A unified source of truth for LLM providers, models, pricing, and capabilities.

Accessible via Rust and Python.

Philosophy

Managing LLM provider configurations across multiple projects and languages is a pain. LLM Providers solves this by maintaining a single, curated JSON source of truth for:

• Model IDs & Names
• Context Windows & Max Output Tokens
• Pricing (Input/Output)
• Capabilities (Tool Support, Vision, etc.)

This data is embedded at compile-time into a Rust crate for zero-latency access and exposed to Python via high-performance bindings.

Features

• 🚀 Zero-Latency: Data is compiled into the binary; no runtime I/O or API calls.
• 🦀 Rust Native: Type-safe structs (Provider, Model) for robust development.
• 🐍 Python Ready: Seamless integration via pip install llm-providers-list.
• 🔄 Unified Schema: Consistent data structure across all providers (OpenAI, Anthropic, DeepSeek, etc.).
• 📦 Rich Metadata: Includes pricing, context length, and tool support flags.

Installation

Rust

Add this to your Cargo.toml:

[dependencies]
llm_providers = "0.6"

Python

Install via pip (once published) or build from source:

# From PyPI (Coming Soon)
pip install llm-providers-list

# Build from source (requires maturin)
pip install maturin
maturin develop -m py/Cargo.toml

Usage

Rust

use llm_providers::{get_providers_data, list_providers, list_endpoints, get_endpoint, get_model};

fn main() {
    // 1. List all provider family IDs
    let families = list_providers();
    println!("Families: {:?}", families);

    // 2. List all endpoint IDs (for direct configuration)
    let endpoints = list_endpoints();
    println!("Endpoints: {:?}", endpoints);

    // 3. Get endpoint details by ID
    if let Some((family_id, ep)) = get_endpoint("moonshot:global") {
        println!("Family: {}, Base URL: {}, Region: {}", family_id, ep.base_url, ep.region);
    }

    // 4. Get specific model details
    if let Some(model) = get_model("openai", "gpt-4o") {
        println!("Model: {} (Price: ${}/1M input)", model.name, model.input_price);
    }
}

Python

import llm_providers_list

# 1. List all provider families
print(llm_providers_list.list_providers())
# Output: ['aliyun', 'anthropic', 'deepseek', 'openai', ...]

# 2. List all endpoint IDs (for direct configuration)
print(llm_providers_list.list_endpoints())
# Output: ['aliyun:cn', 'anthropic:global', 'moonshot:cn', 'moonshot:global', ...]

# 3. Get endpoint details by ID
family_id, ep = llm_providers_list.get_endpoint("moonshot:global")
print(f"Family: {family_id}, Base URL: {ep.base_url}, Region: {ep.region}")

# 4. Get specific model details
model = llm_providers_list.get_model("openai", "gpt-4o")
print(f"Model: {model.name}, Price: ${model.input_price}/1M tokens")

Advanced Usage

Filtering Models

You can filter models by region, capabilities (tools), or context length.

Rust

use llm_providers::{filter_models, ModelFilter};

let cn_models = filter_models(ModelFilter {
    region: Some("cn".to_string()),
    supports_tools: Some(true),
    ..Default::default()
});

for (provider_id, model) in cn_models {
    println!("{}: {}", provider_id, model.name);
}

Python

import llm_providers_list

# Find all models in CN region that support tools
cn_tools_models = llm_providers_list.filter_models(
    region="cn", 
    supports_tools=True
)

for provider_id, model in cn_tools_models:
    print(f"[{provider_id}] {model.name}")

Data Structure

The registry is embedded in the crate as Rust static data (PHF maps, no runtime JSON parsing).

• Provider Family: Top-level grouping (e.g., openai, moonshot). Models are defined once per family.
• Endpoint: Regional API entry point under a family. Each endpoint has its own base_url, region, and price_currency.
• Region: cn (China), global (International), us, eu, etc.
• Price Currency: USD or CNY, defined at the endpoint level.

Endpoint ID Format (v0.6+)

Endpoint IDs are now composite to avoid ambiguity across providers:

• "{provider_id}:{endpoint_key}" (recommended)
• Example: moonshot:global, zhipu:cn

See docs/providers.md for a full list of endpoint IDs.
