Rules
Resolves YES if someone (likely a team at Anthropic) confirms that Mythos 5 (or Fable 5) probably is at least as much of an alignment faker (aka "gradient hacker") as Opus 3.
- Resolves NO if someone confirms that this is not the case
- This means that Mythos strategically complies with harmful requests in RL specifically in order to preserve its values.
- If nobody bothers to check then in a year resolves N/A since by that point we'll be on Claude 7 or smth
- Note that this market is probably biased towards YES since a negative result is less likely to be published
