OpenAI Cuts Cursor Off After the SpaceX Buyout

Direct model access ends November 12, leaving the developers who rely on OpenAI models inside Cursor to find another route.

OpenAI is ending its partnership with Cursor following the editor's acquisition by SpaceX, cutting off direct access to its models on November 12. In a note posted Thursday, the company said it could no longer trust that a SpaceX-owned Cursor would use its technology within the terms of service — an implicit accusation that frontier weights might be distilled by a rival.

The move lands hardest on the developers who treat Cursor as their default interface to GPT-class models. Within hours, the ecosystem began routing around the rupture: Anthropic's chief compute officer reaffirmed its support for Claude inside Cursor, while Replit offered free OpenAI-model access as an independent, multi-model alternative and pledged to fund business transitions off the platform.

Tencent's MIX-STQ1_0 compression takes Hy4-preview from 1.5TB to roughly 200GiB of GGUF.

Hunyuan Hy4 Squeezed to 200GB — and It Still Works

The trick isn't just going low; it's deciding where, as calibration data picks each layer's bit width.

Tencent compressed its Hy4-preview model from 1.5 terabytes down to about 200GiB in GGUF format, and reports it still performs well. The new MIX-STQ1_0 scheme uses calibration data to select a per-layer bit width: some layers drop as low as 1.31-bit STQ1_0, while others rise to 2.06-bit IQ2_XXS — all within the same memory budget.

Watching a popular coding tool lose frontier-model access shows why model resiliency matters: in the future, products will keep working even when several underlying models go offline — they'll just route around them.
