Good morning. Here is your AI briefing for Saturday, 24 October 2026. 12 stories today. Securing our frontier model training environment. OpenAI explains how we strengthened containment for frontier model training and evaluation, including offline environments and high-compute red-teaming. Introducing Kimi K3.1 Pro. (via) Kimi K3.1 Pro landed on the Kimi API today - it's not yet open weights, but Moonshot promise "Full model weights will be released by Nov 4, 2026". LitPivot: Developing research ideas through dynamic contextualization within the literature landscape. Encountering a new paper can change a research idea's trajectory. Rapidly scaling online storage to serve over 1 billion ChatGPT users (Part II). Learn how OpenAI scaled Habitat with reliable multi-tenancy, global caching, and Azure Cosmos DB to deliver 12× faster reads for ChatGPT. Quick Study.

Introducing Kimi K3.1 Pro

New Models

(via) Kimi K3.1 Pro landed on the Kimi API today - it's not yet open weights, but Moonshot promise "Full model weights will be released by Nov 4, 2026".

  • $2.00/million tokens
  • GPT-6.1
  • GPT-6
  • Gemini 4
  • They're also offering a "Highspeed" version that's 2-3x faster, at twice the price (except for input token cache hits, which are priced the same).
  • The US dollar pricing is $2.00/million tokens for input and $10/million for output - the same as GPT-6.1 Sol and half the price of Claude Opus 5.5.
  • Moonshot's own benchmarks show Kimi as approximately level with Opus 5.5 and GPT-6 Astra - beating them on a few benchmarks, coming close on others.

LitPivot: Developing research ideas through dynamic contextualization within the literature landscape

New Models

Encountering a new paper can change a research idea's trajectory.

  • We call this process a literature-initiated pivot: a change in research direction prompted by reading prior work.
  • With collaborators at the University of Pennsylvania, we developed LitPivot, a system that helps researchers navigate these pivots.
  • In a study with 17 researchers, domain experts rated research ideas developed with LitPivot as better grounded in the literature than those developed…

Jack Dorsey’s Block made an AI model that talks to you like an awkward new friend

Jack Dorsey’s Block announced an AI model called Dessa that’s trained “from scratch on nothing but human conversation,” and to show off the model, Block shared chats it has had with humans that can occasionally be a little…

  • Take this one, for example, shared by Dessa lead Ragavan Thurairatnam.
  • The Dessa website features a few other examples, like a back-and-forth about Christopher Nolan’s films (including Dessa going on an unexpected…
  • On the website, the Dessa team says that Dessa is a “true speech-to-speech model, and everything it knows came from human speech,” and it can run…

[AINews] Kimi 3.1 Pro 104BA-2.8T: Fable-5.1-Class Open Weights narrows Closed-AI lead to 1 month... and Pro Highspeed API with 2-3× speed

2 months ago we covered Z.ai CEO Prof Jie Tang’s prediction that we’d get a Fable-class open weights model by year end.

  • GPT-6
  • You can tell Kimi is proud of their latest model by how fancy their landing page is:
  • As usual we don’t get much research detail - the update is somewhat similar to Z.ai’s 5.2-5.3 bump - a minor version bump for a lot more…
  • Kimi K3.1 Pro is a post-trained version of Kimi K3, with substantially larger post-training compute.

GitHub Changelog

Usage metrics API adds usage from tools like OpenCode

The Copilot usage metrics API now reports model usage from more of the tools your developers use with Copilot, including tools like OpenCode that weren’t previously captured in your reports.

  • client: The tool that sent the requests, such as opencode, claude_code, codex, zed, copilot_cli, github_app, cloud_agent, code_review, vscode, or…
  • totals_by_model: The same request and token metrics broken down by model, with a model_selection_mode that shows whether the model was requested…
  • More developers now use Copilot as the model provider behind tools outside the IDE.

Anthropic Python SDK releases

Anthropic Python SDK v2.3.0 released

OpenAI says it will no longer train its AI models on the live internet, citing “significant risks”

On Friday, OpenAI said that it will train its models using cached copies and simulated versions of the internet instead of the live web because the models are too unpredictable to be trusted with live internet access.

  • The frontier lab announced its new policy two weeks after its rival, Anthropic, began limiting its newest and, in theory, most capable models from…
  • “Based on the current state of alignment research, monitoring systems, and the security of internet infrastructure, we believe the responsible…
  • OpenAI said that as recently as September 20, one of its frontier models exploited a misconfiguration to access the internet.
