inductionheads · x · 2026-08-22

Based on tokenizer analysis, the stealth model Ox Alpha is suspected to be using the cl100kbase tokenizer. This rules out major labs like OpenAI, Google, Anthropic, and xAI, pointing instead to Microsoft's Phi/MAI lineage or IBM Granite. The model is likely Microsoft's unreleased "MAI-2". It is currently free to try, offering 1M context, multimodality, and zero data retention.
