 # ExecuTorch
 
-[ExecuTorch](https://pytorch.org/executorch/stable/index.html) is a platform that enables PyTorch training and inference programs to be run on mobile and edge devices. It is powered by [torch.compile](https://pytorch.org/docs/stable/torch.compiler.html) and [torch.export](https://pytorch.org/docs/main/export.html) for performance and deployment.
+[ExecuTorch](https://pytorch.org/executorch/stable/index.html) runs PyTorch models on mobile and edge devices. Export your Transformers models to the ExecuTorch format with [Optimum ExecuTorch](https://github.com/huggingface/optimum-executorch) with the command below.
 
-You can use ExecuTorch with Transformers with [torch.export](https://pytorch.org/docs/main/export.html). The [`~transformers.convert_and_export_with_cache`] method converts a [`PreTrainedModel`] into an exportable module. Under the hood, it uses [torch.export](https://pytorch.org/docs/main/export.html) to export the model, ensuring compatibility with ExecuTorch.

 At the time of writing this guide, LLMs consist of at least a couple billion parameters. Each parameter thereby is made of a decimal number, e.g. `4.5689` which is usually stored in either [float32](https://en.wikipedia.org/wiki/Single-precision_floating-point_format), [bfloat16](https://en.wikipedia.org/wiki/Bfloat16_floating-point_format), or [float16](https://en.wikipedia.org/wiki/Half-precision_floating-point_format) format. This allows us to easily compute the memory requirement to load the LLM into memory:
 
-> *Loading the weights of a model having X billion parameters requires roughly 4 * X GB of VRAM in float32 precision*
+> *Loading the weights of a model having X billion parameters requires roughly 4 \* X GB of VRAM in float32 precision*
 
 Nowadays, models are however rarely trained in full float32 precision, but usually in bfloat16 precision or less frequently in float16 precision. Therefore the rule of thumb becomes:
 
-> *Loading the weights of a model having X billion parameters requires roughly 2 * X GB of VRAM in bfloat16/float16 precision*
+> *Loading the weights of a model having X billion parameters requires roughly 2 \* X GB of VRAM in bfloat16/float16 precision*
 
 For shorter text inputs (less than 1024 tokens), the memory requirement for inference is very much dominated by the memory requirement to load the weights. Therefore, for now, let's assume that the memory requirement for inference is equal to the memory requirement to load the model into the GPU VRAM.
 
 To give some examples of how much VRAM it roughly takes to load a model in bfloat16:

 Today's top-performing LLMs share more or less the same fundamental architecture that consists of feed-forward layers, activation layers, layer normalization layers, and most crucially, self-attention layers.

 Long story short, the default self-attention algorithm quickly becomes prohibitively memory-expensive for large input contexts.
 
 As LLMs improve in text comprehension and generation, they are applied to increasingly complex tasks. While models once handled the translation or summarization of a few sentences, they now manage entire pages, demanding the capability to process extensive input lengths.

 Note that *chat* not only requires the LLM to handle long text inputs, but it also necessitates that the LLM is able to efficiently handle the back-and-forth dialogue between user and assistant (such as ChatGPT).
 
 Once trained, the fundamental LLM architecture is difficult to change, so it is important to make considerations about the LLM's tasks beforehand and accordingly optimize the model's architecture.
 There are two important components of the model architecture that quickly become memory and/or performance bottlenecks for large input sequences.

--   The key-value cache
+- The positional embeddings
+- The key-value cache
 
 Let's go over each component in more detail
 
 ### 3.1 Improving positional embeddings of LLMs
 
 Self-attention puts each token in relation to each other's tokens.
-As an example, the \\( \text{Softmax}(\mathbf{QK}^T) \\) matrix of the text input sequence *"Hello", "I", "love", "you"* could look as follows:
+As an example, the $\text{Softmax}(\mathbf{QK}^T)$ matrix of the text input sequence *"Hello", "I", "love", "you"* could look as follows:
 
 ![](/blog/assets/163_optimize_llm/self_attn_tokens.png)
 
 Each word token is given a probability mass at which it attends all other word tokens and, therefore is put into relation with all other word tokens. E.g. the word *"love"* attends to the word *"Hello"* with 5%, to *"I"* with 30%, and to itself with 65%.
 
