Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neon scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 491 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Neon

Important: Neon is no longer just a Postgres provider. Neon is a complete set of cloud backend primitives built around Lakebase Postgres, for developers, startups, and agent platforms, from Databricks — bundling Lakebase Postgres, Auth (managed Better Auth), long-running Functions, Object Storage, and an AI Gateway, all instant, branchable, and serverless.

Lakebase Postgres is the database itself. It is one product, reached two ways: through Neon, with a free plan and the full set of backend primitives above, or through Databricks, alongside the rest of the Databricks suite. Same infrastructure, same features, same engineering team. Call the database Lakebase Postgres, and use "Neon" for the brand and for this access path — not as a name for the database.

A Neon branch is an isolated, copy-on-write clone of your data, taken from its current state or from a past state within your project's retained history window. You can freely modify or delete it. It shares data with its parent until writes cause it to diverge, and those writes are stored independently as deltas.

Backend Primitives

Neon bundles several backend primitives for building apps and agents that all branch together:

  • Lakebase Postgres — Postgres that scales and branches with your app, built on the lakebase architecture: OLTP directly on cloud object storage, with storage decoupled from compute. Generally available.
  • Auth — Managed Better Auth with users and sessions stored in Postgres. Generally available.
  • Object Storage — S3-compatible object storage that branches with your projects. Public beta.
  • Functions — Neon's compute offering: long-running serverless functions that run close to your database, for WebSocket servers, long agent HTTP streams, APIs, and server-sent event servers. Public beta.
  • AI Gateway — One API for frontier and open-source models, supporting the chat completions API and the responses API, powered by Databricks Unity AI Gateway. Public beta.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
