LoRA and RLVR: comparing strategies across domains
Published on January 3, 2026, this account compares practical PEFT strategies for multi-domain RLVR. In the reported experiments, averaging specialist LoRA weights and then continuing training outperformed the tested gating method.
On January 3, 2026, the author reported experiments on RL training across multiple domains and with specialist LoRAs. According to the account, joint training showed interference. The comparison covers practical PEFT strategies for RLVR; among the approaches tested, averaging specialist LoRA weights and then continuing training outperformed a gating approach.
This is a finding from the reported experiments, not a universal conclusion about training methods. To assess its scope, consult the original publication and check its experimental setup, metrics, and details of the compared approaches; the available summary does not specify these elements.
