 ## Updates
 
 - **2024-05-15**: We introduced a new endpoint `s.jina.ai` that searches on the web and return top-5 results, each in a LLM-friendly format. [Read more about this new feature here](https://jina.ai/news/jina-reader-for-search-grounding-to-improve-factuality-of-llms).
-- **2024-05-08**: Image capion is off by default for better latency. To turn it on, set `x-with-generated-alt: true` in the request header.
+- **2024-05-08**: Image caption is off by default for better latency. To turn it on, set `x-with-generated-alt: true` in the request header.
 - **2024-05-03**: We finally resolved a DDoS attack since April 29th. Now our API is much more reliable and scalable than ever!
 - **2024-04-24**: You now have more fine-grained control over Reader API [using headers](#using-request-headers), e.g. forwarding cookies, using HTTP proxy.
 - **2024-04-15**: Reader now supports image reading! It captions all images at the specified URL and adds `Image [idx]: [caption]` as an alt tag (if they initially lack one). This enables downstream LLMs to interact with the images in reasoning, summarizing etc. [See example here](https://x.com/JinaAI_/status/1780094402071023926).
