Kat Coder Pro is an agentic coding model from Kuaishou's Kwaipilot team, built for real-world software engineering tasks such as feature implementation, bug fixing, and refactoring. It pairs a 256K token context window with up to 128K output tokens, so it can work across large files and multi-step projects in a single session. The model reaches a 73.4% solve rate on SWE-Bench Verified, a benchmark that measures how often a model resolves real software issues. It was trained through a multi-stage pipeline that combines mid-training, supervised fine-tuning, reinforcement fine-tuning, and large-scale agentic reinforcement learning. Kat Coder Pro is tuned for tool use and multi-tool parallel invocation, multi-turn interaction, and instruction following across many programming scenarios. It is a text-only, non-reasoning model, returning direct responses without chain-of-thought overhead, which suits coding agents and automated engineering pipelines that need fast completions.
Kat Coder Pro runs on 1 route through the Opper gateway. Compare residency, ZDR, and training posture at a glance — full data-handling detail per route below.

Kat Coder Pro runs on a single route through the Opper gateway today, so its availability is that provider's availability.
Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider Opper monitors.
Each route hosting Kat Coder Pro has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
Zero data retention is available via Opper Enterprise contract. No training on customer data. US; SCCs; DPA available.
Call Kat Coder Pro through the Opper gateway with one API key. Let your coding agent set it up, or call it directly — Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.
Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up Opper for you.
import OpenAI from "openai";const client = new OpenAI({apiKey: process.env.OPPER_API_KEY,baseURL: "https://api.opper.ai/v3/compat",});const completion = await client.chat.completions.create({model: "novita/kwaipilot/kat-coder-pro",messages: [{ role: "user", content: "Hello" }],});console.log(completion.choices[0].message.content);
