OpenAI, which declared a "code red (emergency)" due to competitors' pursuit, has acquired an artificial intelligence (AI) startup to improve ChatGPT. OpenAI announced on the 3rd (local time) that it would acquire Polish AI startup Neptune.

OpenAI has agreed to acquire Neptune, a startup that provides tools that help companies track their AI model training, the ChatGPT maker said on Wednesday. While OpenAI did not disclose the financial terms of the deal,

That mainstream deployment shaped user expectations in a way that later transitions struggled to accommodate. In August 2025, when OpenAI initially replaced GPT-4o with its much anticipated then-new model family GPT-5 as ChatGPT’s default and pushed 4o into a “legacy” toggle, the reaction was unusually strong.

So, bottom line, if OpenAI can substantially reduce the cost of API calls and still deliver AI value, as it seems to have done with GPT-5.1, there's a much better chance it can make the case for including GPT-5.1 in developers' products.

GPT-5.1 Instant is able to leverage newfound “adaptive reasoning” capabilities to determine when it needs to think more carefully about its responses, such as when someone enters a more complex prompt. Improvements have also been made to its instruction following skills, so it will directly address user’s queries with more consistency than before.

OpenAI characterizes GPT-5.1-Codex-Max as the company’s first coding model explicitly trained to operate across multiple context windows through a technique called compaction. The model can maintain coherent reasoning across millions of tokens, enabling tasks that traditionally exceeded AI systems’ memory limits.

OpenAI is testing another new way to expose the complicated processes at work inside large language models. Researchers at the company can make an LLM produce what they call a confession, in which the model explains how it carried out a task and (most of the time) owns up to any bad behavior.

OpenAI makes revenue from premium subscriptions to ChatGPT but most users get the free version. The company introduced its own web browser, Atlas, in October, an attempt to compete with Google's Chrome as more internet users rely on AI to answer their questions.
