OpenAI's GPT-5.5 Pro currently leads the FrontierMath benchmark—a test of research-level math problems across Tiers 1-4—with 52.4% on Tiers 1-3 and 39.6% on the hardest Tier 4, per its April 2026 release, outpacing rivals like Anthropic's Claude Opus 4.7. Trader consensus reflects rapid iteration in OpenAI's model family, but sentiment tempered by Epoch AI's May 11 announcement of a review after GPT-5.5 flagged fatal errors in about one-third of problems, pausing leaderboard updates. DeepMind's multi-agent system recently hit 47.9% on Tier 4, heightening competition. With six weeks to June 30, watch for GPT-5.6 previews or revised scores that could swing implied probabilities on threshold achievements.
