Product Updates

At Cloudflare, we’re big supporters of the open-source community – and that extends to our approach for Workers AI models as well. Our strategy for our Cloudflare AI products is to provide a top-notch developer experience and toolkit that can help people build applications with open-source models.We’re excited to be one of Meta’s launch partners to make their newest Llama 3.1 8B model available to all Workers AI users on Day 1. You can run their latest model by simply swapping out your model ID to @cf/meta/llama-3.1-8b-instruct or test out the model on our Workers AI Playground. Llama 3.1 8B is free to use on Workers AI until the model graduates out of beta.Meta’s Llama collection of models have consistently shown high-quality performance in areas like general knowledge, steerability, math, tool use, and multilingual translation. Workers AI is excited to continue to distribute and serve the Llama collection of models on our serverless inference platform, powered by our globally distributed GPUs.The Llama 3.1 model is particularly exciting, as it is released in a higher precision (bfloat16), incorporates function calling, and adds support across 8 languages. Having multilingual support built-in means that you can use Llama 3.1 to write prompts and receive responses directly in languages like English, French, German, Hindi, Italian, Portuguese, Spanish, and Thai. Expanding model understanding to more languages means that your applications have a bigger reach across the world, and it’s all possible with just one model.const answer = await env.AI.run('@cf/meta/llama-3.1-8b-instruct', { stream: true, messages: [{ "role": "user", "content": "Qu'est-ce que ç'est verlan en français?" }],});Llama 3.1 also introduces native function calling (also known as tool calls) which allows LLMs to generate structured JSON outputs which can then be fed into different APIs. This means that function calling is supported out-of-the-box, without the need for a fine-tuned variant of Llama that specializes in tool use. Having this capability built-in means that you can use one model across various tasks.

The modern use of "cloud" arguably traces its origins to the cloud icon, omnipresent in network diagrams for decades. A cloud was used to represent the vast and intricate infrastructure components required to deliver network or Internet services without going into depth about the underlying complexities. At Cloudflare, we embody this principle by providing critical infrastructure solutions in a user-friendly and easy-to-use way. Our logo, featuring the cloud symbol, reflects our commitment to simplifying the complexities of Internet infrastructure for all our users.This blog post provides an update about our infrastructure, focusing on our global backbone in 2024, and highlights its benefits for our customers, our competitive edge in the market, and the impact on our mission of helping build a better Internet. Since the time of our last backbone-related blog post in 2021, we have increased our backbone capacity (Tbps) by more than 500%, unlocking new use cases, as well as reliability and performance benefits for all our customers.A snapshot of Cloudflare’s infrastructureAs of July 2024, Cloudflare has data centers in 330 cities across more than 120 countries, each running Cloudflare equipment and services. The goal of delivering Cloudflare products and services everywhere remains consistent, although these data centers vary in the number of servers and amount of computational power.

Cloudflare Stream is an end-to-end solution for video encoding, storage, delivery, and playback. Our focus has always been on simplifying all aspects of video for developers. This goal continues to motivate us as we introduce first-class portrait (vertical) video support today. Newly uploaded or ingested portrait videos will now automatically be processed in full HD quality.Why portrait videoIn the past few years, the popularity of portrait video has exploded, motivated by short-form video content applications such as TikTok or YouTube Shorts.  However, Cloudflare customers have been confused as to why their portrait videos appear to be lower quality when viewed on portrait-first devices such as smartphones. This is because our video encoding pipeline previously did not support high-quality portrait videos, leading them to be grainy and lower quality. This pain point has now been addressed with the introduction of high-definition portrait video. The current stream pipelineWhen you upload a video to Stream, it is first encoded into several different “renditions” (sizes or resolutions) before delivery. This is done in order to enable playback in a wide variety of network conditions, as well as to standardize the way a video is experienced. By using these adaptive bitrate renditions, we are able to offer viewers the highest quality streaming experience which fits their network bandwidth, meaning someone watching a video with a slow mobile connection would be served a 240p video (a resolution of 320x240 pixels) and receive the 1080p (a resolution of 1920x1080 pixels) version when they are watching at home on their fiber Internet connection. This encoding pipeline follows one of two different paths:
