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
Grok 4.6
SpaceXAI's frontier text-and-image model for coding, agentic tasks, and knowledge work, with direct web, X, and code tools.
Best for
- Coding agents with live web or X context
- Tool-heavy knowledge workflows
- Teams already building on OpenAI-compatible APIs
Watch out for
Published regions are narrower than a generic 'global' label, and the base token rate doubles for long-context requests.
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.

| InputsMedia types accepted by the listed model endpoint. | Text, image | Text, image, video, PDF |
| Tools & agentsSelected native tools and agent-building capabilities, not an exhaustive list. | Functions, web/X search, code execution | Parallel tools, coding, long-running agents, high reasoning |
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.
Grok 4.6
SpaceXAI says API inputs and outputs are never used for training without explicit permission. Requests are encrypted and retained for 30 days by default; team-level zero data retention is available with feature tradeoffs.

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.
