AccInt vs FastLLM

AccInt (Accreted Intelligence) is a local "Work Model" for AI coding agents. It sits underneath the agent you already use, such as Claude Code, Codex, OpenCode or Cursor, and keeps an accountable record of the agent's work on hardware you control.

AccInt tracks open promises (what the agent said it would do), evidence, approval gates and outcome credit, and turns successful runs into reusable runtimes, so the same kind of task gets better and cheaper each time it runs. When someone asks "why did the agent do that?", the reasoning and evidence are already written down. It needs no account and no API key, and everything stays on your machine.

Good fit if you: run AI coding agents on repeated…

FastLLM is an AI API gateway: a single endpoint and dashboard for accessing several large language models. Its site runs on the open-source New API gateway software, which offers OpenAI-compatible endpoints, per-key usage limits and a central admin dashboard for tracking consumption.

The idea is to let developers use different models through one key and one billing account instead of managing a separate account for each provider. Usage is tracked per key, so teams can share access while keeping an eye on spend.

Good fit if you: want one OpenAI-compatible endpoint for several models and simple usage tracking.
Less ideal if you: need enterprise contracts, data-processing agreements or guaran…
