Codex Day 1: GPT-6 Astra and GPT-6.1 Sol run about 50% faster on subscriptions, partners included

The first drop of OpenAI's 28-day improvement-or-reset run is an inference speedup of roughly 50% for GPT-6 Astra and GPT-6.1 Sol when used through a ChatGPT subscription, including partner tools that use Sign in with ChatGPT like OpenCode, Pi, Amp, and Devin, with nothing to change on your end. API speeds aren't part of it, and one early forum benchmark saw 6.1 Sol get slower mid-rollout, so check your own runs.

Superagent open-sources Security-One 27B, a model that scores agent tool calls and inputs as safe or unsafe

Instead of writing out an answer, the Apache 2.0 model returns probabilities for answers you define (like safe and unsafe ) for a prompt, tool call, code change, or alert, so your own code picks a threshold to allow, block, or escalate; Superagent reports catching 599 of 600 BIPIA prompt injections. Prompt injection screening is the best tested use so far, it flagged 12% of tricky benign NotInject inputs, and the numbers are Superagent's own, so tune it on your own traffic and keep real permission checks outside the model…
