Running the same AI model on your phone, in your browser, on your server, and inside a game engine — without converting anything

A technical deep-dive for developers and a practical guide for everyone else on why local AI is about to get a lot more accessible

The Problem Everyone Has (But Nobody Talks About)

You’ve probably used ChatGPT. Maybe you’ve tried Claude or Gemini. They’re impressive, but they all share the same fundamental limitations:

  • They require internet (no WiFi on that flight? Too bad)
  • They cost money per use (every message = money to OpenAI/Google/Anthropic)
  • Your data goes to their servers (hope you trust them with your conversations)
  • They can change or disappear (remember when Twitter’s API got expensive overnight?)

For regular users, this means AI is something that happens “somewhere else” — in the cloud, controlled by big tech companies, requiring constant connectivity and trust.

For developers, it’s even worse. Try to build an app that uses AI, and you face:

  • Platform fragmentation: Different tools for web, mobile, desktop, embedded devices
  • Conversion hell: Convert your model to ONNX for this, TensorFlow Lite for that, CoreML for iOS
  • Inconsistent outputs: The same model produces slightly different results on different platforms
  • Dependency nightmares: Installing AI libraries means downloading gigabytes of software
  • Vendor lock-in: Build on OpenAI’s API? Good luck switching to something else later

What if there was a better way?

The Vision: AI That Works Everywhere, Identically

Imagine downloading an AI model once and running it:

  • On your Android phone (offline, in airplane mode)
  • In your web browser (no server needed)
  • On your laptop (Windows, Mac, or Linux)
  • Inside a video game (for intelligent NPCs)
  • On a Raspberry Pi (edge computing)
  • In a Python script, JavaScript app, or C# program

With identical behavior everywhere. Not “close enough.” Identical.

With zero format conversions. Just load and run.

With no cloud dependency. Everything local, private, under your control.

That’s LOOM. And it’s working right now.

What Is LOOM?

LOOM (Layered Omni-architecture Openfluke Machine) is a neural network framework written in Go that solves the fundamental problems of AI deployment.

For Non-Technical Readers:

Think of LOOM like a universal translator for AI models. Just as you can play an MP3 file on your phone, computer, or car stereo without converting it to different formats, LOOM lets the same AI model run on any device without modification.

Want to chat with an AI on your phone without sending your data to the cloud? LOOM does that.

Want a video game where NPCs can actually hold conversations? LOOM does that too.

Want to use AI in a medical app where patient data can’t leave the device? LOOM enables it.

For Technical Readers:

LOOM is a cross-platform ML runtime with several unique properties:

  • Native HuggingFace support: Loads safetensors directly, no conversion to ONNX/TFLITE/GGUF
  • Cross-platform determinism: Same model produces identical outputs (MAE < 1e-8) across all platforms
  • Universal API: Same function calls in Python, JavaScript, C#, Go, and WASM
  • Zero Python dependency: Pure Go core + C-ABI bindings = single binary deployment
  • Game engine native: First framework with native integration into Godot (and extensible to Unity/Unreal)
  • Published packages: Already on PyPI, npm, and NuGet

Technical architecture:

Why This Matters: Three Real-World Stories

Story 1: The Indie Game Developer

The problem: Sarah is building a story-rich RPG. She wants NPCs that can hold actual conversations, remember what players said, and respond contextually. But:

  • Unity ML-Agents requires a Python server (can’t ship that to players)
  • Cloud APIs cost money per conversation (impossible for indie budgets)
  • Most “AI NPCs” are just decision trees pretending to be smart

The LOOM solution: Sarah loads SmolLM2–360M directly into her Godot game via C-ABI. Now her NPCs can:

  • Generate unique dialogue based on game context
  • Remember past conversations (stored locally)
  • Work offline (no internet required)
  • Cost nothing per interaction (one-time model download)

Result: The first indie game with truly conversational NPCs, running entirely on players’ devices.

See it working: Godot + LOOM Demo

Story 2: The Healthcare Startup

The problem: Dr. Martinez’s team is building a medical note-taking assistant. But healthcare regulations are strict:

  • Patient data CANNOT go to cloud APIs (HIPAA violations = massive fines)
  • AI outputs must be reproducible for audits (regulatory requirement)
  • Must work in hospitals with restricted internet (many are air-gapped)

The LOOM solution: Deploy LOOM to doctors’ tablets and desktops. Same model, identical outputs on both platforms, everything stays local.

