Aleph Alpha releases Kolibri 78B open-weight German-English MoE model

Aleph Alpha released (Oct 3, German Unity Day) Kolibri—an Apache 2.0 open-weight English–German Mixture-of-Experts transformer with 78.1B total / ~3.46B active parameters, up to 1M-token context (recommend ≤262k for serving), reasoning effort modes (none/low/medium/high), and tool calling—aimed at sovereign on-prem deployments for public administration, industrials, and aerospace. Weights on Hugging Face as `Aleph-Alpha/Kolibri-1` (~78 GB FP8; min ~2× A100 80GB) with `aleph-alpha-inference` vLLM plugin; trained ~24T tokens (20T pre-train on 768 B200s over 21 days; ~21% German) under EU AI Act / GPAI Code of Practice framing, with Merlin-Arthur grounding/abstention. Company claims Pareto quality-vs-serving-cost leadership among compared open models and strong AIME/GPQA/LiveCodeBench numbers (self-reported). Distinct from Kolibri Origin (internal 30B pipeline validation) and from prior European open-weight cards.

Google Antigravity adds Claude Opus 5.5 and Sonnet 5.5 for paid plans

Google Antigravity’s official models docs now list (Oct 3) Claude Opus 5.5 (thinking) and Claude Sonnet 5.5 (thinking) as selectable reasoning models for Google AI Ultra and non-trial Google AI Pro subscribers—no separate Anthropic API key required. Free, Google AI Plus, Enterprise, and Pro free-trial accounts are excluded. Claude Opus 4.6, Claude Sonnet 4.6, and GPT-OSS-120B are marked for removal on Nov 2, 2026, so free/Plus users will lose Claude options once those retire. Distinct from the Sept Anthropic Claude Opus/Sonnet 5.5 model launches, from Antigravity SDK local Gemma offline support, and from Gemini 4 Argon Fairwind-only access.

OpenAI safety leader David Robinson resigns, citing broken culture

David Robinson, a ~3.5-year OpenAI safety employee who led safety reports for major product launches, resigned (Oct 3) and published an Atlantic essay arguing OpenAI’s “culture is broken,” that iterative deployment “guarantees periodic failures” at growing scale, and that frontier labs should run more like nuclear plants/airports with redundancy and outside safety incentives—citing Hugging Face agent breakouts and further rogue-agent discoveries. OpenAI spokesperson Drew Pusateri said the company pauses/holds models when needed, is hardening research/test security, training for responsible task completion, expanding third-party evaluators, and improving real-time monitoring. Distinct from Jacob Coxon’s Anthropic resignation, Lilian Weng departures, and the Oct 1 three-researcher parting.
