       --sharded <SHARDED>
           Whether to shard the model across multiple GPUs By default text-generation-inference will use all available GPUs to run the model. Setting it to `false` deactivates `num_shard`

           The number of shards to use if you don't want to use all GPUs on a given machine. You can use `CUDA_VISIBLE_DEVICES=0,1 text-generation-launcher... --num_shard 2` and `CUDA_VISIBLE_DEVICES=2,3 text-generation-launcher... --num_shard 2` to launch 2 copies with 2 shard each on a given machine with 4 GPUs for instance

+## TRUST_REMOTE_CODE
+```shell
       --trust-remote-code
           Whether you want to execute hub modelling code. Explicitly passing a `revision` is encouraged when loading a model with custom code to ensure no malicious code has been contributed in a newer revision

+```
+## MAX_CONCURRENT_REQUESTS
+```shell
       --max-concurrent-requests <MAX_CONCURRENT_REQUESTS>
           The maximum amount of concurrent requests for this particular deployment. Having a low limit will refuse clients requests instead of having them wait for too long and is usually good to handle backpressure correctly

           [default: 128]
 
+```
+## MAX_BEST_OF
+```shell
       --max-best-of <MAX_BEST_OF>
           This is the maximum allowed value for clients to set `best_of`. Best of makes `n` generations at the same time, and return the best in terms of overall log probability over the entire generated sequence
 
           [env: MAX_BEST_OF=]
           [default: 2]
 
+```
+## MAX_STOP_SEQUENCES
+```shell
       --max-stop-sequences <MAX_STOP_SEQUENCES>
           This is the maximum allowed value for clients to set `stop_sequences`. Stop sequences are used to allow the model to stop on more than just the EOS token, and enable more complex "prompting" where users can preprompt the model in a specific way and define their "own" stop token aligned with their prompt
 
           [env: MAX_STOP_SEQUENCES=]

+## MAX_TOP_N_TOKENS
+```shell
       --max-top-n-tokens <MAX_TOP_N_TOKENS>
           This is the maximum allowed value for clients to set `top_n_tokens`. `top_n_tokens is used to return information about the the `n` most likely tokens at each generation step, instead of just the sampled token. This information can be used for downstream tasks like for classification or ranking

+## MAX_INPUT_LENGTH
+```shell
       --max-input-length <MAX_INPUT_LENGTH>
           This is the maximum allowed input length (expressed in number of tokens) for users. The larger this value, the longer prompt users can send which can impact the overall memory required to handle the load. Please note that some models have a finite range of sequence they can handle

+## MAX_TOTAL_TOKENS
+```shell
       --max-total-tokens <MAX_TOTAL_TOKENS>
           This is the most important value to set as it defines the "memory budget" of running clients requests. Clients will send input sequences and ask to generate `max_new_tokens` on top. with a value of `1512` users can send either a prompt of `1000` and ask for `512` new tokens, or send a prompt of `1` and ask for `1511` max_new_tokens. The larger this value, the larger amount each request will be in your RAM and the less effective batching can be

+## WAITING_SERVED_RATIO
+```shell
       --waiting-served-ratio <WAITING_SERVED_RATIO>
           This represents the ratio of waiting queries vs running queries where you want to start considering pausing the running queries to include the waiting ones into the same batch. `waiting_served_ratio=1.2` Means when 12 queries are waiting and there's only 10 queries left in the current batch we check if we can fit those 12 waiting queries into the batching strategy, and if yes, then batching happens delaying the 10 running queries by a `prefill` run.
