StateFlow stores object geometry, poses, semantic states, and camera settings as an editable 3D world, leaving the video model to handle visual refinement. In a 30-person study, its video previews received an overall rating of 4.5/5, though the system relies on several closed models and its code has not yet been released.

In a strong-to-weak test-time transfer experiment, stronger models wrote routing, format-checking, and deterministic-solving programs for a fixed smaller model without updating its weights. The best harness corrected about 83% of baseline errors, but performance depended heavily on theory-of-mind benchmarks whose patterns could be compiled into rules.

Liquid AI has released LFM2.5‑VL‑3B, a 3.1B-parameter model that adds screen grounding, layout OCR, multi-image understanding, and function calling. The company reports 228 tokens/s on an Apple M5 Max and roughly 11,000 tokens/s in high-concurrency throughput on a single H100, though the figures have yet to be independently reproduced.

A LoCoMo experiment found that general-purpose summaries preserve people and events but selectively discard dates, times, and durations. After an explicit instruction to preserve temporal anchors verbatim, judged accuracy on temporal questions rose from 15.6% to 47.0%.

CTBench requires agents to query interfaces modeled on real-world equipment and evaluates root-cause analysis and path reconstruction against expert-defined evidence steps. Although the best configuration raised path-reconstruction accuracy to 87.96%, root-cause analysis accuracy remained only 47.62%, with even less critical evidence retrieved.

OEIS Open tasks general-purpose language models with proving or disproving 492 integer-sequence conjectures under a fixed budget. The initial SafeVerify evaluation recorded 147 passes, but a second Lean verifier confirmed 144, highlighting how formal benchmarks remain sensitive to differences in specifications and checkers.

IBM’s VAKRA puts APIs, document retrieval, and natural-language policies into a single executable trajectory. Even the strongest model achieves only 50% to 70.4% full correctness across different API interfaces. When policies make questions unanswerable, some models’ success rates fall as low as 2.4%.

Using paired trajectories with and without skills, teams including Microsoft Research identified 125 functional failures and 182 cases of efficiency regression. The problem was usually not that the skill was irrelevant, but that the agent treated generic examples, validation checklists, or environment assumptions as hard task requirements.

InclusionAI has released the 7.9B-parameter Ling-3.0-tiny, which combines linear attention with sparse MoE and offers BF16, FP8, and INT4 weights. The company says FP8 reaches 86 to 90 tokens per second on an M4 Pro, but vLLM and Ollama support has yet to fully land in stable upstream releases.

DashArena evaluates model-generated interactive data dashboards across 234 open-ended tasks and uses a browser to replay the interaction workflows written by the models themselves. Adding interaction evidence raised agreement between an 8B vision judge and human preferences from 71.7% to 79.8%, yet even the best model achieved a full replay rate of only 73.3%.

IO Factory connects narrative planning, agent posting, platform exposure, audience-state updates, and baseline comparisons into a traceable simulation lifecycle. The system has completed runs with 100,000 simulated civilians and 10,000 operator agents, but all influence measurements derive from manually configured rules and LLM judges.

ReTree stores a search agent’s summaries, evidence sources, and revision history as a dependency tree. When new information overturns an earlier premise, the system returns to the node that introduced the error and deletes the affected branches. Results across four search benchmarks show that it both shortens per-step context and improves answers, though hard pruning may discard information that is not actually affected by the conflict.
