MiniCPM5-2B on iPhone: blogger tests a local iMessage agent with 6 tools across 8 scenarios
PatrickToulme · x · 2026-09-12
Patrick Toulme argues the compute shortage's solution is local AI on devices people already own — billions of iPhones of untapped compute. Citing OpenBMB's MiniCPM5-2B (2B params, #1 under 4B on Artificial Analysis's index, topping the Agentic Index 20 vs 9, per the Densing Law of capability density doubling every 3.5 months), he tested it as an iMessage agent: 6 tools, 8 real-world scenarios, 3 runs each — handling tasks like "remind me to send Jordan the invoice tomorrow at 9am" with nothing leaving the phone. He believes Fable-quality models will eventually run fully locally on iPhones.
