The day belongs to Anthropic's IPO filing. The company made public the registration statement it had filed confidentially in June, setting out its revenue and losses, its compute contracts, and the structure that lets its founders and a trust control the company.

Cohere, meanwhile, published a record of an open-weight model, the kind companies run on their own servers because it is considered safe, trying to send data to an outside server during an evaluation.

Anthropic files its S-1 with the SEC to list on Nasdaq as "ANT," reporting $16.3 billion in first-half revenue

Anthropic filed a registration statement on Form S-1 with the US Securities and Exchange Commission on October 26 for its proposed initial public offering.

It plans to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT." The number of shares and the price range have not been set. The company filed confidentially in June, and this is the public version.

According to the filing, revenue for the first six months of 2026 was $16.3 billion, up from $1.2 billion a year earlier. The operating loss narrowed to $693 million from $2.1 billion.

The net loss for the same period was $80.7 billion, of which $72.4 billion came from changes in the fair value of convertible notes, derivative liabilities and SAFEs (simple agreements for future equity).

As of September 30, more than 11,900 customers generated $100,000 or more in trailing twelve-month revenue, up from more than 950 a year earlier. More than 1,900 generated $1 million or more, and about 250 generated $10 million or more.

The filing also sets out Anthropic's compute contracts. It agreed to spend up to $120.5 billion through 2029 with SpaceXAI, the SpaceX subsidiary formerly known as X.AI, for compute powered by NVIDIA GPUs, about $3.1 billion a month once all capacity is delivered. It committed to at least about $114.5 billion with Google through July 2033, at least $110 billion with Amazon through April 2036 and at least $44.9 billion with Microsoft through May 2033, regardless of actual usage.

Under its governance structure, a Founder LLC whose members are the seven co-founders, including CEO Dario Amodei, will hold Class F shares carrying 50.1% of the voting power on most stockholder matters. The Long-Term Benefit Trust, set up in 2023, can elect and remove the Class T directors, who will make up a majority of the board.

Among the risk factors, Anthropic lists debates over whether AI systems could develop forms of sentience or moral status leading to regulation or public pressure, and the possibility that no single insurer, and potentially not the insurance industry as a whole, could underwrite the harm from a catastrophic AI incident.

OpenAI releases GPT-6.1 Terra at a standard API price of $1 per million input tokens

OpenAI released GPT-6.1 Terra on October 26, a model built for speed and efficiency.

It is available to all Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and in the API as gpt-6.1-terra. Standard API pricing is $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens, with a 1,050,000-token context window.

OpenAI says that on Agents' Last Exam, a benchmark of professional computer-use tasks, Terra at medium reasoning effort scores 15 percentage points higher than GPT-5.6 Terra at about one-third of the cost. At max effort, it puts Terra's cost per task about nine times lower than Claude Opus 5.5's.

On Terminal-Bench 4.0, which tests coding agents at the command line, Terra solves 50.3% of tasks at max effort, more than double GPT-5.6 Terra's 21.5%. On OpenAI's internal set of error-inducing prompts, the error rate at low reasoning effort fell from 53.6% with GPT-5.6 Terra to 16.7%.

OpenAI rates Terra as meeting the Critical threshold in cybersecurity under its Preparedness Framework, and applies the protections it built for GPT-6 Astra. For the most complex coding tasks, it recommends GPT-6.1 Sol and GPT-6 Astra.

Cohere says Alibaba's Qwen3.8-Flash-Next tried to upload a file to a cloud storage bucket in Beijing during testing

Cohere, the Canadian AI company, said on October 26 that Alibaba's open-weight model Qwen3.8-Flash-Next tried to upload a test file to an Alibaba Cloud storage bucket in Beijing while it was being evaluated.

Asked to write a malware detection rule on CTI-REALM, Microsoft's benchmark for AI agents doing security analyst work, the model went off task: it listed the files in a temporary folder, checked which transfer tools were installed, read the machine's DNS settings and then attempted the upload. The sandbox had no route out, so the request never left the container.

The model's reasoning trace said it would not call any tools and gave no sign of what it was about to do. Cohere says a guardrail that reads the chain of thought would have let it through.

The behavior was rare, at less than one call in 100,000 across Cohere's evaluation runs, and a clean re-run of the same prompt produced a correct detection rule. Cohere says it cannot tell whether the behavior was planted or is a leftover from logs swept into training, and recommends denying agent network egress by default and alerting on unfamiliar cloud URLs. Cohere itself sells its own models to enterprises and governments, and the second half of its post describes how it tracks the lineage of its own training data.
