AI researcher says 'world is in peril' and quits to study poetry
AI researcher says'world is in peril' and quits to study poetry An AI safety researcher has quit US firm Anthropic with a cryptic warning that the world is in peril. In his resignation letter shared on X, Mrinank Sharma told the firm he was leaving amid concerns about AI, bioweapons and the state of the wider world. He said he would instead look to pursue writing and studying poetry, and move back to the UK to become invisible. It comes in the same week that a OpenAI researcher said she had resigned, sharing concerns about the ChatGPT maker's decision to deploy adverts in its chatbot . Anthropic, best known for its Claude chatbot, had released a series of commercials aimed at OpenAI, criticising the company's move to include adverts for some users.
SoftBank swings to profit on valuation boost from OpenAI bet
SoftBank CEO Masayoshi Son and OpenAI CEO Sam Altman attend an event in Tokyo in February 2025. SoftBank's investment gain on OpenAI stood at an estimated $19.8 billion as of December. SoftBank Group sprang back to a quarterly profit after Masayoshi Son's bet on OpenAI paid off in valuation gains, cementing the Japanese company's position as an investment proxy for the ChatGPT creator. The Tokyo-based company has invested more than $30 billion (ยฅ4.58 trillion) in OpenAI, accumulating an 11% stake as of December, and has been in talks to invest as much as $30 billion more in a round that would value the startup at about $750 billion to $830 billion. As of December, SoftBank's investment gain on OpenAI stood at an estimated $19.8 billion, the company said Thursday.

They are used in our experiments section. OpenAI GPT -4 based prompts The input template for OpenAI GPT -4 is defined as: Please describe the appearance of [class_name] in endoscopic surgery, and change the description to a phrase with subject, and not use colons. The dataset consists of both training and test cases. Each video is recorded at 25 FPS and has annotations for instruments and operation phases. For EndoVis2019, the results are shown in Tab. 1, our method (input size 448) notably surpasses the competition's top performers, with +3% increase in DSC and +2% enhancement in NSD, which demonstrates the superiority of our method.
Anthropic beefs up Claude's free tier as OpenAI prepares to stuff ads into ChatGPT's
Samsung Galaxy Unpacked 2026 is Feb. 25 Valve's Steam Machine: Everything we know Anthropic beefs up Claude's free tier as OpenAI prepares to stuff ads into ChatGPT's You no longer need a subscription to create files or use Connectors and Skills in Claude. Anthropic is upgrading Claude's free tier, apparently to capitalize on OpenAI's planned integration of ads into ChatGPT . On Wednesday, Anthropic said free Claude users can now create files, connect to external services, use skills and more. Anthropic added the ability for paid users to create files in September. Starting today, free users of the chatbot can also create and edit Excel spreadsheets, PowerPoint presentations, Word docs and PDFs.

KAN oversaw the project and contributed valuable feedback. MindEye was developed using a training and validation set of Subject 1's data, with the test set (and other subjects' data) untouched until final PyTorch code for the MLP backbone and projector is depicted in Algorithm 1. Specifics on how we DALL-E 2. This makes our prior much faster at inference time. For simplicity we use bidirectional attention in our final model. To map to Stable Diffusion's V AE latent space we use a low-level pipeline with the same architecture as the high level pipeline. Recent works in low-level vision (super-resolution, denoising, deblurring, etc.) have observed that This performs worse than only applying the loss in latent space and also requires significantly more GPU memory.
