoRouter puts all of that behind a single OpenAI-compatible endpoint, so you integrate once and choose the model by name.
How it works
Point any OpenAI SDK, or any tool that accepts a custom base URL, at UnoRouter and use your UnoRouter key. Requests are routed to a healthy upstream provider. If that provider returns errors, rate limits you or times out, the call is retried on another provider automatically, which keeps chat features and agents running through upstream incidents. Streaming and tool calls come back in the familiar OpenAI format.
Who it is for
Developers building AI features into SaaS products, people using coding agents such as Claude Code, Cline or OpenCode who want to switch models freely, and anyone who prefers one dashboard with per key and per model usage over a stack of provider consoles. It also suits small teams that want to try a new model the day it ships without signing another contract.
How it compares
Unlike closed routers, the whole UnoRouter stack is open source on GitHub: the storefront, the backend, the gateway and the tooling that syncs and tests providers. The built-in web chat is local-first, so conversations are stored in your browser instead of on a server.
Pricing
There is a free tier with free models that needs no credit card. Paid models are pay-as-you-go from prepaid credit, with no subscription and no monthly minimum.
What problem it solves
Teams that use several AI labs end up juggling separate keys, SDKs, invoices and outages. UnoRouter replaces that with one OpenAI-compatible key and automatic failover between providers.
Alternatives & competitors
An open-source alternative to OpenRouter, Portkey and LiteLLM style gateways, with local-first chat and a free tier that needs no card.