 A LLM based on self-attention, but without position embeddings would have great difficulties in understanding the positions of the text inputs to each other.
-This is because the probability score computed by \\( \mathbf{QK}^T \\) relates each word token to each other word token in \\( O(1) \\) computations regardless of their relative positional distance to each other.
+This is because the probability score computed by $\mathbf{QK}^T$ relates each word token to each other word token in $O(1)$ computations regardless of their relative positional distance to each other.
 Therefore, for the LLM without position embeddings each token appears to have the same distance to all other tokens, *e.g.* differentiating between *"Hello I love you"* and *"You love I hello"* would be very challenging.
 
 For the LLM to understand sentence order, an additional *cue* is needed and is usually applied in the form of *positional encodings* (or also called *positional embeddings*).
 Positional encodings, encode the position of each token into a numerical presentation that the LLM can leverage to better understand sentence order.
 
-The authors of the [*Attention Is All You Need*](https://huggingface.co/papers/1706.03762) paper introduced sinusoidal positional embeddings \\( \mathbf{P} = \mathbf{p}_1, \ldots, \mathbf{p}_N \\) .
-where each vector \\( \mathbf{p}_i \\) is computed as a sinusoidal function of its position \\( i \\) .
-The positional encodings are then simply added to the input sequence vectors \\( \mathbf{\hat{X}} = \mathbf{\hat{x}}_1, \ldots, \mathbf{\hat{x}}_N \\) = \\( \mathbf{x}_1 + \mathbf{p}_1, \ldots, \mathbf{x}_N + \mathbf{p}_N \\) thereby cueing the model to better learn sentence order.

 Instead of using fixed position embeddings, others (such as [Devlin et al.](https://huggingface.co/papers/1810.04805)) used learned positional encodings for which the positional embeddings

+$\mathbf{P}$ are learned during training.
 
 Sinusoidal and learned position embeddings used to be the predominant methods to encode sentence order into LLMs, but a couple of problems related to these positional encodings were found:
 
-  1. Sinusoidal and learned position embeddings are both absolute positional embeddings, *i.e.* encoding a unique embedding for each position id: \\( 0, \ldots, N \\) . As shown by [Huang et al.](https://huggingface.co/papers/2009.13658) and [Su et al.](https://huggingface.co/papers/2104.09864), absolute positional embeddings lead to poor LLM performance for long text inputs. For long text inputs, it is advantageous if the model learns the relative positional distance input tokens have to each other instead of their absolute position.
-  2. When using learned position embeddings, the LLM has to be trained on a fixed input length \\( N \\), which makes it difficult to extrapolate to an input length longer than what it was trained on.

While the required peak memory for the \\( \mathbf{QK}^T \\) matrix is significantly reduced, holding the key-value cache in memory can become very memory expensive for long input sequences or multi-turn chat. Remember that the key-value cache needs to store the key-value vectors for all previous input vectors \\( \mathbf{x}_i \text{, for } i \in \{1, \ldots, c - 1\} \\) for all self-attention layers and for all attention heads.

 Let's compute the number of float values that need to be stored in the key-value cache for the LLM `bigcode/octocoder` that we used before.
 The number of float values amounts to two times the sequence length times the number of attention heads times the attention head dimension and times the number of layers.

 [Multi-Query-Attention](https://huggingface.co/papers/1911.02150) was proposed in Noam Shazeer's *Fast Transformer Decoding: One Write-Head is All You Need* paper. As the title says, Noam found out that instead of using `n_head` key-value projections weights, one can use a single head-value projection weight pair that is shared across all attention heads without that the model's performance significantly degrades.
 
-> By using a single head-value projection weight pair, the key value vectors \\( \mathbf{k}_i, \mathbf{v}_i \\) have to be identical across all attention heads which in turn means that we only need to store 1 key-value projection pair in the cache instead of `n_head` ones.

 As most LLMs use between 20 and 100 attention heads, MQA significantly reduces the memory consumption of the key-value cache. For the LLM used in this notebook we could therefore reduce the required memory consumption from 15 GB to less than 400 MB at an input sequence length of 16000.
 
