GLM-5.2 vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Z AI / GLM-5.2
proDescription
Z.ai's flagship coding model is designed for agents that stay on a single task for a long time. GLM-5.2 holds a very large context that Z.ai describes as lossless, so an entire codebase fits into a single reasoning session. Trained specifically for long-horizon coding agents. Text only, with no image input. Open weights under an MIT license, so it can be self-hosted.
OpenAI / GPT-5.4 Nano
proDescription
OpenAI's smallest and cheapest current-generation model, built for speed and volume. GPT-5.4 Nano excels at classification, data extraction, ranking, and coding sub-tasks, and works well as a fast sub-agent inside larger systems. It reads text and images, supports web search, and follows instructions reliably. Reasoning depth is shallow by design, traded for very low latency and cost at scale.

Z AI / GLM-5.2
proRepository-Scale Engineering
Z.ai trained it for months on long-horizon coding scenarios, including large-scale implementation and performance optimisation. Developers report stronger production standards and better client-side and mobile work, including on-device debugging.
Effort Set Per Task
Two thinking effort levels, high and max. Z.ai explicitly recommends max effort for coding work, trading throughput for depth on the tasks where getting it right matters most.
Lossless Full-Scale Context
Z.ai's framing is that the point is not having a large window but making one usable. It reports stable performance across the full window rather than degradation at the far end.
Large Outputs At Once
Produces very large single responses, enough to generate or refactor big files without breaking the job into chunks and reassembling the results by hand.
Automated Research And Audits
Z.ai lists automated research among the tasks it was trained for. It can read a whole project and return an architecture map, module responsibilities, API contracts, data flows, and technical debt.
Text Only Input
Text only. No image, audio, or video input. Screenshots, diagrams, mockups, and scanned pages are outside this model's reading range, which rules them out for visual work.
OpenAI / GPT-5.4 Nano
proCoding Sub-Agents
OpenAI positions it for coding sub-tasks and as a fast sub-agent in multi-model architectures. Built for small, well-scoped jobs run at high frequency rather than whole engineering problems.
Adjustable Reasoning Effort
Reasoning effort ranges from minimal to high. Even at higher effort, it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Inputs
A large context window, enough to classify or extract from big batches of text in a single pass. Ample for the high-volume work it is built for without splitting the input.
Extraction And Ranking
OpenAI names classification, data extraction, and ranking as its core uses. Built to process structured, repetitive text work quickly and cheaply rather than to write long-form content.
Web Search For Current Facts
Supports web search as a tool, so it can pull live information into an answer. Useful in background and real-time systems where the data needs to be current.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. Audio and video are not supported.
