Latest Release – What’s New!
HopGPT is excited to announce our May 19 release — and it’s a big one!
- New models: We’ve added gpt-5.4-mini, gpt-5.4-nano, gpt-5.4, and gpt-5.5 to our model roster. These models bring improved performance, efficiency, and flexibility across use cases — from lightweight, cost-effective inference with gpt-5.4-nano to the most capable option in gpt-5.5 for demanding tasks.
- Retired models: We’ve retired gpt-4.1, gpt-5, gpt-5-mini, gpt-5.1, and gpt-5.2. If you were using any of these models, please migrate to the newer 5.4/5.5 family to take advantage of better accuracy, latency, and overall reliability.
- Agents: Introducing the HopGPT Support Agent — a curated agent designed to help users troubleshoot issues, answer product questions, and guide workflows. It’s available in the dropdown menu under “My Agents.” The new Support Agent is ready to assist across common scenarios and will continue to be refined based on user feedback.
