A new survey paper by Chef Robotics Senior Staff AI Research Scientist Inkyu Sa maps the relatively new field of world models and world-action models and evaluates which modeling approaches are best suited for robotics, autonomous driving, reinforcement learning, games, and general-purpose simulation.

A new survey paper by Chef Robotics Senior Staff AI Research Scientist Inkyu Sa examines the rapidly evolving field through one of robotics' hardest challenges: bimanual manipulation, or coordinating two arms to complete tasks such as folding fabric, assembling objects, and handling deformable materials.

We built ValueFormer, a critic that watches the cameras our policy uses and provides feedback on policy performance that behavior cloning can’t provide. Folded back into policy training, ValueFormer shows early on-robot success: two different critic-derived weightings each increased successful burger assembly from 70% to 85%.

Every serving a Chef robot makes generates data that improves the next serving. We call this the data flywheel. With more than 120 million meals in production, Chef Robotics has built the world’s largest dataset of real food manipulation, and every production run widens that lead.

Food assembly robots provide a labor-equivalent solution for processes that have traditionally been difficult to automate. They also enable food manufacturers to reduce carbon emissions. Here’s how.

Chef’s AI-enabled robots deliver ROI for food manufacturers through five levers: lower labor costs, reduced food waste, higher throughput, and improved safety, all through a robotics-as-a-service (RaaS) model.

For most of robotics history, a robot was a programmed machine. This approach works well in automotive manufacturing, where robots perform the same welding task millions of times in a perfectly controlled environment. It doesn’t work for food manufacturing. What’s changing robotics and its impact on the food industry is that robots can now learn new tasks on their own.

We’ve been teaching a physical AI system to assemble a burger in under a minute. Part 3 of our blog series explores how Chef’s data flywheel helped improve performance from 75% to 91.3% success rate with just 4.5% more training data.

Chef robots pick and deposit food ingredients thousands of times per hour using pneumatic grippers. Gripper opening speed directly affects placement quality and throughput, but pneumatic systems vary across robots and degrade over time, making manual tuning unreliable. We built a layered system—using a flowmeter, regression, a neural network, and online adaptive control—to measure what the gripper actually does and automatically correct for it, without manual intervention.

Chef’s engineering team developed CLUTCH (computationally learn and understand topology-based clasp height), a neural network-based pick depth estimator for robotic food assembly. Unlike the existing geometric model VPD (volumetric pick depth), CLUTCH ingests an ingredient point cloud and target weight to predict utensil pick depth directly from data.

Chef's physical AI models handle breakfast tray assembly by combining piece-picking, scooping, and component insertion—placing sausage patties and hash browns, portioning oatmeal and grits by weight, and dropping in sauce packets, all at production speed. The solution works across a wide range of breakfast ingredients and tray formats without requiring changes to existing production line infrastructure.

There’s a major debate in physical AI right now: will generalist models and embodiments outperform vertically integrated solutions? In our view, intelligence will become increasingly shared, while embodiments will remain highly specialized.

Chef's conveyor companion box required physical hardware for every full-stack test path. To solve this, we built a hardware abstraction layer and an in-process PLC model that lets the complete deposit-and-go sequencing stack run on a developer laptop with zero hardware in the loop, allowing engineers to catch synchronization and timing bugs before they reach a live customer environment.

We’ve been teaching a physical AI system to build a complete burrito bowl with rice, corn, beans, chicken, lettuce, and cheese in under two minutes. The same Food Foundation Model architecture behind our burger assembly work has learned an entirely new skill from just over 25 hours of demonstration using regular kitchen utensils.

Ingredient onboarding is a fundamentally messy, real-world problem, but with the right combination of structured data, production feedback, and LLM-based reasoning, it becomes tractable at scale.

