About Helios: Origin of the Name, Vision & Engineering Techniques **Helios** is named after **Helios (Ἥλιος)**, the ancient Greek Titan god and personification of the **Sun**, who drove his radiant golden chariot across the sky each day to illuminate the Earth and was revered as the all-seeing guardian of truth and clarity. Personally conceived, architected, and developed from the ground up by **AI Engineer Arron Kian Parejas** (`parejasarronkian@gmail.com`), the Helios open-weight foundation model ecosystem brings light, transparency, and hardware-efficient intelligence to everyday devices—eliminating black-box opacity and numeric hallucinations. ### Core AI Engineering Techniques Used: - **Decoder-Only Causal Transformer**: 6 Model Tiers from **17.84M (`Nano`)** to **5,802.04M (`Flagship`)**. - **Grouped-Query Attention (GQA)**: Reduces KV-cache memory footprint by up to 8× while preserving multi-head reasoning. - **Rotary Position Embeddings (RoPE)**: High-theta context scaling (up to `500,000.0`) supporting context windows from **2,048** up to **65,536 tokens**. - **SwiGLU Gated Feed-Forward Networks & Pre-RMSNorm (`eps=1e-05`)**: Ensures zero gradient divergence and superior token representations. - **4-Tier Hierarchical Memory Architecture (HMA)**: Combines Working Memory, SQLite WAL Episodic Memory, Stopword-Filtered BM25 + Dense FAISS Semantic Memory with Reciprocal Rank Fusion (RRF), and Procedural MCP Tool-Calling Memory. - **Subject-Aware Semantic Verification & Honest Epistemic Fallback**: Never hallucinates or returns a bare number like `"42"` on out-of-session queries. - **Trained Across 68 Curated Datasets Across 14 Domains (`sot/README.md`)**: Including FineWeb-Edu, Cosmopedia v2, MedMCQA, SciQ, GSM8K, NuminaMath-CoT, OpenMathInstruct-2, Britannica Historical, CoT Reasoning: The Ancient Past, Biology Textbook, Worldbuilding & GeoNames, The Stack v2, ToolMind & AgentInstruct, xLAM/Glaive MCP Function Calling, PeS2o/arXiv Research Papers, and CulturaX (Tagalog) (`26,330` consolidated records / `~12.96M` tokens on `/Volumes/One Touch/Helios/datasets/`). --- ## 2.
