Rocinante 12B
VerifiedRocinante 12B offers capable text generation with extended context handling.
About Rocinante 12B
Rocinante 12B is structured as a 12 billion parameter language model focused exclusively on text. Its closed-weight design allows Thedrummer to maintain full control over updates and access. The architecture accommodates sequences up to 32768 tokens while remaining efficient for production use.
Strengths center on reliable handling of longer documents without requiring open weights. The text-only modality keeps the system streamlined for linguistic processing. This setup supports consistent output quality across varied prompts.
Typical usage includes document summarization, conversational interfaces, and content generation workflows. Organizations deploy it where proprietary control and extended context are priorities. Integration occurs in applications needing stable text-based AI without public model weights.

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: "thedrummer/rocinante-12b",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: thedrummer/rocinante-12b
