Treat this as a split decision. Celeris-1 makes more sense if knowledge is the priority or you want the cheaper token bill; GPT-4.1 is the better fit if you need the larger 1M context window.
Confidence note. This is a partial-evidence comparison with 0 shared benchmark results across 0 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Celeris-1 and GPT-4.1 finish on the same BenchAlign overall score, so this is less about a single winner and more about where the edge shows up. The BenchAlign headline says tie; the benchmark table is where the real choice happens.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $2.00 input / $6.00 output per 1M tokens for Celeris-1. GPT-4.1 gives you the larger context window at 1M, compared with 8K for Celeris-1.
