The license — not the benchmark — decides whether you can ship a coding agent on GLM-5.2, Kimi K2.7, or MiniMax M3, and whether you own the tokens it generates. Line up the three open-weight coding models everyone is arguing about — **GLM-5.2**, **Kimi K2.7 Code**, **MiniMax M3** — and the conversation is always the same benchmark row: SWE-bench Pro, Terminal-Bench, who beat whom by how many points. It's the wrong column to sort on. The column that decides whether any of them ends up inside your product is the one nobody screenshots: the license. And on that axis the three models are not close. They sit on three genuinely different tiers, and the tier is what survives contact with a paying customer. "Open weight" is doing an enormous amount of quiet work in those release posts. It means you can download the parameters and run them. It does *not*, by itself, mean you can put the model behind a paywall, redistribute a fine-tune, or — the one that matters most for an agent — train your own model on what it produces. Those rights come from the *license*, and the license text is where these three releases diverge hard. Tier one: plain MIT and Apache — ship anything GLM-5.2 is the easy case. Z.ai released the weights under the **MIT License**: no revenue clause, no monthly-active-user ceiling, no field-of-use restriction. You can serve it inside a paid coding agent, fork it, fine-tune it, and redistribute the result under whatever terms you like. It sits in the same permissive bucket as DeepSeek's MIT-licensed weights and Qwen3's Apache 2.0 — the tier where the license simply gets out of your way. As I noted when [GLM-5.2 matched the closed models on agentic coding](/posts/glm-5-2-open-weight-agentic-coding), the permissive license is half of why the price story is real: you can actually deploy the thing without a lawyer in the room. The underappreciated MIT right is **distillation**. MIT explicitly permits using the model's outputs to train another model — which is exactly why a generation of smaller reasoning models were bootstrapped on DeepSeek-R1 traces. Hold that thought; for a coding agent it's the whole game. Tier two: Modified MIT — permissive with a tripwire for giants Moonshot ships the Kimi line, including [K2.7 Code](/posts/kimi-k2-7-code-token-efficiency-agentic-coding), under a **Modified MIT License**. Read the diff against stock MIT and there is exactly one added clause: if your product or service crosses **100 million monthly active users** *or* **$20 million in monthly revenue**, you must prominently display "Kimi K2" in the user interface. Below that, it behaves like plain MIT — commercial use, fine-tuning, and distillation all allowed. > A license clause aimed at hyperscalers is, for everyone else, a compliment you'll never have to pay. The clause is a piece of positioning, not a restriction: it lets Moonshot keep the model free for the entire startup and mid-market while stopping a trillion-dollar platform from white-labeling it with no attribution. For your coding agent, treat Modified MIT as permissive and move on — the tripwire sits at a scale where you'd happily add a logo. Tier three: community licenses — where the fine print lives MiniMax M3 is the one to read slowly. It ships under the **MiniMax Community License**, and that is *not* an open-source license. Non-commercial use is free; commercial use for a company under $20M in annual revenue is free *only if* you email MiniMax and add a "Build with MiniMax" label; larger companies negotiate a separate agreement. None of that is unreasonable — but none of it is MIT, and the difference is a contract you now have obligations under. It's the pattern I flagged in [M3's launch](/posts/minimax-m3-open-weight-1m-context): the architecture is the most trustworthy thing in the release and the license is the part you have to actually diligence. There's a tell in M3's own history that matters more than any single clause: MiniMax **revised the license after launch**, loosening the commercial terms in response to community pushback. Good outcome — but sit with the mechanism. A custom community license is a document the vendor controls and can rewrite. An MIT or Apache grant on the version you downloaded is irrevocable; a community license is a moving dependency. Building a product on one means your legal footing can shift under you between releases, and the benchmark table will never warn you. The canonical version of this tier is Meta's **Llama Community License**, worth knowing as the reference point: a 700-million-MAU threshold above which your grant auto-expires, a ban on relicensing derivatives under any other terms, and — the sharp edge — a prohibition on using Llama outputs to train any non-Llama model. The clause that actually bites a coding agent Here is the non-obvious part, and it's specific to what a coding agent *is*. An agent is a data-generation machine. It emits millions of tokens of code, tool traces, diffs, and pass/fail signal — which is nearly ideal training data. The moment you consider fine-tuning a smaller model on your agent's transcripts, or building an eval set from them, or distilling a cheaper in-house model, the governing question becomes: *what does the license of the model that generated those tokens permit?* On MIT weights (GLM-5.2, DeepSeek) and Modified MIT (Kimi), the answer is: distill freely, the exhaust is yours. Under Llama's license it's a flat no. Under a custom community license it's ambiguous — and ambiguity you can't resolve is a liability you carry. So the MAU cap is a red herring for almost everyone; the real fork is whether the model's license lets you *own the byproduct of running it*. That's the term that changes what you can build next, and it's invisible on the leaderboard. Sort your shortlist by benchmark to decide which model is *good enough*. Then re-sort by license to decide which one you can actually ship — and, if you're planning to learn anything from its output, which one lets you keep what it makes. On today's board that puts GLM-5.2 and Kimi K2.7 in the "ship it" column, and MiniMax M3 in the "read the contract, and re-read it next release" column — regardless of who's winning SWE-bench this week.
