Summary

OpenAI merged ChatGPT and Codex into one platform with three new models (GPT-5.6 Soul, Terra, Luna), positioning it as a productivity tool for 983 million users who don't realize ChatGPT's full capabilities. GPT-5.6 Soul is token-efficient and faster at long-running tasks than competitors, though it's a version bump, not yet a Grok competitor.

Key Takeaways

  1. GPT-5.6 Soul is 70% more token-efficient than previous versions and requires fewer tool calls than Gemini, which 'spirals into hell' by calling 15-20 different tools unnecessarily.
  2. The 'Work' tab targets the 983 million ChatGPT users who perceive it as just a chat tool, not a productivity platform. This addresses a critical awareness gap where users think Claude is the only 'agentic platform.'
  3. GPT-5.6 executes multi-step plans autonomously without asking for confirmation at each phase, unlike GPT-5.5 which was 'very needy' and required manual intervention between phases.
  4. GPT-5.6 can build production apps in one shot (e.g., a Lovable clone using Swift, Daytona, Convex, and Anthropic models), though it requires longer, more detailed prompts than Grok.
  5. GPT-6 (full version) will be the true Grok competitor—GPT-5.6 is positioned as an incremental upgrade bridging the gap between 5.5 and the next major model release.

OpenAI just combined Codeex and ChachiBT into one super app. And they also released a new model that's nearly as good as Fable. They also made updates to their sites feature which turns it into a full vibe coding platform. And they made updates to their in-app browser. And so I have so many questions about all of this and how this actually works. So today I'm bringing on Ross Mike and we're going to break down all the new models, how the new platform works, and how he uses Codeex as a developer and how I use it as a marketer and founder. You're watching Agent Native. My name's Riley Brown. Let's dive in. Ross Mike, here we are. We're in the new Chat GPT app, which used to be Codeex. OpenAI decided to merge chat GBT and Codeex and also introduce three new models, one of which is very close …
