Google AI Edge Gallery is an Android and iOS app that lets users run open-source language models — including the newly released Gemma 4 family — entirely on-device with no internet required. It's essentially a showcase and sandbox for on-device ML, letting developers and power users benchmark models on their own hardware and explore capabilities without any data leaving the device. Version 1.0.11 shipped on April 2, 2026, adding support for Gemma 4 and on-device function calling. The app includes Prompt Lab for parameter testing, AI Chat with visible reasoning traces, image recognition, audio transcription, translation, and a small experimental offline game called Tiny Garden that uses natural language as input. The project has 16.6k stars and is fully open-source. With AICore integration landing in Android, Gemma 4 can run via the OS-level model runtime — meaning future apps can share a single on-device model instance rather than each bundling their own. This is the infrastructure play underneath the gallery.

Mediator.ai
Game theory + LLMs to find fair agreements both parties will actually accept

Mediator.ai applies Nash bargaining theory — the mathematical framework for finding equilibrium agreements in cooperative games — combined with modern LLMs to systematize conflict resolution. Rather than acting as a chatbot that facilitates conversation, it treats negotiation as a computational problem: given two parties' stated preferences and constraints, find the agreement surface where both parties are better off than walking away. The system can surface solutions neither party had considered by exploring the full solution space rather than iterating on each party's opening positions. It launched as a Show HN post today and is framed around turning "fairness" from a contested judgment call into a solvable optimization problem backed by decades of cooperative game theory research. This sits at an unusual intersection: serious academic economics (Nash's bargaining solution has a Nobel Prize attached to it) applied to an LLM product. Most AI "negotiation" tools are just chatbots with extra prompting. Mediator.ai's game-theoretic foundation means outcomes have mathematical guarantees about their fairness properties — a meaningful differentiator for high-stakes disputes where trust in the process matters.
Reviewer scorecard
“The function calling demo on-device is the real headline here. If Gemma 4 can handle tool use locally, that's a viable path to offline agents on Android — which opens up use cases in low-connectivity environments that were impossible before. The AICore integration means you write to one API and the OS handles the model.”
“Most 'AI negotiation' tools are just chatbots with system prompts. Nash bargaining gives this a real theoretical foundation — the Pareto-optimal solutions it finds have mathematical properties that pure LLM approaches can't claim. The Show HN reception was warm, which suggests the concept resonates beyond academic circles.”
“On-device model performance is still heavily hardware-gated — Gemma 4 running well on a Pixel 9 Pro doesn't mean it runs acceptably on the median Android device. Google controls the showcase, so the benchmarks are cherry-picked for their best hardware. Until AICore reaches broad adoption, this is a preview for early adopters.”
“Nash bargaining assumes rational actors with well-defined utility functions — neither of which describes most real disputes. When someone is going through a divorce or a contentious business breakup, emotions and power dynamics matter more than Pareto optimality. The theory is sound; applying it to messy human conflicts is a much harder problem than the landing page suggests.”
“The combination of AICore (OS-level model runtime) and on-device function calling is the blueprint for AI that survives network failures, regulatory data-residency requirements, and cloud cost pressures. Google is betting that the edge is where AI matures — this gallery is the proof of concept.”
“Commercial mediation and arbitration is a $300B+ industry that runs almost entirely on expensive human experts with inconsistent results. If Mediator.ai can formalize even a fraction of routine commercial disputes — contract disagreements, partnership splits, SLA negotiations — the market opportunity is enormous. The Nash foundation means you can audit the reasoning.”
“Audio transcription and translation that works offline and doesn't store your recordings anywhere is genuinely appealing for journalists, field researchers, and creators in low-connectivity areas. The privacy story alone makes this worth installing.”
“For freelancers and creators navigating contract disputes with clients, having a tool that can propose mathematically fair solutions — rather than just validating your position — could actually help resolve conflicts faster. The game-theoretic framing makes it feel less adversarial than a lawyer's brief.”
