⚡ Fast mode
Need an answer now? Flip on fast mode in the model picker to push Opus models to 2.5x faster token output, at increased usage.
The boost is most dramatic on long blocks of pure token output: big explanations, large blocks of code, or heavy reasoning. Questions that require a lot of querying and tool calls will still feel faster, just less dramatically, since a chunk of that time is calls and execution rather than token generation.
🧠 GPT-5.6 Sol, Terra, and Luna
OpenAI's GPT-5.6 family is now in the model picker:
- Sol for complex, multi-step analytical work
- Terra for balanced everyday use
- Luna for fast, low-cost lookups
Select one when you're prompting the agent, or keep Auto on, which automatically selects the model best suited for the task.
✅ Default new Threads to Endorsed mode
New threads from the Hex UI or Slack can now open in Endorsed Mode by default, so Editors land in endorsed projects and data without anyone having to remember to flip a switch. Admins can toggle off this enforcement in Settings > AI & agents.
🏷️ See which model Auto picked
When the agent runs on Auto, Context Studio now shows which model it picked, shown as Auto (Opus 4.7), making it easy to see what Auto chose when reviewing usage and cost.
