About Morph V3 Large
Morph V3 Large is a closed-weight LLM developed by Morph for text modality tasks. It features a context window of 262144 tokens and is not available as open weights. The design focuses on delivering consistent performance for lengthy textual inputs.
Its primary strength lies in accommodating very large context sizes that support detailed document handling. Because it remains proprietary, access occurs through Morph's platform rather than local deployment. This setup ensures controlled updates and optimized inference.
Typical usage includes enterprise applications such as long-form content creation, multi-turn dialogue systems, and analysis of extended documents. Teams integrate the model where maintaining coherence across substantial text volumes is essential.

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: "morph/morph-v3-large",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: morph/morph-v3-large
