How does pricing compare?

Thunder Compute: Paid (per-minute instances, per-second sandboxes). Thunder Compute bills instances per minute while running and sandboxes per second. Published instance rates: RTX A6000 $0.35/GPU-hour, L40 $0.79, A100 80GB $1.09, H100 SXM $3.20, with extra vCPUs at $0.04/vCPU-hour. Sandbox rates are $2.95/GPU-hour for H100 SXM and $1.95/GPU-hour for A100 80GB plus vCPU, memory, and storage components. Instance disk storage is $0.219/GB per month (first 100 GB per GPU included), snapshots are $0.05/GB per month, and data egress is free. Grilled specifically: rates change over time, so verify on the pricing page. Union.ai: Freemium, Contact for Pricing. Freemium-style entry with a free open-source Flyte option. The managed Team plan starts at a $950/month minimum, fully credited to usage, with the first month free and no card required at signup. Consumption is metered on actions, vCPU-hours, memory GB-hours and GPU-hours across published volume bands. Enterprise is custom-priced on an annual commit with volume discounts, and optional Union-managed clusters cost $500 per cluster per month, capped at $2,500.

Thunder Compute

Low-cost cloud GPUs with per-minute instances and per-second sandboxes for AI workloads.

Persistent GPU instances

Launch RTX A6000, L40, A100 80GB, or H100 SXM machines, often ready to SSH into within minutes, and pay only while they run.

Per-second GPU sandboxes

Spin up isolated Ubuntu VMs with or without a GPU for RL rollouts, evals, and CI, billed per second and scaled to zero between runs.

Developer-first tooling

A CLI, VS Code extension, MCP server, and REST API let you drive infrastructure from a terminal, an editor, an AI agent, or your own services.

Snapshots and persistent storage

Save an instance disk as a snapshot and restore it later, so you can pause experiments without leaving machines running.

Strengths & Pros

+Aggressive pricing versus hyperscalers: published H100 rates around $3.20/GPU-hour against $6+ at major clouds.
+Two billing models that match two real workloads: per-minute persistent instances and per-second ephemeral sandboxes.
+No egress fees and no preemption, which removes two common sources of surprise cost and interruption.
+Real developer surface area: CLI, VS Code extension, MCP server, REST API, and templates.

Limitations

–GPU availability can fluctuate, so a particular type may be sold out when you try to launch it.
–Sandbox access is requested through sales rather than being fully self-serve at sign-up.
–The platform's GPU catalog is narrower than the largest hyperscalers, which offer a wider range of accelerator families.

Union.ai

The durable AI runtime that runs in your cloud, not ours

Durable execution engine

Tasks, traces and artifacts survive infrastructure failure. Runs fork, recover and replay from the last good step instead of starting over, with retries and caching handled by the runtime.

AI factory and artifact lineage

Named, typed and versioned artifacts wire teams together, with lineage showing which run produced each version and which downstream tasks consume it.

Sovereign, bring-your-own-cloud deployment

Run the control plane in Union's cloud while workloads execute on clusters in your AWS, GCP, Azure or neocloud account, under your own security perimeter.

Production agents and agent traceability

Bring OpenAI, Claude, PydanticAI or CrewAI agents; each turn is traced and sandboxed in ephemeral containers, MCP servers and human approvals supported.

Strengths & Pros

+Durable execution means long training, inference and agent runs survive node loss, spot reclamation and API rate limits
+Bring-your-own-cloud architecture keeps data, models and secrets inside your own security perimeter
+Backed by the creators of Flyte, so the open-source engine and the managed platform evolve together
