Installation

pip install bhumi

Quick Start

OpenAI Example

import asyncio
from bhumi.base_client import BaseLLMClient, LLMConfig
import os

api_key = os.getenv("OPENAI_API_KEY")

async def main():
    config = LLMConfig(
        api_key=api_key,
        model="openai/gpt-4o",
        debug=True
    )
    
    client = BaseLLMClient(config)
    
    response = await client.completion([
        {"role": "user", "content": "Tell me a joke"}
    ])
    print(f"Response: {response['text']}")

if __name__ == "__main__":
    asyncio.run(main())

⚡ Performance Optimizations

Bhumi includes cutting-edge performance optimizations that make it 2-3x faster than alternatives:

🧠 MAP-Elites Buffer Strategy

• Ultra-fast archive loading with Satya validation + orjson parsing (3x faster than standard JSON)
• Trained buffer configurations optimized through evolutionary algorithms
• Automatic buffer adjustment based on response patterns and historical data
• Type-safe validation with comprehensive error checking
• Secure loading without unsafe eval() operations

📊 Performance Status Check

Check if you have optimal performance with the built-in diagnostics:

from bhumi.utils import print_performance_status

# Check optimization status
print_performance_status()

• Satya-powered type validation for bulletproof data loading
• Performance metrics and diagnostics

Gemini Example

import asyncio
from bhumi.base_client import BaseLLMClient, LLMConfig
import os

api_key = os.getenv("GEMINI_API_KEY")

async def main():
    config = LLMConfig(
        api_key=api_key,
        model="gemini/gemini-2.0-flash",
        debug=True
    )
    
    client = BaseLLMClient(config)
    
    response = await client.completion([
        {"role": "user", "content": "Tell me a joke"}
    ])
    print(f"Response: {response['text']}")

if __name__ == "__main__":
    asyncio.run(main())

Provider API: Multi-Provider Model Format

Bhumi unifies providers using a simple provider/model format in LLMConfig.model. Base URLs are auto-set for known providers; you can override with base_url.

• Supported providers: openai, anthropic, gemini, groq, sambanova, openrouter
• Foundation providers use provider/model. Gateways like Groq/OpenRouter/SambaNova may use nested paths after the provider (e.g., openrouter/meta-llama/llama-3.1-8b-instruct).

from bhumi.base_client import BaseLLMClient, LLMConfig

# OpenAI
client = BaseLLMClient(LLMConfig(api_key=os.getenv("OPENAI_API_KEY"), model="openai/gpt-4o"))

# Anthropic
client = BaseLLMClient(LLMConfig(api_key=os.getenv("ANTHROPIC_API_KEY"), model="anthropic/claude-3-5-sonnet-latest"))

# Gemini (OpenAI-compatible endpoint)
client = BaseLLMClient(LLMConfig(api_key=os.getenv("GEMINI_API_KEY"), model="gemini/gemini-2.0-flash"))

# Groq (gateway) – nested path after provider is kept intact
client = BaseLLMClient(LLMConfig(api_key=os.getenv("GROQ_API_KEY"), model="groq/llama-3.1-8b-instant"))

# SambaNova (gateway)
client = BaseLLMClient(LLMConfig(api_key=os.getenv("SAMBANOVA_API_KEY"), model="sambanova/Meta-Llama-3.1-405B-Instruct"))

# OpenRouter (gateway)
client = BaseLLMClient(LLMConfig(api_key=os.getenv("OPENROUTER_API_KEY"), model="openrouter/meta-llama/llama-3.1-8b-instruct"))

# Optional: override base URL
client = BaseLLMClient(LLMConfig(api_key="...", model="openai/gpt-4o", base_url="https://api.openai.com/v1"))

Tool Use (Function Calling)

Bhumi supports OpenAI-style function calling and Gemini function declarations. Register Python callables with JSON schemas; Bhumi will add them to requests and execute tool calls automatically.

import os, asyncio, json
from bhumi.base_client import BaseLLMClient, LLMConfig

# 1) Define a tool
def get_weather(location: str, unit: str = "celsius"):
    return {"location": location, "unit": unit, "forecast": "sunny", "temp": 27}

tool_schema = {
    "type": "object",
    "properties": {
        "location": {"type": "string", "description": "City and country"},
        "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]}
    },
    "required": ["location"]
}

async def main():
    client = BaseLLMClient(LLMConfig(api_key=os.getenv("OPENAI_API_KEY"), model="openai/gpt-4o", debug=True))
    client.register_tool("get_weather", get_weather, "Get the current weather", tool_schema)

    # 2) Ask a question that should trigger a tool call
    resp = await client.completion([
        {"role": "user", "content": "What's the weather in Tokyo in celsius?"}
    ])

    print(resp["text"])  # Tool is executed and response incorporates tool output

asyncio.run(main())

Notes:

• OpenAI-compatible providers use tools with tool_calls in responses; Gemini uses function_declarations and tool_config under the hood.
• Bhumi parses tool calls, executes your Python function, appends a tool message, and continues the conversation automatically.

Structured Output via Pydantic

Generate schema-conformant JSON using a Pydantic model. Bhumi registers a hidden tool generate_structured_output for the model; the LLM will call it to return strictly-typed data.

from pydantic import BaseModel
from bhumi.base_client import BaseLLMClient, LLMConfig

class UserInfo(BaseModel):
    """Return the user's full_name and age"""
    full_name: str
    age: int

async def main():
    client = BaseLLMClient(LLMConfig(api_key=os.getenv("OPENAI_API_KEY"), model="openai/gpt-4o", debug=True))
    client.set_structured_output(UserInfo)

    resp = await client.completion([
        {"role": "user", "content": "Extract name and age from: Alice Johnson, age 29"}
    ])

    # The model uses the registered tool so the final message contains strict JSON
    print(resp["text"])  # e.g., {"full_name": "Alice Johnson", "age": 29}

asyncio.run(main())

Dependencies: structured output uses Pydantic v2. Ensure pydantic>=2 is installed (bundled as a dependency).

Streaming Support

All providers support streaming responses:

async for chunk in await client.completion([
    {"role": "user", "content": "Write a story"}
], stream=True):
    print(chunk, end="", flush=True)
