Frequently Asked Questions (3)
Can I compare Celeris-1 and LFM2.5-ColBERT-350M on BenchLM yet?
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
Why does this comparison show “coming soon”?
BenchLM only shows category winners and benchmark-level calls when we have sourced results that can be compared fairly. For these models, the public benchmark coverage is not complete enough yet.
What data is available for Celeris-1 and LFM2.5-ColBERT-350M today?
Celeris-1: $2.00 input / $6.00 output per 1M tokens LFM2.5-ColBERT-350M: $0.00 input / $0.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
