Cost Optimization

intermediate ~4 hours cost-management caching models

Minimize AI application costs without sacrificing quality. This path covers the complete cost optimization toolkit: model selection, token counting, prompt caching, and batch processing — comparing approaches across Anthropic and OpenAI.

The key insight: cost optimization is not about using cheaper models everywhere. It’s about matching the right model to each task, caching repeated content, batching non-urgent work, and measuring token usage to eliminate waste. A well-optimized pipeline using GPT-4o-mini + caching can cost less than a naive GPT-3.5 implementation.

Steps

  1. Model selection openai beginner

    How to choose the right OpenAI model by balancing accuracy, latency, and cost — the fundamental tradeoff triangle for every AI application.

    Model selection is the single biggest cost lever — choosing GPT-4o-mini over GPT-4o can reduce costs 10-30x with acceptable quality for many tasks. Start here to understand the accuracy/cost/latency tradeoff triangle.

  2. Choosing A Model anthropic-platform beginner

    Anthropic's model lineup (Haiku/Sonnet/Opus) offers a similar cost spectrum. Compare pricing and capabilities with OpenAI's lineup — for many workloads, the right model at the right provider can halve your costs.

  3. Counting tokens openai beginner

    Count input tokens precisely for text, images, files, and tools using the Responses API — essential for cost management and context window planning.

    You can't optimize what you can't measure. Token counting is essential for understanding where your costs come from — often tool schemas, system prompts, and context consume more tokens than the actual user message.

  4. Token Counting anthropic-platform intermediate

    Anthropic's token counting works differently from OpenAI's (different tokenizers, different counting for images). Understanding both is essential if you use multiple providers or need to compare costs accurately.

  5. Prompt caching openai intermediate

    Learn how prompt caching reduces latency and cost for long prompts in OpenAI's API.

    Prompt caching can dramatically reduce costs for applications with repeated prefixes — system prompts, few-shot examples, and tool schemas. OpenAI caches automatically for identical prefixes, reducing input token costs.

  6. Prompt Caching anthropic-platform intermediate

    Cache system prompts and repeated context to reduce latency and costs by up to 90%.

    Anthropic's prompt caching requires explicit cache control headers but offers up to 90% cost reduction on cached content. The explicit approach gives you more control than OpenAI's automatic caching. Compare the tradeoffs in implementation complexity vs savings.

  7. Cost optimization openai advanced

    Lower your OpenAI model costs by trying our tools and strategies.

    OpenAI's comprehensive cost optimization guide covers the full toolkit: model selection, caching, batching, structured outputs to reduce token waste, and monitoring. This ties together all the individual techniques into a coherent strategy.

  8. Batch API openai intermediate

    Learn how to use OpenAI's Batch API for processing jobs with asynchronous requests, increased rate limits, and cost efficiency.

    The Batch API provides a 50% cost discount for workloads that can tolerate up to 24-hour latency. Ideal for evaluation runs, content generation, data processing, and any non-real-time pipeline.

  9. Batch Processing anthropic-platform intermediate

    Anthropic's Message Batches API offers similar cost savings. For multi-provider architectures, routing non-urgent workloads to whichever provider's batch API offers the best price/capability ratio is a powerful optimization strategy.
