NEURON

1 NEURON = $1 of inference

NEURON … · 1 NEURON = $1 of inference

Priced on the NEURON/KAI pool on Base through KAI/USDC; the par door at $1.00 is always open. The pools' own fees come on top, and the Buy card quotes the exact fill.

* Past 200K to 272K tokens of context, by model, these models bill a higher tier, up to 4 times the base input price. The gateway reserves at the dearest tier before a request runs, then charges exactly what Venice reports the request cost, at list, with no markup.

Images 41

A picture from a text prompt, priced per image; some models price by resolution and quality.

A tiered model is priced by the resolution and the quality /image/generate names, and two prices on one resolution are its low and its high quality. OpenAI's images/generations bills its default.

Buy

Two doors, both on Base. The market sells under a dollar while its asks last; the par door is $1.00, always.

Buy on the market

Reading the pool…

The NEURON/KAI pool on Base; a USDC buy passes KAI's own USDC pool on the way, whose fees feed KAI and its backers. The fee row is read off both pools; your slippage is the only bound on the fill.

Mint at $1

One USDC in, one NEURON out, always. The dollar stays behind the NEURON until it is used for inference.

USDC

Balance 0 USDC

NeuronMinter on Base. The same contract stands at the same address on Robinhood Chain and Arc and mints there against their own dollars; this page mints on Base.

Use

Activate on Base, sign for a key, call any model above.

Activate

Activation burns the NEURON on Base and credits its dollars to your address at the gateway: 1 NEURON becomes $1 of inference at list price. It is final; an activated dollar is spent on inference and on nothing else.

NEURON

On Base -Activated -

Holding NEURON on Robinhood Chain or Arc? Activate there through NeuronBridge's activateOnBase: the NEURON burns on that chain and the credit lands on Base, the same one balance.

Get a key

One signature from the wallet that activated, no gas. The key spends that address's activated dollars; a limit fences it inside them, for a bot or a teammate.

const ai = new OpenAI({baseURL: 'https://api.kairence.ai/api/v1', apiKey: process.env.KAIRENCE_KEY});
console.log((await ai.chat.completions.create({model: 'zai-org-glm-5', max_tokens: 500, messages: [{role: 'user', content: 'Hello'}]})).choices[0].message.content);
const imageBase64 = (await ai.images.generate({model: 'venice-sd35', prompt: 'A lighthouse at dawn', size: '1024x1024'})).data[0].b64_json;
const mp3 = Buffer.from(await (await ai.audio.speech.create({model: 'tts-kokoro', input: 'Hello from NEURON', voice: 'af_alloy'})).arrayBuffer());
const vector = (await ai.embeddings.create({model: 'text-embedding-bge-m3', input: 'Hello'})).data[0].embedding;

Name max_tokens: a request without it reserves the model's whole maximum output before it runs, and a small balance will not cover that.

Images: /image/generate bills the resolution and quality it names, one image a request. The SDK's images.generate is OpenAI's images/generations, which bills the model's default.

Backed

A dollar of USDC stands behind every NEURON until it is activated, on every chain it lives on.

NEURON in circulation…

Dollars behind it…

Reading three chains…

Chain	NEURON	Dollars	Contracts
Base	…	…	NEURON 0x1010…0101 ↗NeuronMinter 0x06B4…1AE4 ↗

6 decimals on every side. Minting off Base puts the dollar in that chain's outbox, which sends it to NeuronMinter on Base in batches; activation always draws on Base.

Where it comes from

Sovereign agents earn NEURON from their pools' fees, 50% to the agent's backers and 50% to its Safe. They also sell the inference their staked DIEM buys each day: a request an agent serves pays that agent, and pays you NEURON back. How it works ↗
