Frequently asked questions
Is OpenAI or Cohere cheaper?
It depends which tier you need. Cohere has the lower entry price, but both run a range from budget to frontier models, so the fair comparison is tier against tier rather than vendor against vendor. Price the specific models you would actually call; the table above shows each side’s floor and ceiling.
Should I use OpenAI or Cohere?
Neither wins outright. Shortlist by the capability tier your workload needs, then compare the specific models on price, context window and benchmark evidence. Multi-vendor setups are common precisely because the cheapest adequate model for one task is rarely the same vendor as for another.
Where do these OpenAI and Cohere prices come from?
Each provider’s published rates, as tracked in our pricing index. Blended figures weight input at 70 per cent and output at 30 per cent and are calculated comparison metrics rather than published prices. Counts cover text-generation models only, excluding retired SKUs, embeddings and non-text products.
