Questions
What is the difference between bespoke-nimble-9b and laya?
bespoke-nimble-9b is from Bespoke Labs and laya from Convai Innovations. bespoke-nimble-9b has open weights and a hosted API; laya has open weights you can download and run. Both answer choice, noul, score, classify and route questions. bespoke-nimble-9b reads up to 8K tokens of state, against 512 tokens for laya. laya is the smaller model, at 421M parameters to 9.0B.
Which is more accurate, bespoke-nimble-9b or laya?
Only bespoke-nimble-9b publishes an accuracy figure (90.1% on Bespoke held-out set (324 examples)); laya does not, so there is no comparison to make without your own test.
Which is cheaper, bespoke-nimble-9b or laya?
bespoke-nimble-9b: Hosted, price not published, or free to self-host. laya: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, bespoke-nimble-9b or laya?
By their publishers’ figures, laya answers in about 39.5 ms at the median and bespoke-nimble-9b in about 106 ms — measured on different hardware, so treat it as a rough guide.
Can I run bespoke-nimble-9b or laya locally?
Yes, both: systemone pull bespoke-labs/bespoke-nimble-9b and systemone pull convai-innovations/laya download the weights.
