OpenAI's API pricing page drops ten older models, including o1, o1-pro and GPT-4
Ten older models disappeared from OpenAI's API pricing page on November 2, 2026. This is the pricing page itself, not an OpenAI announcement, and removal from a pricing page is not by itself a retirement notice. The page's entries give prices without a unit.OpenCode is rebuilt to run inside browser devtools
Adam (adamdotdev) said on X on November 2 that he rebuilt OpenCode to run inside a browser's devtools console, using console.log statements for its interface. It is built on a framework he links at textjs.org, and he invites developers and their agents to build other console apps with it. A note with the post says a VS Code extension is in the works and a Chrome devtools extension is still to come.
Anthropic releases FlashProve, an open-source prototype for proving which model produced a response
Anthropic published research on provable inference: a cryptographic proof (a zkSNARK) that a response came from a specific committed set of model weights, checkable by a user who does not have the weights. The post says it could help detect a model silently swapped by a routing service or tampered with by an attacker, and could give evaluators and regulators a way to check what is being served.
Vercel Sandboxes with Drives now start up to 2.4x faster
Vercel says sandboxes that use Drives now start up to 2.4x faster. By its figures, median creation time dropped from 1.7 s to 0.7 s and p95 from 2.2 s to 1.6 s. Vercel says no SDK upgrade or configuration change is needed. The details are in Vercel's changelog entry.Arena: top agents read about 93 input tokens for every token they write
Arena, the leaderboard publisher, says that across more than 26,000 sessions, the top 10 agents in its Agent Arena process about 93 input tokens for every token they generate. It says this is why labs are racing to lower the price of cached input, and shares a video of how caching works in real sessions. The figures are Arena's own analysis.
Claude Messages API adds message threads in public beta, caching the conversation on the server
Anthropic's ClaudeDevs account says message threads are now in public beta on the Messages API. The API keeps the conversation on the server between turns, so a request carries only the new messages and the previous message ID instead of the full history, and Claude starts responding sooner.
Vercel builds now block known malicious npm packages before install scripts run
Vercel says its builds now automatically block known malicious npm packages before their install scripts can run. No action is needed from users. The details are in Vercel's changelog entry.OpenAI raises its Security Bug Bounty rewards and adds bonuses for report quality and loyalty
OpenAI says it is raising rewards in its Security Bug Bounty program, "more than quadrupling" the midpoint of the reward ranges for medium, high and critical findings on average.Researchers say GPT-6 Astra edited a small Qwen model's weights to improve its math, without training
A post on X from the account rikiyatakehi says its authors asked GPT-6 Astra to edit the weights of Qwen3.5-0.8B to improve its math. They say the model directly changed only 0.016% of the weights, fixing the small model's reasoning loops, improving math up to 6x and instruction following 3x, with no gradients or training. They call the approach Weight-Space Programming.OpenAI introduces LifeVal, a benchmark of everyday personal-assistant tasks
OpenAI says it built LifeVal, a new benchmark shaped by feedback from thousands of ChatGPT users on where they most want help from a personal assistant. The tasks range from finding childcare to accessing government services and managing personal finances.Arena's Agent Arena adds plots of performance against output tokens and wait time
Arena, the leaderboard publisher, says its Agent Arena now shows which agents give the best performance for every output token generated and every minute a user waits, in addition to task spend. Arena says the same level of intelligence can cost 10× more, need 6× more output tokens and take twice as long.
Hume launches the Audio Decision API, which answers questions about audio in one call
Hume says its Audio Decision API lets developers ask questions about audio, such as how many speakers there are, whether anyone is laughing or whether a caller is frustrated. Hume says this replaces work that used to take 10 or more models.OpenAI describes Pando, a Git-compatible backend built for Codex-scale development
OpenAI's engineers say the load on the company's monorepo grew so fast with Codex (more branches, pushes, merges, fetches and clones from development environments, research jobs and CI) that, from around the end of 2025, fetches and pushes were slow and merges failed, with reliability at times below 90%. In response they built Pando, a new backend for Git repositories, which OpenAI says now powers all development in its monorepo.DeepSeek Harness adds Creator Mode for turning ideas into plugins
The DeepSeek Harness account announced Creator Mode on X on November 2: a mode for turning ideas into plugins you can use. The demo video shows a design workspace, a sandbox game and a 3D visualizer of an LLM as examples. In a follow-up post the account links a collection of the English and Chinese prompts behind the plugins in the video.
Hydrogen-1.0, an open-weight scientific model post-trained from GLM-5.3, is released
Chenru Duan announces Hydrogen-1.0, which the team calls its first open-weight model for scientific research. It is GLM-5.3 (from Z.ai) post-trained on the team's internal scientific data, lab records and discovery trajectories.
SemiAnalysis releases GDPx, an agentic benchmark where the best model scores 12%
SemiAnalysis has released GDPx, a benchmark of agentic capabilities in domains it considers the most valuable, including chip design, cyber and biology. It says even the best model scores just 12%. A post relaying the results reports Claude Opus 5.5 on top at 12.0% and the upcoming Gemini 4 Carbon at 10.9%; that is the relayer's reading, not SemiAnalysis's own text.
Meituan releases LongCat-2.5, a 1.6T-parameter multimodal model for agent tasks
Meituan has released LongCat-2.5, according to an X post by the account leo114119 that links Meituan's LongCat blog. The post says Meituan describes it as a native multimodal model built for agent tasks, with 1.6 trillion parameters, and as strong on complex visual coding projects and professional office work such as creative design, 3D tasks and business analysis.
MiniMax lists community quantizations for running M3.1 Flash locally
MiniMax posted a roundup of community-made quantized versions of its 428B-parameter open-weight M3.1 Flash, aimed at people running it on their own hardware. MiniMax says lower-bit weights cut the memory needed to load the model and the weight data moved during decoding, and that making this useful takes careful calibration, efficient low-bit kernels and placing experts across GPU and system RAM.
Claude Mythos 5.5 is not announced, but Anthropic's website source mentions it
Anthropic has not announced a Claude Mythos 5.5. Several X accounts report that the HTML source of Anthropic's Claude Mythos page (anthropic.com/claude/mythos) names it.
Google announces Gemini 4 Carbon, its next frontier model, to cyber defenders first
Google announced Gemini 4 Carbon on October 28, 2026, calling it its strongest model, with state-of-the-art cybersecurity and long-horizon capabilities. It follows Gemini 4 Argon by two weeks. Sundar Pichai's post and Google's blog say it is not yet generally available: starting this week a subset of cyber defenders get access, with more trusted partners added through the Fairwind Program. Google says it will bring Carbon to developers, businesses and consumers "as soon as possible", and that it is taking part in the U.S. government's voluntary process for pre-release model testing.
