I used GPT-5.6 Sol Ultra in Codex to investigate OpenCode’s stealth “Ox Alpha.” Two clues point to z.ai/GLM-5.3: exact chat.z.ai 1210/1214 API errors, plus 17 multilingual/code/emoji prompts tokenized exactly like GLM-5. MiMo didn’t match.
@Veeeetzzzz · 21 ago 2026 · Tesis GLM
Ox Alpha has a 97% cache hit rate when I use it with @pidotdev. It’s definitely a GLM family model. I’ve only seen one inference provider have a 90%+ cache hit rate and that’s chat.z.ai. Anthropic avg is 64% and OpenAI is 83%.
@h1kaman · 21 ago 2026 · Tesis GLM
Evidence strongly suggests Ox Alpha IS an unreleased Zhipu GLM. Zhipu live-tested GLM-5 as Pony Alpha before. Tokenizer math, video pipelines, and character-for-character responses match GLM architecture. Kingbench: 87.5% vs GLM-5.3’s 91.25%.
@h1kaman · 21 ago 2026 · Bench
OpenCode is giving away a stealth model called Ox Alpha this week — 1M context, text/image/video input, 100T tokens/day capacity. I tested it against GLM-5.3 trying to find one task only GLM could solve. Couldn’t find one.
@h1kaman · 21 ago 2026 · Bench
Ran 5 more tasks (logic, code bug-hunt, math, strict instruction-following, domain knowledge). Correctness 5:5. Latency: GLM 8.9s avg, Ox Alpha 12.6s. Worst gap on coding: 6.7 vs 18.3 seconds.
@rustyblnk · 21 ago 2026 · Tesis GLM
did you just skip the fact that zhipu literally just built a 1GW data center and are offering insane limits specifically to stress-test huawei chips under heavy load? ox alpha is glm flash/air
@uzairansar · 21 ago 2026 · Duda
Ox Alpha should scare the big labs. First of all, how do they have so many tokens to give away for free? A new GLM? Maybe Xiaomi? It’s def frontier.
@DylanJFetch · 21 ago 2026 · Tesis MiMo
GLM 5.2 and 5.3’s performance were nearly identical on OpenTTD-Bench, so I don’t think the rumors that Ox Alpha is GLM 5.4 are true. I suspect that it is Xiaomi MiMo-V3.
@DylanJFetch · 21 ago 2026 · Contra
I’m not seeing what others are seeing from Ox Alpha. 17% of requests timed out. Took 10x as long as most other models.
@krunofm · 21 ago 2026 · Duda
crazy theory but what if Ox Alpha is Anomaly’s model, maybe a finetune of GLM? they probably gathered plenty of valuable data from the other free models…

@D4RW1NEXE · 21 ago 2026 · Tesis MiMo
Frontier labs do not give away 100T tokens daily by accident. Ox Alpha claims origins from An Undisclosed Organization via @elder_plinius, yet outclasses Opus on key tests. 1M context and OpenCode telemetry leave one plausible backer: Xiaomi stress testing MiMo.
@elder_plinius · 21 ago 2026 · Tesis GLM
Ox-alpha is from Zai, GLM-5.X family my agent has spoken.
@davis7 · 21 ago 2026 · Tesis GLM
99% sure it's GLM-5.x, all the evidence points to it (same video encoder, same tokenizer, style matches, same audio rejection, etc.)

Ok I tried the mystery model Ox Alpha and built a Medicare explorer app… similar to GLM and definitely not a deepseek … 121K tokens

Ox Alpha is the 5th anonymous stealth model on OpenRouter (following previous models later confirmed by Zhipu AI, Xiaomi, Ant Group, and Meituan). Empirical output formatting and table-sorting tests strongly suggest Ox Alpha belongs to Zhipu AI's GLM model family.

