LLMPrice

A Python Library for LLM Pricing Lookup

Fast, offline-first LLM pricing lookup for 2500+ models across all major providers. Returns both Python objects and JSON.

Data synced daily from LiteLLM via GitHub Actions. Published weekly to PyPI with date-based versioning.

Also available as a TypeScript/npm package.

Install

pip install llmprice-kit

Quick Start

from llmprice import LLMPrice

lp = LLMPrice()

# Get pricing as Python object
model = lp.get("gpt-4o")
print(model.input_cost_per_1m)   # 2.5
print(model.output_cost_per_1m)  # 10.0
print(model.max_input_tokens)    # 128000
print(model.supports_vision)     # True

# Get as JSON dict
data = lp.get_json("gpt-4o")
# {"name": "gpt-4o", "provider": "openai", "input_cost_per_1m": 2.5, ...}

# Compare models
models = lp.compare(["gpt-4o", "claude-opus-4-20250514", "gemini/gemini-2.0-flash"])
for m in models:
    print(f"{m.name}: ${m.input_cost_per_1m}/1M in, ${m.output_cost_per_1m}/1M out")

# Search by capabilities
cheap_vision = lp.search(supports_vision=True, max_input_price=1.0)
reasoning = lp.search(supports_reasoning=True, provider="anthropic")

# List providers
lp.providers()  # ['anthropic', 'openai', 'gemini', ...]

# Auto-update mode (fetches fresh data if >1 day old)
lp = LLMPrice(auto_update=True)

CLI

llmprice get gpt-4o
llmprice compare gpt-4o claude-opus-4-20250514
llmprice search --provider openai --vision
llmprice search --reasoning --max-input-price 5.0
llmprice providers
llmprice update

How It Works

• Bundled data — Ships with a pricing snapshot, works offline with zero latency
• Auto-sync — GitHub repo updated daily from LiteLLM upstream
• Weekly PyPI releases — Published every Monday with date-based version
• Auto-update mode — LLMPrice(auto_update=True) fetches fresh data when local copy is >1 day old
• Dual output — Every query returns Python dataclass objects or JSON dicts

Examples
