Neither tool offers a free tier. Claude Mythos Preview starts at Invite only, Perplexity Computer at $20. Plan to budget for whichever you pick. The cheap tier usually caps out faster than buyers expect, so look at what the entry plan actually includes -- both vendors have raised list prices in 2026 and the limits are where most of the cost surprise lives.

By use case: pick Claude Mythos Preview when partner organizations in project glasswing doing cybersecurity research, defensive red-teaming, threat intelligence, or large-scale vulnerability triage.

If you're squarely in Perplexity Computer's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Claude Mythos Preview's lane, the score gap matters less than the fit.
