Shanghai-based startup EBKernel unveiled Cog-WM 1.0 at the embodied brain intelligence session during the Puzhang Innovation Forum in 2026. The company positions this release as a cognitive world model built on latent space prediction rather than pixel reproduction.
According to the company's statement, this architecture borrows organizational concepts from human cognitive maps, such as selective memory updating, goal-conditioned encoding, and multi-horizon prediction. These ideas are combined with a JEPA-style joint embedding objective, enabling robots to plan using abstract spatial and state features instead of reconstructing raw frames.
In terms of navigation, the Cog-WM Nav 1.0 model was tested without using a pre-built map. On a subset of HM3D-ObjectNav, EBKernel reported an increase in success rate from 78.50% to 86.89% compared to the BSC-Nav baseline published in Nature Communications. This represents an absolute gain of 8.39 points (approximately 10.7% relative), and the SPL metric increased from 47.70 to 48.35.
The navigation component maintains explicit spatial memory and predicts subgoals for exploration in the latent space. It then balances between goal semantics and path cost, which is particularly useful when the target is outside the current field of view and the robot needs to decide where to look next.
The manipulation branch, Cog-WM Manip 1.0, trains multi-scale state and value-modulated experience prediction, providing a link between short-horizon action effects and long-term task progress. Using a unified replay protocol, EBKernel claims that the model outperforms massively pre-trained baseline models like pi0.5 by approximately 16% across three main manipulation datasets, including more complex RoboTwin 2.0 settings.
Analysis of component influence on LIBERO-Plus showed an additive effect: the policy alone achieved nearly 80%, local prediction reached 81.6%, multi-horizon prediction reached 82.0%, and the full system reached 84.6%.
The company states deployment capabilities cover wheeled and quadrupedal humanoids for mapless navigation, route planning, spatio-temporal memory retrieval, spatial question answering (QA), and object searching. Manipulation was tested on wheeled humanoid bodies, while quadrupedal navigation was noted on client objects for inspection or patrolling.
EBKernel, founded in mid-2025, promotes a product thesis centered on lifelong learning with low data requirements and high generalization ability. However, independent outdoor durability metrics and long-horizon field results remain within the confines of the company's internal benchmarks, so laboratories are advised to consider the published SR metrics and manipulation changes as the primary comparison set until third-party work emerges.
