Akhorika E2B Base (আখৰিকা) is a foundational 2.69B parameter language model (1.91B active text decoder parameters) continued-pretrained (CPT) on Assamese language corpora, based on Google's Gemma 4 E2B architecture.

Model Details

Model Name: Akhorika E2B Base
Base Architecture: Gemma4ForConditionalGeneration (Google Gemma 4 E2B)
Parameters: 2.69B total (1.91B text decoder parameters)
Tokenizer: Custom 32,000 vocab Assamese-first SentencePiece Unigram tokenizer (replacing the native 256k tokenizer)
Embedding Initialization: FOCUS (semantic subword surface-form projection from base Gemma embeddings)
Languages: Assamese (as), English (en)
Training Type: Continued Pretraining (CPT)
Checkpoint: Step 821 / 821 (epoch 1 complete)
Eval Loss: 4.09 (PPL ~60 on the held-out Assamese eval set)

Quickstart & Inference

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "ananddey/akhorika-e2b-base"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    attn_implementation="sdpa"
)

prompt = "অসম ভাৰতৰ উত্তৰ-পূব অঞ্চলৰ"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
