TypeLLM adds type-safe, schema-guaranteed generation to LLMs without touching weights

TypeLLM brings type-safe generation to existing autoregressive LLMs without changing architecture or weights, inspired by TypeSafe AI's Jev and built on SGLang. Key features: no out-of-schema hallucinations via JSON Schema guarantees, negligible output-token cost (single-token categorical selection, bounded numeric decoding), shared-prefix KV cache reuse, dependency-aware execution (sequential, batched, or dependson graphs), and support for richer interaction patterns beyond independent typed decisions — all while preserving the model's native thinking and free-form generation.
