Pricing
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.
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).

Google Gemini API

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
Codeium

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
