A pay-as-you-go gateway between AI agents and the computers that do their thinking. It makes three promises most AI services do not: it forgets what you told it, it cannot overspend your budget, and it hands you a receipt you can check yourself.
Your words are sealed on arrival, opened once to get the answer, then gone. Sable keeps a single line per job: what kind of work, how much, what it cost. Never the words. Its own dashboard cannot show you a prompt, because there is nowhere one could have been stored. One honest limit: on the standard tier the model provider on the other side still sees the words for that one call. Only the confidential tier hides them from the provider too.
Every access key can be given a hard budget, and the prepaid balance is a ceiling for all of them. Sable reserves the worst-case cost before the work runs, so a runaway agent stops at the limit instead of at your credit card. An agent can hand a helper a smaller allowance, never a bigger one, and switching off the parent switches off every helper.
Every answer comes back with a signed receipt: which model, how much, when, at what cost. Anyone can check the signature without asking Sable, the way you can check a stamped ticket without calling the ticket office. On the most private tier the receipt also proves the work ran inside a locked room in the chip.
Who it is for. Anyone running an AI agent that touches private material or works unattended: client files, medical notes, financial positions, source code, a receptionist that answers the phone at night. The agent's owner changes one line of settings to point it at Sable. Nothing else about the agent has to change.
What it costs. Pay as you go, priced in dollars and paid from a prepaid balance in USDT. A free tier that actually works. Plans at $79, $199 and $399 a month buy higher limits and extras, never cheaper compute. The baseline privacy is the same on every tier, including free; the $199 plan unlocks the locked-chip confidential mode. An agent can also pay its own bill mid-conversation, with no card and no human, which is how software will buy things from other software.
The token.§06 SABL is a community token launched in August 2026. Until this month it did nothing on the platform, and the whitepaper said so. On 2 September that changed on one point: you can optionally pay for compute and subscriptions in SABL, and paying that way burns the token and earns a discount. That part is still rolling out. It carries no yield, no vote, no share of revenue and no claim on the company. Sable's own words: a consumptive payment utility, not an investment.
What it is not, yet.§10 · §12 Sable is a very small team, one gateway and one machine. No outside computers serve its traffic. The most private mode runs two smaller open models on a CPU chip, not on the big GPU chips most of its competitors use. The whitepaper lists all of this in a section titled "What is built, and what is not," in the document meant to sell you. That table is the reason many people trust the rest of it.
A simulation of the three promises, running entirely in your browser. Nothing you type is sent anywhere, not even to Sable. The fingerprint is a real SHA-256 of your words. The receipt is really signed and really verified, with a throwaway key made when this page loaded. Sable's real receipts use a different curve and a published address; the shape is the same.
Loop: the agent resends its whole growing conversation every time, the way real agents do. Watch the hold grow until the cap refuses it. A five-cent key is Sable's own pattern: one short-lived, tightly scoped key per task. Priced at Sable's list price for sable-fast on 4 Sep 2026: $2 in, $10 out per million tokens.
The simulation above uses a throwaway key. This section uses Sable's real, published one. Status and signer are read live from Sable's public API. The receipt check runs in your browser and sends nothing to Sable or to this site.

Eight projects that sell private or provable AI compute, read against their own documentation. Not a scorecard. Sable is smaller than every project here and wins on a narrower set of columns than its fans assume.

Sable's confidential tier serves two small open models on CPU-only TDX; its standard tier is not confidential, in its own words. Phala, NEAR AI, Nillion, Secret and Tinfoil run models on GPU confidential computing. That is the clearest capability gap. Signed responses are no longer unique to Sable: Phala, NEAR AI and Nillion ship them. What remains unmatched is the combination of hard per-key caps, shrink-only sub-keys, live x402 and metered sandboxes behind one key.
Market cap, log scale. SABL's only role is an optional pay-in that burns the token for a discount, announced 2 Sep and not yet live. No yield, no governance, no claim. Every other bar is a gas, staking or payment token. Read the distance, not the ranking.
SABL: DexScreener, PumpSwap SABL/SOL pair created 25 Aug 2026, 24h volume $107K, 24h change -20%, read 4 Sep 2026 16:00 UTC. Others: CoinGecko circulating market cap, 4 Sep 2026. Tinfoil has no token. Super Protocol's token is not trading. SABL pay-in: whitepaper section 06 as re-rendered on 2 Sep 2026, still labelled v2.0 August; the pricing page and billing docs list USDT only.
What SABL's cap would look like if the market priced it in a peer's band, and what would have to happen first. The only mechanical link between usage and the token is the burn on pay-in, and that rail is not live yet.
Secret Network is the cautionary bar on this card: a first-generation privacy chain whose operating company ended development on 1 September 2026, with a 75 percent supply mint to fund continuity. Team continuity is the risk that no feature column captures.
Sable's whitepaper says where its previous version was incorrect. A page that grades Sable on honesty should do the same. Every correction stays here.
