Maybe risky, some lack of thread safety: https://github.com/encode/httpx/discussions/3043, so disabled :param prompt_type: type of prompt, usually matched to fine-tuned model or plain for foundational model :param prompt_dict: If prompt_type=custom, then expects (some) items returned by get_prompt(..., return_dict=True) :param system_prompt: Universal system prompt to use if model supports, like LLaMa2, regardless of prompt_type definition. Useful for langchain case to control behavior, or OpenAI and Replicate. If None, 'None', or 'auto', then for LLaMa or other models that internally have system_prompt, will use default for each model If '', then no system prompt (no empty template given to model either, just no system part added at all) If some string not in ['None', 'auto'], then use that as system prompt Default is '', no system_prompt, because often it hurts performance/accuracy :param allow_chat_system_prompt: Whether to use conversation_history to pre-append system prompt :param llamacpp_path: Location to store downloaded gguf or load list of models from Note HF models go into hf cache folder, and gpt4all models go into their own cache folder Can override with ENV LLAMACPP_PATH :param llamacpp_dict: n_gpu_layers: for llama.cpp based models, number of GPU layers to offload (default is all by using large value) use_mlock: when using `llama.cpp` based CPU models, for computers with low system RAM or slow CPUs, recommended False n_batch: Can make smaller to 128 for slower low-memory CPU systems n_gqa: Required to be 8 for LLaMa 70B ... etc. anything that could be passed to llama.cpp or GPT4All models e.g. python generate.py --base_model='llama' --prompt_type=llama2 --score_model=None --langchain_mode='UserData' --user_path=user_path --llamacpp_dict="{'n_gpu_layers':25,'n_batch':128}" :param model_path_llama: model path or URL (for auto-download) :param model_name_gptj: model path or URL (for auto-download) :param model_name_gpt4all_llama: model path or URL (for auto-download) :param model_name_exllama_if_no_config: exllama model's full path for model, tokenizer, generator for use when no HuggingFace config :param exllama_dict for setting various things for Exllama class E.g. compress_pos_emb, set_auto_map, gpu_peer_fix, alpha_value, matmul_recons_thd, fused_mlp_thd sdp_thd fused_attn matmul_fused_remap rmsnorm_no_half2 rope_no_half2 matmul_no_half2 silu_no_half2 concurrent_streams E.g. to set memory to be split across 2 GPUs, use --exllama_dict="{'set_auto_map':20,20}" :param gptq_dict: Choices for AutoGPTQ, e.g. one can change defaults to these non-defaults: inject_fused_attention=False disable_exllama=True use_triton=True :param attention_sinks: Whether to enable attention sinks. :param sink_dict: dict of options for attention sinks E.g. {'window_length': 1024, 'num_sink_tokens': 4} Default is window length same size as max_input_tokens (max_seq_len if max_input_tokens not set) :param hf_model_dict: dict of options for HF models using transformers :param truncation_generation: Whether (for torch) to terminate generation once reach context length of model. For some models, perplexity becomes critically large beyond context For other models like Mistral, one can generate beyond max_seq_len set to 4096 or 8192 without issue, since based upon 32k embeddings codellama can also generate beyond its 16k context length So default is off, but for simpler/older models True may be wise to avoid bad generations :param model_lock: Lock models to specific combinations, for ease of use and extending to many models Only used if gradio = True List of dicts, each dict has base_model, tokenizer_base_model, lora_weights, inference_server, prompt_type, and prompt_dict If all models have same prompt_type, and prompt_dict, can still specify that once in CLI outside model_lock as default for dict Can specify model_lock instead of those items on CLI As with CLI itself, base_model can infer prompt_type and prompt_dict if in prompter.py. Also, tokenizer_base_model and lora_weights are optional. Also, inference_server is optional if loading model from local system. All models provided will automatically appear in compare model mode Model loading-unloading and related choices will be disabled. Model/lora/server adding will be disabled :param model_lock_columns: How many columns to show if locking models (and so showing all at once) If None, then defaults to up to 3 if -1, then all goes into 1 row Maximum value is 4 due to non-dynamic gradio rendering elements :param model_lock_layout_based_upon_initial_visible: Whether to base any layout upon visible models (True) or upon all possible models. gradio does not allow dynamic objects, so all layouts are preset, and these are two reasonable options. False is best when there are many models and user excludes middle ones as being visible. :param fail_if_cannot_connect: if doing model locking (e.g. with many models), fail if True. Otherwise ignore. Useful when many endpoints and want to just see what works, but still have to wait for timeout. :param temperature: generation temperature :param top_p: generation top_p :param top_k: generation top_k :param penalty_alpha: penalty_alpha>0 and top_k>1 enables contrastive search (not all models support) :param num_beams: generation number of beams :param repetition_penalty: generation repetition penalty :param num_return_sequences: generation number of sequences (1 forced for chat) :param do_sample: generation sample :param max_new_tokens: generation max new tokens :param min_new_tokens: generation min tokens :param early_stopping: generation early stopping :param max_time: maximum time to allow for generation :param memory_restriction_level: 0 = no restriction to tokens or model, 1 = some restrictions on token 2 = HF like restriction 3 = very low memory case :param debug: enable debug mode :param save_dir: directory chat data is saved to :param local_files_only: whether to only use local files instead of doing to HF for models :param resume_download: whether to resume downloads from HF for models :param use_auth_token: whether to use HF auth token (requires CLI did huggingface-cli login before) :param trust_remote_code: whether to use trust any code needed for HF model :param rope_scaling: For HF transformers model: scaling for rope-based models.

