Workflash
Alpha & beta waitlist · Zero-idle GPU cloud

On-demand cloud GPUs for local AI workflows

Turn the avatar, voice, speech, and ComfyUI pipelines running on your workstation into instant HTTPS and WebSocket APIs. Wake pre-warmed GPU snapshots in seconds, stream media as it generates, and pay $0.00/hr the moment traffic stops.

Built for real-time avatars, speech, and creative pipelines

Standard serverless platforms buffer whole responses and stall on cold boots. Workflash streams audio frames, video segments, and progress events as they generate.

Workstation & ComfyUI Cloud Bursting

Keep your local RTX workstation and ComfyUI canvas at zero marginal cloud cost when free, and overflow heavy graphs to on-demand cloud GPUs when busy.

gpu-lease failover · SHA-256 asset staging

Two clean planes, zero GPU cloud lock-in

Keep provider plumbing out of your product code. Call one streaming execution gateway while governing deployments, client workspaces, and spend caps in one console.

Your Product or WorkstationWeb Apps, Agents & Local ComfyUI

Use local RTX capacity first via gpu-lease, then burst seamlessly over HTTPS or WebSockets when local VRAM is busy.

Workflash Platformapi.workflash.run & workflash.app

Verifies scoped wfl_* keys, enforces hard USD caps, stages SHA-256 media in R2, and routes traffic without exposing raw provider URLs.

Single-session leaseMicro-USD ledger
Ephemeral Compute PoolWarm GPU & CPU Snapshots

Restores H100, L40S, A10G, or CPU workers from memory snapshots in seconds, streams output live, and scales back to $0.00/hr.

$0.00/hr when idle

Memory snapshots, not cold container waits

Weights and CUDA state wake directly from pre-warmed snapshots instead of re-pulling multi-gigabyte images on traffic spikes.

Hard USD spend caps on every key & workspace

Enforce daily and monthly dollar budgets in real time with micro-USD GPU metering—preventing runaway retry loops from ever becoming surprise bills.

One stable API across GPU clouds

Applications call api.workflash.run over HTTPS and WebSockets—never raw provider URLs—so hardware profiles can move across GPU clouds without code edits.

Built for developers and coding agents

Declare workflows once in workflash.yaml. Agents and teams can validate contracts, stage SHA-256 weights, probe cold wake, and track cost per call.
