🚀 Eblan 2.0 Flash Lite (EblanForCausalLM)

Eblan 2.0 Flash Lite is a next-generation lightweight language model built on the custom EblanForCausalLM architecture.

By leveraging an innovative O(1) polynomial recurrent state kernel, the model delivers ultra-fast inference with virtually zero memory overhead, running natively via NumPy and Tiktoken.

🏗️ Architecture (EblanForCausalLM)

Unlike traditional Transformer-based models that rely on heavy Attention blocks (Q, K, V), EblanForCausalLM utilizes a single scalar weight vector W (in R¹) with a direct scalar projection layer.

Forward Pass Formulation:

$$y=W\cdot (x^2+x)\cdot \text{vocab\_size}y\; =\; W\; \backslash cdot\; (x^2\; +\; x)\; \backslash cdot\; \backslash text\{vocab\backslash \_size\}$$

Where:

• x = current_id / vocab_size — normalized input token index.
• W — trained scalar weight (eblan-2.0-flash-lite.npy).
• Logits formula for distance-based logit calculation prior to Softmax sampling:

$${\text{Logits}}_i=-\frac{\mathrm{\mid }i-y\mathrm{\mid }}{\tau }\backslash text\{Logits\}\_i\; =\; -\backslash frac\{|i\; -\; y|\}\{\backslash tau\}$$
