📣 @OpenAIDevs's GPT-5.6 family is now generally available and rolling out in GitHub Copilot. GPT-5.6 comes in three variants: ☀️ GPT-5.6 Sol: the highest reasoning ceiling in the family. Best for complex reasoning over large codebases and demanding, long-running agentic work. 🌎 GPT-5.6 Terra: the balanced default. A strong all-round choice for everyday interactive and agentic coding. 🌕 GPT-5.6 Luna: a lightweight, cost-efficient variant for smaller, faster tasks and the lowest-cost option in the family. Try one, two, or them all in @code or the GitHub Copilot app. github.blog/changelog/2026…

@github @OpenAIDevs Having three variants lets Copilot match task difficulty to spend but the deeper change is the platform learning to route automatically instead of forcing developers to pick.

@github @OpenAIDevs they named the coding models after celestial bodies so when it breaks your build its cosmically inevitable

@github @OpenAIDevs Ok, but it still be much cheaper to use Codex directly.

@github @OpenAIDevs I sometimes miss coding and that aha moment when things worked and I was the reason for it. 🥲

@github @OpenAIDevs sol terra luna is a whole solar system arc lmao just let me pick the vibe and ship 💀

The wait is over. Securely trade crypto, with low costs and no hidden fees. Plus get expert insights from Morgan Stanley, all on one platform.

@github @OpenAIDevs Three variants for GPT-5.6 gives real flexibility on cost.

@github @OpenAIDevs Çok sinirliyim. Gpt 5.6 Sol yoktur. Biz Türkler olarak üvey evlat mıyız? Aynı parayı vermiyor muyuz😡

@github @OpenAIDevs Still not seeing it in the Copilot Enterprise model list in the AI Controls page :(

@github @OpenAIDevs

@github @OpenAIDevs Long agentic sessions have a different failure mode than 'reasoning ceiling' implies. The model starts acting on stale context from 40 tool calls back, confidently. Hit that mid-refactor more than once.

@github @OpenAIDevs ngl picking a model now feels like choosing a pokemon starter just let me vibe without commitment pls 😭

@github @OpenAIDevs Great to see GPT-5.6 rolling out in Copilot🐰 Choosing the right model for the task is becoming just as important as choosing the right tool.

@github @OpenAIDevs sol sounds intense

@github @OpenAIDevs Copilot 这波更新得实测一下了

Our delivery comes with a genius. Go learns what you like, builds your cart in seconds, and gets it all to your door in as fast as 15 minutes.

@github @OpenAIDevs Understanding when to use which model is important to save cost and money. Explained in the video. youtu.be/QKzgtHvOjhY?si…

@github @OpenAIDevs The Sol variant sounds like a game changer for large refactors. How are you all planning to integrate these new models into your existing workflows?

@github @OpenAIDevs The useful shift is keeping the model inside the repo loop: issue context, local edits, tests, and review in one place. Coding agents get a lot more valuable when the workflow is native, not a separate chat tab.

@github @OpenAIDevs 🔥🔥

@github @OpenAIDevs who r u?

@github @OpenAIDevs x.com/i/status/20753…

@github @OpenAIDevs And 5x times expensive? No, thanks

@github @OpenAIDevs Does it exist in every model, in every package?
