1The coolest use for the Vision Pro
- A programmer building their first home discovered an innovative use for Apple Vision Pro to visualize floor plans in virtual reality. They created 3D models from 2D floor plans using Fusion 360, added IKEA furniture models and textures for scale, then developed a custom VR app called "Prospector" with controller support and flight controls. This allowed them to walk through and evaluate their future home's layout and spatial relationships before construction, making the abstract floor plans feel tangible and helping with design decisions in the expensive housing market.

5Kimi K3-256k
- Kimi Code offers four models: K3 (1M context), K3-256k (256k context), K2.7 Code, and K2.7 Code HighSpeed. K3-256k is recommended for daily coding tasks as it uses half the quota of K3 while delivering same results within 256k context. Different membership plans unlock different models and features, with higher tiers getting access to 1M context and HighSpeed versions.
Pricing and context window strategy
Discussion centers on Kimi's tiered pricing model offering a 256k context version at half the price of the 1M version. Users debate whether 256k is sufficient for most tasks, with some finding it adequate while others prefer larger contexts for complex projects. The ability to seamlessly switch between models without cache invalidation is highlighted as a key advantage.Infrastructure and technical implementation
Conversation focuses on whether the 256k version is just an API limitation or a separate model, the technical aspects of context window management, and memory requirements for KV cache. Users discuss quantization, VRAM needs (1.5TB for full model), and how different context sizes affect computational costs and serving infrastructure.Model availability and competitive landscape
Users discuss Kimi's waitlist due to overwhelming demand and hardware constraints, comparing it favorably to Anthropic's service disruptions. The conversation touches on open-weight model accessibility through third-party providers, concerns about potential quantization by resellers, and how Chinese AI companies are challenging established players despite export restrictions.