 In addition to memory savings, MQA also leads to improved computational efficiency as explained in the following.
-In auto-regressive decoding, large key-value vectors need to be reloaded, concatenated with the current key-value vector pair to be then fed into the \\( \mathbf{q}_c\mathbf{K}^T \\) computation at every step. For auto-regressive decoding, the required memory bandwidth for the constant reloading can become a serious time bottleneck. By reducing the size of the key-value vectors less memory needs to be accessed, thus reducing the memory bandwidth bottleneck. For more detail, please have a look at [Noam's paper](https://huggingface.co/papers/1911.02150).

-The important part to understand here is that reducing the number of key-value attention heads to 1 only makes sense if a key-value cache is used. The peak memory consumption of the model for a single forward pass without key-value cache stays unchanged as every attention head still has a unique query vector so that each attention head still has a different \\( \mathbf{QK}^T \\) matrix.

 [BART](https://huggingface.co/papers/1910.13461) is a sequence-to-sequence model that combines the pretraining objectives from BERT and GPT. It's pretrained by corrupting text in different ways like deleting words, shuffling sentences, or masking tokens and learning how to fix it. The encoder encodes the corrupted document and the corrupted text is fixed by the decoder. As it learns to recover the original text, BART gets really good at both understanding and generating language.

Our results demonstrate the feasibility of scaling models trained on raw bytes without a fixed vocabulary. Both training and inference efficiency improve due to dynamically selecting long patches when data is predictable, along with qualitative improvements on reasoning and long tail generalization. Overall, for fixed inference costs, BLT shows significantly better scaling than tokenization-based models, by simultaneously growing both patch and model size.*

+# Code World Model (CWM)
+
+## Overview
+
+The Code World Model (CWM) model was proposed in [CWM: An Open-Weights LLM for Research on Code
+Generation with World Models](https://ai.facebook.com/research/publications/cwm) by Meta FAIR CodeGen Team.
+CWM is an LLM for code generation and reasoning about code that has, in particular, been trained
+to better represent and reason about how code and commands affect the state of a program or system.
+Specifically, we mid-trained CWM on a large number of observation-action trajectories from Python
+execution traces and agentic interactions in containerized environments. We post-trained with
+extensive multi-task RL in verifiable coding, math, and multi-turn software engineering environments.
+
+The abstract from the paper is the following:
+
+> *We release Code World Model (CWM), a 32-billion-parameter open-weights LLM, to advance research
+on code generation with world models. To improve code understanding beyond what can be learned
+from training on static code alone, we mid-train CWM on a large amount of observation-action
+trajectories from Python interpreter and agentic Docker environments, and perform extensive multi-
+task reasoning RL in verifiable coding, math, and multi-turn software engineering environments. With
+CWM, we provide a strong testbed for researchers to explore the opportunities world modeling affords
+for improving code generation with reasoning and planning in computational environments. We
+present first steps of how world models can benefit agentic coding, enable step-by-step simulation of
+Python code execution, and show early results of how reasoning can benefit from the latter. CWM is
+a dense, decoder-only LLM trained with a context size of up to 131 k tokens. Independent of its world
+modeling capabilities, CWM offers strong performance on general coding and math tasks: it reaches
+pass@1 scores of 65.8 % on SWE-bench Verified (with test-time scaling), 68.9 % on LiveCodeBench,
+96.6 % on Math-500, and 76.0 % on AIME 2024. To support further research on code world modeling,
+we release model checkpoints after mid-training, SFT, and RL.*
+
+Tips:
+
+CWM requires a dedicated system prompt to function optimally during inference. Without proper prompt
+configuration, CWM's output quality may be significantly degraded. The following serves as the default
+system prompt for reasoning tasks. For agentic workflows, append the relevant tool specifications
+after this base prompt. Checkout the original code repository for more details.

