Pricing Model
FreemiumBlackbox AI has a Freemium consumer tier and an enterprise-focused inference platform with distinct pricing structures. The Free plan offers unlimited chat, VS Code extension access, and select model access with no credit card required. The Pro plan at $10/month provides access to all 300+ models with MCP support, full VS Code agent capabilities, and priority inference. Both are available at product.blackbox.ai/pricing. Blackbox Enterprise Inference is priced per token, not per seat, via an annual purchase order commitment. The base rates (per 1M tokens, list rates): Nemotron 3 Ultra ($0.32 input / $0.80 output), Qwen3.7-Plus ($0.32 / $1.28), GLM-5.2 ($1.40 / $4.40), Kimi K2.7 Code ($0.74 / $3.50), MiniMax M3 ($0.60 / $2.40). Open-weight models (running on Blackbox-operated infrastructure) receive a 10%+ discount; closed models receive 5%+ off provider rates. Enterprise includes dedicated single-tenant deployment, data residency, SAML SSO, SCIM, RBAC, audit logs, zero data retention (contractual + DPA), PII removal before closed models, a forward-deployed engineer (included at no cost), Agents API, custom SLAs, and guaranteed throughput. Unused commitment expires at the billing period end with alerts at 75% and 90% burn-down.
FreemiumJetBrains AI offers four tiers. AI Free is $0/month with 3 AI credits every 30 days, unlimited code completion via JetBrains' Mellum model, and local model support via Ollama or LM Studio, but excludes frontier models and Junie for sustained agentic work. AI Pro is $10/month (Individual) or $20/month (Business), with 10 AI credits per month. AI Ultimate is $30/month (Individual) or $60/month (Business), with 35 AI credits per month, including a $5 bonus over the plan price. AI Enterprise is custom-priced at roughly $60/user/month billed annually, adding organization-wide credit pooling and enterprise controls. Each AI Credit equals $1 USD, and unused top-up credits (purchased separately at $1 each) remain valid for 12 months, while unused monthly plan credits do not roll over. A 30-day AI Pro trial is available for new users. AI Pro is also bundled into JetBrains' All Products Pack and dotUltimate subscriptions.

Blackbox AI Pros & Cons

Pros

  • 4.2M+ VS Code installs — one of the most widely-installed AI coding extensions in the marketplace
  • #1 benchmarked Nemotron 3 Ultra provider at 454 tokens/second (Artificial Analysis, July 2026) — the fastest inference available
  • 300+ models via one endpoint with no seat-based fees on Enterprise — truly usage-based pricing at scale
  • Zero data retention and PII anonymization by default — enterprise-grade privacy without requiring a separate security review
  • Free tier with unlimited chat and VS Code extension available without a credit card — genuinely accessible for individual developers
  • Microsoft Azure partnership enables compliant enterprise deployment on Azure infrastructure for Microsoft-ecosystem teams

Cons

  • Enterprise pricing is commit-based (annual purchase order) with no self-serve monthly plan — requires a sales conversation before starting
  • Relatively newer entrant to the enterprise inference market compared to established providers like OpenAI, Anthropic, and Google
  • AI-native IDE is a newer product and less mature than Cursor or Windsurf as a standalone IDE experience
  • Limited public information on company funding, team size, and revenue makes it harder to assess long-term stability
  • Pro plan at $10/month is narrow in scope — enterprise teams with serious usage needs must engage sales for committed pricing
  • MCP support and multi-agent features (/multi-agent, Chairman LLM orchestration) are metered separately on Enterprise rather than flat-rate included

JetBrains AI Assistant Pros & Cons

Pros

  • Deep semantic project understanding via IntelliJ's existing static-analysis engine, not just open-file context
  • Junie autonomous agent handles multi-file planning, implementation, and self-correction, including a dedicated Debug mode
  • Works across a single subscription spanning 20+ JetBrains IDEs
  • Supports local models via Ollama and LM Studio at zero credit cost
  • Strong enterprise trust features including zero-data-retention policies and .aiignore support

Cons

  • Locked into the JetBrains IDE ecosystem, so it offers no value for developers using VS Code or other editors
  • Credit-based quota system can be confusing, and heavy Junie or Claude Agent use can exhaust monthly credits well before the billing period ends
  • AI Pro's 10 monthly credits are reportedly consumed within about a week under heavy agentic use, pushing users toward costly top-ups ($1 per credit)
  • Best suited to JVM languages (Java, Kotlin); completion quality is reportedly less consistent for other languages
  • AI Free tier excludes frontier models and the Junie agent, limiting it mostly to a demo of completion features