Technical win: MAE < 1e-8 across platforms means audit trails are provable. “This output came from this model with this input” is verifiable.

Result: AI-powered medical tools that comply with regulations and protect patient privacy.

Story 3: The Mobile App That Works Offline

The problem: You’re traveling internationally. Your flight has no WiFi. You want to:

  • Translate text
  • Get writing suggestions
  • Chat with an AI assistant
  • Generate ideas

But every AI app says “No internet connection.”

The LOOM solution: An Android app running SmolLM2–135M locally. Full conversational AI in your pocket. No internet required. No data leaving your device. No subscription fees.

See it working: Android Demo

The Technical Deep Dive: How Does It Actually Work?

Architecture Overview

LOOM is built on three core principles:

1. Universal Model Format

Instead of requiring conversion to platform-specific formats (ONNX, TFLite, CoreML, GGUF), LOOM loads HuggingFace’s native safetensors format directly.

# No conversion needed - just load
import welvet
welvet.Transformer.load_model("HuggingFaceTB/SmolLM2-360M-Instruct")
welvet.Transformer.generate("Once upon a time")

Why this matters: Every conversion introduces:

  • Potential bugs (ops that don’t translate cleanly)
  • Maintenance overhead (re-convert after every update)
  • Accuracy drift (subtle numerical differences)

LOOM eliminates all of this.

2. Cross-Platform Determinism

Most ML frameworks are “mostly reproducible” — outputs vary slightly between platforms due to:

  • Different math libraries (Intel MKL vs OpenBLAS vs Apple Accelerate)
  • GPU vendor differences (NVIDIA cuDNN vs AMD ROCm)
  • Floating point implementation details
  • Compiler optimizations

LOOM achieves bit-exact determinism (MAE < 1e-8) by:

  • Pure Go implementation with explicit math operations
  • Fixed-precision arithmetic where needed
  • Deterministic layer implementations
  • Comprehensive cross-platform testing

Validation example:

Platform | Output Hash | MAE vs Reference
--------------|--------------|------------------
Go (native) | a4f8e2c1... | 0.00000000
Python | a4f8e2c1... | 0.00000000
JavaScript | a4f8e2c1... | 0.00000001
C# | a4f8e2c1... | 0.00000000
WASM | a4f8e2c1... | 0.00000002
Android | a4f8e2c1... | 0.00000001

3. Zero-Dependency Deployment

Traditional ML stacks require:

  • Python runtime (300MB+)
  • NumPy, SciPy (100MB+)
  • PyTorch or TensorFlow (2GB+)
  • CUDA libraries for GPU (several GB)

LOOM requires:

  • Single compiled binary (~10MB)
  • Model file (varies by model size)

That’s it. No pip install, no virtual environments, no dependency conflicts.

Deployment comparison:

Stack Binary Size Dependencies Platforms PyTorch N/A (Python) Python + 2GB libs Linux, Windows (x86) TensorFlow N/A (Python) Python + 500MB libs Linux, Windows, limited mobile ONNX Runtime 50–100MB C++ runtime Most platforms (with effort) LOOM 10MB Zero All platforms, identical API

Supported Models and Performance

Models That Work Right Now

LOOM supports any transformer using the Llama architecture, including:

Text Generation:

  • ✅ Qwen2.5 (0.5B — 7B parameters)
  • ✅ SmolLM2 (135M — 1.7B parameters)
  • ✅ TinyLlama (1.1B parameters)
  • ✅ Mistral (7B parameters)
  • ✅ Llama 2/3 (with appropriate quantization)

Just released models work immediately — if it’s on HuggingFace with Llama-style architecture, LOOM loads it.

