Haiku 5.5 is Great But GPT-6 Luna is Amazing: Which One To Use?

From the creator

Anthropic has released Claude Haiku 5.5 and the price is same as that of OpenAI's GPT-6 Luna. Codex 28 day challenge is going ahead with Day 3 giving a new ChatGPT intelligent UI, and we have some new decision models as well. First I explain what Claude Haiku 5.5 is, how its pricing works, and what tasks it is built for. Then we compare Haiku 5.5 and GPT-6 Luna test by test, from office work and computer use to coding, chart reading and how often each model makes things up. After that, we look at why the same price per token can give you three times the bill, how effort settings change the cost, and which model fits which kind of work. Next, I cover Day 3 of Tibo's 28 day Codex challenge, GPT-6 with Intelligent UI in ChatGPT, and the new usage reset. Then we see what decision models are, and how Cloudflare's Clef and Amazon's Strands Decider 2B compare with Jev. Finally, I give my honest take on these updates, and what caveats we need to consider. Subscribe to the channel, as I cover every update related to the top models, be it from the American or the Chinese AI labs.

AI Maker Residence 3 at KOKO

The third AI workshop taught by our legendary teacher, Nick Sarafa. In one of the last events we did an asset manager raised an additional £25M on their fund within a space of 9 months. This is a full-day hands-on training workshop for purposeful co-creation with AI using Claude Code. Imagine having access to hundreds of billions of dollars of computing power and knowing exactly how to make it work for you through the power of super intelligence. One person did.
