Apart from the database for record-like things (chats, emails, tables), vectors for larger things (such as web pages) are stored in serverless LanceDB on Wasabi, too.
Also Bifrost (https://github.com/maximhq/bifrost) as LLM gateway and Agentgateway (https://github.com/agentgateway/agentgateway) as MCP and OpenAPI/REST API gateway.

Postgres, pgBackRest, pgBouncer and another Go sidecar for pg (a la Pocketbase, but with Postgres backend), live in a single container managed by Horust.

Motivation: I have read quite a few stories about people's LLM API keys get uploaded verbatim in git repos, get stolen, or go unexpectedly over-budget. Being a panic-y person myself, I was thinking what we can do for those problems.
Before you read any further: only after I finished this whole thing, I found out that LiteLLM has this "virtual key" concept, and virtual key already comes with budget control. That actually implements the same thing as I did (with way more API endpoint support and other functionalities). So if you are already using LiteLLM or want to use LiteLLM, you can stop reading now and just use LiteLLM. However, LiteLLM has grown quite complicated: production deployment involves compute + database + secret manager, whereas my implementation is a serverless Cloudflare workers project, which can be hosted completely free (the free quota is more than enough at least for my personal use). If you are still interested, read on.
Solution: put real API key in an LLM API gateway, so your git repos/coding agents cannot even see the real API key. Instead, we create temporary, budget-scoped "tokens" in the LLM API gateway, and use coding agents with those tokens. The gateway will only let requests through and supply the real API key if the token has not expired, and has not exceeded its budget limit. This way, if our development machine is compromised, or coding agent gets into an infinite loop, our loss is limited (the token's budget limit) [1]. I mostly use DeepSeek/Claude for my side projects. Now everyday I create a new DeepSeek token with $1 budget and keep coding with the peace of mind knowing that I will only use (a bit more than) $1 for the day. Or before I hand off a complicated task to Claude, I will create a token with a fixed budget, and then sleep peacefully without worrying my API cost exploding.
Technical detail: the gateway splits response stream into two: one is forwarded to client directly, so clients still get streaming output like before; the other one is used to extract usage information from the response, calculate the cost, and update token budget.
Supported API endpoints: it works with official DeepSeek/OpenAI/Anthropic API endpoints. For coding agents (e.g. Codex, Claude Code, OpenCode), you will need to: point them to the gateway, create a new token in the gateway, and use your token as API key.
Compare with existing products:\n- LiteLLM: 1. This is a much smaller subset of what LiteLLM provides; this simplicity can let you easily audit the full source code. 2. Zero infra to operate: no VM to patch, no database server to maintain, no secret manager to set up; just upload worker code to Cloudflare. 3. Cloudflare provides sufficient free quota for personal use.\n- Cloudflare AI Gateway: Cloudflare AI gateway's budget control is static policies applied to a fixed time window (e.g. $1 every day). My implementation is more flexible: you can create a new budget limited token at any time, with any budget limit. My hope is that Cloudflare AI gateway just implements this, so I don't need to maintain my implementation :-)

Aerospace and defense is experiencing rapid growth. Unfortunately, most companies are struggling to use AI because of necessary data protections & compliance risk. These companies can move even faster if they could use the AI tools that most other industries take for granted.
I spent most of my career prior to Consus in aerospace & defense. I launched national security payloads at SpaceX, and was an early employee at Castelion. I\u2019ve watched first hand how compliance red-tape makes it difficult for companies to adopt new technologies and trust vendors that touch their sensitive data. For example, I worked with a satellite manufacturer that doesn\u2019t allow any AI tools, even for non-sensitive work.
Even as AI has become extremely useful over the past 9-12 months, I was surprised by how many aerospace & defense companies refused to touch it. They could see how it could be helpful, but they were scared about model providers training on their data, violating an ITAR rule, or risk losing new business because of a failed cyber assessment. These are all rational fears.
There were a lot of ways to solve some/all of these problems, but we focused on building a compliant AI inference layer that can "plug" into any AI tool or workflow. Just as OpenRouter integrates with most tools, Consus can connect to tools like ChatGPT or Claude, open source tools including the Pi coding agent or Open WebUI, or integrate with applications built and maintained by individual organizations.
Almost no aerospace & defense company lives in all three major GovClouds (AWS, Azure, Google). When I mapped where frontier models can legally run for ITAR and CUI work, each provider had some subset of models, and each model achieved varying levels of compliance. Our customers don\u2019t think in terms of cloud providers. They think about the data controls they require, and the model they want to use.\nThat is why we built the compliance suffix. Under the hood, every request hits a single OpenAI-compatible endpoint, where keys are verified and policy is enforced before anything touches inference. Every model name must carry a compliance suffix, such as gpt-5.6-sol:fedramp-high or claude-opus-5-5:itar, and any bare model name is rejected. We never proxy to the standard commercial endpoints.
Our customers are also able to build an allowlist of models, and assign spend & model restrictions to individual users in the organization. This is all handled through our Consus Portal where teams can manage spend, keys, and policies.
A typical question we hear is why not just use Bedrock in AWS GovCloud or Azure Government directly. For small teams, just getting access to these platforms is difficult. For larger organizations, GovCloud lets you inherit some but not all of the controls needed to handle sensitive data. Also, models are split across providers: GPT-5.6 Sol is only available in Azure Government, while Claude Opus 5.5 is served through Bedrock in AWS GovCloud. If you want both, you are standing up and securing two separate government cloud environments. We run all of them behind one endpoint so customers don\u2019t have to pick a cloud, and we handle the compliance work for each one.
Given the data sensitivities, Consus does not store any customer data at rest. All prompts and completions stay in memory only for the length of the request and are never logged or written to disk. Zero data retention is strictly enforced both on ourselves and the infrastructure/model providers. We do keep metadata on each request and response for billing and audit purposes.
Consus is not self-serve by design. ITAR requires us to know exactly who is on the other end of every key, so we verify every organization and put a contract in place before issuing API keys. We charge our customers a compliance fee starting at $40/mo/seat plus AI tokens at cost.
We are actively serving customers, and would love any feedback from security experts, or developers/engineers working in highly regulated industries!

