+# DeepSeek-R1-0528-AWQ
+AWQ of DeepSeek R1 0528.
+
+Quantized by [Eric Hartford](https://huggingface.co/ehartford) and [v2ray](https://huggingface.co/v2ray).
+
+Compute for this quant was generously sponsored by [Hot Aisle](https://hotaisle.xyz/). Thank you for supporting the community!
+
+This quant modified some of the model code to fix an overflow issue when using float16.
+
+To serve using vLLM with 8x 80GB GPUs, use the following command:
+```sh
+VLLM_USE_V1=0 VLLM_WORKER_MULTIPROC_METHOD=spawn VLLM_MARLIN_USE_ATOMIC_ADD=1 python -m vllm.entrypoints.openai.api_server --host 0.0.0.0 --port 12345 --max-model-len 65536 --max-seq-len-to-capture 65536 --enable-chunked-prefill --enable-prefix-caching --trust-remote-code --tensor-parallel-size 8 --gpu-memory-utilization 0.95 --served-model-name deepseek-chat --model cognitivecomputations/DeepSeek-V3-0324-AWQ
+```
+You can download the wheel I built for PyTorch 2.6, Python 3.12 by clicking [here](https://huggingface.co/x2ray/wheels/resolve/main/vllm-0.8.3.dev250%2Bg10afedcfd.cu128-cp312-cp312-linux_x86_64.whl), the benchmark below was done with this wheel, it contains [2 PR merges](https://github.com/vllm-project/vllm/issues?q=is%3Apr+is%3Aopen+author%3Ajinzhen-lin) and an unoptimized FlashMLA (still faster than Triton) for A100 which boosted performance a lot. The vLLM repo which contained A100 FlashMLA can be found at [LagPixelLOL/vllm@sm80_flashmla](https://github.com/LagPixelLOL/vllm/tree/sm80_flashmla), which is a fork of [vllm-project/vllm](https://github.com/vllm-project/vllm). The A100 FlashMLA it used is based on [LagPixelLOL/FlashMLA@vllm](https://github.com/LagPixelLOL/FlashMLA/tree/vllm), which is a fork of [pzhao-eng/FlashMLA](https://github.com/pzhao-eng/FlashMLA).

+## TPS Per Request
+| GPU \ Batch Input Output | B: 1 I: 2 O: 2K | B: 32 I: 4K O: 256 | B: 1 I: 63K O: 2K | Prefill |
+|:-:|:-:|:-:|:-:|:-:|
+| **8x H100/H200** | 61.5 | 30.1 | 54.3 | 4732.2 |
+| **4x H200** | 58.4 | 19.8 | 53.7 | 2653.1 |
+| **8x A100 80GB** | 46.8 | 12.8 | 30.4 | 2442.4 |
+| **8x L40S** | 46.3 | OOM | OOM | 688.5 |
+
+Note:
+- The A100 config uses an unoptimized FlashMLA implementation, which is only superior than Triton during high context inference, it would be faster if it's optimized.
+- The L40S config doesn't support FlashMLA, thus the Triton implementation is used, this makes it extremely slow with high context. But the L40S doesn't have much VRAM, so it can't really have that much context anyway, and it also doesn't have the fast GPU to GPU interconnection bandwidth, making it even slower. It is not recommended to serve with this config, as you must limit the context to <= 4096, `--gpu-memory-utilization` to 0.98, and `--max-num-seqs` to 4.
+- All types of GPU used during benchmark are SXM form factor except L40S.
+- Inference speed will be better than FP8 at low batch size but worse than FP8 at high batch size, this is the nature of low bit quantization.
+- vLLM supports MLA for AWQ now, you can run this model with full context length on just 8x 80GB GPUs.

+            it.
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.

+            [What are input IDs?](../glossary#input-ids)
+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.

+
+            If `past_key_values` is used, optionally only the last `input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
+            and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more
+            information on the default strategy.
+
+            - 1 indicates the head is **not masked**,

+        position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
+            config.n_positions - 1]`.
+
+            [What are position IDs?](../glossary#position-ids)
+        past_key_values (`Cache` or `tuple(tuple(torch.FloatTensor))`, *optional*):
+            Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
+            returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
+
+            Two formats are allowed:
+            - a [`~cache_utils.Cache`] instance;
+            - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+            shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+            cache format.
+
+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+            legacy cache format will be returned.
+
+            If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+            have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+            of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
