Resolves YES if a language model is released before January 1st 2026, that:

1. Has freely accessible weights, meaning the general public can download it and run it locally, regardless of additional restrictions.
2. Is explicitly described as having less than 10 billion parameters. (If the actual parameter number is less than 10B and was e.g. rounded up, this doesn't count as being under 10B.)
3. Achieves an Arena Score on http://lmarena.ai/leaderboard greater than the score of Claude 3.5 Haiku 2024-10-22, with both scores measured at the same point in time.

In the event that the way Arena Scores are calculated changes significantly or that specific Haiku model is no longer ranked before EOY2025 (I would be very surprised if this happens), I will try to find a suitable replacement criteria that traders can agree is fair. If no such criteria can be found, this market will N/A.
