Seed 2.0 Code

by ByteDance

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.

Uptime and availability

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.

100%route uptime, last 30 days

Its other routes aren't measured here yet.

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.
