The inference cost structure has changed. Reports indicate a 213:1 input-to-output token ratio in agent scenarios, with long context and multi-step tool calls as the main cost drivers. Agent products cannot copy the cost model of conversational calls; per-call pricing needs redoing.
The on-device surface is widening. On 23 September 2026 Qualcomm announced at its Snapdragon Summit that the Snapdragon X2 series expands to the Linux ecosystem, saying agentic AI PCs are accelerating. For AI applications, the hardware base for on-device agents is broadening. At the same time, in August 2026 Google set new memory-use limits for Android apps against a backdrop of AI data-center-driven hardware shortages; tightening platform memory constraints squeeze the space available to on-device AI features. Both directions exist at once, so on-device deployment needs tiering by device.
Healthcare AI compliance is taking shape. A UK commission published 44 recommendations on healthcare AI regulation on 22 September 2026, covering compliance and market-access frameworks. For healthcare AI applications this means clearer regulatory requirements before delivery, likely raising compliance cost and time-to-market; conversely, products that pass review gain an access barrier.
