The short version

  • Each has a real cost: Cohere aPI-only service with no self-hosted options for most users; Zoo the geometry engine runs entirely in Zoo's cloud and there is no offline mode, so an aircraft, a customer site with no guest wifi or an outage stops modelling work completely.
  • They diverge on capability: Cohere covers Generate, Zoo covers KCL scripting.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Cohere

  • API-only service with no self-hosted options for most users
  • Trial tier severely limited at 1,000 calls per month
  • Smaller context window compared to some competing APIs
  • Less emphasis on safety and alignment compared to competing APIs

Zoo

  • The geometry engine runs entirely in Zoo's cloud and there is no offline mode, so an aircraft, a customer site with no guest wifi or an outage stops modelling work completely.
  • STEP and SLDPRT import are still labelled experimental, which means the most common way of receiving a supplier or customer model is the least reliable path into the tool.
  • Drawing production, GD&T and tolerance annotation are far behind SolidWorks, Creo and NX, so most users still need a second package to release a manufacturing drawing.
  • Zookeeper is billed in reasoning minutes rather than per seat, so a team cannot forecast next month's bill from headcount the way it can with conventional CAD subscriptions.
  • The open source label applies only to the Design Studio client; the kernel that does the modelling is closed and hosted, so forking the repository does not give you a product you can run yourself.

Answered from the vendors’ own pages

Cohere: Does Cohere offer a free tier?

Yes. Cohere provides Trial API keys that allow 1,000 free API calls per month across all models and endpoints. Trial keys are rate-limited to 20 requests per minute for Chat endpoints and 5-10 requests per minute for other endpoints, and cannot be used for production or commercial purposes.

Zoo: Is Zoo the same company as KittyCAD?

Yes. KittyCAD renamed itself Zoo; the GitHub organisation is still KittyCAD and the scripting language KCL keeps the old initials.

Cohere: What is the cost structure for production use?

Cohere uses pay-as-you-go pricing based on tokens consumed. Costs vary by model: Command costs from 0.15 to 2.50 USD per 1M input tokens, with output tokens priced higher. Embed models cost 0.10 USD per 1M input tokens. Production keys have monthly billing with invoices at month-end or when charges reach 250 USD.

Source
Zoo: Can I use Zoo without an internet connection?

No. The geometry engine is a cloud service, so Design Studio needs a live connection to model anything.

Cohere: Can I self-host Cohere models?

No. Cohere operates as an API-only platform. However, enterprise customers can arrange dedicated or managed deployments through the Model Vault platform starting at 4.00 USD per hour with custom pricing for dedicated instances.

Source
Zoo: Is Design Studio free?

There is a genuine free tier with a small monthly allowance of AI reasoning and API calls. Paid plans start at $20 per month.

Cohere: What are the main differences between Cohere and Claude API?

Cohere excels in cost-effective NLP applications and retrieval-augmented generation (RAG) capabilities. Claude API emphasizes reasoning and safety with Constitutional AI training. Cohere's Command R+ offers similar performance to GPT-4 at 40-50 percent lower cost, while Claude focuses on factual accuracy and transparency.

Source
Zoo: Can I replace SolidWorks with Zoo?

Not for drawing release, large assemblies or GD&T. Teams typically use Zoo for programmatic part generation and keep an established package for production documentation.
