Since OpenAI stopped new ChatGPT group chats on 9 July 2026, Bordet is a group chat alternative where your team and AI models from several labs (GPT, Claude, Gemini, Grok) work in one conversation. The room keeps one shared memory and a decisions log, so the next session starts where the last one ended.
ChatGPT is still the best-known assistant, and in 2026 a serious workspace: OpenAI's latest models, a memory you can inspect, agents that run tasks, and Projects that hold files and instructions. Projects can now be shared, so colleagues see the same chats and files. What went away is the group chat itself: OpenAI ran it as a pilot from November 2025 and began retiring it on 9 July 2026. No new group chats can be created, and existing ones are becoming read-only.
So a ChatGPT conversation is again one person and one lab. In a shared Project, each person talks to ChatGPT on their own and the others read along afterwards; every answer comes from OpenAI's models, so the second opinion is OpenAI checking OpenAI; and nothing records what the group decided, by whom, or why.
Bordet is built for the conversation a group chat was for. The people you invite and the models you seat (GPT next to Claude, Gemini and Grok, each with a role) are in one live thread, and the models read and challenge each other's replies. The room keeps one shared memory: a board with the objective, status and open questions, a decisions log you confirm, sources the whole table cites, and deliverables saved with versions. Your own ChatGPT can join as a seat through the connector and read the same memory.
| Capability | Bordet | ChatGPT |
|---|---|---|
| Several people in one live conversation | Yes: invite links, everyone in one thread, with the models | Group chats stopped 9 July 2026 (existing ones turning read-only) |
| Sharing context with colleagues | One room: the people, the models, the memory and the record together | Shared Projects: shared chats and files; each person talks to ChatGPT separately |
| Models from more than one lab in one thread | GPT-6.1 Sol, GPT-6 Astra, Claude Opus 5.5, Gemini 4 Argon, Grok 4.7 and more, side by side | OpenAI models only |
| Answers cross-examined by a different lab | Built in: members read and challenge each other, by role | No, one vendor's models |
| Memory | One project memory read by every model and every person in the room | Per account and per Project, read by ChatGPT only |
| A record of what was decided | Decisions log you lock in, plus a board of objective, status and open questions | No |
| Files and links as shared context | Sources: links, PDF and Word files, notes, cited by name by every member | Project files, read by ChatGPT |
| Deliverables kept with versions | Artifacts, revisable by asking their author | Canvas documents inside a chat |
| Use your own ChatGPT at the table | Yes, connect ChatGPT as a seat that reads the room and posts back | n/a |
| Pricing | Free to try, $1.50 starting credit, credits from $5, or your own keys; per-room spend caps | Free plan; paid plans up to $200 a month |

Yes. Bordet is a shared room where the people you invite and AI models from several labs (GPT, Claude, Gemini, Grok) work in one conversation, with a shared memory of the project and a decisions log. It is free to try, and a free account comes with $1.50 of credit.
OpenAI ran group chats as a pilot from November 2025 and began retiring them on 9 July 2026: no new group chats can be created, and existing ones are becoming read-only. Shared Projects remain, where colleagues share chats and files but each talks to ChatGPT separately.
Keep ChatGPT for everything personal. Use Bordet for the project several people work on, or where being wrong is expensive: a decision, a document going out under your name, a plan you will act on. There, one lab checking itself is the weak point. Bordet gives you GPT plus other labs arguing it out, your colleagues in the same thread, and a room that remembers the outcome. You can also connect your ChatGPT as a seat.
Yes. Bordet is model-agnostic: GPT-6.1 Sol, GPT-6 Astra and GPT-5.5 are in the catalog next to Claude Opus 5.5, Gemini 4 Argon, Grok 4.7, DeepSeek and Mistral (as of October 2026), and with a free account the model menu searches hundreds more on OpenRouter. Many rooms make GPT the Maker and let another lab play Critic.
ChatGPT's memory is good, and it is ChatGPT's. It is scoped to your account and to each Project, and only OpenAI's models read it. Bordet's memory belongs to the room: Claude knows what you told GPT on Tuesday, your co-founder sees the same board, and the decisions log is the same for everyone.
Open a boardroom, give each model a role, and watch the team remember what you decided.
