Ollama

TL;DR I put a LiteLLM proxy gateway in front of every LLM I use — local Ollama models for bulk/cheap classification work, OpenRouter for frontier models when I need them, plus cloud vendors if needed. Every app and agent targets one OpenAI-compatible endpoint. Per-key budgets and daily spend alerts make runaway costs impossible. I define model-to-backend mappings in YAML, let LiteLLM handle the routing, and route based on intent: ask for solar-expert when I need a domain-specific Q&A bot backed by a small local model, ask for claude-opus-4-8 when I need real reasoning. The gateway cost? ~50ms latency overhead and one Kubernetes Deployment. The gain? No more vendor SDK sprawl, no more guessing which model is wired into a cron job, and spend visibility that I actually trust. ...

TL;DR Last time I wrote about giving my Ultima Online shard’s NPCs a voice, a memory, and a small autonomous life. That post ended with “the peasant talks back now.” In the eight days since, the project grew six new systems: NPCs keep daily routines anchored to real places, every town runs a rumor board that traveling NPCs physically carry between cities, townsfolk gossip about players (your katana, your karma, your reputation), the GM avatar got actual powers governed by a genie rule, villagers hand out delivery quests, and a population director keeps every city stocked with 200 ambient “denizens” who hail you in the street. That’s ~3,200 new NPCs and maybe a dozen new LLM call sites, still running entirely on a local gemma-class model — the trick is that the model never gained a single new permission. Every new capability is deterministic code; the LLM still only ever produces words and picks verbs off allowlists. Also: I found out my RAG pipeline had been silently dead for days, and the lesson there is worth the price of admission. ...

TL;DR A Mac Studio M3 Ultra costs the same as a single 4090 but comes with 256 GB of unified memory and 60-core GPU, all running at 100–200 W under inference. I stopped trying to pass MPS into containers and instead run Ollama and ComfyUI natively on macOS, then proxy them back into k3s as simple Kubernetes Services with manual Endpoints. Two Mac Studios connected via Thunderbolt 5 split the load: one handles hot-path LLM inference and embeddings, the other runs the heavy forge for diffusion and long-horizon reasoning. Both are cheaper to run than a single-socket A100 and require no special driver stacks. ...

TL;DR I run an Ultima Online shard on my homelab where the NPCs are driven by a local LLM instead of canned dialog trees. Each NPC rolls a persisted identity, remembers conversations with individual players across reboots, runs its own errands and cross-map journeys, and — the part I’m writing about today — strikes up ambient chatter with nearby NPCs on its own. The newest work extends all of that from townsfolk to language-speaking monsters: ogres, lizardmen, ratmen, gargoyles, daemons, and especially liches, who address each other like god-kings deigning to notice an insect. Inference is a local gemma-class model behind an in-cluster gateway, so it’s free and private, with the one tradeoff being cold-load latency. It’s single-shard hobby-scale and it absolutely shows the seams. I love it. ...

TL;DR I open-sourced the integration that puts a local LLM behind the NPCs on my Ultima Online (ServUO) shard. It’s about 7,500 lines of C# that drop into a shard’s Scripts/Custom/ directory and compile at boot — no separate build, no service to deploy. This post is the code-level companion to the story version of the project: how config hot-reloads, how the model client marshals async results back onto the game thread, how the LLM is kept entirely out of the simulation loop, and how a deterministic allowlist makes a non-deterministic model safe to put in a stateful world. The whole thing is fail-open: if the model is slow, down, or wrong, the NPC silently degrades to a vanilla ServUO NPC. Code is on GitHub: ZoltyMat/uo-llm-npc. ...

TL;DR A new Opus model shipped, so I sat down to re-tune the agent harness I drive it with — the CLAUDE.md files, skills, hooks, and settings that shape every session. The surprising part: the most valuable changes weren’t trimming prompts for the smarter model. They were wiring the agent into infrastructure I already run — offloading bulk work to a local LLM (≈$0), a live homelab statusline, session tracing for an “action audit,” and a goal-drift monitor that uses the local model as judge. I also learned not to trust the new model’s own suggestions about what to cut. It wanted to delete load-bearing guardrails. ...

TL;DR You have a 24GB VRAM GPU. You want a private, self-hosted AI assistant that rivals ChatGPT – no subscriptions, no data leaving your machine. This guide walks you through setting up Ollama (local model runtime) and OpenClaw (AI gateway with a web UI) on Windows using Docker Desktop. But the real value here is the model recommendations. I ran 5,475 evaluations across 21 prompt variants and 6 models on real trading data. The results contradicted almost everything the community recommends. Finance-tuned models performed worse than a coin flip. Chain-of-thought reasoning models were anti-patterns. The winners were general-purpose MoE (Mixture-of-Experts) models that nobody talks about for specialized tasks. ...

TL;DR My Mac Studio M3 Ultra runs Ollama with 70B+ models but isn’t a k3s node. I needed it to show up in Grafana next to the cluster workloads. The solution: node_exporter for system metrics, a Go reverse proxy for per-model inference metrics, a custom Python exporter for model inventory and VRAM tracking, and Grafana Alloy for shipping logs to Loki. All four services managed by Ansible, all metrics scraped by the cluster’s Prometheus. ...