I\u2019ve been building Relay, a self-hostable AI gateway. The main thing I wanted to solve was smart routing without turning the gateway itself into a bottleneck. Relay can classify an incoming request, decide what kind of model capabilities the request needs, then route it across your configured providers while also accounting for limits and available capacity. It ships with routing classification models I\u2019ve trained specifically for this problem, with the option of swapping that piece for Laya or other System One models.
This started when I was trying to string together several providers\u2019 free tiers. I kept hitting rate limits at different intervals, which broke some of my agent clients. Some agents were also getting greedy with shared resources, so I needed a way to manage how they used the available capacity.
That led to Relay\u2019s queue-first approach. Sometimes it\u2019s better to wait a second or two for your preferred model than immediately fall back to another one. Relay queues and paces requests against configured provider limits, aiming to make use of available capacity without repeatedly hitting rate-limit errors or needlessly falling back to worse models.
Relay\u2019s classification model also looks for signals that a request needs specific capabilities, such as coding or more complex reasoning, while classifying the request\u2019s main intent before routing anything.
One thing I\u2019ve obsessed over is keeping that decision layer cheap. Relay\u2019s built-in classifier runs in the single digit millisecond range. It has a deliberately narrow job: classifying LLM requests and helping decide where to send them. It probably won\u2019t be playing DOOM, but that\u2019s a trade off I\u2019m happy with for a routing layer. In the routing tests I've run so far, the built-in classifier is considerably faster than Laya while producing broadly similar routing decisions. Working on getting Jev up and running, and will report back to see how that stacks up as well.
The community version is available now, with a public repo, a built-in dashboard, and a local classifier.

I\u2019ve been building Relay, a self-hostable AI gateway. The main thing I wanted to solve was smart routing without turning the gateway itself into a bottleneck. Relay can classify an incoming request, decide what kind of model capabilities the request needs, then route it across your configured providers while also accounting for limits and available capacity. It ships with routing classification models I\u2019ve trained specifically for this problem, with the option of swapping that piece for Laya or other System One models.
This started when I was trying to string together several providers\u2019 free tiers. I kept hitting rate limits at different intervals, which broke some of my agent clients. Some agents were also getting greedy with shared resources, so I needed a way to manage how they used the available capacity.
That led to Relay\u2019s queue-first approach. Sometimes it\u2019s better to wait a second or two for your preferred model than immediately fall back to another one. Relay queues and paces requests against configured provider limits, aiming to make use of available capacity without repeatedly hitting rate-limit errors or needlessly falling back to worse models.
Relay\u2019s classification model also looks for signals that a request needs specific capabilities, such as coding or more complex reasoning, while classifying the request\u2019s main intent before routing anything.
One thing I\u2019ve obsessed over is keeping that decision layer cheap. Relay\u2019s built-in classifier runs in the single digit millisecond range. It has a deliberately narrow job: classifying LLM requests and helping decide where to send them. It probably won\u2019t be playing DOOM, but that\u2019s a trade off I\u2019m happy with for a routing layer. In the routing tests I've run so far, the built-in classifier is considerably faster than Laya while producing broadly similar routing decisions. Working on getting Jev up and running, and will report back to see how that stacks up as well.
The community version is available now, with a public repo, a built-in dashboard, and a local classifier. It\u2019s written in Go, and you can run it with npx @anchorshell/relay or build it from source. The gateway itself is lightweight; it also ships with small classification models you can use locally.

I\u2019ve been experimenting with LLM agents for a while and often felt that\nfor simple workflows (chat, tool calls, small loops), existing\nframeworks add a lot of abstraction and boilerplate.
So I built a small Python library called PicoFlow. The goal is simple:
express agent workflows using normal async Python, not\nframework-specific graphs or chains.
Minimal chat agent
Each step is just an async function, and workflows are composed with >>:
from picoflow import flow, llm, create_agent\n\n LLM_URL =\n \u201cllm+openai://api.openai.com/v1/chat/completions?model=gpt-4.1-mini&api_key_env=OPENAI_API_KEY\u201d\n\n @flow\n async def input_step(ctx):\n return ctx.with_input(input(\u201cYou:\u201d))\n\n agent = create_agent(\n input_step >>\n llm(\u201cAnswer the user: {input}\u201d, llm_adapter=LLM_URL)\n )\n\n agent.run()\nControl flow is just Python
Loops and branching are written with normal Python logic, not DSL nodes:
def repeat(step):\n async def run(ctx):\n while not ctx.done:\n ctx = await step.acall(ctx)\n return ctx\n return Flow(run)\nSwitching model providers = change the URL
Another design choice: model backends are configured via a single LLM\nURL.

PicoFlow is probably useful if you:
- want to prototype agents quickly\n- prefer explicit control flow\n- don\u2019t want to learn a large framework abstraction
It\u2019s probably not ideal if you:
- rely heavily on prebuilt components and integrations\n- want a batteries-included orchestration platform
