The post walk through a (mostly) complete implementation of a GPT-style Transformer, but the goal will not be running code; instead, they use the language of software engineering and programming to explain how these models work and articulate some of the perspectives they bring to them when doing interpretability work.
  - Efficient Long Sequence Modeling via State Space Augmented Transformer (paper) - The quadratic computational cost of the attention mechanism limits its practicality for long sequences. There are existing attention variants that improve the computational efficiency, but they have limited ability to effectively compute global information. In parallel to Transformer models, state space models (SSMs) are tailored for long sequences, but they are not flexible enough to capture complicated local information. They propose SPADE, short for State sPace AugmenteD TransformEr, which performs various baselines, including Mega, on the Long Range Arena benchmark and various LM tasks. This is an interesting direction. SSMs and Transformers were combined a while back.

This approach enables faster training and inference while maintaining or improving performance compared to LONGT5. The main components of COLT5 include routing modules, conditional feedforward layers, and conditional attention layers. Routing modules select important tokens for each input and component, while the light branches process all tokens with lower capacity operations, and heavy branches apply higher capacity operations only on selected important tokens.

  - nGPT: Normalized Transformer with Representation Learning on the Hypersphere - A novel Transformer architecture where all vectors (embeddings, MLP, attention matrices, hidden states) are normalized to unit norm and operate on a hypersphere. Achieves 4-20x faster convergence during training compared to standard Transformers. Eliminates the need for weight decay by enforcing normalization. Normalization approach: matrix-vector multiplications become dot products bounded in [-1,1]. Architecture changes: 1) Attention mechanism - normalizes QKV projection matrices, introduces trainable scaling factors for Q-K dot products, 2) Layer structure: introduces learnable "eigen learning rates" (α) for attention and MLP blocks. Theoretical: can be interpreted in the context of Riemannian optimization. Advantages: more stable training, improved performance on downstream tasks, simplified architecture.
  - Differential Transformer - They presents **significant improvements over standard Transformers** in multiple dimensions, with particular emphasis on attention efficiency and practical applications in LM tasks. A new architecture that improves attention mechanisms by reducing attention to irrelevant context. Achieves better performance while requiring fewer parameters and training tokens compared to standard Transformers. Solution: introduces "differential attention" mechanism that calculates attention scores as the difference between two separate softmax attention. This subtraction cancel out noise. It can be implemented efficiently using existing FlashAttention. Scaling efficiency: **needs only ~65% of parameters or training tokens to match standard Transformer performance**. Improvements: 1) Better performance on long sequences up to 64K tokens. 2) Better at finding key information embedded in documents. 3) ICL: more robust to prompt order permutations. 4) Reduces attention misallocation, a primary cause of hallucinations. Technical details: includes headwise normalization to handle sparse attention patterns, etc. Future: development of efficient low-bit attention kernels, potential for compressing KV caches due to sparser attention patterns, etc. [Listen to [NotebookLM podcast](https://notebooklm.google.com/notebook/8e4c0907-8b12-4bc9-9d29-26c03daab71d/audio)]

MoD model can learn to route more complex tokens through more layers (similarly how experts in MoE can specialize to certain domains). The group explores how to optimize compute budget and improve efficiency without sacrificing performance. Results: MoD matches baseline performance with 66% faster training. Now, the question is, can it scale above 1B tokens. They tested on 500M tokens.

  - Extending Context Window of Large Language Models via Positional Interpolation - Position Interpolation (PI) is an effective and efficient way to stably extend the context window of RoPE-based pretrained large language models such as LLaMA to much longer lengths (up to 32768) with minimal fine-tuning (within thousandth steps) while maintaining performance.
  - PoSE: Efficient Context Window Extension of LLMs via Positional Skip-wise Training - PoSE simulates longer input sequences during training by manipulating the position indices within a fixed context window, rather than training on the full target length. This allows decoupling of the training length from the target context length, greatly reducing memory and computational requirements compared to full-length fine-tuning. PoSE successfully extended LLaMA-1 to support context lengths up to 128k tokens using only a 2k training window, with minimal performance degradation. [This model](https://huggingface.co/winglian/Llama-3-8b-64k-PoSE) uses PoSE to extend Llama-3 8B context length from 8k to 64k. PoSE has potential to scale context lengths even further, limited only by inference memory, as efficient inference techniques continue improving. [Code: [PoSE](https://github.com/dwzhu-pku/PoSE)]

  - FlashAttention: Fast and Memory-Efficient Exact Attention with IO-Awareness (paper) - Transformers have grown deeper and wider, but training them on long sequences remains difficult. The attention layer at their heart is the compute and memory bottleneck: doubling the sequence length would quadruple the runtime and memory requirements. FlashAttention is a new algorithm to speed up attention and reduce its memory footprint—without any approximation. It enables training LLMs with longer context.

