cotomi v3
cotomi v3 is NEC's commercial language-model generation announced in July 2025. It supports longer Japanese documents and improves task decomposition and tool selection for business agents.
A longer input can contain several related documents
NEC gives 128K tokens as its long-input capacity. This is an input statement, not a separately published maximum output allowance. The same technical account describes improved selection of tools for smaller steps within a larger task.NEC technical account of cotomi v3 and agent systems
The appliance includes a separately licensed model
The June 2026 appliance guide lists the cotomi model separately from Generative AI FW V2.2, hardware and support. A server purchase alone does not describe the full software entitlement.June 2026 cotomi appliance configuration guide
Review the complete business workflow
Practical guidance. Use a representative document set with exceptions, tables and missing information. Check whether the answer uses the right document, then review tool arguments separately. A fluent Japanese answer does not establish that an external action is correct.
