 These files are GGML format model files for [LmSys' Long Chat 7B](https://huggingface.co/lmsys/longchat-7b-16k).
 
-GGML files are for CPU + GPU inference using [llama.cpp](https://github.com/ggerganov/llama.cpp) and libraries and UIs which support this format, such as:
-* [text-generation-webui](https://github.com/oobabooga/text-generation-webui)
-* [KoboldCpp](https://github.com/LostRuins/koboldcpp)
-* [LoLLMS Web UI](https://github.com/ParisNeo/lollms-webui)
-* [llama-cpp-python](https://github.com/abetlen/llama-cpp-python)
-* [ctransformers](https://github.com/marella/ctransformers)
+These are RoPE GGMLs with an increased context length. RoPE - Rotated Positional Encoding - expands context beyond what was originally possible for a model. It was discovered and developed by [kaiokendev](https://huggingface.co/kaiokendev).
+
+In order to use the increased context length, you can presently use:
+* [KoboldCpp](https://github.com/LostRuins/koboldcpp) - [release 1.33](https://github.com/LostRuins/koboldcpp/releases/tag/v1.33) or later.
+
+Support is also expected to come to llama.cpp, however work is still being done to find the optimal implementation.
+
+To use the increased context with KoboldCpp, use `--contextsize` to set the desired context, eg `--contextsize 4096` or `--contextsize 8192` or `--contextsize 16384`.
+
+**NOTE**: Increased context length is an area seeing rapid developments and improvements. It is quite possible that these models may be superseded by new developments in the coming days. If that's the case, I will remove them, or update this README as appropriate.

 ## Compatibility
 
-### Original llama.cpp quant methods: `q4_0, q4_1, q5_0, q5_1, q8_0`
-
-I have quantized these 'original' quantisation methods using an older version of llama.cpp so that they remain compatible with llama.cpp as of May 19th, commit `2d5db48`.
-
-These are guaranteed to be compatbile with any UIs, tools and libraries released since late May.
+These GGMLs will work with any llama.cpp-compatible GGML client that supports k-quants.
 
-### New 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`
-
-These new quantisation methods are compatible with llama.cpp as of June 6th, commit `2d43387`.
-
-They are now also compatible with recent releases of text-generation-webui, KoboldCpp, llama-cpp-python and ctransformers. Other tools and libraries may or may not be compatible - check their documentation if in doubt.
+However the increased context length won't work without specific support. See the note in the introduction for details on using increased context.

+On Linux I use the following command line to launch the KoboldCpp UI with OpenCL aceleration and a context size of 4096:
 
 ```
-./main -t 10 -ngl 32 -m longchat-7b-16k.ggmlv3.q5_0.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "### Instruction: Write a story about llamas\n### Response:"

 ```
-If you're able to use full GPU offloading, you should use `-t 1` to get best performance.
-
-If not able to fully offload to GPU, you should use more cores. Change `-t 10` to the number of physical CPU cores you have, or a lower number depending on what gives best performance.
-
-Change `-ngl 32` to the number of layers to offload to GPU. Remove it if you don't have GPU acceleration.

-If you want to have a chat-style conversation, replace the `-p <PROMPT>` argument with `-i -ins`
 
-## How to run in `text-generation-webui`
+Change `--gpulayers 100` to the number of layers you want/are able to offload to the GPU. Remove it if you don't have GPU acceleration.
 
-Further instructions here: [text-generation-webui/docs/llama.cpp-models.md](https://github.com/oobabooga/text-generation-webui/blob/main/docs/llama.cpp-models.md).
+For OpenCL acceleration, change `--usecublas` to `--useclblast 0 0`. You may need to change the second `0` to `1` if you have both an iGPU and a discrete GPU.
