Which is better, Morph or Freestyle?
It depends on how you fork. For agents that wait on a model, Runtime bills measured CPU. The 2 vCPU benchmark costs $0.64 there, against $1.67 on Morph and $2.25 on Freestyle. Its forks make up to 100 copies, with memory kept. Pick Morph to branch one machine into hundreds of replicas. Pick Freestyle if a fork must never pause the source VM.
At a glance
| Morph | Freestyle | Runtime | |
|---|---|---|---|
| Isolation | Full virtual machines | Full Linux virtual machines | Firecracker microVM, own kernel |
| Price | $0.05 per MCU-hour: 1 vCPU, 4 GB or 16 GB of disk | $0.04032 per vCPU-hour, $0.0129 per GiB-hour | Measured CPU and reserved memory |
| Forks | Infinibranch, to hundreds of replicas | Live forks without pausing | Up to 100 running copies |
| Plan | Developer free with no credit; Team $40, Scale $250 a month | Free, Hobby $50, Pro $500 a month | None; prepaid credit from $10 |
Forks at different scales
Morph's Infinibranch turns one running machine into hundreds of replicas. It is made for tree search over agent actions. Freestyle clones a running VM without pausing it. A Runtime fork pauses the source for the capture, wakes it before it returns, and creates up to 100 running copies. The copies have memory and processes, and they start from one warmed-up state.
Cost for the same job
2 vCPU and 4 GB (2 MCUs on Morph), 60 seconds, 20 CPU-seconds, 1,000 runs, with Freestyle's 32 GiB disk:
- Size
- 1,000 × 60 s / 3,600 × 2 MCU × $0.05
- $1.67
- CPU
- 1,000 × 60 s / 3,600 × 2 × $0.04032
- $1.34
- Memory
- 1,000 × 60 s / 3,600 × 4 × $0.0129
- $0.86
- Disk
- 1,000 × 60 s / 3,600 × 32 × $0.000086
- $0.05
- CPU
- 1,000 × 20 s / 3,600 × $0.025
- $0.14
- Memory
- 1,000 × 60 s / 3,600 × 4 × $0.0075
- $0.50
With both CPUs busy for the whole minute, the job costs $1.67 on Morph, $2.25 on Freestyle, and $1.33 on Runtime.
Which one to pick
- Morph for branching into hundreds of replicas.
- Freestyle for forks that never pause the source.
- Runtime for the lowest bill, with forks when 100 copies are enough.

Runtime Cloud
Runtime costs 62% less than Morph and 72% less than Freestyle for an agent that waits. On 1,000 one-minute runs of a 2 vCPU, 4 GiB sandbox with 20 CPU-seconds of work each, Morph costs $1.67, Freestyle $2.25, and Runtime $0.64.
