Fill-in-the-Middle (FIM) and Inline Code Completion in Production: Architecture, Prefix-Suffix Context Windows, Speculative Decoding, and Sub-50ms Serving Latencies
Fill-in-the-Middle (FIM) and Inline Code Completion in Production: Architecture, Prefix-Suffix Context Windows, Speculative Decoding, and Sub-50ms Serving Latencies Inline code completion is the most latency-sensitive deployment of large language models in production software engineering. Unlike conversational assistants or background agentic batch jobs, inline code completion operates directly inside an active editor typing loop. Developers type at speeds ranging from 40 to 120 words per minut
