Union Alpha launch evidence audit

Research cutoff 2026-09-16T21:03:17Z UTC. This report preserves launch-day uncertainty; source evidence is summarized and linked rather than reproduced.

Finding

Union Alpha was listed on OpenRouter as stealth/union-alpha: $0 input/output, text/image input and text output, 262,144 context, 131,072 maximum output, and declared tool-related features. OpenRouter says the provider is anonymous and may retain prompts/completions, though not for training. S01

Probe disposition

Three tiny OpenRouter requests and one OpenCode Go request were attempted with pre-existing environment credentials at 2026-09-16T21:03:35Z. Each ended with DNS EAI_AGAIN before HTTP/TLS. This is environment-blocked, not a model failure, availability outcome, rate-limit observation or successful access test.

Rate-limit conclusion

No Union-Alpha-specific OpenRouter request, token, concurrency or daily quota was located. OpenCode Go’s “Unlimited” estimates are a limited-time route-specific listing and do not transfer to OpenRouter. Generic OpenRouter free-plan/free-model rules must not be applied to this slug. S02 · S06

Benchmark and identity conclusion

No qualifying public structured benchmark was located; claimed DeepSWE and Terminal-Bench values lack a sufficient method package and are not scored or graphed. No owner/lab attribution was confirmed. GLM, Kimi, Mistral, OpenAI and Qwen theories remain low/very-low-confidence leads. S09 · S10
