Blackbox AI
Blackbox AI Technologies · Enterprise-Only AI Coding and Inference Platform
Blackbox AI is not free: it has no free plan, free trial, or self-serve subscription, and it is moving to enterprise-only access. Companies buy a custom annual commitment for its zero-data-retention router across 300+ models, dedicated inference, cloud coding agents, and CLI.
Best for
Engineering organisations that want secure, governed access to 300+ models, dedicated inference, and coding agents under one enterprise contract
Not ideal for
Anyone looking for a free or self-serve coding assistant: there is no free plan, free trial, or individual subscription, and access is sold through enterprise sales
Who it's for
Engineering and platform teams at companies that need secure model access, dedicated inference, and coding agents
Capabilities
- Blackbox Router: 300+ open and closed models through one OpenAI-compatible endpoint
- Agents API: run cloud coding agents on repositories and turn successful runs into pull requests
- Remote Agent cloud sandboxes, with dedicated runners and SSO on Enterprise
- Agentic CLI with plan mode, headless mode for CI pipelines, and MCP, hooks, and AGENTS.md support
- Multi-agent mode: send one task to Blackbox, Claude Code, Codex, and Gemini, then let a 'Chairman' model rank the results
- Dedicated single-tenant inference deployments
- End-to-end encrypted inference, contractual zero data retention, and PII removal before closed models
- SAML SSO, SCIM, RBAC, audit logs, and data residency
Limitations
- No free plan, published free trial, or self-serve subscription; access starts with sales and an annual committed spend
- Unused committed spend expires at the end of the billing period
- Costs depend on model mix and volume, since the commit is drawn down at per-token rates
- The VS Code extensions have been unpublished, and IDE extensions are no longer part of the published product line
- Generated code still requires review before production use
Use cases
- Giving an engineering organisation governed access to many models through one endpoint
- Running cloud coding agents that work on repositories and open pull requests
- Deploying dedicated, single-tenant inference with zero data retention
- Running agentic coding tasks from the terminal or inside CI pipelines with the Blackbox CLI
Our take
Blackbox has moved from a coding assistant with free basic use to an enterprise-only platform, and the entry should be read that way. Its strongest pitch is governed access: one endpoint for hundreds of models, dedicated inference, and contractual zero data retention, plus coding agents that can open pull requests. For organisations that want that combination under one contract, it is a credible option. For individual developers who remember the free web assistant or the VS Code extension, it is no longer an option. GitHub Copilot's free tier, Cline, or Kilo Code fill that role, and Cursor or Claude Code suit developers willing to pay for a self-serve plan.
Who should use it
Engineering and platform teams at companies that want secure, governed access to many models, dedicated inference, and coding agents under one enterprise contract.
Who should skip it
Individual developers, students, and small teams wanting a free or self-serve coding assistant. Blackbox is now enterprise-only, sold through sales with an annual commit.

Free tier limits: There is no free tier. Blackbox publishes no free plan, no free trial, and no self-serve individual or team plan. Its login page says it is moving to enterprise-only access, and former users are directed to enterprise sales or a refund and account-help form.
Note: Example list rates: DeepSeek V4.1 Flash $0.30/$1.20 and Kimi K3 $3.00/$15.00 per million input/output tokens; input, output, and cached reads are billed separately. Unused commitment expires at the end of the billing period, with spend alerts at 75% and 90%. You can connect your own OpenAI, Anthropic, or Google accounts, in which case that usage bills through your provider. Engagement starts with a sales conversation.

Available models
Where Blackbox AI excels
Standardising model access across an engineering org
The Router puts 300+ models behind one endpoint with encryption, zero data retention, and PII removal, so teams can use many models under one security review.
Delegating repository tasks to cloud coding agents
The Agents API runs coding agents against your repos and opens pull requests, so routine changes can be handed off and reviewed.
Running sensitive workloads on dedicated inference
Single-tenant deployments with data residency options suit teams that cannot send code to shared infrastructure.

Frequently asked questions
Is Blackbox AI free?
No. Blackbox AI has no free plan, and its pricing page publishes no free trial and no self-serve paid plan for individuals or teams. Its login page says it is moving to enterprise-only access. The only published plan is Enterprise: a custom annual commitment, agreed with sales, that is drawn down at per-token model rates with no seat or platform fees. If you need a free coding assistant, GitHub Copilot has a free tier, Cline and Kilo Code are free extensions where you pay only for model usage, and OpenRouter offers free models with daily limits.
What happened to the free Blackbox web app and VS Code extension?
Blackbox's site now presents only the enterprise platform. Its old app dashboard redirects to the homepage, and its login page sends former users to enterprise sales or a refund and account-help form. Both Blackbox VS Code extensions have been unpublished from the Visual Studio Marketplace. A Blackbox plugin is still listed on the JetBrains Marketplace (last updated December 2025), but Blackbox's own site no longer mentions IDE extensions, so don't count on it as a free option.
What is Blackbox AI?

FreemiumAbout Blackbox AI
Blackbox AI began as a coding assistant on its website and in VS Code, with free basic use under its 2024 terms. It now presents itself as 'the high-trust platform for frontier inference' and sells only to organisations. Its login page tells former users it is 'moving to enterprise-only access' and routes them to enterprise sales or a refund and account-help form. Its pricing page publishes one plan, Enterprise, and says the engagement starts 'with a conversation, not a signup'. There is no free plan, no published free trial, and no individual or team subscription. The Enterprise contract is a custom annual committed spend drawn down at per-token list rates (for example, DeepSeek V4.1 Flash at $0.30/$1.20 per million input/output tokens), with discounts of 10%+ on open-weight and 5%+ on closed models, and no platform or seat fees. The products are the Blackbox Router, which exposes 300+ open and closed models (such as Kimi, GLM, Qwen, DeepSeek, and Nemotron families) through one OpenAI-compatible endpoint; Enterprise Inference, with dedicated single-tenant deployments; the Agents API and Remote Agent sandboxes, which run cloud coding agents against your repositories and turn successful runs into pull requests; and an agentic command-line tool with plan mode, headless CI use, and a multi-agent mode that runs Blackbox, Claude Code, Codex, and Gemini on the same task. Security is the main pitch: end-to-end encrypted inference, contractual zero data retention with a DPA, PII removal before requests reach closed models, SAML SSO, SCIM, RBAC, audit logs, and data residency. The VS Code extensions have been unpublished from the Visual Studio Marketplace, and Blackbox's site no longer lists IDE extensions. It fits engineering organisations that want governed access to many models and coding agents under one contract. Individual developers looking for a free or self-serve coding assistant should choose a different tool.
