Seed 2.0 Code AI Model to update repositories, pull requests and tests
ByteDance Chat and reasoning models Upgrade to use bytedance-seed/seed-2.0-code
A product page for the ByteDance Seed 2.0 Code model, the Seed family’s coding SKU tuned for repository-scale changes and multi-file edits. It is for engineers and dev teams who need a multimodal model that reasons across long histories and large code trees.
What it can do
- Reads images and screenshots
- Searches the live web and cites sources
- Thinks step by step on hard questions
- Understands video input
What people use it for
Large refactor across a repo
Give the model a repository snapshot and a short spec; it proposes minimal-change edits, updates imports and adjusts tests so the codebase stays runnable. Use the long context window to include multiple files and CI logs so changes remain consistent across modules.
Review and fix pull requests
Paste a pull request diff and failing test output; the model explains the root cause, suggests edits and provides a patched diff for easy application. It can generate commit messages and a concise reviewer summary to speed merge decisions.
Generate tests and documentation
From existing modules, the model writes unit tests, integration checks and API doc sections that match project style. Include sample inputs, stack traces or screenshots to produce targeted tests and runnable examples.
Why it is worth it
- Handles multimodal inputs: code, images and short videos for UI or repro traces.
- Supports very long context so multiple files, logs and issue threads can be considered together.
- Produces concise patch diffs and suggested commit messages ready to apply.
- Explains nontrivial failures with step-by-step troubleshooting and test suggestions.
Questions people ask
How is Seed 2.0 Code different from general-purpose Seed models?
Seed 2.0 Code is a dedicated coding SKU in the Seed 2.0 family, tuned for agentic coding and repository-scale edits; it focuses on code generation, refactoring and multi-file reasoning rather than general chat or search tasks.
What inputs can I provide and how large can the context be?
The model accepts text, images and video as prompts and supports a very large context window suitable for multi-file repositories and long histories. Published model materials note the multimodal inputs and extended context capacities.
How is usage billed on Katteb?
On Katteb this model costs 7 credits per message; billing is per-message on actual usage in credits. You can switch models mid-conversation and compare results side by side in the Katteb chat interface.
