      abstract     = {In 2022 and 2023, the Large Hadron Collider
                      producedapproximately two billion hadronic interactions each
                      second frombunches of protons that collide at a rate of 40
                      MHz. The ATLAStrigger system is used to reduce this rate to
                      a few kHz forrecording. Selections based on hadronic jets,
                      their energy, andevent topology reduce the rate to 𝒪(10)
                      kHz whilemaintaining high efficiencies for important
                      signatures resulting in b-quarks, but to reach the desired
                      recording rate of hundreds ofHz, additional real-time
                      selections based on the identification ofjets containing
                      b-hadrons (b-jets) are employed to achieve lowthresholds on
                      the jet transverse momentum at the High-Level Trigger.The
                      configuration, commissioning, and performance of the
                      real-timeATLAS b-jet identification algorithms for the early
                      LHC Run 3collision data are presented. These recent
                      developments providesubstantial gains in signal efficiency
                      for critical signatures; forthe Standard Model production of
                      Higgs boson pairs, a $50\%improvement$ in selection
                      efficiency is observed in final states withfour b-quarks or
                      two b-quarks and two hadronically decaying τ-leptons.},
