## How it was revealed
|
| 53 |
+
- **16 Oct 2026:** Reflection's [Beam launch post](https://reflection.ai/blog/beam-is-available) credits a MissingNo demo to Beam, released that day as Beam 1.0 with open weights.
|
| 54 |
+
- **15 Oct 2026:** The preview Cat Jam matched the same 24 counts in our test; Reflection names it as a Beam preview too. [Cat Jam guide](https://stealthmodels.com/cat-jam/).
|
| 55 |
+
- **11 Oct 2026:** Our token-count test matched MISSINGNO. on all 24 phrases to the tokenizer family that Beam turned out to use, five days before Reflection named it. [Details on the model guide](https://stealthmodels.com/missingno/).
