@f3d1/llmkit-shared

Shared types, constants, and pricing data for LLMKit packages.

What's in it

• TypeScript types: LLMRequest, LLMResponse, CostBreakdown, TokenUsage, ProviderName, Budget, and more
• Pricing table: per-token costs for 11 providers (OpenAI, Anthropic, Gemini, Groq, Together, Fireworks, DeepSeek, Mistral, xAI, Ollama, OpenRouter) and 700+ models, including cache read/write rates where applicable
• Cost calculation: calculateCost(), calculateCostBreakdown(), getModelPricing()
• Provider inference: inferProvider() resolves a model name to its provider
• Error types: shared error definitions across LLMKit packages

Install

npm install @f3d1/llmkit-shared

Usage

import { calculateCost, inferProvider, getModelPricing } from '@f3d1/llmkit-shared';

const cost = calculateCost('anthropic', 'claude-sonnet-4-6', 1000, 500);
// -> 0.0105 (USD)

const provider = inferProvider('gpt-4.1');
// -> 'openai'

const pricing = getModelPricing('openai', 'gpt-4.1');
// -> { inputPerMillion: 2.0, outputPerMillion: 8.0 }
