Pricing
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.
Customwatsonx pricing varies by product and is largely consumption-based. watsonx.ai offers a free trial with up to 300,000 tokens per month, then a Standard plan starting around $1,050-$1,110/month including a block of capacity unit hours (CUH), with additional usage billed pay-as-you-go; foundation model inference is billed per million tokens, ranging from roughly $0.10/million tokens for select IBM and third-party models up to $20+/million tokens for larger models, with third-party models from Meta, Google, DeepSeek, and Mistral also available on a pay-as-you-go basis. watsonx.data uses tiered plans starting with a free trial and scaling to an Enterprise plan for production data lakehouse workloads, billed per Resource Unit (compute metered per second). watsonx Orchestrate offers a 30-day free trial, then an Essentials plan starting at $500/month for core agent building and orchestration, and a Standard plan (roughly $530+/month per G2 data) with custom, quote-based pricing for higher throughput and prebuilt domain agents. watsonx.governance pricing is quote-based and typically bundled with watsonx.ai and watsonx.data commitments; IBM offers discount tiers for customers committing across multiple watsonx products at $500K, $1.5M, and $5M+ in annual contract value. All products can be purchased through the IBM Cloud Catalog or AWS Marketplace, and on-premises deployment is priced separately through IBM Software licensing.

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

IBM watsonx Pros & Cons

Pros

  • Full-stack enterprise AI portfolio (build, data, govern, orchestrate) from a single vendor
  • Strong AI governance credentials, named a Leader in the 2026 Gartner Magic Quadrant for AI Governance Platforms
  • Model choice within a governed environment, spanning IBM Granite and third-party models from Meta, Google, DeepSeek, and Mistral
  • Flexible hybrid deployment across IBM Cloud, AWS, Azure, or fully on-premises for strict compliance needs
  • Deep enterprise track record with named customers like Vodafone, the US Open, and Dun & Bradstreet

Cons

  • Pricing is complex and fragmented across products, mixing per-token, Capacity Unit Hour, and Resource Unit metrics that require real modeling to estimate total cost
  • Entry pricing is enterprise-scale (watsonx.ai Standard starts around $1,050+/month), pricing out smaller teams and individual developers
  • Full value requires committing across multiple watsonx products, since standalone deployments miss the better multi-product discount tiers
  • Steeper learning curve than single-purpose AI tools, given the breadth of the portfolio
  • Strongest integration and support experience sits within the IBM ecosystem, with less native depth for teams already standardized on AWS, Azure, or GCP-native AI stacks
