psql_bm25s: when retrieval stops being a budget item

13 May 2026

A Postgres-native lexical retrieval primitive for long-running, multi-agent work. Read technical report here. TL;DR 01 Long-running agents lose to retrieval, not context. The longer they run, the more their usefulness depends on cheaply re-reading the state they have already accumulated. 02 Most production agent state already lives in Postgres. Existing Postgres BM25 extensions work, but are slow enough that harnesses end up rationing retrieval, calling it occasionally ins

From RALPH to Zenith: Designing harnesses for long-running agents

Read the technical report on GitHub. TL;DR 01 Long-running agents often fail not because they cannot make progress, but because they stop before the task is truly complete. 02 We tested five harness designs across eight long-horizon tasks to isolate the control mechanisms that matter: repeated gap-finding, revisable planning, independent verification, adaptive orchestration, and stopping discipline. 03 RALPH is the strongest simple baseline because it forces each

Introducing Factory

Describe your idea in a single sentence. Get a full production on an infinite canvas: images, video, voice, music, and every scene wired up for you. Every creator knows the feeling. You have an idea for a short film, a campaign, a storybook, or just something that lives vividly in your head, and then you sit down to make it and you're suddenly juggling five browser tabs, three apps, and a pile of folders named "final_v7_REALLY_final." The tool gets in the way of the thing. We built Factory to

The Cosmological Constant Is Positive

The full paper can be found here, along with the microsite. Einstein called relativity a theory of principle, one where the principle itself constrains the physics, the way the axiom determines the mathematics. In 1917, he broke his own rule. He added a term to his field equations by hand, the cosmological constant Λ, because he needed the universe to sit still. A static universe that didn't collapse under its own gravity required something pushing back, and Λ was the push. He didn't need to

One Postulate

Useful links: * Paper * NotebookLM * One Postulate Website Two Postulates In 1905, Einstein built special relativity on two postulates. The first was a principle. The laws of physics look the same in every laboratory moving at constant velocity. No experiment you can perform inside a sealed, gliding room will tell you how fast you are moving. The second was an observation about light. Light travels at the same speed in every such frame, no matter who measures it. The first is a claim ab

Introducing Logos

A First-Principles Augmented Intelligence System We are happy to announce Logos, a first-principles augmented intelligence system. Logos is in early development, but the results so far have been insightful across domains. Over the next few weeks we will be sharing a series of results of increasing importance in physics as the first domain. Today's is a lovely one that has been sitting quietly in special relativity for 121 years. AGI The dominant picture of where AI is going is one of autono

On First Principles: Remembering Albert Einstein

"The important thing is not to stop questioning," Einstein once said. "Curiosity has its own reason for existence." Seventy-one years ago today, Albert Einstein died in Princeton. He was still questioning. Pages of equations sat at his bedside. His genius was reasoning from first principles. A refusal to take the foundations on faith. A willingness to question inherited pictures of the world, and to begin again from the ground up when the old picture no longer fit. He rebuilt physics from a p

Common Ground Core: From Agent Chaos to Structured Intelligence

The past year has seen an explosion of “agent frameworks.” Demos look impressive. Loops run. Tasks complete. But as soon as you try to scale beyond a single agent in isolation, things start to break in familiar ways: * Context gets lost * Deadlocks appear * Agents hallucinate into vacuums * Coordination collapses under real-world complexity Most agent stacks ship without a nervous system. They can act, but they cannot reliably coordinate. Unstructured intelligence is just entropy. We buil

II-Agent V1 is Here

The open-source AI agent built for real work, now out of Beta. Introduction Today we're releasing II-Agent V1, the first production-ready version of our open-source intelligent assistant. It delivers state-of-the-art performance, scoring 61.8% on Terminal Bench and 45.1% on SWE Bench Pro. For months, thousands of builders used II-Agent in beta to ship apps, run research, and automate the work that used to take hours. They found bugs. They pushed limits. They told us what was missing. V1 is th

II-Agent Chat

Any Model, All in One Place II-Agent Chat is now live. It’s a feature within II-Agent that lets you work across multiple models and tools in one place. The web-hosted version comes with Gemini 3, Sonnet 4.5, and GPT-5 ready to use out of the box. You can connect your own API keys, switch models within a single thread, and use them alongside Claude Skills, GPT-5 Code Interpreter, and text file search. II-Agent, the system powering Chat, is now state-of-the-art on Terminal Bench 2, the definiti

II-Agent Beta Now Open

Today we’re opening II-Agent to everyone. Earlier this month, we rolled out the private beta with Bring Your Own Key (BYOK), Codex integration, editable slides, and full-stack web builds. Today at FII Institute's FII9, our founder Emad Mostaque, alongside FII Board member Peter Diamandis, announced SAGE, the Sovereign AI Governance Engine for policy in the intelligence age. Now, you can access part of our Sovereign AI stack and start building toward that vision at agent.ii.inc. What’s new

Hosted II-Commons Beta

Featured update: December 18th, 2025 Hosted II-Commons Beta is Now Live Building on the datasets and APIs announced below, we are excited to launch the hosted II-Commons Beta. Powered by the latest Gemini 3 model, this new interactive interface transforms our backend capabilities into a seamless workspace for scientific exploration. Key updates include: * Unified Research Agent: Query arXiv and PubMed simultaneously in a single conversation, eliminating the need to switch contexts. * In-D

II-Agent Update: Beta Web App, BYOK, Editable Slides, Codex

Introduction II-Agent updates and hosted web app beta are now live. These updates take the original II-Agent prototype you’ve seen and refines it into a fast, reliable product for everyday use. Waitlisted users can now try the web app on agent.ii.inc. Not on the waitlist? You can self-host the new II-Agent today, see public repo. Why a Web App, and Why Now The initial II-Agent release proved that agentic workflows can dramatically accelerate technical work, but our community told us they n

The Last Economy

Today we are releasing The Last Economy, the first book of Intelligent Economics, a unified theory of economics for the Intelligence Age. Your economic life expectancy is shrinking. Not your job. Not your career. Your relevance as a human being in the economy itself. For 300,000 years, intelligence was scarce. Humans monopolised thinking. Education created value. Cognitive labour commanded a premium. That age is ending. In the next thousand days or so, intelligence becomes abundant. Machines

II-Search

Introduction The II-Researcher framework is dedicated to producing powerful, open-source agents for complex research. Our latest additions to this initiative are II-Search-4B and II-Search-CIR-4B, two 4-billion-parameter language models designed to tackle complex information-seeking and open-ended research tasks. II-Search-4B introduces a three-phase SFT and one-phase RL curriculum that progressively stimulates tool use, refines multi-step reasoning, and applies rejection-sampling fine-tuning
