OpenCode is offering it free for a week with zero data retention on prompts. Early benchmark claims position it near 'Fable 5' quality at 'GPT-5.6 Terra' pricing, and usage numbers already show roughly 1.96 billion tokens processed on day zero, with OpenCode claiming 5 trillion tokens/day capacity. A 3D scene rendering test reportedly showed 3x fewer tokens used than a rival model called Ox Alpha. Identity speculation about who built it is spreading faster than verified benchmark results. ## Content A model called Union Alpha dropped on OpenRouter and OpenCode today, and nobody will say who built it. That's the whole bit: it's free for a week, it's anonymous, and the community is already trying to reverse-engineer its identity. The specs are legitimately interesting. 262K token context window, up to 131K tokens of output, multimodal (images + text), tool calling support, and a zero-retention policy on prompts. OpenCode is advertising 5 trillion tokens per day in capacity, which is not a small infrastructure bet for something with no named owner. Benchmark-watchers are placing it "close to Fable 5 level" at roughly GPT-5.6 Terra pricing - frontier-adjacent performance at a price point that undercuts the obvious comparisons. Day-zero traffic on OpenRouter is already sitting around 1.96 billion tokens, which suggests the free tier is doing exactly what it's supposed to do: get people hooked before anyone knows what they're actually using. The community response is split between genuine curiosity and mild existential dread. @thdxr ran it through OpenCode's subagent tool specifically to probe its identity - the model, per its design, refused to reveal itself. His takeaway: "idk how much longer stealth models can even be a thing." That's the real question here. When a model is good enough to generate serious traffic on day one, the anonymity stops being a fun mystery and starts being a due-diligence problem. The stealth model format is becoming a pattern: drop something capable, make it free, collect usage data before anyone can form a critical opinion. Union Alpha is built for agentic coding workflows, which means developers are already running it on real tasks without knowing whose infrastructure they're trusting or whose training pipeline their outputs might eventually feed. The zero-retention claim helps, but "trust us" from an anonymous source is a specific kind of ask. Somebody built this. The week-long free window is the clock. ## Questions this post answers ### What is the Union Alpha AI model on OpenRouter and OpenCode? Union Alpha is an anonymous 'stealth' AI model released with no named creator, built specifically for agentic coding workflows. It is multimodal (text and images), supports tool calling, handles 262K tokens of context with up to 131K tokens of output, and is offered free for a week on OpenCode with a zero-retention policy on prompts. _Developers weighing a new stealth model for agentic coding can track early reports like this on daily.dev._ ### How much usage has Union Alpha gotten since launch? OpenRouter showed roughly 1.96 billion tokens processed on day zero of Union Alpha's release, and OpenCode claims a capacity of 5 trillion tokens per day. In one 3D scene rendering test, Union Alpha reportedly used 3x fewer tokens than a competing model called Ox Alpha to complete the same task. _Anyone comparing token efficiency across coding models can follow real-world usage data via daily.dev._ ## Community take How the wider developer community reacted, aggregated from 5 discussions and 54 comments across x (as of 2026-09-17). **TL;DR:** Reactions center on curiosity about who built Union Alpha and genuine interest in its low token usage and long context, tempered by skepticism that an anonymous vendor's zero-retention promise can actually be trusted or enforced. **Sentiment:** 25% positive · 45% mixed · 30% skeptical **The case for** - Some see the low token usage as a real efficiency win, attributing it to the model 'thinking less' and just writing code directly. - Free access for a week is seen as enough time to meaningfully benchmark the model against named competitors. - The stealth-drop approach is viewed by some as a clever way to gather unbiased blind benchmarking data before a branded launch. **The pushback** - Multiple commenters argue a zero-retention claim from an unnamed party can't be enforced or verified, since there's no accountable jurisdiction behind it. - Some frame stealth releases cynically as a PR/ELO-farming playbook rather than a genuine trust-first offering. - Server errors, quota limits, and the model evading identification attempts frustrate people trying to actually test it. - Guesses about the model's origin (GLM, Qwen, Kimi, MiniMax, a US lab) remain unconfirmed and scattered, showing real uncertainty. **By community** - x (mixed): Interest in the model's efficiency and mystery is mixed with pointed skepticism about whether an anonymous party's data-retention promises can be trusted. **Hottest debate:** Whether a zero-data-retention claim from an anonymous, unaccountable vendor can be trusted at all, versus it being a moot point since the anonymity is only temporary. **Open questions** - Who actually built Union Alpha? - What accounts for the 3x reduction in token usage — architecture, tokenization, or just less 'thinking'? - What happens to data submitted during the anonymous week once the vendor's identity and terms are revealed? **Highlights** > @adityamahapatra @svpino The reveal comes after the week when the code was already sent. Knowing the name later does not tell you what got kept. > — [keepyourheadai on x · 1 comments](https://x.com/keepyourheadai/status/2100268835161162084) > @svpino honestly the mystery is doing more marketing than the 256k context is > — [Avery\_Coree on x · 1 points](https://x.com/Avery_Coree/status/2100236950842016032) > @svpino The "anonymous stealth model" playbook is just glorified crowd-sourced ELO farming. Labs drop unbranded weights to dodge benchmark contamination scrutiny and get free human evaluations before silently quantizing the production release. > — [deanevals on x](https://x.com/deanevals/status/2100236670230556711) > @svpino This is exactly the kind of mystery model worth stress testing. No known creator, free access, agentic coding focus, and 256K context. The benchmarks are going to be very interesting once people figure out what’s actually underneath it. > — [stas\_sorokin\_ on x](https://x.com/stas_sorokin_/status/2100256305399153035) > @thdxr It not serving reasoning traces is throwing me for a loop. Because all the Chinese labs serve reasoning traces. But what American lab would stealth release? > — [CalebKotz63219 on x · 7 points](https://x.com/CalebKotz63219/status/2100324414361399343) **Source threads** - [x](https://x.com/testingcatalog/status/2100272203535188239) · 1 points · 4 comments - [x](https://x.com/rohanpaul_ai/status/2100271241685033105) · 0 points · 5 comments - [x](https://x.com/svpino/status/2100236223508041855) · 0 points · 25 comments - [x](https://x.com/thdxr/status/2100323046913356225) · 0 points · 20 comments - [x](https://x.com/thdxr/status/2100240225159045169) · 0 points · 0 comments --- Tags: [#ai](https://daily.dev/tags/ai), [#ai-coding](https://daily.dev/tags/ai-coding), [#opencode](https://daily.dev/tags/opencode), [#openrouter](https://daily.dev/tags/openrouter) [View this post on daily.dev](https://daily.dev/posts/union-alpha-showed-up-anonymous-free-and-already-burning-through-2b-tokens-g3jfkzc1q) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Union Alpha showed up anonymous, free, and already burning through 2B tokens","url":"https://daily.dev/posts/union-alpha-showed-up-anonymous-free-and-already-burning-through-2b-tokens-g3jfkzc1q","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/union-alpha-showed-up-anonymous-free-and-already-burning-through-2b-tokens-g3jfkzc1q"},"datePublished":"2026-09-16T17:15:20.367Z","dateModified":"2026-09-17T06:41:52.097Z","description":"An unidentified 'stealth' AI model called Union Alpha appeared on OpenRouter and OpenCode with no named creator, multimodal support, tool calling, 262K token...","image":"https://pbs.twimg.com/media/HSWqb9JXYAAdZBC.jpg","thumbnailUrl":"https://pbs.twimg.com/media/HSWqb9JXYAAdZBC.jpg","isAccessibleForFree":true,"articleSection":"Trends","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Trends","logo":"https://media.daily.dev/image/upload/s--ZfSp3asX--/f_auto,q_auto/v1780996004/logos/trends?_a=BAMAMiWQ0","url":"https://daily.dev/sources/trends"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/union-alpha-showed-up-anonymous-free-and-already-burning-through-2b-tokens-g3jfkzc1q","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai,ai-coding,opencode,openrouter","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Trends","item":"https://daily.dev/sources/trends"},{"@type":"ListItem","position":3,"name":"Union Alpha showed up anonymous, free, and already burning through 2B tokens"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/union-alpha-showed-up-anonymous-free-and-already-burning-through-2b-tokens-g3jfkzc1q#faq","mainEntity":[{"@type":"Question","name":"What is the Union Alpha AI model on OpenRouter and OpenCode?","acceptedAnswer":{"@type":"Answer","text":"Union Alpha is an anonymous 'stealth' AI model released with no named creator, built specifically for agentic coding workflows.
