Llama 2 7B Chat ggml

From: https://huggingface.co/meta-llama/Llama-2-7b-chat-hf

---

Original llama.cpp quant methods: q4_0, q4_1, q5_0, q5_1, q8_0

Quantized using an older version of llama.cpp and compatible with llama.cpp from May 19, commit 2d5db48.

k-quant methods: q2_K, q3_K_S, q3_K_M, q3_K_L, q4_K_S, q4_K_M, q5_K_S, q6_K

Quantization methods compatible with latest llama.cpp from June 6, commit 2d43387.

llama-2-7b-chat.ggmlv3.q3_K_M.bin	q3_K_M	3	3.28 GB	5.78 GB	New k-quant method. Uses GGML_TYPE_Q4_K for the attention.wv, attention.wo, and feed_forward.w2 tensors, else GGML_TYPE_Q3_K
llama-2-7b-chat.ggmlv3.q3_K_S.bin	q3_K_S	3	2.95 GB	5.45 GB	New k-quant method. Uses GGML_TYPE_Q3_K for all tensors
llama-2-7b-chat.ggmlv3.q4_0.bin	q4_0	4	3.79 GB	6.29 GB	Original quant method, 4-bit.
llama-2-7b-chat.ggmlv3.q4_1.bin	q4_1	4	4.21 GB	6.71 GB	Original quant method, 4-bit. Higher accuracy than q4_0 but not as high as q5_0. However has quicker inference than q5 models.
llama-2-7b-chat.ggmlv3.q4_K_M.bin	q4_K_M	4	4.08 GB	6.58 GB	New k-quant method. Uses GGML_TYPE_Q6_K for half of the attention.wv and feed_forward.w2 tensors, else GGML_TYPE_Q4_K
llama-2-7b-chat.ggmlv3.q4_K_S.bin	q4_K_S	4	3.83 GB	6.33 GB	New k-quant method. Uses GGML_TYPE_Q4_K for all tensors
llama-2-7b-chat.ggmlv3.q5_0.bin	q5_0	5	4.63 GB	7.13 GB	Original quant method, 5-bit. Higher accuracy, higher resource usage and slower inference.
llama-2-7b-chat.ggmlv3.q5_1.bin	q5_1	5	5.06 GB	7.56 GB	Original quant method, 5-bit. Even higher accuracy, resource usage and slower inference.
llama-2-7b-chat.ggmlv3.q5_K_M.bin	q5_K_M	5	4.78 GB	7.28 GB	New k-quant method. Uses GGML_TYPE_Q6_K for half of the attention.wv and feed_forward.w2 tensors, else GGML_TYPE_Q5_K

llama-2-7b-chat.ggmlv3.q6_K.bin	q6_K	6	5.53 GB	8.03 GB	New k-quant method. Uses GGML_TYPE_Q8_K for all tensors - 6-bit quantization
llama-2-7b-chat.ggmlv3.q8_0.bin	q8_0	8	7.16 GB	9.66 GB	Original quant method, 8-bit. Almost indistinguishable from float16. High resource use and slow. Not recommended for most users.