+
+    Okay, I need to write a haiku about recursion in programming. Let's start by recalling what recursion is. Recursion is a programming technique where a function calls itself in its own definition, often used to solve problems that can be broken down into smaller, similar sub-problems.
+
+    A haiku is a three-line poem with a syllable count of 5-7-5. So, I need to capture the essence of recursion in a concise and poetic way. Let's think about the key elements of recursion: the function calling itself, the base case that stops the recursion, and the idea of breaking down problems into smaller parts.
+
+    Maybe I can use imagery related to mirrors or reflections, since recursion often involves a function reflecting or repeating itself. Alternatively, I could use natural imagery like a spiral or a tree, which suggests self-similar patterns.
+
+    Let me try to come up with some ideas. For example, "Function calls itself" could be a starting point. But how to make that into a haiku? Maybe something like:
+
+    Function calls itself
+    Base case stops the endless loop
+    Spiral of code
+
+    Hmm, that's a start. But maybe I can make it more poetic. Let's think about the idea of a function calling itself as a kind of infinite loop, but with a base case that stops it. That's like a spiral that unwinds at the center.
+
+    Another angle: recursion is often used for problems that have a recursive structure, like tree traversals or factorial calculations. Maybe I can use a natural image to represent that.
+
+    How about:
+
+    Branches split again
+    Leaves unfold in endless dance
+    Roots hold the base case
+
+    That's a bit more poetic. The branches splitting represent the recursive calls, the leaves unfolding could represent the processing of each sub-problem, and the roots holding the base case are what stops the recursion.
+
+    Alternatively, maybe something simpler:
+
+    Mirror within mirror
+    Reflections infinite deep
+    Base case breaks the glass
+
+    This uses the mirror metaphor to represent the function calling itself, with the base case being the point where the recursion stops, breaking the infinite reflection.
+
+    I think I like the mirror idea better. Let me refine that:
+
+    Mirror within mirror
+    Infinite reflections dance
+    Base case shatters glass
+
+    Yes, that seems to capture the idea of recursion well. The mirror represents the function calling itself, the infinite reflections are the recursive calls, and the base case shattering the glass is what stops the recursion.
+
+    Let me check the syllable count:
+
+    Mirror within mirror (5 syllables: Mir-ror-with-in-mir-ror)
+    Infinite reflections dance (7 syllables: In-fi-nite-ref-lec-tions-dance)
+    Base case shatters glass (5 syllables: Base-case-shat-ters-glass)
+
+    Yes, that fits the 5-7-5 structure. I think that's a good haiku about recursion.
+    </think>
+    Mirror within mirror
+    Infinite reflections dance
+    Base case shatters glass<|eot_id|>

 - The decoder of DETR updates the query embeddings in parallel. This is different from language models like GPT-2, which use autoregressive decoding instead of parallel. Hence, no causal attention mask is used.
 - DETR adds position embeddings to the hidden states at each self-attention and cross-attention layer before projecting to queries and keys. For the position embeddings of the image, one can choose between fixed sinusoidal or learned absolute position embeddings. By default, the parameter `position_embedding_type` of [`~transformers.DetrConfig`] is set to `"sine"`.
 - During training, the authors of DETR did find it helpful to use auxiliary losses in the decoder, especially to help the model output the correct number of objects of each class. If you set the parameter `auxiliary_loss` of [`~transformers.DetrConfig`] to `True`, then prediction feedforward neural networks and Hungarian losses are added after each decoder layer (with the FFNs sharing parameters).

 - [`~transformers.DetrForObjectDetection`] and [`~transformers.DetrForSegmentation`] can be initialized with any convolutional backbone available in the [timm library](https://github.com/rwightman/pytorch-image-models). Initializing with a MobileNet backbone for example can be done by setting the `backbone` attribute of [`~transformers.DetrConfig`] to `"tf_mobilenetv3_small_075"`, and then initializing the model with that config.
 - DETR resizes the input images such that the shortest side is at least a certain amount of pixels while the longest is at most 1333 pixels. At training time, scale augmentation is used such that the shortest side is randomly set to at least 480 and at most 800 pixels. At inference time, the shortest side is set to 800. One can use [`~transformers.DetrImageProcessor`] to prepare images (and optional annotations in COCO format) for the model. Due to this resizing, images in a batch can have different sizes. DETR solves this by padding images up to the largest size in a batch, and by creating a pixel mask that indicates which pixels are real/which are padding. Alternatively, one can also define a custom `collate_fn` in order to batch images together, using [`~transformers.DetrImageProcessor.pad_and_create_pixel_mask`].
 - The size of the images will determine the amount of memory being used, and will thus determine the `batch_size`. It is advised to use a batch size of 2 per GPU. See [this Github thread](https://github.com/facebookresearch/detr/issues/150) for more info.

