GLM 4.5 represents a major leap in our reasoning research, packing 355 billion carefully tuned parameters into a highly efficient mixture‑of‑experts architecture. It excels at multi‑step logic, mathematical proofs, and complex code generation while keeping latency within interactive bounds. An enlarged 256 k‑token context window enables full document analysis, legal discovery, and multi‑hour meeting transcription without external chunking. Specialist sub‑networks handle science, finance, law, and creative writing, dynamically routed to maximize accuracy where it matters. Advanced alignment techniques minimize hallucinations and enforce policy compliance, making GLM 4.5 a reliable partner for demanding professional workflows.
