Braintrust vs Helicone
Latest verified observations from the BizOps AI ledger. Empty cells mean the metric does not apply or the ledger hasn't captured it yet — never a guess.
| Consumption metric | Braintrust | Helicone |
|---|---|---|
| Input tokens ($ / 1M) | $0.4 | — |
| Output tokens ($ / 1M) | $0.06 | — |
| Vector storage ($ / GB / mo) | $4 | — |
| Free-tier credit ($ / mo) | $10 | — |
| Free storage (GB) | — | 1 GB |
| 12-signal BizOps Score (method) | — | 44 |
Output : Input margin ratio
Where the bar crosses zero is parity; the further it extends toward Output, the more a generation-heavy workload costs beyond what the input rate alone suggests.
Token efficiency changes the real price
Braintrust bills output at 0.1× its input rate. Chatty, generation-heavy agents feel that multiplier directly.
Tokenizer tax: the same sentence is not the same number of tokens
everywhere. Non-English text typically needs 20–30% more tokens for identical content,
so a nominally cheaper $/1M rate can cost more per delivered character in multilingual workloads.
