 # Multilingual support for Transformer Visualizer
 
+This summarises how we would implement multilingual support without TransformerLens.
 To generalize, for different langauges, we have to:
 1. In the backend (for Transformer Explainer, src/utils/model, change `modelname`), export the model to ONNX if we want to run on the browser. If not, and if we want to do everything in the backend, use AutoModelForCausalLM . 
 2. we would have to use a separate tokenizer too using AutoTokenizer (usually included in the Transformers library)

 # Language Support in Transformer Lens
 
 ## Quick Summary
-- TransformerLens just uses model weights as-is;it doesn't modify how the model handles multilingualism, it just lets you inspect it!
-- MWork: LLMs process non-English input in three stages: convert to English-centric representations --> reason in English --> convert back to original language
-    - It's not actual translation

     - Self-attention handles reasoning (English-centric), FFNs handle factual knowledge retrieval (multilingual), these are separable
     - Just 0.13% of neurons being deactivated can destroy multilingual capabilities entirely. This shows how concentrated the language-switching work is
 - Neuron behaviour is input dependent, not fixed. A "language-specific" neuron per MWork might behave differently on a different input.

 The authors hypothesize that the process, known as MWork, is how multilingual models work. 
 They test the hypothesis using PLND (Parallel Language-specific Neuron Detection), which finds language-specific neurons that are consistently activated when processing documents in a specific language.

 Although all-shared only makes up of ~20% of neurons in BLOOM (~30% in BLOOMZ, BLOOM-560m, the model we're using may have a lower percentage since it doesn't have IFT), regardless the language inputs, all-shared neurons are the top contributing neurons to the outputs at every layer. Specifically, "they contribute 91.6% to the generation of the correct output in the German test set". So, language-specific neurons are more about surface-level switching than actual correctness.
 - They then propose at the end that increasing all-shared neurons (via replacing or IFT, instruction fine-tuning) can "significantly enhance the accuracy of an LLM in multilingual tasks."
