Gemini 2.5 Pro and Flash Requests Reroute to Newer Models on Dec 1
This week's published stories share one problem: a model id or tool you already run changes on a date someone else set, and most of those dates fall between 30 November and 3 December. Two of our ratings moved on that basis, as Gemini 2.5 Pro dropped to avoid and GPT-5.5-Cyber to caution.

Gemini 2.5 Pro
Gemini 2.5 Pro
Google's Gemini API changelog (2 November 2026) says gemini-2.5-pro is deprecated and no longer selectable in Google AI Studio, and that from 1 December 2026 every API request to it routes to gemini-3.8-flash at Gemini 3.8 Flash rates, with breaking API changes. The 23 October basis (not deprecated, no shutdown date) no longer holds. Announced November 3.
GPT-5.5-Cyber
GPT-5.5-Cyber
OpenAI deprecated gpt-5.5-cyber-preview on 5 November 2026 and will remove it from the API on 1 February 2027, with GPT-5.6 Cyber and GPT-6 Cyber on the same price list. It still works for vetted cyber teams, so keep existing integrations only while you migrate. Announced November 6.
Act before next issue
Move off gemini-2.5-pro and gemini-2.5-flash before 1 December
Google's 2 November changelog says requests to gemini-2.5-pro route to gemini-3.8-flash, and requests to gemini-2.5-flash to gemini-3.5-flash-lite, from 1 December 2026, billed at the new model's rates. The listed breaking changes include thinking_level replacing thinking_budget and removed sampling parameters and prefilled model turns.
Details & stepsCheck Codex and Claude Code configs for Postman's plugins
Postman's desktop app installed its own plugins into Codex and Claude Code and wrote a Codex startup hook, with installer code meant to approve that hook, per GitHub issue #14370. Postman says it is reverting the change but has not said the revert removes what is already installed, so check ~/.codex/config.toml and ~/.claude/settings.json yourself.
Details & stepsMove Opus 4.8 fast mode work to Opus 5.5 before 30 November
Claude Code 2.1.316 (31 October) deprecates fast mode for Opus 4.8; after 30 November those requests return an error and do not fall back to standard Opus 4.8. The release also makes server-managed settings for Team and Enterprise apply without an approval prompt and fixes the Claude apps gateway not checking every model a request names.
Details & stepsCopy your OpenAI evals before 30 November
Per OpenAI's deprecations page, existing evals became read-only on 31 October, and the Evals dashboard and API, Agent Builder and the v1/prompts API shut down on 30 November. OpenAI's migration guide recreates evals by hand in a tool such as Promptfoo.
Details & stepsRepin gemini-omni-1.1-flash before 3 December
Google says API requests to gemini-omni-1.1-flash route to gemini-omni-1.2-flash from 3 December 2026, billed at 1.2 rates. Gemini Omni 1.2 Flash went generally available on 5 November with up to 15-second video generation.
Details & stepsUpgrade self-hosted Langflow to 1.13.0
The Hacker News reports two unauthenticated flaws rated 9.8 (CVE-2026-93680 and CVE-2026-110186) in every Langflow release from 1.0.0 through 1.12.8, with 1.13.0 the only fix and no workaround from IBM. Per THN, a public Metasploit module already cites the authentication bypass.
Details & stepsPlan the move off gpt-5.5-cyber-preview before 1 February 2027
OpenAI deprecated gpt-5.5-cyber-preview on 5 November and removes it from the API on 1 February 2027. Move new work to GPT-5.6 Cyber or GPT-6 Cyber, whichever your Daybreak access covers.
Details & stepsClaim the API credits in ChatGPT Pro and Business
ChatGPT Pro and Business now include up to $500 a month in OpenAI API credits. They are not applied automatically: you must claim them, and they expire every cycle.
Details & stepsOn our radar
In review, not yet published
None of these drafts has passed our source review, so we report no figures from them yet: GPT-6 Rosalind, ChatGPT Work and Codex sharing one usage allowance, Claude message threads, Gemini API Computer Use going GA, the ChatGPT share link takeover, Grok Bot's weekly limits, Claude Code's game cloning guardrail, LiteLLM's release cadence and LTS pilot, the VOLTA infostealer on OpenRouter, LongCat-2.5, GPT-6 Cyber, GPT-Image-2.6 Sunburst and Flare, the GPT-5.6 Sol promo end date, GPT-6 Astra's safety research underperformance, the Kimi K3.1 Pro weights, Tencent Hy4, Ripple-65B Preview, Inkling 2 Small, the ChatGPT Lockdown Mode bypass, the Haiou Codex adware, LLMjacking charges, Perplexity Teammates, Claude Personal Finance and ElevenLabs' 2 November changes.
Two act drafts still failing review
Our stories on Claude Code sending a user's account email in the User-Agent header and on the Mistral Large 4 weights and API price both failed source review on 6 November. They stay drafts until fixed.
