Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CodeSandbox
- Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
- Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
- Public sandboxes are visible to others by default, which is not ideal for proprietary code.
Together AI
- Fine tuning carries a minimum charge of $4.00 per job regardless of dataset size
- Reserved GPU commitments beyond 180 days are priced by contacting sales with no published rate
- Volume and enterprise discounts are quote only with no published threshold
- Reserved dedicated inference pricing is contact sales while only on demand rates of $5.49 to $8.99 per GPU hour are published
