How Does Generative AI Work? There are two answers to the question of how generative AI models work. Empirically, we know how they work in detail because humans designed their various neural network implementations to do exactly what they do, iterating those designs over decades to make them ...
The developers gave the system specific tasks to complete (e.g., answering questions or generating creative work) Humans rated the LLM’s response for effectiveness and fed these ratings back into the model so it understood its performance RLHF’s fine-tuning made ChatGPT more effective at gene...
RLHF was used to fine-tune OpenAI’s GPT 3.5 model to help create the ChatGPT chatbot that went viral. But how did the model answer my question? It’s a mystery. Here’s how Thompson explains the current state of understanding: “There’s a huge ‘we just don’t know’ in the ...

The encoder does the work of processing input text, while the decoder is used to generatetheoutput text.Also,amulti-head attention mechanismis used,which is a key component of the Transformer architecture, allowingthe model to attend to different parts of the input sequence simultaneously, which ...
I have a workaround (which I think is too ugly, lol): model.hf_device_map['transformer.output_layer'] = model.hf_device_map['transformer.embedding'] model = AutoModel.from_pretrained("THUDM/chatglm2-6b", trust_remote_code=True, device_map=model.hf_device_map) which is to manually ...
While OpenAI does great work, customers are concerned about privacy and intellectual property—what happens to the data you send to closed models? We believe there’s room for both open and closed models, and at the end of the day customers decide what works best for them. Aru...
Over the last two decades, the understanding of how dysregulated ion channels and transporters are involved in carcinogenesis and tumor growth and progression, including invasiveness and metastasis, has been increasing exponentially. The present review s
