Mato v1.0: our own model that operates your tools, now published in the open

Context

In NapsixB2B the work is done by XIA, and behind XIA there is a model that decides which tool to use, in what order and with which data. That model is now ours: Mato v1.0. Mato v1.0 was trained on Alibaba Cloud's Qwen family (Qwen 3.8 27B base, Apache-2.0 license, official FP8 quantization) and is now published openly on Hugging Face: anyone can view it, accept the terms and clone it to build on top. Want the full experience? Our infrastructure serves it free over the API.

What changes

  • Verified tool-calling on Napsix tools. Mato doesn't *mention
  • your apps: it operates them. It reads and writes spreadsheets, searches and updates contacts and deals in the CRM, reads mail threads, crawls the web and drafts documents.
  • 26 native apps and 24 chat commands available from the first message, with no connectors to build and no keys to configure.
  • It plans before it executes. It picks the tools it needs and the order to use them before touching anything, then delivers the artifact ready to review: the sheet, the contact, the report.
  • Long context: 256k native tokens, extendable to 1M with rope scaling. Flexible thinking, on by default in direct mode.

Production performance

  • ~2s for short answers
  • ~30 tok/s streaming
  • 580k KV cache tokens
  • 17.7× concurrency

Measured on Daytona H100; varies with load.

What it means for you

  • Zero cost per task. Mato is served at $0 per token on every plan. Combined with routing each task to the right-sized model, every job can go to the cheapest engine that solves it well.
  • Less integration surface. Where a generic model needs connectors someone has to build and maintain, Mato goes through the system's native tools: Gmail, Sheets, HubSpot and the rest of your integrations.
  • No lock-in. Apache-2.0 license and open weights: you can audit the model and, if your data policy requires it, clone it and self-host.

What we're doing

Two versions are already in training: Mato 1M, with 1M tokens of context to fit whole projects, repos and datasets into a single conversation, and Mato Flash 1M, the fast variant with the same context, built for volume, classification and parallel agents. In the meantime, Mato v1.0 is live: try it free over the API or clone it from Hugging Face.
