Claude Opus 5.5 hits Vercel AI Gateway

Vercel AI Gateway now offers Anthropic’s Claude Opus 5.5 for stronger agentic coding and knowledge work at lower cost than previous Opus versions. Fast mode adds a premium latency option for interactive workloads.

// ANALYSIS

This is a practical upgrade for developers building multi-step agents, though fast mode’s premium pricing makes workload selection critical.

–Faster output should benefit live debugging, interactive coding, and long tool-call chains.
–Lower standard costs could reduce the price of completed agent tasks, not just individual model calls.
–AI Gateway simplifies access, routing, billing, and provider management behind one integration.
–Fast mode is better suited to user-facing workflows than batch or background jobs.
–Developers should benchmark Opus 5.5 on real repositories before assuming vendor-reported gains transfer to production.

Mirage expands Tesseract with 250 video tools

Mirage has added over 250 free AI-native video tools to Tesseract, its video creative suite designed specifically for AI agents such as Astra and Opus 5.5. Rather than outputting flat renders, Tesseract equips agents with structured post-production primitives—including Boolean shape operations, custom WGSL shaders, animated morphing masks, and scene-wide adjustment layers—for non-destructive, fully editable video production.
