The short version

  • Only Cerebrium has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cerebrium free Hobby tier limited to 3 apps and 5 GPU concurrency; Writer pricing is not publicly disclosed and requires a sales conversation, unlike consumer AI writing tools.
  • They diverge on capability: Cerebrium covers Ultra-fast cold starts, Writer covers Palmyra LLMs.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cerebrium

  • Free Hobby tier limited to 3 apps and 5 GPU concurrency
  • Standard plan at $100/month required for production deployments
  • Per-second compute pricing requires continuous cost monitoring
  • Storage costs add up for large model files

Writer

  • Pricing is not publicly disclosed and requires a sales conversation, unlike consumer AI writing tools.
  • Its proprietary Palmyra models are less widely benchmarked and documented than general-purpose models like GPT or Claude.
  • Primarily positioned for large enterprises, making it less accessible or cost-effective for individuals and small teams.

Answered from the vendors’ own pages

Cerebrium: Is Cerebrium only for inference or can it train models?

Cerebrium supports both inference serving and model training with hyperparameter sweeps. It enables deployment of voice agents, LLMs, video models, and other AI applications.

Source
Writer: What does Writer cost?

Writer does not publish prices. There are two tiers: Starter, for teams up to five users, with a 14-day free trial and no card required, and Enterprise, which is contact-sales and adds unlimited users and teams.

Source
Cerebrium: How do the cold starts compare to other platforms?

Cerebrium achieves 2-4 second cold starts through memory and GPU snapshotting, significantly faster than traditional 30+ second cold boots. This is competitive with platforms like Beam Cloud.

Source
Writer: What is the difference between Pro and Lite seats?

Pro is the standard paid seat, with full access to create, customise and automate workflows. Lite seats exist only on Enterprise, letting invited users view and run existing playbooks with limited monthly Agent use before needing a Pro seat.
