llm-kit-pro 0.1.2

A unified toolkit for working with multiple LLM providers

llm-kit

llm-kit is a unified, async-first Python toolkit for interacting with multiple Large Language Model (LLM) providers through a consistent, provider-agnostic API.

It supports:

• Multiple LLM providers (OpenAI, Gemini, Anthropic, etc.)
• Text and structured JSON generation
• Multimodal inputs (PDFs, images, text files)
• Clean abstractions and strong typing

---

✨ Core Ideas

1. Outputs are explicit

LLMs generate outputs, not OCR results.

llm-kit exposes two primary operations:

• generate_text → free-form text
• generate_json → structured, schema-driven output

2. Inputs can be text and/or files

Files (PDFs, images, etc.) are first-class inputs and can be passed directly to generation methods.

OCR and file parsing are treated as provider implementation details.

📦 Installation

pip install llm-kit

Optional provider support (example):

pip install llm-kit[openai]
pip install llm-kit[gemini]

---

🚀 Quick Start

Text-only generation

text = await llm.generate_text(
    prompt="Explain what power factor is in simple terms"
)

---

Text generation with a file (PDF, image, etc.)

from llm_kit.core import LLMFile

pdf = LLMFile(
    content=pdf_bytes,
    mime_type="application/pdf",
    filename="bill.pdf",
)

summary = await llm.generate_text(
    prompt="Summarize this electricity bill",
    files=[pdf],
)

---

Structured JSON extraction

schema = {
    "type": "object",
    "properties": {
        "consumer_name": {"type": "string"},
        "bill_amount": {"type": "number"},
        "due_date": {"type": "string"},
    },
    "required": ["consumer_name", "bill_amount"],
}

data = await llm.generate_json(
    prompt="Extract billing details from this document",
    schema=schema,
    files=[pdf],
)

---

🧠 Design Philosophy

• Provider-agnostic: No OpenAI/Gemini specifics in the public API
• Async-first: Built for modern Python backends
• Composable: Easy to plug into pipelines (FastAPI, background jobs, ETL)
• Explicit contracts: Clear separation of inputs, outputs, and providers

---

🧩 Core Abstractions

BaseLLMClient

All providers implement the same interface:

class BaseLLMClient:
    async def generate_text(...)
    async def generate_json(...)

LLMFile

A provider-agnostic representation of file inputs:

from llm_kit.core import LLMFile

---

🔌 Providers

Each provider is implemented as an adapter that conforms to BaseLLMClient.

Supported / planned:

• OpenAI
• Gemini
• Anthropic
• Local / OSS models (future)
