Provides a unified JavaScript/TypeScript API that abstracts over multiple LLM providers (OpenAI, Anthropic, Google Gemini) by normalizing their different request/response schemas into a common interface. Internally maps provider-specific parameters (temperature, max_tokens, stop sequences) to each provider's native format, eliminating the need for developers to write conditional logic for each provider.
Unique: Normalizes request/response schemas across OpenAI, Anthropic, and Google Gemini APIs into a single interface, with runtime provider selection rather than compile-time configuration
vs alternatives: Lighter-weight than LangChain's provider abstraction with faster initialization, but less comprehensive feature coverage for advanced use cases
Automatically captures and sends LLM interaction events (prompts, completions, token usage, latency, errors) to PostHog analytics backend for observability and debugging. Hooks into the LLM call lifecycle to extract structured event data without requiring manual instrumentation, enabling teams to track AI feature adoption, cost, and performance in production.
Unique: Automatic lifecycle hooks into LLM calls that extract and batch events to PostHog without explicit instrumentation, with built-in cost tracking and provider-specific metrics
vs alternatives: More integrated with PostHog's event model than generic logging solutions, but requires PostHog infrastructure vs language-agnostic alternatives like OpenTelemetry
Provides a templating system for prompts with variable interpolation, type validation, and automatic escaping to prevent prompt injection. Supports Handlebars-style syntax for conditionals and loops, validates that all required variables are provided before sending to LLM, and logs template variables for debugging.
Unique: Integrated prompt templating with automatic variable escaping and type validation, preventing prompt injection while supporting complex template logic
vs alternatives: More security-focused than simple string interpolation, but less feature-rich than dedicated prompt management platforms
Enables LLM responses to be constrained to a JSON schema (via provider-native features like OpenAI's JSON mode or Anthropic's tool_use) and automatically parses/validates the output against the schema. Handles provider differences in schema enforcement (some providers support JSON Schema directly, others use tool definitions) and provides fallback parsing for providers without native support.
Unique: Abstracts provider-specific schema enforcement mechanisms (OpenAI JSON mode vs Anthropic tool_use) into a unified API with automatic fallback validation for providers without native support
vs alternatives: Simpler than Zod/Pydantic for LLM-specific validation, but less flexible for complex type transformations
Provides a declarative schema-based registry for defining tools/functions that LLMs can invoke, automatically converting tool definitions to each provider's native format (OpenAI function calling, Anthropic tool_use, Google function calling). Handles tool execution, result formatting, and multi-turn agentic loops where the LLM can iteratively call tools and refine responses.
Unique: Unified schema-based tool registry that automatically transpiles to each provider's native function calling format, with built-in support for multi-turn agentic loops and tool result formatting
vs alternatives: More lightweight than LangChain's tool abstraction with faster initialization, but lacks built-in error handling and retry logic
Manages conversation history and automatically handles context window constraints by implementing sliding window or summarization strategies. Tracks token counts per message, calculates remaining context budget, and can automatically trim or summarize older messages to fit within provider token limits while preserving conversation coherence.
Unique: Automatic context window management with provider-aware token counting and configurable trimming strategies (sliding window vs summarization) built into the message history abstraction
vs alternatives: More integrated than manual token counting, but less sophisticated than LangChain's memory abstractions for complex retrieval-augmented scenarios
Provides an event-based streaming API that normalizes streaming responses across different LLM providers, emitting events for token chunks, completion status, and errors. Internally handles provider-specific streaming protocols (Server-Sent Events for OpenAI, different formats for Anthropic) and buffers partial tokens to emit complete words/sentences rather than individual tokens.
Unique: Normalizes streaming protocols across OpenAI (SSE), Anthropic, and Google into a unified event-based API with automatic token buffering for word-level granularity
vs alternatives: Simpler than raw provider streaming APIs, but less feature-rich than full-featured streaming libraries with built-in retry and reconnection logic
Automatically calculates and tracks LLM API costs by multiplying token counts (input/output) by provider-specific pricing rates. Maintains cost aggregations by model, provider, and time period, and integrates with PostHog analytics for cost dashboards. Supports custom pricing configurations for fine-tuned models or enterprise pricing agreements.
Unique: Automatic cost calculation integrated into LLM call lifecycle with provider-aware pricing rates and PostHog event emission for cost dashboards
vs alternatives: More integrated than manual cost tracking, but less comprehensive than dedicated LLM cost management platforms like Helicone or LangSmith
