E2B Infrastructure is the open-source cloud infrastructure that runs E2B’s AI code-interpreting environments and agents. Developers can deploy it with Terraform on GCP or AWS, including for self-hosting.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02510 | $0.02510 |
| Opus 5.5 | $0.01004 | $0.01004 |
| Sonnet 5.5 | $0.00502 | $0.00502 |
| Haiku 4.5 | $0.00251 | $0.00251 |
Grade A, and why
infra CLAUDE.md scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview
E2B Infrastructure is the backend infrastructure powering E2B (e2b.dev), an open-source cloud platform for AI code interpreting. It provides sandboxed execution environments using Firecracker microVMs, deployed on GCP using Terraform and Nomad.
Start with docs/ARCHITECTURE.md — it explains what each service does, how services interact (with diagrams of the core flows: sandbox creation, traffic routing, pause/resume, template builds), and the deployment topology. Reading it first is the fastest way to understand this repository.
Keep docs/ARCHITECTURE.md updated: if your change alters anything it describes (service responsibilities, ports, protocols, data stores, flows, deployment topology), update the document in the same change.

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.

infra CLAUDE.md is an instructions file published in the GitHub repository e2b-dev/infra (1,738 stars, last pushed 11d ago), licensed Apache-2.0. It adds 2,510 tokens to every session, about $0.0100 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
