LevelField: Multimodal AI for Manufacturing Process Planning

LevelField is a 9-billion parameter multimodal model developed by Level AI, designed to assist process engineers with non-standard machining process planning. Built on the Qwen3.5-9B base model, it interprets 2D manufacturing drawings (PDF and image documents) to draft optimized machining routes.

Key Capabilities

• Drawing Interpretation: Extracts essential details like part names, drawing numbers, materials, dimensions, tolerances, surface roughness, and technical requirements from engineering drawings.
• Process Planning: Proposes operation sequences, identifies unsuitable processes, and suggests improvements based on reviewed machining requirements.
• Extensive Process Coverage: Supports 18 distinct manufacturing process types, including turning, milling, drilling, casting, forging, heat treatment, and inspection.
• Multilingual Support: Operates in both Chinese and English.

Good For

• Automating Initial Process Route Drafting: Significantly reduces the time required to draft process routes, with reported reductions of approximately 60% in pilot customer usage.
• Assisting Process Engineers: Provides proposals that require engineering review, acting as a powerful assistant rather than a fully autonomous system.
• Interpreting Complex Drawings: Helps extract information from various drawing formats, though users should carefully check small annotations or ambiguous geometry.

LevelField was fine-tuned and reinforced using 100,000 manufacturing drawings and process sheets from 16 factories, with validation from 36 experienced process engineers. Internal evaluations report over 95% alignment between the model's process reasoning and senior engineers' decisions. It is released under the Apache 2.0 license, permitting commercial use.
