Cerebras is interesting beyond its IPO because near-1,000-token-per-second inference changes the shape of the work: draft, check, repair, compare, and return before the human loses the thread.

The useful question is how much AI capability would still remain if the proprietary frontier disappeared tomorrow.

The common claim is that AI cannot replace your job. That may be true. But jobs are bundles of functions, and the better question is which functions are already moving closer to reliable AI handoff.

Loophole is not interesting because it solves ethics. It is interesting because it treats moral principles like something you can draft, attack, patch, and escalate until the real conflicts in your values finally surface.

Attio, Linear, and PostHog are converging on the same product bet: one fixed dashboard cannot serve every user or every intent, so the SaaS homepage is shifting toward an agentic entry point. Chat is the router. Generative UI is what comes next.

The next real step for agents is genuine multi-agent runtime across different harnesses: paired review loops, handoffs, shared threads, and open protocols such as A2A.

As of March 24, 2026, mobile AI coding is splitting around where the work runs: a phone steering your own machine, or a phone watching cloud agents work somewhere else.

Claude Code autonomy is not one trick. It starts with permission friction and context hygiene, then moves through subagents and loop hooks, and becomes genuinely useful when the system can measure whether the last iteration actually improved the work.

The newest memory systems do not make language models inherently stateful. They build recall, updates, and temporal reasoning around the model instead. Gemini Embedding 2 is the first mass-scale vector embedding that is multimodal.

The most useful way to understand AI progress isn't by tracking model names. It's by tracking the operating model: from chatbots that only talk to systems that can plan, act, coordinate, and increasingly sit across software.

AI can speed up individual tasks, but that does not automatically create more free time. From personal experience, the saved capacity gets filled by more complex tasks and higher expectations.

Open AI baseline tracker

Floor / Ceiling

A public tracker for the moving floor of open-weight AI against the proprietary frontier ceiling.

View project

This tracker compares two moving AI baselines: the proprietary ceiling and the open-weight floor.

The ceiling is the best frontier capability available through closed systems such as GPT-5.5 Pro or Claude Opus 4.7. The floor is the strongest open model you could still use if those proprietary systems disappeared tomorrow.

What the floor means

The floor is not the average open model. It is the strongest openly available fallback for a domain, such as coding, agentic work, or general reasoning.

That matters because the floor tells you what capability has become durable. Once the weights are public and the licence is permissive, the baseline is much harder to remove from the world.

Current snapshot

The first snapshot treats Kimi K2.6, GLM-5.1, DeepSeek V4 Pro, Xiaomi MiMo V2.5 Pro, and Ling-2.6-1T as the current open floor candidates, with GPT-5.5 Pro and Claude Opus 4.7 as the proprietary ceiling candidates.

The model selection is editorial, but the points and gaps now use Artificial Analysis as of 1 May 2026: Coding Index for coding, Agentic Index for agentic work, and Intelligence Index for general reasoning. When a side lists multiple models, the side score is the highest published AA score among those models. Ling-2.6-1T currently has an AA Intelligence Index reference in this tracker, so it is listed as an open-floor candidate without changing the coding or agentic gaps.

Why track it monthly

AI progress is easier to understand when the floor and ceiling are separated. Some months the ceiling jumps. Other months the floor catches up. The important long-run question is not whether one lab is briefly ahead, but how much capability remains available even without the frontier APIs.
