Frequently asked questions

Anthropic FAQs

How much does the Anthropic Claude API cost?

Claude 4 Opus costs $15/1M input and $75/1M output tokens. Claude Sonnet 4.5 is $3/$15 per 1M tokens. Claude Haiku 3.5 is the budget option at $0.80/$4.00. Prompt caching reduces input costs by up to 90%.

What is the context window for Claude models?

All Claude models support a 200,000-token context window, making them ideal for processing long documents, codebases, or multi-turn conversations without truncation.

How does Anthropic prompt caching work?

Anthropic's prompt caching lets you mark portions of your prompt (system prompts, documents, tool definitions) to be cached server-side. Cached tokens are billed at 10% of the standard input price after the first write, making repeated long-context calls dramatically cheaper.

Lepton AI FAQs

What models does Lepton AI support?

Lepton AI hosts Llama 3.3 70B and other popular open-weight models. Their catalog is focused on the most widely-used models rather than breadth.

How does Lepton AI pricing compare to competitors?

Lepton AI offers competitive pricing on Llama 3.3 70B, comparable to Together AI and Fireworks AI. Check their pricing page for current rates.

Is Lepton AI good for production workloads?

Lepton AI is suitable for production workloads with auto-scaling and serverless infrastructure. For very high-volume or latency-critical production use cases, Groq or Cerebras may offer better performance.

Provider category context

Anthropic is a frontier lab, founded in 2021. Lepton AI is a inference api, founded in 2023. Anthropic as a frontier lab trains and serves its own proprietary models. Lepton AI as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers but without access to proprietary frontier models.

How to choose between them

Choose Anthropic if you need top coding benchmark scores (claude 4 opus). Choose Lepton AI if you need clean developer experience with minimal setup. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
