Build Agents That Act
---

Web Search

### Autonomous Retrieval

Seed 1.8 model performs real-time web searches and integrates results into reasoning chains.

Code Execution

### Iterative Coding

Seed 1.8 API generates, debugs, and executes code within a unified agentic interface.

GUI Interaction

### Visual Task Handling

Seed 1.8 LLM interprets GUIs, charts, and videos for multi-step task execution.

Copy any prompt below and try it yourself in the [playground](/models/byteplus/seed-1.8).

Plan Itinerary

“Search current flights from New York to London next week, compare prices under $800, book cheapest option with good reviews, output JSON itinerary.”

Debug Script

“Analyze this Python code for errors: \[insert buggy code\]. Fix issues, execute test case with sample data, return corrected version and output.”

GUI Navigation

“Given screenshot of banking app \[describe image\], transfer $100 to savings account, confirm balance update, handle any prompts.”

Video Analysis

“Use VideoCut tool on this clip \[video input\], replay frames 10-20 at 3 FPS, identify objects and actions, summarize events.”

For Developers

A few lines of code.
Agents. One call.
