Anthropic's Claude 4 boasts significant improvements over its predecessors. It demonstrates enhanced reasoning, coding, and math capabilities alongside a longer context window allowing for up to 100,000 tokens of input. While still prone to hallucinations, Claude 4 shows reduced instances compared to previous versions. It's particularly adept at processing large volumes of text, including technical documentation, books, and even codebases. Furthermore, Claude 4 performs competitively with other leading large language models on various benchmarks while exhibiting strengths in creativity and long-form writing. Despite these advancements, limitations remain, such as potential biases and the possibility of generating incorrect or nonsensical outputs. The model is currently available through a chat interface and API.
Anthropic has released Claude 4, their latest large language model. This new model boasts significant improvements in performance across coding, math, reasoning, and safety. Claude 4 can handle much larger prompts—up to around 100K tokens, enabling it to process hundreds of pages of technical documentation or even a book. Its enhanced abilities are demonstrably better at standardized tests like the GRE, Code LeetCode, and GSM8k math problems, outperforming previous versions. Additionally, Claude 4 is more steerable, less prone to hallucination, and can produce longer and more structured outputs. It's now accessible through a chat interface and API, with two options: Claude-4-Instant for faster, lower-cost tasks, and Claude-4 for more complex reasoning and creative content generation.
Hacker News users discussing Claude 4 generally express excitement about its improved capabilities, particularly its long context window and coding abilities. Several commenters share anecdotes of successful usage, including handling large legal documents and generating impressive creative text formats. Some raise concerns about potential misuse, especially regarding academic dishonesty, and the possibility of hallucinations. The cost and limited availability are also mentioned as drawbacks. A few commenters compare Claude favorably to GPT-4, highlighting its stronger reasoning skills and "nicer" personality. There's also a discussion around the context window implementation and its potential limitations, as well as speculation about Anthropic's underlying model architecture.
