Claude Opus 4.5 Is Here | Databricks Blog
November 24, 2025 - Data has to be exported to external APIs, stitched back together, and managed across separate tools. This creates governance risks, breaks lineage, and slows adoption. That is why we introduced AI Functions, a simple way to apply LLMs directly to governed enterprise data. Instead of moving data out of secure systems, Databricks brings AI models to your data so you can extend existing data pipelines with AI while preserving governance, lineage, and observability.

2 weeks ago - If/when Opus 4.5 ships, expect incremental but meaningful gains over Opus 4.1 in reasoning, coding reliability, and agent stability; expect pricing to stay within Opus’ premium slab (with similar input/output pricing and enterprise tiering), and expect the model to remain a high-investment choice for heavy output workloads.

Claude Opus 4.5 is a step forward in what AI systems can do, and a preview of changes in how work gets done.
It’s the best model in the world for coding, agents, and computer use. It’s also meaningfully better at everyday tasks like working with slides and spreadsheets. When we gave it our two-hour engineering assignment, it finished faster than any human ever has.
Claude Opus 4.5 is available today on our API and on all three major cloud platforms.

I am very happy to be positive about this, it does feel as though they may have listened to a lot of the complaints about the model. HOWEVER: on loading CC, I see: To give you room to try out our new model, we've updated usage limits for Claude Code users Emphasis mine - And the pessimist in me says "this is literally just to build hype and will be reduced swiftly" So I wouldn't get too happy about the limits, but the API cost reduction could signify this change may be permanent? Either way, best to enjoy the model for now. Looks like Claude is back on top (for coding, Gemini is still SOTA for overall reasoning) EDIT: So it seems like Pro users don't get Opus still in Claude Code. So I am firmly back down on the hype train. What a bitch move
