I have almost the same question as this, except I am using BibLatex. I would like the size of 'References' to be the same size as the title of 'Problem 1' of the subsection in the document. I tried the suggested change in the linked question, but it did not work for me.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[]{amsthm}
\usepackage[]{amssymb} %gives us the character \varnothing
\usepackage{amsmath} 
\usepackage{commath}
\usepackage{indentfirst}
\usepackage{hyperref} %lets us use links
\hypersetup{%
  bookmarksnumbered=true,%
  bookmarks=true,%
  colorlinks=true,%
  linkcolor=blue,%
  citecolor=blue,%
  filecolor=blue,%
  menucolor=blue,%
  urlcolor=blue,%
  pdfnewwindow=true} 
\usepackage[backend=biber,
style=alphabetic,
sorting=nyt]{biblatex}
\addbibresource{bib.bib}

\begin{document}

\newtheorem{lem}{Lemma} \newtheorem{thm}{Theorem} \newtheorem{cor}{Corollary}

\maketitle

\subsection*{Problem 1}

Blah blah blah blah.

\printbibliography

\end{document}

In an article-like class biblatex's default bibliography heading uses \section*.

If you want a \subsection*, you can use

\printbibliography[heading=subbibliography]

If you are not planning to use \sections at all, because their font size is too large for your liking, a better idea would be to make \section's font size smaller. (Using \subsection as highest sectioning level can lead to weird side effects with section numbering.) See Change size of section, subsection, subsubsection, paragraph and subparagraph title for help with that.