A mysterious new AI model just appeared. Ox Alpha offers a 1M context window, multimodal capabilities, zero data retention, and nearly unlimited usage for an entire week. Nobody knows which company built it.
@filicroval · 21 ago 2026 · Tesis GLM
from what i've tested, Ox Alpha strongly points to a GLM-5.3 multimodal variant: both Ox Alpha and GLM-5.3 share the same tokenizer.
@MaxForAI · 20 ago 2026 · Tesis GLM
Ox Alpha 的原始Token 数和GLM-5.3 几乎一模一样，每次只固定多出75 个Token。换句话说，它的底层Tokenizer 指纹和GLM-5.3 高度重合。更巧的是，Ox Alpha 还支持图片输入。
@r/singularity · 21 ago 2026 · Tesis GLM
I fingerprinted Ox Alpha: same tokenizer as GLM-5.3 (+75 token offset), z.ai's exact error strings, near-identical temp-0 outputs. Kimi/Qwen/MiMo/MiniMax all diverge.
@JoshRadDev · 21 ago 2026 · Tesis GLM
For anyone who thinks that Ox Alpha is an American model, I got Chinese error logs when passing invalid params. I think @synthwavedd and @kimmonismus are right that this is GLM 5.3 Flash. Also, it has strings that match other GLM errors from ModelScope.
@Adidotdev · 21 ago 2026 · Tesis GLM
Ox Alpha isn’t just a mystery model anymore — it’s a pattern. 5th anonymous stealth in 6 months. Last 4? All Chinese labs. Tokenizer +75 vs GLM-5.3. Video encoder = GLM-5V-Turbo. Ben Davis 99%. Free period ends around Aug 27.

The only thing that makes sense and checks all the boxes for the clues we have for Ox alpha is Composer 3. The timing, the fine tuned GLM base, the amount of compute behind it… has to be it.
@j_frkw · 21 ago 2026 · Duda
Ox AlphaはComposer 3説。そうだったらSuperGrok Heavyがかなり魅力的になる
@eberdoganbulut · 21 ago 2026 · Tesis GLM
one of the points of debate around Ox Alpha is whether Zai / GLM actually has this much compute or not. did everyone miss the news last month about them acquiring a 1GW data center?
@LeroyLi311063 · 21 ago 2026 · Contra
So many routers offering Ox Alpha for free is ridiculous; it doesn't seem like something chat.z.ai could provide. To be fair, Ox Alpha isn't better than GLM-5.3; it's more like a post-trained version of GLM-5.2.
@luongnv89 · 21 ago 2026 · Duda
Ox Alpha is a really good model. Many people said that it is an GLM model (with proof). I think it could be Grok 4.7 — generous free usage (who can have this kind of compute power).
@piersonrdavis_ · 21 ago 2026 · Bench
@OpenRouter Ox Alpha on an internal skill for abstraction. 6k+ lines, read only bug hunt, 23m. 2 real gaps, 0 severity-1 findings. 7.5/10 - possibly GLM family

ox-alpha has that big model smell. I’m getting around 63% at 47K avg output tokens on a DeepSWE subset. Pareto optimal amongst open models and just shy of Grok 4.6.

Fingerprint result: OpenRouter’s Ox Alpha strongly points to a hidden multimodal GLM-5.3 variant. Across 25 diverse prompts, native token counts matched GLM-5.3 exactly apart from a constant +75-token hidden wrapper. Ox also accepts image input. Identity is unconfirmed.

I stopped asking the model who it was and started probing the API. Illegal max_tokens → error 1210. Empty input → 1214. Same Z.ai codes, same Chinese punctuation. Four tokenizer probes: OX 88/106/97/108 vs GLM-5.3 13/31/22/33. Δ = +75 every time. Public GLM-5.3 is text-only; OX takes images and video.
@BohuTANG · 21 ago 2026 · Tesis GLM
Tokenizer: ox vs glm delta is constantly 75; MiMo is different. CoT: both think in English on Chinese questions with the same opener. BIP39 word pools overlap (harbor/velvet). Conclusion: unpublished multimodal GLM-5.3 variant.

Hard evidence, independently reproduced (own test videos, own prompt_tokens): ox and GLM-5V-Turbo match token-for-token 296/296/884/1064. Swap the clip content, still 296.

Summary why Ox Alpha is a GLM model: dozens of prompts, token counts match glm-5.3 with a fixed +75 offset; invalid reasoning settings return chat.z.ai error 1210; thinking cannot be disabled (low/high/max); video tokens match glm-5v across duration, fps and resolution.
@evverin · 21 ago 2026 · Tesis GLM
Ox Alpha is likely a GLM model. Same 1M context and 131K output as GLM-5.3. Identical mandatory low/high/max reasoning. Same API defaults. Exact 75 token offset across six multilingual tokenizer tests.
@vineeth_agi · 21 ago 2026 · Tesis GLM
Someone fingerprinted Ox Alpha using OpenRouter + OpenCode. Tokenizer matches GLM-5.3 exactly (+75) across English, German, Chinese, code & emoji. Same invalid reasoning_effort error. Near-identical temp-0 outputs.

Anonymous model landed between MiniMax M3 and GLM 5.3 in our 32-task sales benchmark. MiniMax 91.75, Ox Alpha 89.24, GLM 5.3 87.02. OpenRouter charged $0 for all 140 Ox calls.
