## FlexAI

FlexAI sits one layer above both model APIs and raw GPU clouds. Instead of stopping at a single inference call or a bare compute rental, it offers a managed path from the first API key to fully private AI infrastructure. Token Factory serves 30+ open models — text, code, vision, embeddings, image, speech and video — behind one OpenAI-compatible endpoint, so most applications migrate simply by changing a base URL. AgentOS adds an agent runtime connected to company context and tools, with scoped memory, approvals and an audit trail.

For teams that outgrow shared endpoints, FlexAI offers Dedicated GPUs for VMs, fine-tuning and production inference on FlexAI-operated NVIDIA, AMD and Tenstorrent fleets, plus AI Factory for VPC, on-premises and air-gapped deployments. The platform emphasises zero data retention: prompts and outputs are not stored and never train any model, alongside SOC 2 Type II and GDPR alignment and an EU data option.

Pricing is transparent and usage-based on the serverless lane — per token for text, and per image, per million characters of speech, per minute of audio or per minute of generated video for media models — while dedicated capacity and private deployments are quoted per engagement. A startup program offers credits and discounts on dedicated capacity.

**Pricing & Plans:** Pay-as-you-go serverless pricing (per token for text; per image, audio or video minute for media) with a free playground, plus dedicated GPU and private-cloud plans quoted on request. Startup credits and discounts available.

- **OpenAI-compatible model API:** One API key and a drop-in OpenAI SDK replacement unlock 30+ open models across text, reasoning, coding, vision, embeddings, speech-to-text, text-to-speech, image and video.
- **AgentOS agent runtime:** Run agents connected to company context and tools with scoped memory, tool permissions, human approvals and an auditable decision trail.
- **Dedicated GPUs and fine-tuning:** Reserve NVIDIA, AMD or Tenstorrent capacity for VMs, fine-tuning and production inference when shared serverless endpoints are not enough.
- **Private and sovereign deployment:** AI Factory supports VPC, on-premises and air-gapped installs, with zero data retention, an EU option, SOC 2 Type II and GDPR alignment.
- **No-signup playground:** Try image generation and chat completions directly in the browser before creating an account, on the same API you would use in production.

**Strengths:** Single OpenAI-compatible endpoint across text, vision, code, embeddings, speech, image and video models; Clear path from serverless inference to dedicated GPUs to private or air-gapped clouds; Zero data retention by default with SOC 2 Type II, GDPR alignment and an EU option; Governed agent runtime with approvals, audit trails and scoped memory

**Limitations:** Serverless rates are repriced against the market, so budgets need periodic review; Dedicated and private deployment pricing is quote-based rather than published; The broad catalogue means teams still need to benchmark model quality for their own tasks

## Stakpak

Stakpak is an open-source AI agent for running production infrastructure. Rather than a chatbot that suggests commands, it is a long-running process that lives on your own machines, watches your applications, and acts when something goes wrong. You install it as a single Rust binary, run stakpak init to let it discover your stack and generate an APPS.md manifest, then stakpak up and it runs in the background — scheduling checks, taking action and messaging you only when a human decision is genuinely required.

The scenarios it targets are the ones that ruin sleep: a health check fails at 3am, the agent finds 312 idle database connections, restarts the service, confirms latency dropped from 340ms to 12ms and posts a summary to Slack. Over longer horizons it runs a cost watchdog that spots idle RDS instances and orphaned EBS volumes and recovers real monthly spend, and it defuses time bombs like expiring TLS certificates, stale secrets and end-of-life runtimes.

The trust model is the differentiator. A coding agent that gets a command wrong produces a bad commit; an agent with production access that gets it wrong causes downtime or a five-figure bill. So Stakpak routes every network request — curl, Python, or MCP servers — through a Cedar-policy transparent proxy called Warden, detects and substitutes over 210 types of secrets before anything reaches a model provider, and keeps a full session audit log that lets you replay or roll back any change. It is Apache 2.0 licensed and written in Rust, and it is model-agnostic: use the unified LLM Gateway for one-wallet billing across Claude, GPT, Gemini and Mistral, or bring your own keys and run models locally.

**Pricing & Plans:** Open Source is free forever (Apache 2.0, bring your own keys). Hacker is $15/mo for 3 apps, Builder $45/mo for 10 apps, Team $450/mo for 50 apps with unlimited users, and Enterprise is custom. Extra apps cost $5/app/month and each paid tier bundles LLM Gateway credits.

- **24/7 auto-healing:** When a health check fails, the agent investigates — checking metrics, finding idle database connections, restarting the service, verifying the rollout — then posts a summary of what it did and how long it took.
- **Cloud cost watchdog:** Scheduled scans surface idle RDS instances and orphaned EBS volumes, quantify the waste in a report and can recover meaningful monthly spend before finance notices.
- **Expiry and drift defence:** Upcoming TLS expiries, stale secrets, deprecated APIs and end-of-life runtimes are caught and renewed ahead of time, with zero-downtime rollouts.
- **Single binary, runs on your machine:** A single Rust binary installs as a system service and persists across reboots, combining scheduling, messaging and a local API. It works with Claude, GPT, Gemini and Mistral, or your own model running locally.
- **Warden sandbox and audit logs:** Network requests go through a Cedar-policy sandbox, 210+ secret types are swapped for placeholders before reaching a model, and every command, edit and change is fully logged and replayable.
- **Slack, Telegram and Discord triggers:** Outcomes are reported to Slack, Telegram or Discord per agent, and only escalated to a human when the agent genuinely needs a decision.

**Strengths:** Genuinely open source (Apache 2.0) and runs entirely inside your own environment; Real production risk controls: Cedar network sandbox, secret substitution and replayable audit logs; One binary, no Kubernetes or control-plane sprawl to operate; Model-agnostic with a unified gateway or your own keys and local models

**Limitations:** Autopilot adds a long-running agent process with real production access, so misconfigured triggers carry real risk; Per-app subscription maths only makes sense once you manage several applications; Setup requires comfort with a terminal, system services and IaC concepts; The team is joining Vercel, so road-map and licensing direction may shift
