Is OpenRouter worth the price?
OpenRouter's 'Pay as you go' model is inherently fair and generous, as users only pay for what they consume, with no upfront costs or commitments.
Pricing varies significantly by model, which is standard for LLM APIs, allowing users to choose cost-effective options. This model is best for developers and businesses needing flexible access to a wide range of LLMs without vendor lock-in.
Hidden Costs & Gotchas
Model-specific token costs can vary widely.
Potential for unexpected high usage bills.
No bulk discounts advertised for high volume.
How OpenRouter Compares to Competitors
Compared to direct LLM providers like OpenAI, OpenRouter offers a unified API, potentially simplifying integration. While specific token prices might be slightly higher for some models than going direct, the convenience and automatic routing add significant value. Anthropic's Claude 3 Opus, for instance, is $15/M input and $75/M output tokens, which OpenRouter also reflects, but they offer access to many other models for comparison.
