SDK Overview

The Atelico AI Engine exposes its capabilities through platform-specific SDKs that follow each engine's native conventions. All SDKs share the same underlying Rust core and provide the same capabilities.

Architecture

                    atelico-sdk (Rust Core)
                   /           |              \
          gdext (Godot)    C ABI (FFI)     PyO3 (Python)
                          /         \
                    Unity C#    Unreal C++

• Godot and Python bind directly to Rust (zero-overhead)
• Unity, Unreal, and raw C/C++ go through the C FFI layer

Capabilities

All SDKs expose the same capabilities:

Capability	Description
LLM Chat	Streaming and non-streaming text generation
Image Generation	PixArt and Sana image generation
Embeddings	Text embeddings with BERT models
Classifiers	Embedding-based text classification
LoRA	Runtime LoRA adapter loading/unloading
Structured Generation	JSON Schema-constrained output
Prefix Cache	Reuse prompt KV state across requests; fork/release prefixes for dialogue branching
Answer Cache	Cache full prompt → completion results with TTL, LRU, and adapter/namespace isolation
Matcher	Pluggable embedding / LM-choice / cascading matchers for option selection
GPU Scheduling	CiG integration for GPU sharing with renderer

Available SDKs

• Godot -- GDExtension, GDScript-native signals and async
• Unity -- C# UPM package with async/await and delegates
• Unreal Engine -- Plugin with Blueprints and C++ API
• Python -- Native module with async iterators
• C FFI -- Raw C ABI for custom integrations
