Google releases Gemma 4; Hermes Agent adoption surges
Google (DeepMind) released Gemma 4 under an Apache 2.0 license as an open multimodal model family (text, vision, audio) with multiple sizes (E2B, E4B, 26B A4B MoE, 31B) and very long context support (up to 128K/256K reported). Day‑one ecosystem support was broad: vLLM, llama.cpp, Ollama, Unsloth, Hugging Face Inference Endpoints, Intel hardware and Google AI Studio. Community benchmarks showed local inference on consumer hardware (RTX 4090, Mac mini M4, iPhone) with varied tradeoffs in speed, KV cache and memory. Separately, Hermes Agent (an open harness) saw rapid user migration driven by improved memory/plugin architecture and pluggable memory providers (Honcho, mem0, Hindsight, RetainDB, Byterover, OpenVikingAI, Vectorize-style backends). The newsletter also flags research signals (Anthropic’s reported 171 emotion-like vectors in Claude), STT news (Microsoft MAI-Transcribe-1 preview via Azure), and real-world deployments (Baseten and OpenEvidence).
A major platform (Google/DeepMind) released an Apache‑licensed, high‑capability open model (Gemma 4) with day‑one ecosystem support — this materially affects model accessibility, local/edge inference, agent development and competitive benchmarking across the AI stack.

Key Takeaways & Evidence Grounding
- Google released Gemma 4 under an Apache 2.0 license as an open multimodal model family (E2B, E4B, 26B A4B MoE, 31B) with extended context windows (up to ~256K reported).
- Day‑0 ecosystem support for Gemma 4 included vLLM, llama.cpp, Ollama, Unsloth, Hugging Face Inference Endpoints and Google AI Studio; Intel hardware support was also noted.
- Local inference benchmarks reported: 162 tok/s decode and 262K native context on a single RTX 4090 for the 26B A4B (reported by @basecampbernie); TurboQuant KV cache reductions (13.3 GB → 4.9 GB at 128K context) were shown for the 31B model (reported by @Prince_Canuma).
- Hermes Agent saw rapid adoption as an open agent harness; Teknium/Nous reworked Hermes’ memory system to support pluggable providers (Honcho, mem0, Hindsight, RetainDB, Byterover, OpenVikingAI, Vectorize-style backends).
- Anthropic research reported identification of ~171 emotion‑like activation vectors inside Claude, raising interpretability and alignment discussions.

Google DeepMind launches Gemma 4 multimodal models
Google DeepMind released Gemma 4, a family of open-weight multimodal models distributed under an Apache 2.0 license. Gemma 4 includes multiple sizes — notably a 31B dense model, a 26B MoE variant (“A4B”, ~4B active), and two edge-focused effective models (E4B, E2B) with native text, vision and audio inputs — and supports very long contexts (up to 256K tokens for large models). Early community benchmarks and leaderboards report strong reasoning and token-efficiency signals for the 31B variant, and Day‑0 ecosystem support appeared across local and serving stacks (llama.cpp, Ollama, vLLM, LM Studio, transformers.js). The release emphasizes on-device/edge deployment, agent workflows and structured outputs (function-calling/JSON). Reported architectural notes include MoE blocks, per-layer embeddings, KV-cache sharing and proportional RoPE, though some analyses attribute the gains largely to training recipe and data improvements.
Gemma 4 Enables Agentic AI on Consumer Devices
This recap of The Agent Factory episode with Omar Sanseviero (Google DeepMind) reviews the release and capabilities of Gemma 4, an open model family optimized for on-device and local deployment. Since launching last month, Gemma 4 has recorded over 50 million downloads. The family includes small edge-optimized variants (E2B & E4B), a 31B dense model, and a 26B Mixture-of-Experts (MoE) model. Google DeepMind moved Gemma 4 to an Apache 2 license to enable commercial use and local fine-tuning in regulated or air-gapped environments. Demonstrations highlighted offline agentic workflows (local food-tour agent, Android skill selection), autonomous Python execution including a physics simulation, and architecture choices such as per-layer embeddings and variable-aspect-ratio vision support.
Gemma 4 Surpasses 2 Million Downloads
Gemma 4 reached roughly 2 million downloads within its first week, driven by rapid local deployments, positive reviews, and visible on-device demos. The release has become a prominent open-model reference for edge inference, Apple Silicon tooling, and low-friction local deployment, with users running Gemma 4 on consumer Apple hardware and Hugging Face activity showing strong trending. Red Hat published quantized Gemma 4 31B model cards, and vendors like Ollama made the model available on cloud GPU backends. Separately, Nous Research’s Hermes Agent drew attention for a self-improving agent loop and persistent-memory approach, while broader industry threads covered specialized small models, RL and routing research, and strategic/commercial moves by frontier labs (OpenAI, Anthropic) related to governance, compute capacity, and monetization.
