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.
FreemiumCodeium launched with a genuinely free tier for individual developers — unlimited code completions, chat, and search across 70+ languages and 40+ IDEs with no time limit or credit cap. Enterprise plans (custom pricing) added on-premises deployment, SOC 2 compliance, SSO, and zero code retention. After launching the Windsurf Editor in November 2024, the company introduced paid tiers: Free ($0) with unlimited Tab autocomplete and a light agent quota; Pro ($15/month, later raised to $20/month in March 2026) with full model access, standard refreshing agent quota, and Cascade; Teams ($30/user/month); and Enterprise ($60/user/month) with SSO, 1,000 prompt credits, and enhanced security. Following Cognition AI's acquisition and the June 2026 rebrand to Devin Desktop, pricing is now managed under Cognition's Devin plan structure: Free ($0), Pro ($20/month), Max ($200/month), Teams ($80/month + $40/seat), and Enterprise (custom). The codeium.com/pricing URL now redirects to devin.ai/pricing.

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

Codeium Pros & Cons

Pros

  • Genuinely unlimited free tier for individual developers — no credit limits or trial expiry
  • Broadest IDE coverage of any AI coding tool with 40+ editor integrations at launch
  • Rapid iteration: went from plugin to agentic IDE and $100M ARR in under 3 years
  • Enterprise-grade security with on-prem/VPC deployment, SOC 2, and zero code retention options
  • Cascade/Windsurf Editor introduced flow-aware multi-file agentic coding before competitors
  • Backed by top-tier investors and reached $1.25B unicorn valuation in just 2 years

Cons

  • Rebranded twice (Codeium → Windsurf → Devin Desktop) creating confusion and instability for users
  • Original Codeium extension identity sunset — codeium.com now redirects to Devin/Cognition
  • Pro pricing rose from $15 to $20/month in March 2026, removing its budget pricing edge over Cursor
  • Cascade agent fully retired July 1, 2026 — replaced by Devin Local under new ownership
  • Heavy agentic workflows require Pro plan; free tier agent quota is limited
  • Brand owned by Cognition AI (Devin), not the original Codeium/Windsurf founding team
