Free Models Router
VerifiedRoutes prompts to free multimodal models with 200k context.
About Free Models Router
Designed as an intelligent dispatcher, Free Models Router evaluates incoming queries and matches them to suitable free models hosted through the OpenRouter platform. It abstracts away model selection so developers can focus on application logic rather than availability checks. The service remains closed-weight and does not expose underlying parameter counts.
Its primary strength lies in combining broad multimodal support with an unusually large context window, allowing extended image-plus-text conversations without truncation. Because it draws only from free tiers, output quality can vary by current model availability. Typical usage includes prototyping, educational experiments, and low-volume production workloads where cost is the dominant constraint.
Capabilities
Best for
Long document summarization and analysis
Routes requests to free models capable of handling up to 200k tokens for detailed text generation and analysis of extensive inputs.
Image captioning and visual reasoning
Processes image inputs alongside text to deliver descriptions and multimodal understanding in a single conversational flow.
Zero-cost model experimentation
Automatically routes queries across available free models to support text, image, and conversational tasks without requiring paid endpoints.
Strengths & limitations
Strengths
- +Free access to multiple models
- +Large context window support

Limitations
- –Performance depends on routed model
- –Variable output quality and speed
- –Potential routing delays or limits
Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "openrouter/free",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openrouter/free

At no token cost, it is free to run for its class.
It is available through Openrouter's API and aggregators like OpenRouter.
Best suited to free access to multiple models and large context window support.
