Competitive Brief: Call Sheet

Researched: OpenAI · for Mistral reps

Focus: enterprise and sovereign AI for developers and agents

Today's angle

OpenAI released GPT-6.1 Sol at DevDay on September 29, 2026, an upgrade to GPT-6 Sol that it says nearly matches its GPT-6 Astra flagship on agentic coding, computer use and professional work at one fifth of Astra's standard token prices. In the API it lists at $2 per million input tokens and $10 per million output tokens, with cached input at $0.10 per million. It is available now in ChatGPT Work, Codex and the API as gpt-6.1-sol, though not yet in the main ChatGPT chat.

Objection handling

"Isn't OpenAI the safe default everyone already uses?"

Counter: three halts to OpenAI's frontier plans in three months, the latest days before its own developer conference. Open weights let you keep the version you validated, air-gapped inside your own walls, on your own timeline.

"Mistral's models aren't as good as GPT-6 Astra."

Counter: Move the evaluation to the buyer's deployment constraints and running cost, where our edge is structural: private repos with no call home, running on hardware they already own.

"Mistral is small. Will you even be around in three years?"

Counter: Point to the closed, Samsung-led €21 billion round, Microsoft's multibillion dollar bet and five named enterprises locked into no-early-exit, five-year commitments funding the compute buildout, then close on the fact that Apache 2.0 weights mean your production system never depends on our uptime.

"Your ecosystem is smaller, with fewer integrations and guides."

Counter: Ask the buyer which platforms their workflow runs on, then map Vibe's connectors and Mistral's Microsoft Foundry, Copilot Studio and Azure Local availability against that list on the call.
