Powering Your Code: A Guide to Syncoo's AI Models

Building real-world software takes more than a simple prompt-and-chat interface. Syncoo turns multi-modal context—including visual mockups, documentation links, architectural specifications, and multi-file workflows—into production-ready features. To give you complete flexibility over performance, depth, and cost, Syncoo supports three distinct LLMs:

Supported AI Models At-a-Glance

  • DeepSeek Flash (Default) — high-speed sub-second execution for everyday code editing, quick iterations, and UX tweaks.
  • DeepSeek V4 Pro — heavy-duty reasoning for multi-file refactoring, complex backend logic, and system architecture.
  • Claude Sonnet 4.6 — frontier multi-modal for pixel-perfect UI translation, long-horizon agentic execution, and spec compliance.

DeepSeek Flash (Default Model)

DeepSeek
Context: 1,000,000 Tokens

DeepSeek Flash is the default engine in Syncoo, optimized specifically for fast, responsive execution.

Best for: Instant UI builds, real-time code completion, iterative feedback loops, and daily task execution.

When to use: Keep Syncoo on DeepSeek Flash for everyday feature implementation, layout adjustments, and quick iterative refactoring.

Why it's the default:
