Pricing
CustomTabnine no longer offers a public free tier and is sold as two annual-subscription plans. The Code Assistant Platform costs $39 per user per month and includes AI code completions, in-IDE chat across leading LLMs, Atlassian Jira integration, flexible deployment (SaaS, VPC, on-prem, or air-gapped), zero code retention, SSO, and enterprise compliance (GDPR, SOC 2, ISO 27001). The Agentic Platform costs $59 per user per month and includes everything in the Code Assistant Platform plus autonomous coding agents, the Tabnine CLI, and the Enterprise Context Engine with unlimited codebase connections to Bitbucket, GitHub, GitLab, and Perforce. Usage is unlimited when customers bring their own on-prem or cloud LLM endpoint; using Tabnine-provided LLM access requires a reserved token consumption quota billed at the underlying LLM provider's price plus a 5% handling fee. A Headless Agents add-on for CI/CD use is priced separately. Exact quotes require contacting Tabnine sales, as pricing is not self-serve.
FreemiumThe Gemini API uses a three-tier structure. Free is for developers and small projects, offering limited access to select models with free input and output tokens, Google AI Studio access, and no billing account required, though content is used to improve Google's products. Paid unlocks higher rate limits for production, context caching, the Batch API (roughly 50% cost reduction), access to Google's most advanced models, and a guarantee that content is not used to improve Google's products. Pricing is billed per million tokens and varies by model: for example, Gemini 3.1 Pro Preview costs $2.00 input and $12.00 output per million tokens for prompts under 200K tokens, while cost-efficient options like Gemini 3.5 Flash-Lite start as low as $0.30 input and $2.50 output per million tokens, with additional Flex and Priority billing modes available for different latency and cost tradeoffs. Enterprise is for large-scale deployments through the Gemini Enterprise Agent Platform, adding dedicated support channels, advanced security and compliance certifications (HIPAA, SOC 2, FedRAMP), provisioned throughput, volume-based discounts, and MLOps tooling, available by contacting Google's sales team.

Summary
Privacy-first AI coding platform with completions, chat, and agentic workflows
Build with Google's multimodal Gemini models via API and AI Studio
Tabnine Pros & Cons
Pros
- Zero code retention and no training on customer code, a core differentiator for IP-sensitive organizations
- Flexible deployment including fully air-gapped installs for the most security-conscious industries
- Supports multiple leading LLMs and allows bring-your-own-model for unlimited usage
- Enterprise Context Engine grounds AI suggestions and agents in real organizational architecture and standards
- One of the earliest and most established AI coding assistants, with over a decade of product maturity
Cons
- No public free tier anymore; entry pricing starts at $39 per user per month with annual commitment
- Recent acquisition by Tricentis introduces uncertainty around long-term product direction and roadmap
- Enterprise-grade governance and air-gapped deployment options are geared toward larger organizations, more than solo developers need
- Full agentic workflows and the Context Engine require the higher $59/user/month Agentic Platform tier
Google Gemini API Pros & Cons
Pros
- Genuinely native multimodal models covering text, image, video, and audio in one API
- Google AI Studio offers a real, usable free prototyping environment with no billing account required
- Google Search and Google Maps grounding help reduce hallucinations with live information
- Batch API and Flex pricing modes offer substantial cost savings for non-latency-sensitive workloads
- Clear upgrade path from free prototyping to enterprise-grade deployment via the Gemini Enterprise Agent Platform
Cons
- Pricing structure is complex, with per-model, per-mode (Standard/Batch/Flex/Priority) rates that require careful reading to estimate real costs
- Free tier usage is used to improve Google's products, so privacy-sensitive projects need to upgrade to the Paid tier for that guarantee to apply
- Frequent model churn (previews, deprecations, shutdown dates) means integrations need occasional migration work to stay current
- Full enterprise-grade features like fine-tuning, VPC Service Controls, and CMEK live on the separate Gemini Enterprise Agent Platform, not the Developer API itself
- Advanced capabilities like Computer Use and some agent tooling remain in preview with more restrictive rate limits
