HN commenters express skepticism about the existence of GPT-4.5, pointing to the lack of official confirmation from OpenAI and the blog post's removal. Some suggest it was an accidental publishing or a controlled leak to gauge public reaction. Others speculate about the timing, wondering if it's related to Google's upcoming announcements or an attempt to distract from negative press. Several users discuss potential improvements in GPT-4.5, such as better reasoning and multi-modal capabilities, while acknowledging the possibility that it might simply be a refined version of GPT-4. The overall sentiment reflects cautious interest mixed with suspicion, with many awaiting official communication from OpenAI.
Mistral AI has released Saba, a new large language model (LLM) exhibiting significant performance improvements over their previous model, Mixtral 8x7B. Saba demonstrates state-of-the-art results on various benchmarks, including reasoning, mathematics, and code generation, while being more efficient to train and run. This improvement comes from architectural innovations and improved training data curation. Mistral highlights Saba's robustness and controllability, aiming for safer and more reliable deployments. They also emphasize their commitment to open research and accessibility by releasing smaller, research-focused variants of Saba under permissive licenses.
Hacker News commenters on the Mistral Saba announcement express cautious optimism, noting the impressive benchmarks but also questioning their real-world applicability and the lack of open-source access. Several highlight the unusual move of withholding weights and code, speculating about potential monetization strategies and the competitive landscape. Some suspect the closed nature might hinder community contribution and scrutiny, potentially inflating performance numbers. Others draw comparisons to other models like Llama 2, debating the trade-offs between openness and performance. A few express excitement for potential future open-sourcing and acknowledge the rapid progress in the LLMs space. The closed-source nature is a recurring theme, generating both skepticism and curiosity about Mistral AI's approach.
Anthropic has launched a new Citations API for its Claude language model. This API allows developers to retrieve the sources Claude used when generating a response, providing greater transparency and verifiability. The citations include URLs and, where available, spans of text within those URLs. This feature aims to help users assess the reliability of Claude's output and trace back the information to its original context. While the API strives for accuracy, Anthropic acknowledges that limitations exist and ongoing improvements are being made. They encourage users to provide feedback to further enhance the citation process.
Hacker News users generally expressed interest in Anthropic's new citation feature, viewing it as a positive step towards addressing hallucinations and increasing trustworthiness in LLMs. Some praised the transparency it offers, allowing users to verify information and potentially correct errors. Several commenters discussed the potential impact on academic research and the possibilities for integrating it with other tools and platforms. Concerns were raised about the potential for manipulation of citations and the need for clearer evaluation metrics. A few users questioned the extent to which the citations truly reflected the model's reasoning process versus simply matching phrases. Overall, the sentiment leaned towards cautious optimism, with many acknowledging the limitations while still appreciating the progress.
