Two Deals in Two Days Put a Model Inside Tencent and Alipay
WorkBuddy took Step 5 Preview on 12 October, and Alipay’s agent flow opened a day later through the STEPX Neo handset.
StepFun signed two platform deals within 48 hours in mid-October 2026: Tencent’s AI workspace WorkBuddy adopted its flagship Step 5 Preview on 12 October with a two-week exclusive free period, and on 13 October the company’s STEPX Neo handset wired its Amoo agent into Alipay’s Abao to complete recommendation, ordering, payment and redemption inside one conversation. Step 5 Preview is a sparse MoE model with 600 billion total parameters and about 27 billion active per token. Alipay said its agent had completed over 10,000 service integrations, with agent purchase tasks up sevenfold in five months. The commercial read is that model vendors are converting from API resellers into traffic distributors paid on transaction flow.