Chef’s deposit assist is a hardware attachment that attaches to Chef’s existing end effector to improve deposit accuracy into small compartments and inserts for scoopable ingredients like shredded cheese, finely chopped vegetables, and dry mixes. It guides deposits into the target compartment and clears leftover ingredients between utensils before each deposit, reducing spillage into adjacent compartments. The module is compatible with Chef’s existing robotic hardware and requires no changes to production line infrastructure, making it straightforward to deploy across food manufacturing lines.

With the advent of physical AI and imitation learning, Chef’s AI team is developing a bi-manual physical AI system for prep table food assembly.

Chef’s AI-enabled robots can now automate secondary packaging and kitting assembly for consumer-packaged goods lines, picking and placing discrete items—sauce sachets, seasoning packets, cutlery kits, garnish toppers, and other irregular inclusions—into cups, bowls, and trays. These applications use Chef’s existing piece-picking capability, enabling food manufacturers to achieve higher throughput, lower labor dependency, and consistent presentation across CPG assembly lines.

Modern vision-language-action models (VLAs) predict actions in chunks, but each new chunk starts from a stale observation, causing visible shaking at chunk boundaries. We traced this problem back to three compounding delay sources, measured each via system identification, and shifted the training target to compensate.

Chef’s physical AI models automate tray assembly for baked goods, placing cookies and other baked products into trays and packaging containers quickly and precisely without damaging them. For food manufacturers evaluating bakery equipment, bakery machines, and bakery systems, Chef’s solution can help increase throughput, reduce labor dependency, and achieve consistent presentation on production lines.

We’ve been teaching a physical AI system to pick, place, and stack a complete burger with buns, patty, cheese, lettuce, and tomato in under a minute. The technology that made this possible, our Food Manipulation Model (FFM), learned this task by demonstration with just over 26 hours of training data.

Chef’s AI-enabled robots can now automate produce packing, placing discrete items such as oranges, apples, and pears into clamshell packages and snack boxes, and portioning scoopable produce like corn into trays before packaging. These applications use Chef’s existing piece-picking and scooping capabilities, enabling food manufacturers to achieve higher throughput, lower labor dependency, and consistent portion presentation across produce packing lines.

Today, we’re thrilled to announce that Chef robots have completed 100 million servings in production at customer facilities—an order of magnitude more than all other food robotics companies combined. This is also an opportunity to reflect on why production servings are so important in food robotics, how we went from zero to eight zeros, and what happens next.

Chef’s AI-enabled robots can now automate meatpacking tasks, assembling a variety of raw, frozen, and precooked proteins such as pork loin filets, chicken breasts, lamb chops, steaks, sausage links, and bratwursts onto trays before packaging. These meatpacking tasks use Chef’s existing piece-picking capability, offering food manufacturers higher throughput, lower labor dependency, and consistent portion presentation across meatpacking and tray assembly lines.

Chef robots use AI-powered vision to detect and place ingredients on flatbreads such as tortillas, wraps, lavash, burger buns, and pizza bases. By combining large-scale trained models with adaptive placement strategies, they maintain precision and high throughput across production lines without requiring changes to existing infrastructure.

This blog explores what RaaS is, why it can be a beneficial business model for physical AI companies and their customers, and how RaaS has been reshaping automation in the food industry.

Robot-to-robot (R2R) communication allows multiple Chef robots to coordinate ingredient deposits on a shared conveyor belt, achieving higher throughput without sacrificing precision. It operates wirelessly, is easy to deploy, ensures faster reactions on moving conveyors, and reduces spillage and missed trays on high-speed production lines.

Chef robots can communicate with all types of food manufacturing conveyors. Using the conveyor companion box, the robots can read and dynamically adjust conveyor speed to maximize throughput and minimize missed trays, deposit ingredients even more precisely onto conveyors while minimizing spillage, and react to sudden conveyor starts or stops without requiring any changes to existing line infrastructure.

Chef's AI-enabled robots use shielded utensils and deep learning vision models to precisely place ingredients into small compartments and inserts within a meal tray.