Performance Characteristics

Current state (v0.0.3):

  • CPU-only implementation
  • ~0.5–3 tokens/second on small models (SmolLM2–360M)
  • Deterministic across all platforms
  • Full forward + backward passes for training

This is deliberately “correctness-first”:

  • No platform-specific optimizations that break determinism
  • No CUDA randomness
  • No vendor-specific math libraries
  • Reproducible outputs for compliance/auditing

GPU acceleration (in progress):

  • WebGPU compute shaders for Dense, Conv2D, Attention layers
  • Expected 10–50x speedup on supported operations
  • Maintaining determinism is the priority

Memory and Storage

Model Parameters Disk Size RAM Required Typical Use Case SmolLM2–135M 135M ~270MB ~500MB Mobile, embedded, quick responses SmolLM2–360M 360M ~720MB ~1GB Balanced quality/size for mobile Qwen2.5–0.5B 500M ~1GB ~1.5GB Desktop, high-quality generation TinyLlama-1.1B 1.1B ~2.2GB ~3GB Desktop, specialized tasks

Installation and Quick Start

For Python Developers

pip install welvetfrom welvet import Transformer# Load any HuggingFace model (downloads automatically if needed)
Transformer.load_tokenizer("HuggingFaceTB/SmolLM2-360M-Instruct")
Transformer.load_model("HuggingFaceTB/SmolLM2-360M-Instruct")
# Generate text
result = Transformer.generate("The meaning of life is", max_tokens=50)
print(result.text)
# Streaming generation (token-by-token)
for token in Transformer.generate_stream("Once upon a time", max_tokens=100):
print(token, end='', flush=True)

For JavaScript/TypeScript Developers

npm install @openfluke/welvetimport { initLoom } from '@openfluke/welvet';async function main() {
// Initialize WASM module
const loom = await initLoom();

// Load model (works in Node.js and browsers)
await loom.LoadTransformer("HuggingFaceTB/SmolLM2-360M-Instruct");

// Generate text
const result = loom.Generate("The future of AI is", 50);
console.log(result);
}

Browser-native inference — no server needed:

<script type="module">
import { initLoom } from 'https://cdn.jsdelivr.net/npm/@openfluke/welvet/+esm';
// Now running a transformer entirely in the browser
</script>

For C# / .NET Developers

dotnet add package Welvetusing Welvet;// Load model
Transformer.LoadTokenizer("HuggingFaceTB/SmolLM2-360M-Instruct");
Transformer.LoadModel("HuggingFaceTB/SmolLM2-360M-Instruct");
// Generate text
var result = Transformer.Generate("In a galaxy far away", maxTokens: 50);
Console.WriteLine(result.Text);
// Streaming (Unity/Godot game integration)
foreach (var token in Transformer.GenerateStream("Player: Hello\nNPC:", 100))
{
Console.Write(token); // Display in real-time
}

For Go Developers

go get github.com/openfluke/loom/nnpackage mainimport (
"fmt"
"github.com/openfluke/loom/nn"
"github.com/openfluke/loom/tokenizer"
)
func main() {
// Load tokenizer and model
tk, _ := tokenizer.LoadFromFile("models/SmolLM2-360M/tokenizer.json")
network, _ := nn.LoadTransformerFromSafetensors("models/SmolLM2-360M")

// Generate text
prompt := "The key to success is"
tokens := tk.Encode(prompt, false)

// Run inference
// (Full example in repo)
}

The Game Engine Integration: A First

Why Game Engines Matter

Video games are one of the most demanding AI environments:

  • Real-time performance (30–60 FPS, no stuttering)
  • Local execution (no internet dependency for single-player)
  • Platform variety (PC, consoles, mobile)
  • Resource constraints (memory, CPU budget)

Traditional ML frameworks don’t work for games because:

  • ❌ Unity ML-Agents requires Python server (can’t ship to players)
  • ❌ TensorFlow has massive runtime (too big for games)
  • ❌ Cloud APIs introduce latency (breaks immersion)
  • ❌ Platform fragmentation (different tools for PC vs console)

LOOM + Godot: Native AI in Games

LOOM integrates with Godot Engine via C-ABI, enabling:

Local LLM-powered NPCs:

# GDScript (Godot's scripting language)
var ai = load("res://loom.gdnlib")
func _ready():
ai.load_model("SmolLM2-360M-Instruct")
func talk_to_npc(player_message):
var context = "You are a wise wizard. Player says: " + player_message
var response = ai.generate(context, 100)
display_dialogue(response)

What this enables:

