About
ICLR is one of the premier venues for deep learning and representation learning research, run as a double-blind peer-reviewed conference with a notably competitive acceptance process. The 2026 edition in Rio de Janeiro saw submissions surge 68 percent year-over-year, while in-person attendance tightened around a more selective accepted-paper crowd.

Our verdict
Scored 84 out of 100
ICLR consistently delivers high-signal research content across representation learning, reasoning, and agents, and the 2026 edition in Rio was praised for the quality of researcher interactions despite a drop in overall in-person attendance. The shift in research focus from foundation model refinement toward reasoning and agentic behavior made the accepted-paper slate particularly valuable. The main friction points were venue logistics and a notable security breach in the review system that exposed author and reviewer identities for a large submission subset.
Worth it for
- Acceptance rate dropped to 27 percent in 2026 (from 32 percent in 2025), meaning the accepted paper track represents genuinely high-bar research
- Attendees consistently report it is easy to meet top researchers across subfields in an informal setting, with strong hallway-track density
- Workshops program is broad and deep, spanning emerging subfields before they reach the main track
Watch out for
- A 2026 security incident exposed author, reviewer, and area chair identities via the OpenReview API, raising ongoing concerns about review integrity
- In-person attendance fell sharply in 2026 (7,054 vs 10,435 in 2025 Singapore), limiting spontaneous networking volume relative to prior years
