Top Use Cases

IDE Autocomplete

Powering real-time code suggestions as you type.

Example: “<FIM_PREFIX>async function fetchData() {<FIM_SUFFIX>”

Detailed Features

80+ Programming Languages: Native-level support for Python, JS, C++, Rust, Go, and more.

32K Context Window: Large enough to review multiple modules and project structure.

Fill-In-the-Middle (FIM): Specialized training for real-time autocomplete and code insertion.

Optimized Latency: Designed to power local and cloud-based IDE extensions with instant feedback.

Architectural Depth: Strong performance in identifying logical bugs and suggesting refactors.

Open Weights (Non-commercial): Available for research and personal use by developers.

✓ Strengths & Pros
