OpenAI says API and credit pricing for GPT-5.6 Sol will fall by more than 20% for the next three months. The temporary cut gives teams a defined window for comparing production costs.

Gemini 3.7 Flash pairs low ARC-AGI cost with rapid adoption

Sundar Pichai

Sundar Pichai calls Gemini 3.7 Flash Google's fastest-growing model and says it now runs in Search and the Gemini app. The ARC Prize results he cites report 84.6% on ARC-AGI-2 at $0.25 per task. They also report 95.5% on ARC-AGI-1 at $0.12 per task.

A plausible recommendation contradicted the postmortem

AI Engineer

An agent investigating QA latency recommended re-enabling asynchronous dispatch because it couldn't see the Slack discussion and postmortem that disabled the feature after an outage. With a task-specific summary of those sources, it produced a recommendation consistent with the prior decision.

The MCP roadmap adds events, discovery, and agent communication

David Soria Parra

David Soria Parra describes the open-source roadmap as directional. The listed work includes agent-to-agent communication, triggers and events, progressive discovery primitives, and proof-of-possession support.

What 100 large repositories tell coding agents

r/AI_Agents

A survey of the 100 largest GitHub repositories examines what maintainers put in their agent instruction files. It focuses on governance, testing, and repository-specific working rules.

OzBrain proposes shared knowledge for teams and agents

Show HN

OzBrain presents a shared knowledge and memory system for agents and their human teams. It addresses the same operational gap as the Linear example: relevant decisions are scattered across systems the agent may not understand together.

Qwen3-TTS reaches 34 milliseconds to first audio

Nari Labs

Nari Labs reports 34 milliseconds to first audio and throughput of 10 requests per second for its open-source Qwen3-TTS implementation. Those figures target speech systems that need to answer inside an interactive loop.

A 250 million parameter model fits in 60 MB

r/MachineLearning

The author describes a quantized model trained on 30 billion tokens that deploys in 60 MB. The project tests how much language-model behavior can fit into a CPU-oriented package.

A self-hosted software factory combines agents and sandboxes

Jake Saunders

Jake Saunders documents an almost fully self-hosted software factory built around sandboxed agents. The write-up covers the execution layer for teams that want to run the system on infrastructure they control.

AgentSight adds kernel-level tracing with no code changes

Show HN

AgentSight uses kernel-level instrumentation to observe agent activity without modifying application code. It covers the tracing layer for self-hosted deployments where model calls, tools, and processes need a common operational view.

Pennsylvania asks residents to report data-center projects

Governor Josh Shapiro

Governor Josh Shapiro announced new requirements for AI data centers and a state channel for residents to report projects. A project-by-project complaint registry gives local siting disputes a direct route into state review.

David Sacks contests Pennsylvania's data-center rules

David Sacks

David Sacks argues against Pennsylvania's intervention in data-center development. Read it alongside the governor's announcement for the federal-policy response to the state's siting mechanism.

Orbital compute attracts a $250 million round

Philip Johnston

Philip Johnston reports a $250 million funding round at a $2.3 billion valuation for orbital AI compute. The financing puts an off-planet alternative beside the same day's disputes over where to build capacity on the ground.
