@maksym_andr Solving PTB should be rather easy, imo

@xeophon it depends on *how* PTB gets solved. i think it should still be pretty hard in our original framing, in which the main prompt remains generic, i.e., without hardcoded methods (e.g., "Use SFT and then RL") or datasets (e.g., use OpenThoughts) and where the agent has only 10h.
