Seattle-based Carbon Robotics has introduced a new AI model, the Large Plant Model (LPM), capable of instantly identifying plant species to combat weeds, according to TechCrunch.
The company develops LaserWeeder robots, which use lasers to weed fields of agricultural crops. Its new LLM has been trained on over 150 million photos and data collected by the company’s machines across more than 100 farms in 15 countries.
The model now underpins Carbon AI, the AI system that acts as the brain for autonomous bots.
Carbon Robotics CEO Paul Mikesell explained that before LPM, the company had to create new data labels to retrain machines whenever a new weed species emerged, a process that took about 24 hours.
Now, the model can instantly recognize a new harmful plant species, even if it has not encountered it before.
Founded in 2018, Carbon Robotics began developing LPM shortly after delivering its first machines in 2022.
The new system will be available to the company’s clients following a software update. It will allow farmers to instruct the machine on what to destroy and what to protect by selecting photographs.
Carbon Robotics has raised over $185 million in venture capital.
In February 2025, Figure introduced its proprietary artificial intelligence, Helix, for integration with robots. According to its creators, the model can “reason like a human.”
