What LLM aggregators do
An LLM aggregator gives access to several large language models through a single front door. Some are chat apps: one interface, one login and often one subscription that covers models from different labs. Others are API gateways: one key and one base URL that route requests to many providers, usually in an OpenAI-style format. A third group does not route anything and instead catalogs prices, speed and security so the choice can be made before any money is spent.
They are built for two audiences. People who chat with AI daily use the app type to avoid paying for and juggling separate accounts. Developers and teams use the gateway type to switch models without rewriting integrations, and to keep billing in one place.
How to choose one
Start with the interface you need. If the goal is conversation, look for a chat product; if the goal is to call models from code, look for an API with an OpenAI-compatible endpoint.
Then check the model list against your needs. Some tools cover text only, while others add images, video, music or PDFs. Counts vary widely, from ten models in a subscription to several hundred behind an API.
Pricing structure matters next. Flat subscriptions suit steady daily use, while pay-per-token or pay-per-use billing suits irregular or high-volume work. Features such as automatic failover, smart routing and caching matter for production workloads. Finally, consider the platform: most tools here are web apps, a few add desktop clients, and one is iOS only.

Common questions
What is an LLM aggregator?
It is a service that connects you to many language models through one interface, account or API. Instead of signing up with each provider, you use a single product and pick the model per task, or let the tool choose.
Should I pick a chat app or an API gateway?
A chat app fits people who want to talk to several models and compare answers. A gateway fits developers who need models inside their own software and want one key and one bill. Some tools combine both ideas, so check the listing for what is actually offered.
How do I compare costs before choosing?
Token prices differ by provider and are quoted in different units. A catalog such as TokenPricing normalizes them to dollars per million tokens, which makes side-by-side comparison straightforward. Subscription products are easier to judge by what the plan includes.
When to look elsewhere
If you want a plain assistant from a single provider without model switching, AI Chat Bot is the closer fit. For a simple, direct conversation with a model and no extra layers, Direct Chat AI is worth a look.
