Seed 2.0 Code is ByteDance's coding-specialized variant in the Seed 2.0 family, taking the Seed 2.0 foundation and tuning it for software engineering workflows including code generation, debugging, pull request review, and codebase navigation. It is built to slot into developer toolchains and autonomous coding agents. The model produces clean, well-formatted code with fewer extraneous explanations, which makes it suited to integration into editors, CI pipelines, and agent-driven development loops. It supports a 256k context window with thinking modes, giving it room to reason through complex architectural changes and multi-file refactoring tasks. Within the Seed 2.0 lineup, Code targets high-volume engineering scenarios where coding throughput matters most, from large-scale code assistance to agent-based development. It pairs strong instruction following with structured tool use for executing edits and tests across a project.
Seed 2.0 Code runs on 2 different routes through the Opper gateway. Compare residency, ZDR, and training posture at a glance — full data-handling detail per route below.
One of Seed 2.0 Code's 2 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.
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. 1 further route is not on the board yet. See uptime for every provider Opper monitors.
Each route hosting Seed 2.0 Code 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. GLOBAL; SCCs; DPA available.

Call Seed 2.0 Code 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: "bytedance:ap/seed-2.0-code",messages: [{ role: "user", content: "Hello" }],});console.log(completion.choices[0].message.content);
