GLM-5.2 vs Kimi K3 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.
Kimi / Kimi K3
proDescription
Kimi K3 is Moonshot AI's newest and most capable model, released in July 2026. At 2.8 trillion parameters, it's the largest open model anyone has shipped so far, and it can hold about a million tokens in memory at once. That's enough room for an entire codebase or a full stack of long documents in a single chat. It comes in two versions: K3 Max for everyday chat and coding, and K3 Swarm Max, which splits one big job across many copies of the model working in parallel.
Where K3 really earns its keep is coding. It's good at finding its way around large projects, making changes that touch many files, and fixing bugs by reading your actual test results and error logs instead of guessing. You can also share screenshots, diagrams, and error messages as images, and it will answer based on what's actually on the screen.
In early testing, K3 beats Claude Opus 4.8 and GPT-5.5 on several coding tests while costing far less to run. It still sits a step below Claude Fable 5 and GPT-5.6 Sol overall, so for the very hardest questions you may get a better answer from one of those. On Aymo, switching between them takes one click.

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.
Kimi / Kimi K3
proBuilt for Real Coding Work
It handles changes across many files, sticks with a task through hundreds of steps, and fixes bugs by reading your test output and logs.
Big jobs, split up for you
Give it something too large for one pass, like reviewing a folder of contracts, and it breaks the work into pieces and handles them side by side.
Longer Context Window
1M token window for full codebases, contracts, and research corpora
Parallel Research Tasks
Run several research threads at once through coordinated sub-agents, useful for broad, exploratory investigation.
Web Search Tool
Moonshot provides web search as an official tool in the Kimi API, so the model can ground answers in live sources rather than working only from what it learned in training.
Native Image Support
Share a screenshot, a diagram, or an error message and get an answer based on what's actually in the image.
