A 3D world from a single prompt: Opus 5.5 built 1906 San Francisco
On September 22, Alex Albert recreated a historical scene of 1906 San Francisco in Blender with a single prompt using Opus 5.5.

I got hooked on Blender with Opus 5.5. The model handles 3D modeling and images better, so you can build an entire world with a single prompt. Historically accurate Market Street in San Francisco in 1906, before the earthquake.

Blender has no built-in connection to an LLM. The official Blender MCP Server gives Claude natural-language access to the Blender Python API: it analyzes and debugs scenes, writes batch scripts, and adds tools to the interface. It requires Blender 5.1+, the add-on, an LLM client, and the MCP Server.
The connection is already available. The add-on is installed by dragging the link from the Blender MCP Server page into Blender twice: first to add the Blender Lab repository, then to install the add-on itself. You can also download the ZIP and choose Install from Disk. For clients with .mcpb, Blender offers a ready-made MCP Bundle; everyone else needs to build the server following the setup instructions. For sensitive data, Blender recommends a VM or a separate machine.
Anthropic released Opus 5.5 on September 22 and said it is 40% cheaper than Opus 5 on typical tasks. In the API, input tokens cost $4 per million, output tokens $20, cache reads $0.20, and cache writes $5. Fast mode runs up to 2.5 times faster and costs $8 and $40 per million tokens.
On CursorBench 4.0, Opus 5.5 scored 57.8% in max effort mode versus 46.6% for Opus 5. On Chartography, the result rose from 83.4% to 89.0%.
Opus 5.5 is now available in the API and on Claude Pro, Max, Team, and Enterprise plans.
