Attribution record · R5 · final routine status
Only the historical OpenRouter preview attribution is confirmed
OpenRouter’s historical page says its former Union Alpha preview was revealed as Pareto by Unbiased. It does not map the former OpenCode Go alias to Pareto or map either former alias to a fixed Pareto version or configuration.
Confirmed
Former OpenRouter preview → Pareto by Unbiased. This is historical attribution. It is not proof that a retired alias is equivalent to a current paid Pareto route or snapshot. R5-S01
| Question | Answer at R5 cutoff | Evidence boundary |
|---|---|---|
| Was the former OpenRouter preview disclosed as Pareto? | Yes. | The historical OpenRouter page makes that attribution. R5-S01 |
| Was the former Go alias Pareto? | Unproven. | No inspected source names the alias and Pareto together. Its omission from current Go sources is not mapping evidence. R5-S05 |
| Was either former alias a fixed Pareto version? | Unproven. | No inspected version/configuration/date pin. Unbiased says composition may change. R5-S07 |
| Which models and weights make up Pareto? | Not published in inspected sources. | “Blended” does not identify components or proportions. |
Historical speculation
Do not use launch-era fingerprint theories as attribution. Prompt self-identification, tokenizer counts, output style, safety behavior, account geography, and timing did not establish a provider or fixed configuration.
| Historical lead | Record | Current treatment |
|---|---|---|
| GLM / Z.ai | Image-prompt self-ID and tokenizer discussion without reproducible traces. | Unconfirmed historical lead. S16 |
| Kimi, Mistral, OpenAI, Qwen | Name, timing, context, style, and safety speculation in public threads. | Historical discussion, not attribution evidence. S10 |
