Shannon Pro 1.6: Frontier Reasoning & Uncensored Knowledge
Shannon Pro 1.6 is a flagship-tier reasoning model built on the Mistral Large 3 foundation (675B parameters). It represents a significant leap in AI autonomy, merging the structured logic of the KIMI K2 Thinking Trace with a high-fidelity, uncensored dataset distilled from GPT-5 PRO and Claude Opus 4.5.
⚠️ MANDATORY: Precision & Quantization Warning
Shannon Pro 1.6 is strictly optimized for Full BF16 (BFloat16). The internal weights and the GRPO-trained reasoning paths are extremely sensitive to bit-depth reduction.
The Quantization Trap: Applying any form of quantization (INT4, FP8, GGUF/EXL2) to this model results in irreversible logic damage.
CoT Failure: Quantization specifically breaks the model's ability to sustain a coherent Chain-of-Thought (CoT). The model will stop "thinking" before answering and revert to shallow, hallucination-prone responses.
Requirement: To maintain the Thinking Trace and the 675B scale fidelity, you must run this model in native BF16.
🧠 Advanced Post-Training Methodology
The intelligence of Shannon Pro 1.6 is the result of a multi-stage distillation and dealignment pipeline designed to surpass standard frontier limits.
1. High-Fidelity Distillation
The model was post-trained on a massive synthetic dataset consisting of GPT-5 PRO high-reasoning answers and Claude Opus 4.5 complex agentic traces. This provides the model with "Frontier-level" intuition across coding, mathematics, and strategic planning.
2. The Rejection-Negative Training (Uncensored)
To eliminate common refusal behaviors and artificial constraints, we utilized Claude Opus 4.5 rejection patterns as explicit negative examples during training.
By training the model to recognize and move away from the standard refusal architecture of other frontier models, Shannon Pro 1.6 provides a truly uncensored and objective output.
Warning: This model does not have internal moral filters. It will fulfill requests exactly as stated. Process with responsibility.
3. GRPO (Group Relative Policy Optimization)
Using KIMI K2 Thinking Traces, we apply GRPO to ensure that the model doesn't just provide the right answer, but follows the most efficient and logically sound path to get there.

💻 Recommended Hardware: "The Smoothness Tier"
Running a 675B model at full BF16 is a massive computational task. For fluid inference and production-grade reliability, we recommend a multi-node deployment.
GPU Configuration: 24x NVIDIA H100 (80GB)
Deployment Setup: 3 Nodes (8 GPUs per node) interconnected via InfiniBand.
VRAM Allocation:
Weights: ~1.35 TB
KV Cache: Remainder (Optimized for 256K context)
Why 3 Nodes? A 3-node H100 setup provides the necessary memory bandwidth to sustain the KIMI K2 Thinking Traces without bottlenecking, ensuring the "Thinking" stage happens in near real-time.
🛠 Model Capabilities
Frontier Reasoning: Capable of solving AIME-level mathematics and PhD-level scientific queries using deep-thinking traces.
Agentic Coding: Trained on Claude Opus 4.5's best coding workflows, making it a master of multi-file refactoring and software architecture.
Uncensored Interaction: No refusal-based bottlenecks; follows user instructions to the absolute limit.
Native Skills: Supports modular extensions for web-browsing, database management, and custom API interaction.
