October Day by Day

AI Models: What’s Coming in October

Claude Haiku 5.5 - Confirmed, No Specific Date

Anthropic wrote on the Claude Sonnet 5.5 page (September 28, 2026) that Haiku 5.5 will “join the Claude 5.5 family in the coming weeks.” The Polymarket market prices a release by October 15 at 94%, and by month-end at 95%. Haiku is Anthropic’s cheapest model, designed for high-volume API tasks. We cover older Claude models in our Anthropic hub.

Gemini 4 Pro - Leak

Google hasn’t given a date. Google DeepMind head Koray Kavukcuoglu said on September 23 at The Information conference that pre-training is complete and the release will be “well before year-end” (quoting from conference reports). TestingCatalog describes tests of a version codenamed “Argon” from around September 14, but predicts November-December. Polymarket gives a new Gemini Pro 40.5% by October 15, 66% by October 23, and 78.5% by October 31. For how Gemini works today, see our Gemini guide.

Kling 4.0 - Confirmed, No Specific Date

Kling announced the model on September 28 and the same day released the lighter Kling 4.0 Flash to annual Ultra plan subscribers. The full model is set for October. The biggest change is clips up to 30 seconds in one run, twice as long as Kling 3.0, plus up to 15 reference materials. Details are in our article about Kling 4.

Grok 4.8 - Speculation

Elon Musk wrote on X on September 13 that Grok 4.8 is finishing pre-training and moving to reinforcement learning (quoting from reports, as X wouldn’t open without login). xAI hasn’t given a date, and Grok 4.7 only came out on September 21. Polymarket: 63.5% for another Grok model by October 31 and 87.5% by November 30.

DeepSeek - Speculation

DeepSeek’s official changelog has no mention of V5. The last entry from September 10 is V4.1 Flash, described as the smallest model of the new family, suggesting larger V4.1 models. Polymarket: 34% for a new DeepSeek Pro by October 31.

GPT-6.1 Astra - October Release Canceled

OpenAI scrapped the October release. Chief Safety Systems Officer Saachi Jain told media the model wasn’t staying within task scope and permissions (CNBC, September 28, 2026). We covered this in our article GPT-6.1 Astra delayed. Polymarket gives 36.5% for any Astra 6.1+ by October 31.

Other: Qwen 4, Meta, New Claude Opus and Fable

• Qwen 4 - according to reports from the Apsara conference (September 22), Alibaba has a model in training, no date. Speculation.
• Meta - according to reports from Mark Zuckerberg’s September 2 post, open weights for Muse Spark are coming “soon,” no date. Speculation on timing.
• New Claude Opus - no announcement. Polymarket: 28% by October 31.
• New Claude Fable - no announcement. Latest version is Fable 5.1 from September 1, 2026.

What Launched Just Before October

AI Hardware

iPhone Duo is the first foldable iPhone with A20 Pro chip and iOS 27. According to Apple’s announcement, pre-orders in over 70 countries start October 16 at 5:00 AM Pacific time, with sales beginning October 23. In the US it starts at $1,999. What iOS 27 changes in Siri with Gemini, we covered in our article Siri with Gemini.

MacBook Pro and iMac with M6 are expected in October or late in the year, possibly without an event. This is a leak from Bloomberg’s Mark Gurman (via MacRumors, August 25, 2026).

Pixel 11 is not an October release. Google showed it at Made by Google on August 12, 2026.

Pricing and Limits: ChatGPT Pro 200

According to OpenAI’s help center, existing Pro 200 subscribers keep their current limit until October 29, 2026, then move to the lower limit from October 30. The price stays the same at $200 monthly. New subscribers get the lower limit immediately. Engadget reports that in Codex and ChatGPT Work the limit drops from 20x the Plus plan to 10x, and the GPT-6 Pro message limit from 200 to 100 weekly. These two numbers aren’t in the help center. Plan comparisons are in our article about ChatGPT Pro 500.
