Launched in June 2024, 
Claude 3.5 Sonnet is a significant leap in AI technology, developed by Anthropic. It raises the bar for intelligence across various benchmarks such as 
graduate-level reasoning (GPQA), 
undergraduate-level knowledge (MMLU), and 
coding proficiency (HumanEval). This model is touted to be 
twice as fast as its predecessor, Claude 3 Opus, and offers a 
200K token context window, which is larger than GPT-4o's 128K token capacity. The model's pricing is also competitive at 
$3 per million input tokens and 
$15 per million output tokens. You can learn more straight from the
