Trade-offs
- Pricing is not published for most products
- Smaller ecosystem than the frontier labs
- Model capability still trails the largest international models on general benchmarks
Editors' review
Procurement, not benchmarks
Japanese enterprises choose a domestic model for contracting, data residency and supplier risk, not because it outperforms on an English benchmark. Sakana's customer list suggests that calculation is being made.
The router product is the more broadly interesting one: it concedes that no single model wins everything and treats selection as an engineering problem.
Verdict
Worth evaluating where a domestic supplier is a requirement. Compare on contract terms, not leaderboards.
