Pricing
PaidThe OpenAI API uses pay-as-you-go, per-token pricing that varies by model. GPT-5.6 Sol, built for complex reasoning and coding, costs $5.00 per 1M input tokens and $30.00 per 1M output tokens with a 1.05M context length. GPT-5.6 Terra, balancing intelligence and cost, costs $2.00 per 1M input tokens and $12.00 per 1M output tokens. GPT-5.6 Luna, designed for cost-sensitive, high-volume workloads, costs $0.20 per 1M input tokens and $1.20 per 1M output tokens. All three share a 1.05M context length and 128K max output tokens. Additional costs apply for fine-tuning, evals, and specialized tools like web search or file search depending on usage. New accounts must add billing details before making live API calls, and there is no free-tier token quota; enterprise organizations can contact sales for custom pricing, dedicated support, and advanced data residency and retention controls.
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.