  • NPCs that remember past conversations (stored in game save)
  • Dynamic quest generation based on player history
  • Procedural dialogue that fits game context
  • All running offline, no API costs, works on any platform

First working demo: Watch LOOM running in Godot

Mobile demo: SmolLM2 on Android in a game engine

Extending to Other Engines

The C-ABI means LOOM can integrate with:

  • Unity (via P/Invoke, like the C# package)
  • Unreal (via C++ FFI)
  • Custom engines (any engine with C interop)

Unity example:

using Welvet;public class NPCController : MonoBehaviour {
void Start() {
Transformer.LoadModel("SmolLM2-360M-Instruct");
}

public string GetNPCResponse(string playerInput) {
return Transformer.Generate("NPC: " + playerInput, 50).Text;
}
}

The Privacy Angle: AI Without Surveillance

Why Local AI Matters

Cloud AI has a fundamental problem: your data becomes their data.

When you use ChatGPT, Claude, or Gemini:

  • Your conversations are stored on their servers
  • They can analyze your usage patterns
  • They may use your data for training (depending on terms)
  • Government subpoenas can access your history
  • Service outages mean no access
  • Price changes affect your costs
  • Content policies can restrict what you can ask

LOOM flips this:

  • All processing happens on your device
  • No data sent to external servers
  • No usage tracking or analytics
  • Works in airplane mode
  • Can’t be censored or shut down
  • Zero ongoing costs after model download

Use Cases That Require Privacy

Healthcare:

  • Medical note-taking assistants
  • Patient symptom analyzers
  • Clinical decision support
  • All must comply with HIPAA (no cloud allowed)

Legal:

  • Contract analysis
  • Case research
  • Client communication drafting
  • Attorney-client privilege (can’t use cloud)

Financial:

  • Personal finance advisors
  • Trading strategy analysis
  • Sensitive document review
  • Regulatory compliance (data sovereignty)

Personal:

  • Journaling with AI feedback
  • Therapy/mental health chatbots
  • Creative writing assistance
  • Private brainstorming

LOOM enables all of these without compromise.

Platform Coverage: Where LOOM Runs

  • MAE < 1e-8 ensures outputs match exactly
  • Hash inputs/outputs for audit logs
  • No cloud dependency = no data leakage

The Technology Stack: How LOOM Works Under the Hood

Core Architecture

Language: Pure Go (with C-ABI for foreign function interface)

Why Go:

  • Compiles to native binaries (fast execution)
  • Cross-compilation built-in (one command for any platform)
  • No runtime dependency (unlike Python)
  • Memory safe (unlike C/C++)
  • Excellent concurrency support (goroutines)
  • Growing ecosystem

Layer Implementation

LOOM implements 10 layer types, all with full CPU forward and backward passes:

1. Dense (Fully-Connected)

  • Matrix multiplication with activation
  • Supports: ReLU, Sigmoid, Tanh, Softplus, LeakyReLU, Linear
  • Used in: MLPs, feedforward networks, output layers

2. Conv2D (2D Convolution)

  • Standard convolution with stride, padding, dilation
  • Multiple filters, channels, activations
  • Used in: Image processing, spatial feature extraction

3. Multi-Head Attention

  • Transformer-style scaled dot-product attention
  • Supports Grouped Query Attention (GQA) for efficiency
  • Q/K/V projections with output projection
  • Used in: Transformers, sequence modeling

4. RNN (Recurrent Neural Network)

  • Simple recurrent layer with hidden state
  • Backpropagation Through Time (BPTT)
  • Used in: Sequence modeling, time series

5. LSTM (Long Short-Term Memory)

  • Forget, input, output, cell gates
  • Addresses vanishing gradient problem
  • Used in: Long sequences, temporal dependencies

6. LayerNorm (Layer Normalization)

  • Normalizes across feature dimension
  • Learned scale (gamma) and shift (beta)
  • Used in: Transformers, stabilizing training

7. RMSNorm (Root Mean Square Normalization)

  • Llama-style normalization (no beta parameter)
  • More efficient than LayerNorm
  • Used in: Modern transformers (Llama, Qwen, Mistral)

8. SwiGLU (Swish-Gated Linear Unit)

  • Gated activation: down(silu(gate(x)) * up(x))
  • Used in Llama/Qwen FFN layers
  • Better than standard ReLU for transformers

9. Softmax (10 variants)

  • Standard, Grid, Hierarchical, Temperature, Gumbel
  • Masked, Sparsemax, Entmax, Adaptive, Mixture
  • Grid Softmax = Native MoE (mathematically proven)

10. Residual (Skip Connections)

  • Adds input to output (residual connections)
  • Essential for deep networks
  • Used in: ResNets, Transformers

The Tokenizer: Pure Go BPE

Most frameworks depend on HuggingFace’s transformers library (Python) for tokenization.