  - Better & Faster Large Language Models via Multi-token Prediction - What happens if we make language models predict several tokens ahead instead of only the next one? They show that replacing next token prediction tasks with multiple token prediction can result in substantially better code generation performance **with the exact same training budget and data — while also increasing inference performance by 3x**. While similar approaches have previously been used in fine-tuning to improve inference speed, **this research expands to pre-training for large models, showing notable behaviors and results at these scales**.

  - RECITE: Recitation-Augmented Language Models (paper) - How can ChatGPT-like models achieve greater factual accuracy without relying on an external retrieval search engine? This paper shows that recitation can help LLMs generate accurate factual knowledge by reciting relevant passages from their own memory (by sampling) before producing final answers. The core idea is motivated by the intuition: recite-step that recollects relevant knowledge pieces helps answer-step (generation) better output. That's a recite-answer paradigm: first ask the LLM to generate the support paragraphs that contain the answer (knowledge-recitation) and then use it as additional prompt, along with the question to ask the LLM to generate the answer. They verify the effectiveness on four LLMs. They also show that recitation can be more effective than retrieval. This is important since having a retriever may lead to unpredictable behavior (i.e., Bing/Sydney). [[code](https://github.com/Edward-Sun/RECITE)]

During pre-training it uses Mixture-of-Denoisers (MoD) that samples from a varied set of such objectives, each with different configurations. MoD combines diverse pre-training paradigms together. They demonstrated that models trained using the UL2 framework perform well in a variety of language domains, including prompt-based few-shot learning and models fine-tuned for down-stream tasks. They open sourced UL2 20B model and checkpoints back in 2022. In 2023, they open sourced Flan-UL2 20B and released the weights. Check out: [[blog post](https://archive.is/20230303191656/https://www.yitay.net/blog/flan-ul2-20b), [Tweet](https://twitter.com/YiTayML/status/1631359474421366784)].

  - Larger language models do in-context learning (ICL) differently (paper) - Overriding semantic priors when presented with enough flipped labels is an emergent ability of scale. LLMs learn better mappings when ICL labels are semantically unrelated to inputs (i.e., apple/orange, negative/positive). Fine-tuning to follow instruction helps both.

  - Fast Transformer Decoding: One Write-Head is All You Need (paper) - They proposed a variant of attention type called **multi-query attention** (MQA). The plain multi-head attention mechanism has one query, key, and value per head; multi-query instead **shares one key and value across all of the different attention "heads"**. In practice, training time remains the same, but **much faster to decode in inference**. MQA significantly improves language models performance and efficiency. Users can get ~10x better throughput and ~30% lower latency on inference. However, MQA can lead to quality degradation, and moreover it may not be desirable to train a separate model just for faster inference. In 2022, PaLM, a decoder-style model and their use of MQA is an interesting architecture improvements over GPT. Recent models that use MQA include [TII's Falcon](https://falconllm.tii.ae/) (2023).
  - GQA: Training Generalized Multi-Query Transformer Models from Multi-Head Checkpoints - They (1) propose a **technique for uptraining existing multi-head attention (MHA) models into models with multi-query attention (MQA)** using 5% of original pre-training compute, and (2) introduce **grouped-query attention (GQA)**, a generalization of MQA which uses an intermediate (more than one, less than number of query heads) number of key-value heads. GQA achieves **benefits close to MHA** with **comparable inference speed to MQA** through reduced number of key-value heads. Models that use MQA include Meta's Llama 2 (2023).

They apply iterative preference optimization to improve reasoning: generate chain-of-thought candidates with LLM, construct preference pairs based on if answer is correct or not, train with DPO + NLL, and repeat. For example, imagine a group of people trying to decide how to allocate a limited budget. Each person has their own priorities and preferences for how the money should be spent. Using the IRPO approach, the group would engage in a back-and-forth discussion, with each person adjusting their preferences based on the arguments and compromises made by the others. Over time, the group would converge on a set of preferences that everyone can accept, even if it's not exactly what any one person wanted initially.

The authors provide empirical insights into the benefits of DPO, including its ability to perform credit assignment, and demonstrate improvements over the base DPO policy using simple beam search, with **potential applications in multi-turn dialogue, reasoning, and agentic systems**.

Given the [new scaling law](https://www.alignmentforum.org/posts/6Fpvch8RR29qLEWNH/chinchilla-s-wild-implications), even if you pump a quadrillion parameters into a model (GPT-4 urban myth), the gains will not compensate for 4x more training tokens.
- Improving language models by retrieving from trillions of tokens - The group explore an alternate path for efficient training with Internet-scale retrieval. The method is known as RETRO, for "Retrieval Enhanced TRansfOrmers". With RETRO **the model is not limited to the data seen during training – it has access to the entire training dataset through the retrieval mechanism. This results in significant performance gains compared to a standard Transformer with the same number of parameters**. RETRO obtains comparable performance to GPT-3 on the Pile dataset, despite using 25 times fewer parameters. They show that language modeling improves continuously as they increase the size of the retrieval database.
