A Marvel of Quantization: Shakti’s Breakthroughs

Quantization is a cornerstone for deploying AI in resource-constrained environments. However, it comes with inherent challenges—chief among them being the risk of performance degradation. Yet, Shakti models break this norm, redefining what’s possible:

Exceptional Precision at Int8 and Int4:

Shakti models outperform competitors in reasoning, language understanding, and domain-specific tasks, even when quantized to lower bit-widths.
For instance, the Shakti-2.5B Int8 model delivers 96% of baseline accuracy in PiQA and leads benchmarks like MMLU (69.2%), outperforming Phi-3.5 Mini and Llama 3.

Balancing Performance with Efficiency:

- While many models struggle to maintain logical integrity at Int4, Shakti-250M retains 85%+ precision in tasks like WinoGrande and PiQA.
- These capabilities translate directly to practical advantages, from edge deployments to real-time analytics.

Architectural Innovations That Drive Excellence

The Shakti LLM Series achieves unmatched performance, even in aggressively quantized configurations like Int8 and Int4, through a suite of architectural innovations. These features ensure precision, efficiency, and adaptability across a range of applications, making Shakti models stand out in the competitive AI landscape.

Variable Grouped Query Attention (VGQA): VGQA dynamically adjusts attention mechanisms, optimizing the handling of long-context inputs. This ensures minimal loss of reasoning and comprehension, even when the models are highly quantized. By intelligently grouping and distributing computational focus, VGQA enhances efficiency without compromising on logical integrity.
SwiGLU Activations: This advanced activation function significantly improves computational flow, enabling seamless adaptation to lower bit-width operations such as Int4. SwiGLU reduces the performance loss commonly associated with quantization by optimizing activation dynamics and ensuring robust representation of data features.
Rotary Positional Embeddings (RoPE): RoPE plays a pivotal role in preserving the positional integrity of sequential data. This is crucial for tasks requiring an understanding of order and relationships, such as long-form text generation and reasoning. RoPE ensures that quantized models, even at Int4, can manage complex linguistic structures and dependencies effectively.
Sliding Window Inference: Sliding window inference is particularly vital for the Shakti-250M and 100M models, allowing them to process long text sequences by breaking them into smaller, manageable chunks while retaining contextual continuity. This approach is a cornerstone for real-time applications, enabling smaller models to handle tasks typically requiring larger architectures. In quantized configurations, it mitigates the risk of accuracy degradation by maintaining coherence across the input spans. Sliding window inference ensures that compact models like Shakti-250M and 100M excel in tasks such as conversational AI, legal text analysis, and document summarization, even in resource-constrained scenarios.