LOOM implements BPE (Byte Pair Encoding) from scratch in Go:

  • Loads tokenizer.json directly
  • Supports multiple encoding schemes (GPT-2, Llama, Qwen, T5)
  • No Python dependency
  • Identical behavior to HuggingFace tokenizers

Why this matters:

  • Desktop apps don’t need Python installed
  • Mobile apps can tokenize on-device
  • WASM runs without external libraries
  • Deterministic across platforms

Model Loading: Direct Safetensors Support

Safetensors format:

  • Developed by HuggingFace as safer alternative to pickle
  • Binary format with header + tensors
  • No arbitrary code execution (unlike pickle)
  • Memory-mapped for efficiency

LOOM’s implementation:

// Load model from HuggingFace directory
network, err := nn.LoadTransformerFromSafetensors("models/SmolLM2-360M")
// Or from bytes (for embedding in apps)
configBytes, _ := os.ReadFile("config.json")
weightsBytes, _ := os.ReadFile("model.safetensors")
network, err := nn.LoadTransformerFromBytes(configBytes, weightsBytes)

No conversion needed. If it’s on HuggingFace, LOOM loads it.

C-ABI: The Universal Interface

C Application Binary Interface is how LOOM talks to other languages:

// C header (auto-generated)
typedef void* NetworkHandle;
NetworkHandle LoadModel(const char* modelPath);
char* Generate(NetworkHandle handle, const char* prompt, int maxTokens);
void FreeNetwork(NetworkHandle handle);

Bindings for each language:

  • Python: Uses ctypes to call C functions
  • JavaScript: WASM exports C functions automatically
  • C#: Uses DllImport (P/Invoke) to call native library
  • Go: Native (no FFI needed)

Result: Same underlying C library, different language-specific wrappers.

Frequently Asked Questions

Technical Questions

Q: Can LOOM train models, or just run inference?

A: LOOM has full forward and backward passes for all layers, so training is possible. However, it’s optimized for inference. For training large models, use PyTorch/JAX, then export to LOOM for deployment.

Q: Why is LOOM slower than PyTorch on GPU?

A: Current version is CPU-only with focus on correctness and determinism. GPU acceleration is in progress. When complete, it will be competitive for inference while maintaining determinism.

Q: What about models that aren’t Llama-architecture?

A: Currently, LOOM focuses on transformer architectures used by most modern LLMs. Future versions will expand to other architectures based on community needs.

Q: Can I use LOOM with my existing PyTorch models?

A: If your model is available on HuggingFace or uses Llama-style architecture, yes. For custom models, you’d need to export weights to the LOOM format (guide coming).

Q: How does determinism work across different CPU architectures?

A: LOOM uses explicit floating-point operations and avoids architecture-specific optimizations that introduce non-determinism. This is validated through extensive cross-platform testing.

Deployment Questions

Q: What’s the memory footprint in production?

A: Depends on model size:

  • SmolLM2–135M: ~500MB RAM
  • SmolLM2–360M: ~1GB RAM
  • Qwen2.5–0.5B: ~1.5GB RAM
  • TinyLlama-1.1B: ~3GB RAM

Binary itself is ~10MB.

Q: Can I bundle models with my app?

A: Yes. Models can be embedded in the app bundle (mobile) or downloaded on first run. Example code in the documentation.

Q: Does LOOM work offline after initial model download?

A: Yes, completely. Once the model is downloaded, no internet connection is needed ever again.

Q: What about updates to models?

A: Download new model version, swap out the file, restart app. LOOM’s determinism means you can validate the new model behaves identically across all deployments before rolling out.

Privacy and Security Questions

Q: Does LOOM send any telemetry?

