  GRS1915+105 is a very peculiar black hole binary that exhibits
accretion-related states that are not observed in any other stellar-mass black
hole system. One of these states, however -- referred to as the plateau state
-- may be related to the canonical hard state of black hole X-ray binaries.
Both the plateau and hard state are associated with steady, relatively lower
X-ray emission and flat/inverted radio emission, that is sometimes resolved
into compact, self-absorbed jets. However, while generally black hole binaries
quench their jets when the luminosity becomes too high, GRS1915+105 seems to
sustain them despite the fact that it accretes at near- or super-Eddington
rates. In order to investigate the relationship between the plateau and the
hard state, we fit two multi-wavelength observations using a steady-state
outflow-dominated model, developed for hard state black hole binaries. The data
sets consist of quasi-simultaneous observations in radio, near-infrared and
X-ray bands. Interestingly, we find both significant differences between the
two plateau states, as well as between the best-fit model parameters and those
representative of the hard state. We discuss our interpretation of these
results, and the possible implications for GRS 1915+105's relationship to
canonical black hole candidates.