Note: Some things always disabled include HF telemetry, gradio telemetry, chromadb posthog that involve uploading. This option further disables google fonts for downloading, which is less intrusive than uploading, but still required in air-gapped case. The fonts don't look as nice as google fonts, but ensure full offline behavior. Also set --share=False to avoid sharing a gradio live link. :param server_name: IP to use. In linux 0.0.0.0 is good choice so exposed to outside host, else for only local use 127.0.0.1.

None: auto mode, check if langchain package exists, at least do LLM if so, else Disabled If not passed, then chosen to be first langchain_modes, else langchain_mode->Disabled is set if no langchain_modes either WARNING: wiki_full requires extra data processing via read_wiki_full.py and requires really good workstation to generate db, unless already present. :param user_path: user path to glob from to generate db for vector search, for 'UserData' langchain mode. If already have db, any new/changed files are added automatically if path set, does not have to be same path used for prior db sources :param langchain_modes: dbs to generate at launch to be ready for LLM Apart from additional user-defined collections, can include ['wiki', 'wiki_full', 'UserData', 'MyData', 'github h2oGPT', 'DriverlessAI docs'] But wiki_full is expensive and requires preparation To allow personal space only live in session, add 'MyData' to list Default: If only want to consume local files, e.g. prepared by make_db.py, only include ['UserData'] If have own user modes, need to add these here or add in UI. :param langchain_mode_paths: dict of langchain_mode keys and disk path values to use for source of documents E.g. "{'UserData2': 'userpath2'}" A disk path be None, e.g. --langchain_mode_paths="{'UserData2': None}" even if existing DB, to avoid new documents being added from that path, source links that are on disk still work. If `--user_path` was passed, that path is used for 'UserData' instead of the value in this dict :param langchain_mode_types: dict of langchain_mode keys and database types E.g. python generate.py --base_model=llama --langchain_modes=['TestData'] --langchain_mode_types="{'TestData':'shared'}" The type is attempted to be inferred if directory already exists, then don't have to pass this :param detect_user_path_changes_every_query: whether to detect if any files changed or added every similarity search (by file hashes).

Summarize is a "map reduce" and extraction is "map". That is, map returns a text output (roughly) per input item, while reduce reduces all maps down to single text output. The "roughly" refers to fact that if one has docs_token_handling='split_or_merge' then we split or merge chunks, so you will get a map for some optimal-sized chunks given the model size. If you choose docs_token_handling='chunk', then you get back a map for each chunk you give, but you should ensure the model token limit is not exceeded yourself. Summarize is useful when wanting to reduce down to single text, while Extract is useful when want to operate the prompt on blocks of data and get back a result per block. :param langchain_agents: Which agents to use 'search': Use Web Search as context for LLM response, e.g. SERP if have SERPAPI_API_KEY in env :param force_langchain_evaluate: Whether to force langchain LLM use even if not doing langchain, mostly for testing. :param visible_langchain_actions: Which actions to allow :param visible_langchain_agents: Which agents to allow :param document_subset: Default document choice when taking subset of collection :param document_choice: Chosen document(s) by internal name, 'All' means use all docs :param document_source_substrings: substrings in list to search in source names in metadata for chroma dbs :param document_source_substrings_op: 'and or 'or' for source search words :param document_content_substrings: substrings in list to search in content for chroma dbs :param document_content_substrings_op: 'and or 'or' for content search words :param use_llm_if_no_docs: Whether to use LLM even if no documents, when langchain_mode=UserData or MyData or custom :param load_db_if_exists: Whether to load chroma db if exists or re-generate db :param keep_sources_in_context: Whether to keep url sources in context, not helpful usually :param db_type: 'faiss' for in-memory 'chroma' (for chroma >= 0.4) 'chroma_old' (for chroma < 0.4) -- recommended for large collections 'weaviate' for persisted on disk :param use_openai_embedding: Whether to use OpenAI embeddings for vector db :param use_openai_model: Whether to use OpenAI model for use with vector db :param hf_embedding_model: Which HF embedding model to use for vector db Default is instructor-large with 768 parameters per embedding if have GPUs, else all-MiniLM-L6-v2 if no GPUs Can also choose simpler model with 384 parameters per embedding: "sentence-transformers/all-MiniLM-L6-v2" Can also choose even better embedding with 1024 parameters: 'hkunlp/instructor-xl' We support automatically changing of embeddings for chroma, with a backup of db made if this is done :param migrate_embedding_model: whether to use hf_embedding_model embedding even if database already had an embedding set. used to migrate all embeddings to a new one, but will take time to re-embed.

'best_first': Order by score so score is worst match near prompt 'best_near_prompt' or 'reverse_sort' : reverse docs order so most relevant is closest to question. Best choice for sufficiently smart model, and truncation occurs for oldest context, so best then too. But smaller 6_9 models fail to use newest context and can get stuck on old information.
