Ahead of a former leader
Google DeepMind’s fire hedgehog led the tournament on 28 September. On 2 November, RSO-F scored above it when both were measured on resolved dataset questions.
The tournament also scores prediction-market questions. RSO-F’s lead over fire hedgehog was on the dataset comparison.
Reading the result
Third among named teams counts each team once, using its highest-scoring entry. The full leaderboard also includes anonymous submissions and multiple configurations from the same team. RSO-F’s entry rank in that table is 18th out of 616.
ForecastBench adjusts for differences in question difficulty. RSO-F’s 95% confidence interval was 62.9 to 67.4, overlapping those of the DeepMind entries.
7 November update
In the revised preliminary table, RSO-F scored 64.5 on 246 questions, fifth among named teams and joint 24th among all 616 entries. The table above preserves the 2 November result. We will report RSO-F’s tournament result separately.
