via “model architecture comparison across paradigms (encoder-only, encoder-decoder, decoder-only)”

📚 从零开始构建大模型

Unique: Organizes three major transformer paradigms into parallel chapters (chapter 3) with identical implementation patterns, making architectural differences explicit through code rather than conceptual descriptions, enabling direct comparison of attention masking, loss computation, and training objectives

Course to get into Large Language Models (LLMs) with roadmaps and Colab notebooks.

Unique: Organizes transformer architecture as a dedicated foundational section with explicit coverage of decoder-only vs. encoder-decoder variants, tokenization, and attention mechanisms. Most LLM courses assume transformer knowledge; this provides structured learning for those needing to build it from scratch.

vs others: More comprehensive than blog post explanations; more accessible than original research papers because it curates multiple explanations and implementations

via “instruction-following with complex multi-step tasks”

This is a series of models designed to replicate the prose quality of the Claude 3 models, specifically Sonnet(https://openrouter.ai/anthropic/claude-3.5-sonnet) and Opus(https://openrouter.ai/anthropic/claude-3-opus).

* ⭐ 04/2023: [Align your Latents: High-Resolution Video Synthesis with Latent Diffusion Models (VideoLDM)](https://arxiv.org/abs/2304.08818)

Unique: Introduces a systematic two-stage alignment approach that decouples vision encoding from language understanding, using adapter modules and LoRA-style parameter-efficient fine-tuning to maintain frozen pre-trained weights while achieving strong instruction-following performance. This contrasts with end-to-end training approaches by reducing memory overhead and enabling faster iteration on instruction datasets.

vs others: More parameter-efficient and faster to train than full model fine-tuning (e.g., BLIP-2, LLaVA v1.0 early approaches) while achieving comparable or superior instruction-following accuracy through explicit alignment objectives rather than implicit joint training.
