About

OpenRouter is an AI model routing platform that gives developers access to hundreds of models through a single unified API. It connects users with models from providers such as OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Qwen, xAI, and many others. The platform supports text, image, video, and audio generation while allowing developers to use one API key and a consistent interface across providers. OpenRouter can route requests based on price, performance, and availability, with fallback options that help maintain service when a provider experiences downtime. It also offers configurable data policies so organizations can control which providers receive prompts and how requests are handled. Developers can purchase credits, choose from more than 500 active models across over 80 providers, and integrate OpenRouter using an OpenAI-compatible API.

About

Tev1 is a fast decision and classification model built by Together AI and fine-tuned from Qwen3.5 4B. It is designed around a simple interface: provide a piece of state, a question, and 2 to 24 labeled options, and the model returns exactly one letter that software can map back to a semantic key. This structure supports production tasks such as routing support tickets, evaluating automated returns, applying policy rules, rating sentiment, categorizing documents, and inserting deterministic decision points into larger agent pipelines. The model has 4.7B parameters, a 32.8K-token context window, and runs with non-thinking generation for fast, predictable classification. It was trained on 37,840 examples spanning intent detection, boolean comprehension, sentiment, policy application, routing, news categories, and research-paper taxonomy. Recommended settings use temperature 0 and a very small output budget so responses remain stable and easy to parse.

Pros & Cons from Real Users

Pros

  • Instead of getting married to ChatGPT or Claude and being locked into that relationship, OpenRouter is way more polyamorous. LMAO. And it's less messy than the real life relationship version. I can use different LLMs for different types of tasks and you learn quickly which LLMs excel in certain areas. In the beginning I did multichats where I'd ask 1 question to 2 or 3 bots at a time (their multichat features) and whoever gave the best answer was who I continued interacting with. I guess it's more like speed dating than polyamory. But the bottom line is, instead of spending $20-$30/mo with one system, I am spending a la carte, which is WAAAAYYYY cheaper, and using the right tool at any given moment. It just takes discipline to copy and paste your chats elsewhere. It does give you a copy markdown button to make it easier. And if you enable markdown in Google docs, there is a paste as markdown feature that makes it look like RTF when it's pasted in, with no codes. Because the chats are browser bound, they are stuck on one computer and everybody is on a bunch of different devices these days. So pasting into Google Docs is the best bet for portability all around. Privacy isn't an issue, because they aren't storing your chats! For some people, this is a big plus. To use the service, they charge you a 9 or 10% charge for however much money you put towards tokens. So if I refill for $10, the total is $10.90, with $10 of usable token for whichever LLM I feel like using. Keep in mind, there are free LLMs too which you can choose and never pay. When you add models, type 'free' in the search box and you'll see several free, from Maverick to Scout to Gemma, etc. It will make you feel like a serious power user and you'll feel smarter everytime you use it. It also has access to the secret parameters that the online LLMs don't show you, like Temperature, Top P, Frequency penalty, etc. It can save you money if you tell it ahead of time what type of vocab you like or how divergent you want the suggestions to be, vs. training ChatGPT or Gemini manually.

Cons

  • The chats aren't persistent - you must copy and save them elsewhere before you close a browser window, or all that info from that chat is gone.
