What changed in AI and data

gemini-4-argon became generally available on 13 October, the first Gemini 4 model in Google's API notes. The same day it reached the Gemini app for Google AI Pro and Ultra subscribers. Free accounts are not mentioned.

In October Databricks marked Knowledge Assistant and Supervisor Agent as legacy, 8 months after Supervisor Agent became generally available. It also published a guide to building agentsAgentA model that uses tools in a loop, deciding each next step from what the last one returned, until the task is done. in code with Agent Bricks.

From 12 October a fine-grained Hugging Face token can be given a contributor permission. It can create repositories and write to the ones it made, without write access to the other repositories around them. A script that uploads models no longer needs a token that can change everything.

On 8 October Google deprecated gemini-3.7-flash and gemini-3.5-flash. Calls to them now go to 3.8 Flash and 3.6 Flash. Your code keeps running, but on a different model, so check its answers.

Claude Haiku 5.5 came out on 7 October with a 1 million token context windowContext WindowEverything a model can see at once while it writes an answer, counted in tokens. When the window is full, something has to be left out.. It decides how long to think by itself, and returns an error if you send TemperatureTemperatureA setting that controls how much chance goes into each word a model picks. Low gives focused, predictable answers; high gives more varied ones., top_p, top_k, a thinking budget or a prefilled start of the answer. Code moving up from an older Haiku needs those removed.

From 7 October, reading cached text on Sonnet 5.5 costs $0.10 per million tokensTokenThe small piece of text a language model reads and writes, often part of a word. Prices, limits and the context window are all counted in tokens., down from $0.20. The same day, the Claude Max and Team plans began to include monthly API credits.

On 6 October OpenAI replaced its 5 usage tiers with 3: Build, Launch and Grow. Your account's rate limits come from its tier, so check where you landed.

Mistral released mistral-large-4 in public preview on 6 October, at 50% off for its first 2 weeks. Mistral says open weights are coming but has not released them yet.

xAI launched grok-4.7 in September with a 500,000 token context windowContext WindowEverything a model can see at once while it writes an answer, counted in tokens. When the window is full, something has to be left out., at the same prices as Grok 4.6. xAI's notes give the month only.

In September Google moved Gemini Live, Search Live and the voice features in Workspace to Gemini 3.8 Live, for every user. Google's roundup gives the month only.

Google released a Gemini app for Windows in September. Alt + Space opens it, and it can take on a task of several steps and work with your files from Gmail and Drive. Google's roundup gives the month only.

gpt-6-sol and gpt-6-luna came out on 22 September, and gpt-6.1-sol a week later, on 29 September. 3 new GPT-6 models in 4 weeks: pin the version your app was tested on.

Claude Sonnet 5.5 came out on 28 September. 2 days later Anthropic set 30 November 2026 as the retirement date for Claude Sonnet 4.5. If an app still runs on claude-sonnet-4-5-20250929, it has 2 months.

Claude Opus 5.5 came out on 22 September at $4 per million input tokens and $20 per million output tokens, down from $5 and $25 for Opus 5. It always thinks, and you cannot turn that off.

From 22 September, Transformers can load the compact quantizedQuantizationStoring a model's numbers with less precision, such as 4 bits instead of 16, so it needs far less memory and can run on smaller hardware, at some cost in accuracy. GGUF files made for llama.cpp, so a model sized for a laptop runs from the usual Python code. For now it needs the newest unreleased Transformers, and its fast path works only on Apple Silicon Macs and with Qwen models so far. Hugging Face still recommends llama.cpp when speed on your own machine matters most.

From 18 September, only people who already used the Gemini 2.5 models can call them. The models are not deprecated, but a new project cannot start on them.

DeepSeek released V4.1 Flash on 10 September, the smallest model in its new family, which reads images as well as text, and lowered its API prices. The old V4 Flash names now answer with V4.1 Flash for a while.

OpenAI released its Agents API in public beta on 10 September, and added computer use to it on 29 September. It is OpenAI's own place to run an AgentAgentA model that uses tools in a loop, deciding each next step from what the last one returned, until the task is done., after it announced the end of Agent Builder in June.

gpt-6-astra, the first GPT-6 model in OpenAI's changelog, came out on 3 September. You can steer it in the middle of a turn, change how hard it thinks mid-conversation, and let its tool calls run while it keeps working.

gemini-3.8-flash became generally available on 2 September, 3 weeks after 3.7 Flash.

Claude Fable 5.1 and Claude Mythos 5.1 came out on 1 September at $10 per million input tokensTokenThe small piece of text a language model reads and writes, often part of a word. Prices, limits and the context window are all counted in tokens. and $50 per million output tokens. Like Fable 5, both need 30-day data retention and are not offered under zero data retention unless Anthropic expressly allows it. If your company needs zero retention, check this before you switch.

xAI launched grok-4.6 in August with a 500,000 token context windowContext WindowEverything a model can see at once while it writes an answer, counted in tokens. When the window is full, something has to be left out.. Its price doubles once a prompt passes 200,000 tokens, so a long prompt costs more per token than a short one. xAI's notes give the month only.

The Assistants API shut down on 26 August. OpenAI also set 26 February 2027 as the end for whisper-1 and the GPT-4o transcription models. If you turn speech into text with them, you have about 6 months to move.

From 21 August gpt-5.6-sol costs $4 per million input tokens and $20 per million output tokens. OpenAI calls it promotional pricing, held at least until 21 November 2026.

On 19 August Claude's computer use tool left beta, and a new browser use tool arrived. An AgentAgentA model that uses tools in a loop, deciding each next step from what the last one returned, until the task is done. now has a tool made for working in web pages. The Files and Skills APIs left beta the same day.

DeepSeek V4-Pro became generally available on 13 August. From 16 August, DeepSeek charges half price outside its peak hours. If a job can wait, run it off-peak. DeepSeek gives the hours in its notice for the change, linked from its news page.

gemini-3.7-flash became generally available on 13 August, with an introductory price that runs to 31 December 2026. Plan for the price to change after that.

On 10 August Anthropic cancelled the planned rise of Claude Sonnet 5 to $3 and $15 per million tokensTokenThe small piece of text a language model reads and writes, often part of a word. Prices, limits and the context window are all counted in tokens.. It stays at $2 per million input tokens and $10 per million output tokens.

Claude Opus 4.1 retired on 5 August, 2 months after Anthropic announced it. Calls to claude-opus-4-1-20250805 now fail.

In July Databricks moved its Genie products to pay-as-you-go pricing and renamed Genie Spaces to Genie Agents. If your team uses Genie, its cost now follows its use.

On 30 July gpt-5.6-luna became 80% cheaper and gpt-5.6-terra 20% cheaper. Priority Processing became Fast mode, which runs gpt-5.6-sol up to 2.5 times faster at twice the price. Check whether a job you run on Sol could run on Luna.
