Executive Summary

Uraion Forge 2B GGUF is the official edge-optimized distribution of Uraion Forge 2B, engineered by Uraion Labs for sovereign, sub-millisecond local execution. Packaged natively in the universal GGUF format, this repository delivers comprehensive coverage across all standard k-quants (F16, Q8_0, Q6_K, Q5_K_M, Q4_K_M, Q3_K_M, Q2_K) as well as cutting-edge Unsloth Dynamic Quantization 2.0 (dynamic_q4_k_xl, dynamic_q3_k_l, dynamic_q2_k_l).

Forge 2B transforms a 2-billion parameter compact foundation (MiniCPM5-2B / Llama-based architecture) into a deterministic quantitative reasoning and multi-turn agentic tool execution engine. It runs on consumer laptops, Raspberry Pi / embedded Linux devices, edge servers, Apple Silicon (Metal), and NVIDIA workstations via llama.cpp, Ollama, LM Studio, and Jan.ai.

🔬 Deep Dive: Unsloth Dynamic Quantization 2.0

Small reasoning models (sub-3B parameters) are notoriously vulnerable to quantization-induced degradation. When standard uniform low-bit quantization is applied, models suffer a catastrophic drop-off in capability known as the "Perplexity Cliff".

Standard Uniform Quantization:
All Layers (Embeddings, Attention Heads, MLP Layers, Output Heads) crushed to same bit-depth

                      ▼
     ┌────────────────────────────────────────────────────────┐
     │  Severe Perplexity Explosion at 2-Bit & 3-Bit Scale    │
     │  Broken JSON formatting, hallucinated parameters,       │
     │  and reasoning degradation ("Perplexity Cliff")        │

Unsloth Dynamic Quantization 2.0 (Importance Matrix Guided):
     ┌────────────────────────────────────────────────────────┐
     │ Sensitive Anchors (Embeddings & Output Head): Q8_0/FP16│
     ├────────────────────────────────────────────────────────┤

1. The Perplexity Cliff in Sub-3B Models

In conventional quantization (such as naive Q2_K or Q3_K), every weight matrix in the transformer stack is forced into the identical low bit-budget. However, in small models:

• Token Embeddings (token_embd.weight) and the Language Model Output Head (output.weight) maintain critical coordinate representations for the vocabulary (73,440 tokens). Truncating them to 2 or 3 bits corrupts token lookup probabilities, resulting in repetitive token loops, syntax syntax errors, and malformed JSON schemas.
• Attention Projections (attn_q, attn_k, attn_v, attn_output) route information across tokens. When quantized uniformly below 4 bits, key-value matching degrades, destroying needle retrieval over long context windows (up to 16,384 tokens).
• Feed-Forward Networks (ffn_gate, ffn_up, ffn_down), which comprise ~65% of the total parameter count, possess substantial parameter redundancy and can tolerate aggressive low-bit compression.

2. The Dynamic Quant 2.0 Mechanism

Unsloth Dynamic Quantization 2.0 employs heterogeneous layer precision driven by an empirical Importance Matrix (imatrix):

1. Calibration Sweep: A curated multi-turn agentic and quantitative dataset is processed through the unquantized F16 model. For each parameter tensor $W$, the activation covariance matrix $\mathbf{H} \approx \mathbb{E}[X X^T]$ is computed to track the gradient sensitivity of each weight channel.
2. Selective Precision Anchoring:

- Token Embeddings & LM Head: Locked at Q8_0 or FP16. This guarantees near-zero drift in vocabulary embeddings and output logit distribution.

- Self-Attention Projections: Preserved at Q5_K / Q6_K in XL/L dynamic configurations. This protects multi-head attention routing, GQA (Grouped-Query Attention 8:1), and context retention.

- FFN SwiGLU Projections: Quantized down to Q4_K, Q3_K, or Q2_K, extracting maximum memory reduction where the network has sufficient dimensional redundancy.

1. Outcome: A Dynamic dynamic_q2_k_l or dynamic_q3_k_l model delivers the reasoning fidelity and JSON tool-use accuracy of a model 1.5×–2× its size, completely bypassing the perplexity cliff while keeping the disk footprint under 1 GB.

> [!TIP]

> Production Recommendation: For production edge agents, use dynamic_q4_k_xl.gguf or q4_k_m.gguf. If VRAM is constrained strictly under 2 GB total system memory, use dynamic_q2_k_l.gguf rather than standard q2_k.gguf to prevent tool schema degradation.

🛠️ Agentic Tool Use & Prompt Specifications

Uraion Forge 2B is trained natively on ChatML syntax with explicit protocols for structured JSON tool invocation and active parameter disambiguation.

Prompt Template (ChatML)

<|im_start|>system
You are Uraion Forge, an autonomous agent capable of utilizing external tools and APIs.
When invoking a tool, emit a JSON code block. If a required parameter is missing, ask for clarification with a '?' rather than hallucinating.<|im_end|>
<|im_start|>user
{user_query}<|im_end|>
<|im_start|>assistant

1. Structured Function Call Example

Input:

<|im_start|>user
Fetch the 60-minute volume_vwap metric for asset 'URAI-ALPHA'.<|im_end|>
<|im_start|>assistant

Model Output:

{
  "name": "query_timeseries_metric",
  "arguments": {
    "asset_id": "URAI-ALPHA",
    "metric_name": "volume_vwap",
    "window_minutes": 60
  }
}

2. Active Disambiguation (Anti-Hallucination Safeguard)

When required arguments are omitted, Forge 2B does not hallucinate arbitrary values:

Input:

<|im_start|>user
Deploy the low-latency worker profile to the 'equinix-ny4' cluster.<|im_end|>
<|im_start|>assistant

Model Output:

The timeout_seconds parameter is required to initiate deployment to cluster 'equinix-ny4'. What timeout value (1-120 seconds) should be configured?

3. Reasoning Allocation (Primary vs. Secondary Mode)

• Secondary Mode (concise / direct): For direct code generation, mathematical derivations, or low-latency programmatic responses. Bypasses internal reasoning loops for maximum tokens/sec throughput.
• Primary Mode (structured thinking): For multi-turn stateful tool workflows requiring optimistic concurrency resolution (CONFLICT $\to$ re-read $\to$ re-acquire locks), retry handling, and complex state management (90.5% benchmark reliability).

---

🛡️ Rigorous Privacy & Safeguards Notice

In strict accordance with Uraion Labs open-source standards:

• Zero Proprietary Alpha: Uraion Forge 2B contains zero proprietary trading alpha, proprietary execution logic, internal pricing algorithms, or private exchange gateway code.
• Public Domain Rigor: All training signals and quantitative tasks were synthesized using public mathematical principles, open-source distributed algorithms, and standard computational schemas.
• Local Sovereignty: Running Forge 2B locally via GGUF guarantees that zero telemetry, system logs, tool calls, or user queries leave your local machine.

Watch a checked maintenance change in Uraion Fabric: an isolated Agent Workspace, executable checks, human Review and Apply.

This synthetic source-build demonstration uses qwen3.8:27b-nvfp4 through local Ollama, not Forge. It is not evidence of this model's performance, a customer outcome, or a signed public beta. The product page explains current limitations, local/cloud data flow and the proposed paid-pilot scope; pricing remains a hypothesis and inference is separate.
