Morph V3 Large: pricing, context and benchmarks

What you need to know about Morph V3 Large

Morph V3 Large was released by Morph (United States) on July 7, 2025. It accepts text as input and produces text. Its context window reaches 262,144 tokens, larger than 58 % of the models in the registry, and it can write up to 131,072 tokens in one go.

It has been available for about 16 months, long enough for its prices and scores to have settled.

Morph V3 Large pricing

On OpenRouter, Morph V3 Large costs $0.9 per million input tokens and $1.9 per million output tokens. Counting three tokens read for every token written, its average price is $1.15 per million, more expensive than 62 % of paid models (1.5 times the median of $0.76).

A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0028. At 1,000 tasks a day, budget $83 a month. The price calculator redoes this with your own volumes.

Epoch AI does not yet publish a capabilities index for Morph V3 Large. We therefore show no made-up performance rating: only price, context and features count towards its score.

Features, privacy and local use

• It does not support tool calling: it is not suited to driving an AI agent that has to act.
• It can answer in an enforced JSON format (structured outputs).

Its weights are not published: it can only be used through the Morph API or a broker such as OpenRouter, which means sending your data off your machines.
