You can reduce LLM API costs by implementing model routing, which automatically sends simple tasks to cheaper models and complex tasks to higher-quality models, balancing overall expenditure and performance.

Prompt caching lowers LLM spending by storing and reusing previously sent long prompts, avoiding the need to re-process identical context tokens and significantly reducing API latency and token usage fees.

Yes, you can enforce strict budget tracking across multiple LLM providers using immutable cost tracking, which records every API call permanently without mutating state to ensure accurate financial auditing.

The best way to handle LLM API failures within budget is using narrow retry logic, which retries only transient errors and fails fast on authentication or validation issues to prevent runaway costs.

Yes, model routing works for mixed-complexity tasks by evaluating each prompt's difficulty and dynamically assigning it to the most cost-effective model available across your configured LLM providers.

You should avoid automated cost optimization for LLM pipelines when processing tasks require a single specific high-capability model, as dynamic routing may inadvertently assign complex prompts to less capable models.