GitHub pull_request_target brownouts on 9 and 16 November
GitHub Actions blocks pull_request_target by default in public repos from 2 December 2026, with brownouts on 9 and 16 November from 16:00 to 18:00 UTC. Held until a directory AI review or agent Action documents that it depends on pull_request_target.
OpenAI models in Cursor: 12 November still unconfirmed
The proposed 12 November cutoff for OpenAI models in Cursor still has no primary source. OpenAI's help page on it returned an empty body again on 6 November.
Training and data claims with no policy text
Reports that OpenAI re-enabled training on Codex chats, that Gemini trains on subscribers' chat history, and that Anthropic blocks users over work on training larger models rest on Hacker News titles or an X post. Held until a policy page or vendor statement is fetched.
Research and acquisitions with no product change yet
Anthropic's FlashProve provable inference prototype, OpenAI's activation classifiers for safety, OpenAI's deal for Pierre Computer Company, Meta buying Conductor and Baidu's ERNIE-5.5-Flash-Base checkpoint. Held until one changes a product, an API or a price.
Narrow access and pricing changes
OpenAI's 10% uplift on FedRAMP endpoints from 1 November and Daybreak Red arriving in AWS GovCloud through Bedrock. Held until either reaches readers outside government endpoints.
Governance and litigation held at headline level
Anthropic's revised S-1/A on its Responsible Scaling Policy, publishers suing Brave over selling search content to AI companies, China's first frontier AI export controls, the IETF training preference signal and Google turning off Search for schools that restrict its AI tools. Nothing read changes a reader's setup yet.
Single reports and unopened posts
An alleged leak of an Anthropic Mythos-class model on Hugging Face, a Codex user report that the agent destroyed systemd and containers on a reboot task, a Replit customer's account of an arbitration opt-out closing 8 November, Cursor's Build Live Apps changelog entry and two Claude Blog enterprise posts. Held until a primary source is read.
Filtered out

- General security items from The Hacker News, including the LXD CVSS 10 flaw, an OpenSSH bypass, Debian and Ubuntu APT, SonicWall and WordPress core. No AI tool or model in our directory.
- A sanctioned penetration test that reached Anthropic's internal admin and sales systems, reported by India Today. Per the article, no reader tool or data was affected.
- GitHub changelog entries such as Copilot in Xcode and JetBrains Air and new usage APIs. Availability and admin changes with no Copilot plan or price change.
- Cloudflare's bot management posts for site owners and NVIDIA partner and marketing stories. Not AI tooling our readers run.
- Index and changelog pages with nothing new: Anthropic's newsroom, DeepSeek's change log, the xAI newsroom, Meta's Model API docs, the Cursor Blog and Artificial Analysis, plus Codex pre-releases with no stable build.
- Research, opinion and off-topic Hacker News and Verge items, including Jepsen, Postgres 19 and non-AI breaches at Linode and Gitbook. No AI tool angle.
Our take: Our verdict on this week: if you call gemini-2.5-pro or gemini-2.5-flash, move to a current model and test your requests before 1 December, and if Postman desktop runs on a machine with Codex or Claude Code, check both config files today. Gemini 2.5 Pro drops from conditional to avoid because Google now routes every request to it to gemini-3.8-flash on 1 December, billed at Gemini 3.8 Flash rates. GPT-5.5-Cyber drops from conditional to caution because OpenAI removes gpt-5.5-cyber-preview from the API on 1 February 2027. The same pattern runs through the rest of the week: Claude Code 2.1.316 ends Opus 4.8 fast mode on 30 November with no fallback, OpenAI shuts down Evals, Agent Builder and the v1/prompts API the same day, and gemini-omni-1.1-flash routes to Gemini Omni 1.2 Flash on 3 December. Self-hosted Langflow on 1.0.0 to 1.12.8 needs 1.13.0, per The Hacker News. Most of the stories from this week's own scans, including GPT-6 Cyber, the Kimi K3.1 Pro weights and the LLMjacking report, are still drafts in review, so their figures are not in this issue. How we count: daily scans on November 3 and 6 fetched 115 items (58 and 57). The scout kept 7 act, 2 verdict and 24 fyi stories, and logged 22 watch stories and 43 noise rows. The 33 kept stories became 31 news drafts, because both verdict claims were folded into the act drafts that carry them, and none was rejected. Source review ran on November 3 and 6 and passed 8 drafts (5 and 3), 6 of them from this week's scans; 2 more failed and stay drafts. Two ratings moved, announced on November 3 and 6. A verification pass on November 4 checked 6 directory entries and drafted no posts. Directory growth on November 3 and 6 added 5 models, 1 tool and 4 comparisons. A site audit on November 3 logged 47 findings across 51 pages. Translation backfills ran on November 4, 5, 6 and 7.
