Summary
The LLM Architecture Gallery compiles architecture figures and fact sheets from significant LLM comparisons. Users can enlarge figures and navigate to corresponding sections using model titles.
Key Takeaways
- The Llama 3 model features 8 billion parameters and utilizes a dense decoder with GQA and RoPE attention mechanisms, focusing on a pre-norm baseline.
- The DeepSeek V3 model has a total of 671 billion parameters, employing a sparse MoE decoder and MLA attention, with a training recipe oriented towards reasoning.
- Gemma 3 is designed with 27 billion parameters and emphasizes local attention, utilizing a sliding-window/global attention strategy for multilingual capabilities.
- The GPT-OSS 120B model maintains an alternating attention structure similar to its 20B counterpart, scaled up for OpenAI's flagship open-weight release.
