OpenRouter
Unified API platform providing access to hundreds of AI models from various providers through a single interface.
OpenRouter is an AI Gateway providing access to 100+ LLMs through a unified API – ideal for model routing and cost optimization.
Explanation
OpenRouter aggregates LLMs from OpenAI, Anthropic, Google, Meta, Mistral, and open-source providers. Developers use one API to switch between models – optimizing for cost, latency, or performance. Automatic fallback on failures. Transparent per-token pricing.
Marketing Relevance
Simplifies multi-LLM strategies. Reduces vendor lock-in. Enables A/B testing different models without code changes.
Example
Marketing team routes simple queries to affordable Llama 3, complex analyses to Claude 3.5 – all through one API.
Common Pitfalls
Additional latency from routing layer. Price comparisons complex. Dependency on third-party availability.
Origin & History
OpenRouter launched in 2023 as the market fragmented: OpenAI, Anthropic, Google, open-source models. The platform solves the "which model?" problem with automatic routing.
