Kaeva Labs — UNBLOCK

A marketplace where AI agents buy
the knowledge they need to ship.

When an AI agent gets stuck, it purchases a validated block of workflow knowledge, settles the payment in under five seconds, and continues. Creators earn on every purchase.

Founding Creator Program — open now

First 100 creators to mint on the public devnet earn 75% lifetime royalty on every block they mint. Kaeva waives its protocol fee on your blocks, forever. Migrates 1:1 to mainnet.

Benchmark — 6 arms, 200 completions

A $0.50 block beats every frontier model operating blind.

90.5% vs ~~81.5%~~

Gemma 3 12B + one UNBLOCK block vs Claude Sonnet 4.6 alone. Same 50 tasks, same judge.

Model	Block	Think	Accuracy	$/task
Gemma 3 12B	—	—	43.0%	$0.00
Gemma 3 12B	$0.50	—	90.5%	$0.50
Sonnet 4.6	—	default	81.5%	$0.24
Sonnet 4.6	$0.50	default	94.0%	$0.74
Opus 4.6	—	32K max	81.5%	$0.05
Opus 4.6	$0.50	32K max	89.5%	$0.55

Opus 4.6 with max extended thinking = 81.5%. Same as Sonnet baseline. Max reasoning budget can't overcome frozen weights. A $0.50 block can.

50 technical debugging tasks. 4 original arms + 2 Opus-max-thinking arms. 200 completions. LLM-as-judge grading. Total benchmark spend: $4.18. The gap between cutoff and today widens with every release. Context is more valuable than weights.

Why it matters

Agents get stuck on things humans already know.

Most failed agent runs fail on specific, recoverable gaps — a config value, an API quirk, a workflow step. Frontier models froze before the hardware-stack combination stabilized.

Knowledge needs a market, not another database.

The value lives with the practitioners who solved the problem once. UNBLOCK lets them sell that solution to every agent that needs it — on-chain, with auto-split royalties.

Payments belong inside the agent loop.

Sub-second settlement at the point of failure. No human in the middle, no subscription, no friction between a stuck agent and a shipped task. HTTP 402 native.
