Provides a unified API for counting tokens across 6+ LLM providers (OpenAI, Anthropic, Gemini, Mistral, Groq, DeepSeek) by wrapping each provider's native tokenization logic or implementing compatible algorithms. Uses provider-specific token encoders (e.g., tiktoken for OpenAI, claude-tokenizer for Anthropic) behind a normalized interface, allowing developers to swap providers without changing token-counting code. Handles model-specific tokenization differences (e.g., different BPE vocabularies, special token handling) transparently.
Unique: Zero-dependency design that bundles provider-specific tokenizers locally rather than making API calls or requiring external services, enabling offline token counting with no network latency or rate limits
vs alternatives: Faster and more cost-effective than calling each provider's API for token counts, and more accurate than generic BPE approximations because it uses provider-native encoders
Automatically calculates monetary cost for each LLM API request by multiplying token counts (input + output) by provider-specific pricing rates. Maintains an internal pricing table for each provider and model, updated to reflect current pricing. Supports both streaming and non-streaming requests, calculating costs incrementally as tokens arrive. Returns cost breakdowns (prompt cost, completion cost, total) alongside token counts, enabling per-request cost visibility without manual billing API queries.
Unique: Calculates costs at request granularity (not just at billing cycle end) by embedding pricing logic directly in the request path, enabling real-time cost visibility and per-request decision-making without external billing API calls
vs alternatives: Provides immediate cost feedback per request (vs. waiting for monthly bills), and integrates cost calculation into application logic (vs. external billing dashboards that lack real-time granularity)
Tracks token usage and cost for streaming LLM responses by intercepting and counting tokens as they arrive in chunks, rather than waiting for the complete response. Maintains running totals of prompt tokens, completion tokens, and cost as the stream progresses. Works by wrapping streaming response handlers or middleware to parse token counts from provider-specific stream metadata (e.g., OpenAI's usage field in stream deltas). Enables cost visibility before streaming completes, supporting early termination or cost-aware stream handling.
Unique: Intercepts streaming responses at the middleware level to extract and aggregate token counts from provider-specific stream deltas, enabling cost visibility before stream completion without buffering the entire response
vs alternatives: Provides real-time cost feedback during streaming (vs. batch cost calculation after completion), and supports cost-aware stream termination (vs. passive cost tracking)
Integrates with LLM client libraries (OpenAI SDK, Anthropic SDK, etc.) via middleware or wrapper patterns to automatically inject cost tracking into every API call without modifying application code. Intercepts requests before they're sent and responses after they're received, extracting token counts and calculating costs transparently. Supports both callback-based and promise-based middleware patterns, and works with async/await code. Accumulates costs across multiple requests, enabling application-level cost aggregation and reporting.
Unique: Implements transparent middleware integration that hooks into provider SDKs at the request/response level, enabling automatic cost tracking without modifying application code or requiring explicit cost calculation calls
vs alternatives: Reduces boilerplate compared to manual cost tracking in every LLM call, and provides automatic aggregation vs. requiring developers to manually sum costs
Aggregates costs across multiple requests and provides structured reports broken down by time period, model, provider, or custom categories. Maintains running totals and supports queries like 'total cost in last hour', 'cost by model', 'cost by provider'. Implements in-memory cost accumulation with optional export to JSON or CSV for external analysis. Supports custom tagging of requests (e.g., by user, feature, or endpoint) to enable cost attribution and chargeback scenarios.
Unique: Provides in-memory cost aggregation with flexible grouping (by model, provider, time, or custom tags) and export capabilities, enabling cost attribution and analysis without requiring external analytics infrastructure
vs alternatives: Simpler than integrating external analytics platforms, and supports custom tagging for cost attribution (vs. provider dashboards that only show aggregate costs)
Manages a versioned pricing table for all supported models across all providers, allowing developers to update rates as providers change pricing. Supports both built-in default pricing (updated with library releases) and custom pricing overrides for specific models or providers. Implements a configuration API to set custom rates programmatically, and supports loading pricing from external sources (JSON files, environment variables, or APIs). Tracks pricing version to enable cost recalculation with historical rates if needed.
Unique: Provides a configuration API for custom pricing overrides with version tracking, enabling organizations to use negotiated rates and maintain audit trails without modifying library code
vs alternatives: More flexible than hardcoded pricing (supports custom rates), and simpler than building a separate pricing service (built-in configuration management)
Implements budget tracking and enforcement by monitoring cumulative costs against user-defined spending limits. Supports per-request budget checks (reject requests that would exceed budget), per-session limits, and per-time-period limits (e.g., daily, monthly). Provides callback hooks or event emitters to trigger alerts when costs approach or exceed thresholds. Integrates with cost tracking to enable real-time budget enforcement without external services.
Unique: Implements in-process budget enforcement with real-time alerts, enabling cost control without external services or API calls, and supporting request-level budget checks for immediate cost prevention
vs alternatives: Faster and more responsive than external budget services (no API latency), and enables request-level enforcement (vs. post-hoc billing alerts)
Analyzes historical cost and token usage data to recommend the most cost-efficient models for specific use cases. Calculates efficiency metrics (cost per token, cost per request, tokens per dollar) for each model and provides rankings. Supports filtering by quality constraints (e.g., 'recommend models with >90% quality score') or latency constraints. Enables A/B testing by comparing costs across models for the same prompts or use cases.
Unique: Analyzes historical cost data to generate model recommendations with efficiency rankings, enabling data-driven model selection without external analytics platforms
vs alternatives: Provides automated recommendations based on actual usage patterns (vs. manual comparison), and integrates with cost tracking for seamless analysis
Automatically loads and parses documents from diverse sources (PDFs, Word docs, HTML, Markdown, code files, databases) into a unified in-memory representation using format-specific loaders and node-based document abstractions. Each document is decomposed into Document objects containing metadata, content, and relationships, enabling downstream processing without format-specific handling in application code.
Unique: Provides a unified loader abstraction (BaseReader interface) that normalizes 100+ data source connectors into a single Document/Node API, eliminating format-specific branching logic in application code. Loaders are composable and chainable, allowing sequential transformations (e.g., load → split → extract metadata → embed).
vs alternatives: Broader out-of-the-box loader coverage than LangChain's document loaders and more structured node-based decomposition than raw text splitting, reducing boilerplate for multi-source RAG pipelines.
Splits documents into semantically coherent chunks using multiple strategies (character-based, token-aware, recursive, semantic) with configurable overlap and chunk size. Preserves document hierarchy and metadata through a node tree structure, enabling retrieval systems to maintain context relationships and enable hierarchical re-ranking or parent-document retrieval patterns.
Unique: Implements a node-tree abstraction that preserves document hierarchy and enables parent-document retrieval patterns. Supports multiple splitting strategies (recursive, semantic, code-aware) with pluggable custom splitters, and automatically propagates metadata through the node tree.
vs alternatives: More sophisticated than LangChain's text splitters because it preserves hierarchical relationships and supports semantic splitting; better for complex document structures than simple character-based splitting.
LlamaIndex scores higher at 40/100 vs ai-cost-meter at 39/100. However, ai-cost-meter offers a free tier which may be better for getting started.
