Vercel adds GLM 5.3 FlashX to AI Gateway

Vercel announced that Z.ai's GLM 5.3 FlashX is now available on Vercel AI Gateway, offering high-speed serving at roughly 200 tokens per second. The model retains the multimodal vision processing, tool-calling proficiency, and 1M token context window of GLM 5.3 Flash while reducing generation latency for interactive agent workflows.

// ANALYSIS

Throughput and latency have become just as critical as raw benchmark scores for agentic workflows where multi-step tool loops demand immediate feedback.

–**Accelerating Agent Loops:** Serving at ~200 TPS substantially compresses round-trip times in tool-heavy coding agents, making complex refactors and reasoning cycles feel responsive rather than sluggish.
–**No Compromise on Scale:** Combining high throughput with a 1M token context window allows agents to digest entire codebases and visual assets without truncation or throughput bottlenecks.
–**Zero-Friction Adoption:** With Vercel's zero-markup model and automated CLI setup for popular developer agents, switching to high-speed alternatives from proprietary frontier models is practically frictionless.

Inspo launches as an open-source Model Context Protocol server that gives AI coding agents access to real-world design systems and production website references to fix generic UI code generation.

Created by developer Hassan El Mghari (@Nutlope), Inspo is an open-source Model Context Protocol (MCP) server designed to overcome the "taste problem" in AI coding agents such as Claude Code, Cursor, Windsurf, and Zed. Instead of defaulting to generic dark-mode palettes and repetitive layouts, agents can query Inspo's curated archive of over 2,300 pages across 832+ production websites captured on desktop and mobile. The server extracts real design systems—including type ramps, color palettes, CSS variables, and spacing scales organized into structured DESIGN.md files—along with 68 canonical UI components featuring copy-pasteable JSX. Available via a single npx command and supporting both stdio and HTTP transports, Inspo enables AI agents to inspect proven production architectures and implement polished, context-appropriate user interfaces.

Interfaze hits Merge Gateway for deterministic OCR

Interfaze has launched on Merge Gateway, enabling developers to route workloads to its deterministic AI model designed specifically for document intelligence and structured data extraction. Unlike general-purpose conversational LLMs, Interfaze focuses on perception tasks where precision is critical, excelling at complex table parsing, audio understanding, and reliable data extraction from messy scans, invoices, and forms.

AgentCloak launches free AI prompt redaction extension

AgentCloak is a free browser extension designed to protect sensitive data when interacting with AI chatbots such as ChatGPT and Claude. Using an on-device neural model, the extension replaces detected PII with synthetic placeholders before sending prompts and automatically restores original values locally in the generated response.