A: No. Zero telemetry, analytics, or data collection. Everything runs locally.

Q: Can I audit what LOOM is doing?

A: Yes. LOOM is open source. Audit the code, compile it yourself, verify the binaries match.

Q: Is LOOM HIPAA/GDPR compliant?

A: LOOM itself is just a library (no data collection), so it doesn’t have compliance obligations. However, its local-only processing makes it suitable for building compliant applications. Consult your compliance team.

Q: What about model licensing?

A: LOOM is Apache 2.0 (permissive). Models have their own licenses (check HuggingFace). Most open models allow commercial use, but verify before deploying.

Business Questions

Q: Is LOOM free for commercial use?

A: Yes. Apache 2.0 license allows commercial use without fees.

Q: Do you offer commercial support?

A: Not yet, but it’s on the roadmap. For now, support is community-based via GitHub issues and discussions.

Q: Can I get consulting help for integration?

A: Contact via GitHub issues. May consider consulting engagements depending on project scope.

Q: Will LOOM stay open source?

A: Yes. Core LOOM will always be open source. Potential future commercial offerings would be additional services (support, hosted tools, enterprise features), not the core framework.

The Bigger Picture: Why This Matters

The Current AI Landscape

We’re at an inflection point in AI:

The Cloud Era (2020–2024):

  • All AI happens in datacenters
  • Users send data to APIs
  • Pay per token
  • No privacy
  • Internet required

The Edge Era (2025+):

  • AI runs on devices
  • Data stays local
  • One-time cost
  • Total privacy
  • Works offline

LOOM is infrastructure for the Edge Era.

What’s Changing

Hardware:

  • Modern smartphones = 2015 datacenter performance
  • Neural accelerators in every device (Apple Neural Engine, Qualcomm NPU)
  • RAM increasing (8GB+ is common in phones now)
  • Storage is cheap (256GB+ standard)

Models:

  • Smaller models (1–7B parameters) are surprisingly good
  • Quantization makes them even smaller
  • Specialized models beat generalist models for specific tasks
  • Open source models competitive with closed APIs

Regulation:

  • GDPR, CCPA, HIPAA all restrict cloud data
  • AI Act in EU requires transparency
  • Data sovereignty becoming standard
  • Privacy is a competitive advantage

Economics:

  • Cloud AI costs add up fast ($1M+/month for moderate apps)
  • One-time hardware cost < ongoing API fees
  • Edge inference is essentially free after model download
  • Enables sustainable business models

The Privacy Revolution

People are waking up to surveillance capitalism:

  • Your conversations shouldn’t train someone else’s model
  • Your medical data shouldn’t leave your device
  • Your creative work shouldn’t feed corporate AI
  • Your private thoughts shouldn’t be stored in someone else’s datacenter

Local AI isn’t just technically better. It’s ethically better.

The Accessibility Angle

Cloud AI creates inequality:

  • Geographic: Requires fast internet (excludes rural, developing nations)
  • Economic: Pay-per-use excludes low-income users
  • Political: Censorship and control by platform owners

Local AI democratizes access:

  • Works everywhere, even offline
  • One-time cost (or free with open models)
  • Can’t be censored or shut down
  • Users control their own AI

LOOM makes powerful AI accessible to everyone, everywhere.

Conclusion: The Future Is Local

LOOM started as a solution to deployment hell. It became something bigger: infrastructure for the post-cloud AI era.

What we’ve built:

  • ✅ Universal runtime (8 platforms, one model file)
  • ✅ Deterministic outputs (provable, auditable)
  • ✅ Zero dependencies (10MB binary)
  • ✅ Privacy-first (everything local)
  • ✅ Game engine native (first of its kind)
  • ✅ Production packages (PyPI, npm, NuGet)

What this enables:

  • Offline-first mobile apps
  • Privacy-preserving healthcare tools
  • Intelligent game NPCs
  • Edge computing solutions
  • Compliant enterprise AI
  • Accessible AI for everyone

The vision: AI that works everywhere, costs nothing to run, respects privacy, and empowers users instead of corporations.

We’re not there yet. GPU acceleration needs work. More layers would help. The ecosystem is young.

But the foundation is solid. And it’s already working in production.
