llm_client 0.0.7

//! # llm_client: The Easiest Rust Interface for Local LLMs
//! [![API Documentation](https://docs.rs/llm_client/badge.svg)](https://docs.rs/llm_client)
//!
//! The llm_client crate is a workspace member of the [llm_client](https://github.com/ShelbyJenkins/llm_client) project.
//!
//!
//! Add to your Cargo.toml:
//! ```toml
//! # For Mac (CPU and GPU), windows (CPU and CUDA), or linux (CPU and CUDA)
//! llm_client="*"
//! ```
//!
//! This will download and build [llama.cpp](https://github.com/ggerganov/llama.cpp/blob/master/docs/build.md).
//! See [build.md](../docs/build.md) for other features and backends like mistral.rs.
//!
//! ```rust
//! use Llmclient::prelude::*;
//! let llm_client = LlmClient::llama_cpp()
//!     .mistral7b_instruct_v0_3() // Uses a preset model
//!     .init() // Downloads model from hugging face and starts the inference interface
//!     .await?;
//! ```
//!
//! Several of the most common models are available as presets. Loading from local models is also fully supported.
//! See [models.md](./docs/models.md) for more information.
//!
//! # An Interface for Deterministic Signals from Probabilistic LLM Vibes
//!
//! ## Reasoning with Primitive Outcomes
//!
//! A constraint enforced CoT process for reasoning. First, we get the LLM to 'justify' an answer in plain english.
//! This allows the LLM to 'think' by outputting the stream of tokens required to come to an answer. Then we take
//! that 'justification', and prompt the LLM to parse it for the answer.
//! See [the workflow for implementation details](./src/workflows/reason/one_round.rs).
//!
//! - Currently supporting returning booleans, u32s, and strings from a list of options
//! - Can be 'None' when ran with `return_optional_primitive()`
//!
//! ```rust
//! // boolean outcome
//! let reason_request = llm_client.reason().boolean();
//! reason_request
//!     .instructions()
//!     .set_content("Does this email subject indicate that the email is spam?");
//! reason_request
//!     .supporting_material()
//!     .set_content("You'll never believe these low, low prices 💲💲💲!!!");
//! let res: bool = reason_request.return_primitive().await.unwrap();
//! assert_eq!(res, true);
//!
//! // u32 outcome
//! let reason_request = llm_client.reason().integer();
//! reason_request.primitive.lower_bound(0).upper_bound(10000);
//! reason_request
//!     .instructions()
//!     .set_content("How many times is the word 'llm' mentioned in these comments?");
//! reason_request
//!     .supporting_material()
//!     .set_content(hacker_news_comment_section);
//! // Can be None
//! let response: Option<u32> = reason_request.return_optional_primitive().await.unwrap();
//! assert!(res > Some(9000));
//!
//! // string from a list of options outcome
//! let mut reason_request = llm_client.reason().exact_string();
//! reason_request
//!     .instructions()
//!     .set_content("Based on this readme, what is the name of the creator of this project?");
//! reason_request
//!     .supporting_material()
//!     .set_content(llm_client_readme);
//! reason_request
//!     .primitive
//!     .add_strings_to_allowed(&["shelby", "jack", "camacho", "john"]);
//! let response: String = reason_request.return_primitive().await.unwrap();
//! assert_eq!(res, "shelby");
//! ```
//!
//! See [the reason example for more](./examples/reason.rs)
//!
//! ## Decisions with N number of Votes Across a Temperature Gradient
//!
//! Uses the same process as above N number of times where N is the number of times the process must be repeated
//! to reach a consensus. We dynamically alter the temperature to ensure an accurate consensus.
//! See [the workflow for implementation details](./src/workflows/reason/decision.rs).
//!
//! - Supports primitives that implement the reasoning trait
//! - The consensus vote count can be set with `best_of_n_votes()`
//! - By default `dynamic_temperture` is enabled, and each 'vote' increases across a gradient
//!
//! ```rust
//! // An integer decision request
//! let decision_request = llm_client.reason().integer().decision();
//! decision_request.best_of_n_votes(5);
//! decision_request
//!     .instructions()
//!     .set_content("How many fingers do you have?");
//! let response = decision_request.return_primitive().await.unwrap();
//! assert_eq!(response, 5);
//! ```
//!
//! See [the decision example for more](./examples/decision.rs)
//!
//! ## Structured Outputs and NLP
//!
//! - Data extraction, summarization, and semantic splitting on text
//! - Currently implemented NLP workflows are url extraction
//!
//! See [the extract_urls example](./examples/extract_urls.rs)
//!
//! ## Basic Primitives
//!
//! A generation where the output is constrained to one of the defined primitive types.
//! See [the currently implemented primitive types](./src/primitives/mod.rs).
//! These are used in other workflows, but only some are used as the output for specific workflows like reason and decision.
//!
//! - These are fairly easy to add, so feel free to open an issue if you'd like one added
//!
//! See [the basic_primitive example](./examples/basic_primitive.rs)
//!
//! ## API LLMs
//!
//! - Basic support for API based LLMs. Currently, anthropic, openai, perplexity
//! - Perplexity does not *currently* return documents, but it does create its responses from live data
//!
//! ```rust
//! let llm_client = LlmClient::perplexity().sonar_large().init();
//! let mut basic_completion = llm_client.basic_completion();
//! basic_completion
//!     .prompt()
//!     .add_user_message()
//!     .set_content("Can you help me use the llm_client rust crate? I'm having trouble getting cuda to work.");
//! let response = basic_completion.run().await?;
//! ```
//!
//! See [the basic_completion example](./examples/basic_completion.rs)
//!
//! ## Configuring Requests
//!
//! - All requests and workflows implement the `RequestConfigTrait` which gives access to the parameters sent to the LLM
//! - These settings are normalized across both local and API requests
//!
//! ```rust
//! let llm_client = LlmClient::llama_cpp()
//!     .available_vram(48)
//!     .mistral7b_instruct_v0_3()
//!     .init()
//!     .await?;
//!
//! let basic_completion = llm_client.basic_completion();
//!
//! basic_completion
//!     .temperature(1.5)
//!     .frequency_penalty(0.9)
//!     .max_tokens(200);
//! ```
//!
//! See [See all the settings here](../llm_interface/src/requests/req_components.rs)
