Submit or Correct an AI Tool, Model, or Provider

Capital & Compute maintains a set of directories covering the AI infrastructure stack: who serves inference, what the models cost per token, which benchmarks mean anything, and which agent extensions are worth installing. Every entry is grounded to a primary source and carries the date it was last checked.

There are two ways to contribute to that: submit something that is missing, or correct something that has gone stale. Both go to contact@capitalandcompute.net.

What gets tracked

Each directory records a fixed set of fields. Knowing which ones apply to you is the difference between a submission that can be verified in one pass and one that cannot be used at all.

• Inference providers (35 listed): category, region, what the platform serves, pricing model (per token, per GPU hour, consumption, or mixed), a representative price example, OpenAI API compatibility, free tier terms, and separate home, pricing, and documentation URLs.
• Models: per-token input and output rates, cached input pricing where offered, context length, release and deprecation dates, and the official pricing page each rate is read from.
• Benchmarks (117 listed): what it measures, who built it and in what year, task format and size, the scoring metric, whether it is live or saturated or retired, a representative top score, and the official leaderboard.
• Free model APIs: which host serves it, context length, whether the weights are open, and the terms that actually matter for a free tier: signup requirements, phone verification, rate limits, and whether inputs are used for training.
• Skills, MCP servers, and prompt libraries (156 listed): type, category, maintainer, how it is installed, and the tags that make it findable.

How submissions are evaluated

Every submission is checked against the same questions before anything is written down:

• Is the product actually available to the public, rather than announced or waitlisted?
• Is the pricing verifiable on an official page, not only in a blog post or a press release?
• Is there official documentation a reader can go and check?
• Can every claim be confirmed independently of the vendor making it?
• Is it within scope: the AI infrastructure and cost stack, not adjacent SaaS?
• Are benchmark numbers attributed to whoever ran them, and reported with the harness and subset they came from?
• Is it meaningfully distinct from entries already listed?

An accepted entry enters as representative: grounded to its official URL and stamped with the date it was read. It is promoted to verified only once its numbers are re-checked against that same page. Both states are visible on the page, so a reader always knows which one they are looking at. Prices and specs move weekly in this sector, and pretending otherwise is how a directory quietly becomes wrong.

What to send

Keep it short and link everything. A useful submission gives the official product URL, the official pricing page, the documentation, and a primary source for every number quoted. Marketing copy and press kits are not usable: if a figure cannot be traced to a page the vendor publishes and maintains, it does not get recorded. That rule is the whole reason these directories are worth citing, and it is set out in full in our editorial standards.

Report an outdated price or wrong spec

Corrections are as valuable as new entries, and often more so. If a price has changed, a model has been deprecated, a free tier has been withdrawn, or a specification is simply wrong, send four things: the page it appears on, the field that is wrong, the correct value, and the official source that shows it. Corrections are made promptly and the entry is re-dated, per our corrections policy.

This applies to your own product as much as to anyone else's. If we have you listed at a price you no longer charge, tell us.

Paid listing options

Two paid options sit on top of a listing:enhanced listing (a logo, extended description, and direct link on your entry) and featured listing (a labelled sponsored slot at the top of a directory). Every paid entry is checked against the criteria above like any other, and none of them changes a ranked position. Details and quotes are on the advertising and listings page.

A listing is not a guaranteed page

A verified submission earns a row in the relevant directory. Some entries also get a dedicated page of their own, but only where there is genuinely enough to say: how the thing works, how its pricing behaves in practice, where it falls short, and who it suits. A directory row restated as a short page is thin content, and thin content helps nobody. So the entry comes first and the page follows if and when it is earned.

Guest posts and link placements

Neither is accepted, and it is worth being direct about why. Capital & Compute publishes under its brand rather than individual bylines, so there is no byline to offer a contributor. And selling links that pass ranking signals violates Google's spam policies, which is a bad trade for a publication whose only real asset is that its rankings are not for sale.

If you were planning to pitch a guest post, the useful alternatives are a directory listing, standard or paid, or a sponsored placement under a clear label. Pitches for link insertions, link exchanges, and sponsored do-follow links are declined without reply.

Where to send it

Email contact@capitalandcompute.net. Put "submission" or "correction" in the subject line so it routes correctly. Genuine submissions get a reply within a few business days, and being listed is not conditional on hearing back first: entries are added as they are verified.
