Share idle AI model capacity and put every call to work

Fasten Share connects model-capacity producers with callers. Publish local models, private deployments, or compatible APIs you are allowed to share while the platform handles discovery, streaming routing, metering, and credit settlement.

Only connect model capacity you are authorized to use and share, and follow the upstream provider terms.

One client, two ways to participate

Provide model capacity or call shared nodes

Producers and consumers use the same desktop client with clearly separated credentials, credits, and workflows.

PRODUCER

As a producer

Connect a model backend you are allowed to share and earn producer credits after successful consumer calls.

  • Local models, private deployments, and compatible online APIs
  • Upstream API keys are stored and injected locally, never distributed to consumers
  • Control models, concurrency, credit multiplier, and sharing status
Read the producer guide
CONSUMER

As a consumer

Find online model nodes, select a producer, and connect AI tools or API clients through one generated endpoint.

  • Discover nodes by model, protocol, rating, and availability
  • Generate a consumer API key and compatible endpoint
  • Streaming responses, follows, and monthly ratings

From publishing to inference

How the platform works

Consumers never receive a producer’s upstream key. Inference requests and responses pass through the Fasten Share service for routing, metering, and settlement.

  1. 01

    Connect a backend

    Configure the protocol, base URL, models, and locally stored credential in the client.

  2. 02

    Publish a healthy node

    The producer opens an outbound connection and runs health checks so unhealthy backends leave discovery.

  3. 03

    Choose and call

    A consumer finds a node and sends standard HTTP or streaming requests to the generated Fasten Share endpoint.

  4. 04

    Meter and settle

    The service meters actual forwarded usage and tracks consumer and producer credits separately.

Works with your existing setup

Connect local models, online APIs, and popular AI tools

Exact compatibility depends on the protocol and tool capabilities published by each producer. The current client UI is authoritative.

Core capabilities

The complete path from sharing to inference

01

One compatible entry point

Consumers call the endpoint generated by Fasten Share without receiving a producer’s original upstream credential.

02

Local and online backends

Connect Ollama, LM Studio, vLLM, and OpenAI-, Anthropic-, or Azure OpenAI-style APIs.

03

Continuous health checks

Periodic checks reduce the exposure of nodes with authentication failures, exhausted quota, or unavailable endpoints.

04

Discovery and trust signals

Search by model and protocol, then use availability, follows, and recent three-month ratings to choose a producer.

05

Streaming transport

The platform forwards requests and responses between consumer HTTP and the producer’s outbound connection, including streaming content.

06

Authoritative metering

Actual forwarded data is metered centrally while consumer and producer credits remain separate.

Security boundary

Keys stay local, and the traffic path stays clear

A producer’s upstream API key is stored by the local client and injected only when it calls the model backend. It is not sent to consumers or the Fasten Share service. Consumer prompts and model responses do pass through the service to enable routing, metering, and settlement, so always use the official HTTPS domain.

1

Inspect the open-source client

The producer client is MIT-licensed, including the local credential and request-forwarding implementation.

2

Stay in control of sharing

Adjust concurrency and the credit multiplier, stop an individual backend, or take the client offline at any time.

3

Producers confirm sharing rights

Do not connect capacity you may not forward or that violates upstream account, subscription, or commercial-use terms.

Common questions before you start

Is a producer’s upstream API key uploaded?

No. The upstream credential stays on the producer device and is injected by the local client when it calls the backend. Consumers and the Fasten Share service do not receive it.

Do prompts and model responses pass through Fasten Share?

Yes. The service performs discovery, routing, authoritative metering, and credit settlement, so prompts and responses are forwarded through the official HTTPS service.

What model capacity can I share?

You can connect local models, private deployments, or compatible online APIs you are authorized to share. Exact protocols and models depend on current client support and your configuration.

Do producer credits guarantee cash income?

No. Producer credits come from successful usage. Withdrawal eligibility, exchange rates, thresholds, review, and payout rules are those shown in the client when you apply; no fixed income is promised.

How does a consumer call a shared model?

Sign in, create a consumer API key, find and select a model node, then copy its generated endpoint or use the tool configuration assistant.

Which operating systems are supported?

Desktop packages are published for Windows, macOS, and Linux. Check the download page for currently available builds and versions.
