Estimate your cost

Set your usage. Your estimate updates as you type.

Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.

One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

How this estimate works

Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take

Muse Spark 1.3

Meta's latest multimodal reasoning model for long-running agents, coding, tools, and complex user collaboration.

Best for

  • Long-horizon coding and agent projects
  • Tool workflows that need user checkpoints
  • Multimodal work over files, images, video, and PDFs

Watch out for

Meta's public launch does not publish every operational limit or one complete API data-use commitment. Check the live model page, price, region, retention controls, and maximum output before production.

DeepSeek-V4-Flash

DeepSeek's lower-cost V4 model for high-volume reasoning, coding, agents, and million-token text workloads.

Best for

  • Cost-efficient coding and agent workloads
  • Large-context text analysis
  • High-concurrency applications using familiar API formats

Watch out for

Flash's knowledge cutoff and universal latency are not published. Do not confuse it with Flash-Vision-Exp, and verify peak pricing, cache behavior, output budgets, jurisdiction, and data handling.

How to choose

Compare the job, not the hype.

Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.

Muse Spark 1.3

The public Muse Spark model and release pages reviewed do not state one complete API retention or training-use commitment. Check the current Meta Model API terms and account controls before using private data.

DeepSeek-V4-Flash

DeepSeek documents its Responses API as stateless and says responses and conversations are not stored by that endpoint. This is not a complete account-wide retention or training-use promise; review current platform terms and automatic cache behavior for sensitive data.
