AI21 Labs Introduces Maestro to Optimize AI Model Selection
By
–
Routing every task to your largest model burns tokens, adds latency, and inflates costs. @AI21Labs' Maestro Orchestration Meta Model (OMM) is the layer above your stack that dynamically selects the right model or tool for each step, optimizing cost, latency, and value automatically. ai21.com/?utm_source=org-twi… [Translated from EN to English]

Production AI Agents Need Search, Branching, and Path Pruning
By
–
Most agents guess the next move. They don't search. Production systems need to branch, route, and kill bad paths before they compound. These gaps are where most teams quietly lose. We mapped them in the article below. 👇 ai21.com/blog/mind-the-gap/?…

Stop Overpaying for AI Inference: Routing Solutions Matter
By
–
You're overpaying for inference. SWE-bench shows cheaper models solve the same easy problems as frontier ones. The issue isn't model quality. It's that most systems don't route at all. We broke down the 4 gaps breaking production AI systems: ai21.com/blog/mind-the-gap/?…

Silent 32-bit Integer Overflow in vLLM Mamba-1 CUDA Kernel
By
–
3/4 Root cause: a silent 32-bit integer overflow inside a vLLM CUDA kernel for Mamba-1 selective scan forward kernel. cache_index * ssm_states_batch_stride overflowed once cache slots got large enough, corrupting writes with no crash and no warning.

Integer Overflow Bug Fix in vLLM: uint32_t to size_t
By

4/4 The fix upstream? Two characters, basically:uint32_t → size_t Weeks of debugging for one tiny type-width bug. Great reminder that in RL infra, the hardest part is often finding the right boundary around the failure. 👉Blog with the full investigation + the upstream vLLM PR: ai21.com/blog/vllm-cuda-inte…
