Groq
Groq runs open models on custom silicon it designed, called the LPU, to deliver some of the fastest inference available. Instead of building its own models, it serves open weights such as Llama, Qwen, Whisper, and OpenAI's open releases, often at well over five hundred tokens per second, which makes a real difference for voice agents, chat, and any workflow where responsiveness matters. GroqCloud exposes this through an API with a free tier for developers and low per-token pricing that undercuts many competitors. Founded by former Google chip engineers, Groq raised at a multibillion-dollar valuation and serves over two million developers; in 2026 NVIDIA licensed its inference architecture in a major deal, while Groq continues to run GroqCloud independently. The trade-off is model choice: you're limited to the open models Groq hosts, not the full closed-model lineup.

Our take
Groq serves open models on its custom LPU silicon at 500+ tokens per second, among the fastest inference anywhere, through GroqCloud's API with a free tier and low per-token pricing. Great for latency-sensitive agents and chat. The catch is you're limited to the open models Groq hosts, not closed frontier models.
Best for
Developers building latency-sensitive apps - voice agents, real-time chat - who want the fastest inference on open models at low cost.
Pros
- Custom LPU silicon delivers 500+ tokens per second
- Free developer tier and low per-token pricing
- Serves popular open models like Llama, Qwen, and Whisper
- 2M+ developers; NVIDIA licensed the architecture
Cons
- Limited to the open models Groq hosts
- No proprietary frontier models
- Heavy demand can mean rate limits on the free tier
How it compares
Groq competes with Together and Fireworks on open-model inference, but differentiates on raw speed through purpose-built hardware rather than GPU optimization.

NotebookLM
Google's source-grounded research assistant: upload docs, PDFs and links, then ask questions, generate study guides, and turn sources into audio and video overviews. The free tier is genuinely usable; Plus raises the limits.
OpenRouter
OpenRouter is a unified API and marketplace for large language models. With one account and key you can reach 300+ models from OpenAI, Anthropic, Google, Meta, Mistral, Cohere and many smaller providers, using an OpenAI-compatible interface. It charges passthrough rates (provider cost plus a small markup) and publishes live pricing and usage-based model rankings, so you can compare options and route to the cheapest, fastest or most reliable one. It supports automatic fallback across providers and a free-model tier for experimentation; the main costs to watch are a 5.5% credit-card fee, which hits small top-ups hardest, and a 5% bring-your-own-key fee on requests above one million per month.
