AIModels

A collection of AI model specifications across different providers. This package provides normalized data about AI models, including their capabilities, context windows, and pricing information.

Installation

pip install aimodels.dev

Usage

from aimodels import models

# Find models by capability
chat_models = models.can("chat")
vision_models = models.can("img-in")
reasoning_models = models.can("reason")

# Fluent API (equivalent to the capability filters above)
fluent_chat = models.canChat()
fluent_multimodal = models.canChat().canSee()

# Find models with multiple capabilities
multimodal_models = models.can("chat", "img-in")
audio_models = models.can("audio-in", "audio-out")
full_stack_models = models.can("chat", "fn-out", "json-out")

# Find models by provider
openai_models = models.from_provider("openai")

# Find models by creator
meta_models = models.from_creator("meta")

# Find models by context window
large_context_models = models.with_min_context(32768)

# Find specific model
model = models.id("gpt-4")
print(model.context.total)  # Context window size
print(model.providers)  # ['openai']

# Get pricing information (via provider pricing table)
provider = models.get_provider("openai")
if provider and provider.pricing:
    pricing = provider.pricing.get("gpt-4")
    if isinstance(pricing, dict) and pricing.get("type") == "token":
        print(f"Input: ${pricing['input']}/1M tokens")
        print(f"Output: ${pricing['output']}/1M tokens")

# Get provider information
if provider:
    print(f"Name: {provider.name}")
    print(f"Website: {provider.websiteUrl}")
    print(f"API: {provider.apiUrl}")

Features

• Comprehensive database of AI models from major providers (OpenAI, Anthropic, Mistral, etc.)
• Normalized data structure for easy comparison
• Model capabilities (chat, img-in, img-out, function-out, etc.)
• Context window information
• Creator and provider associations
• Type hints with full type safety
• Zero dependencies
• Regular updates with new models