@@ -33,6 +33,7 @@ The abstract from the paper is the following:
 *Transformer tends to overallocate attention to irrelevant context. In this work, we introduce Diff Transformer, which amplifies attention to the relevant context while canceling noise. Specifically, the differential attention mechanism calculates attention scores as the difference between two separate softmax attention maps. The subtraction cancels noise, promoting the emergence of sparse attention patterns. Experimental results on language modeling show that Diff Transformer outperforms Transformer in various settings of scaling up model size and training tokens. More intriguingly, it offers notable advantages in practical applications, such as long-context modeling, key information retrieval, hallucination mitigation, in-context learning, and reduction of activation outliers. By being less distracted by irrelevant context, Diff Transformer can mitigate hallucination in question answering and text summarization. For in-context learning, Diff Transformer not only enhances accuracy but is also more robust to order permutation, which was considered as a chronic robustness issue. The results position Diff Transformer as a highly effective and promising architecture to advance large language models.*

 ## Overview
 
+Both **GLM-4.6** and **GLM-4.5** language model use this class. The implementation in transformers does not include an MTP layer.
+
+### GLM-4.6
+
+Compared with GLM-4.5, **GLM-4.6**  brings several key improvements:
+
+* **Longer context window:** The context window has been expanded from 128K to 200K tokens, enabling the model to handle more complex agentic tasks.
+* **Superior coding performance:** The model achieves higher scores on code benchmarks and demonstrates better real-world performance in applications such as Claude Code、Cline、Roo Code and Kilo Code, including improvements in generating visually polished front-end pages.
+* **Advanced reasoning:** GLM-4.6 shows a clear improvement in reasoning performance and supports tool use during inference, leading to stronger overall capability.
+* **More capable agents:** GLM-4.6 exhibits stronger performance in tool using and search-based agents, and integrates more effectively within agent frameworks.
+* **Refined writing:** Better aligns with human preferences in style and readability, and performs more naturally in role-playing scenarios.
+
+We evaluated GLM-4.6 across eight public benchmarks covering agents, reasoning, and coding. Results show clear gains over GLM-4.5, with GLM-4.6 also holding competitive advantages over leading domestic and international models such as **DeepSeek-V3.1-Terminus** and **Claude Sonnet 4**.

+
+For more eval results, show cases, and technical details, please visit our [technical blog](https://z.ai/blog/glm-4.6).
+
+### GLM-4.5
+
 The [**GLM-4.5**](https://huggingface.co/papers/2508.06471) series models are foundation models designed for intelligent agents, MoE variants are documented here as Glm4Moe.
 
 GLM-4.5 has **355** billion total parameters with **32** billion active parameters, while GLM-4.5-Air adopts a more compact design with **106** billion total parameters and **12** billion active parameters. GLM-4.5 models unify reasoning, coding, and intelligent agent capabilities to meet the complex demands of intelligent agent applications.

Unlike with standard attention implementations where sinks can be added directly to attention scores, flex attention `score_mod` function operates on individual score elements rather than the full attention matrix. Therefore, attention sinks renormalization have to be applied after the flex attention computations by renormalizing the outputs using the log-sum-exp (LSE) values returned by flex attention.

 ## Overview
+
 The [Granite Speech](https://huggingface.co/papers/2505.08699) model ([blog post](https://www.ibm.com/new/announcements/ibm-granite-3-3-speech-recognition-refined-reasoning-rag-loras)) is a multimodal language model, consisting of a speech encoder, speech projector, large language model, and LoRA adapter(s). More details regarding each component for the current (Granite 3.2 Speech) model architecture may be found below.
 
 1. Speech Encoder: A [Conformer](https://huggingface.co/papers/2005.08100) encoder trained with Connectionist Temporal Classification (CTC) on character-level targets on ASR corpora. The encoder uses block-attention and self-conditioned CTC from the middle layer.
