[!NOTE]
Please don't abuse these services, else we might lose them for everyone. The number becomes 550+ when you add all the models and sub services of all the tools provided. When raising issues or pull requests please dont add your own paid, expensive personal projects.

[!WARNING]
October 2026 Model Generation Leap: Major providers have transitioned to next-generation architectures: OpenAI introduced the GPT-6 family (GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna); Anthropic deployed the Claude 5.5 generation (Claude Opus 5.5, Claude Sonnet 5.5, Claude Haiku 5.5); Google rolled out gemini 3.8 Flash / Flash-Lite as the default workhorse and previewed Gemini 4 Argon. The new baseline for high-throughput coding and daily development is Claude Sonnet 5.5, GPT-6.1 Sol, and gemini 3.8 Flash, while complex multi-hour reasoning and autonomous sandboxing target GPT-6 Astra and Claude Opus 5.5.

Pricing & Billing Updates: Windsurf switched to a quota-based model (Pro $20, Teams $40, new Max $200) on Mar 18. Trae moved to a 5-tier token system (Lite $3, Pro $10, Pro+ $30, Ultra $100) on Feb 24. Qoder's launch promo ended — standard standalone pricing settled at Pro $30/mo (2,000 credits, or CNY 59/mo on Qoder CN All-in-One), Teams $40/seat (3,000 credits). Cursor split Teams into Teams Standard ($40/seat) & Teams Premium ($120/seat), credited $70 third-party usage on Pro+ ($60/mo), and shifted Bugbot to ~$1.00–$1.50/run. GitHub Copilot summer credit promotion ended Sep 1, 2026 (reverting to standard $19 / 1,900 credits for Business and $39 / 3,900 credits for Enterprise). Xiaomi MiMo V2.5 API permanent pricing schedule flattened to $1.00/1M input, $3.00/1M output, and $0.20/1M cached across all context lengths up to 1M tokens.

🎯 Why This Repo Exists

Most AI tool lists are:

• ❌ Outdated (prices/limits from 2023)
• ❌ Filled with affiliate links and sponsored placements
• ❌ General-purpose directories with no developer focus
• ❌ Missing production-critical details (rate limits, commercial use, architecture patterns)

This repo focuses only on:

• ✅ Tools developers actually use in production
• ✅ Generous free tiers (no "5 requests then paywall")
• ✅ Production-capable models (SWE-bench verified, not toys)
• ✅ Real infrastructure (APIs, hosting, vector DBs, not just chatbots)
• ✅ Minimal fluff, maximum utility

Unlike: awesome-ai (general list), ai-collection (marketing focus), toolify (affiliate-heavy)

This is for: Builders who want to ship AI features this week.

License Summary

All 271 models allow commercial use of generated output. You own what the models generate.

Key Points:

1. Generated code is yours — no model claims ownership of your output
2. Apache 2.0 / MIT models (Qwen, GLM, GPT-OSS, MiMo, Devstral Small) are the most permissive — no strings attached
3. Llama requires "Built with Llama" attribution; >700M MAU needs a Meta license
4. DeepSeek / MiniMax have use-restriction policies (no military use) that govern the model, not your generated code
5. API-served models (Claude, Gemini, Perplexity) grant full output ownership under their terms of service

⚠️ Disclaimer: This is a summary, not legal advice. License terms can change. Always verify the current license on the model's official page before making legal decisions.

Comparison Notes

• Goal: Compare AI coding tools by their access to pro-grade models and free tier limits.
• What qualifies a model as "pro-grade"? Models must achieve ≥60% on SWE-bench Verified / Pro or leading agentic benchmarks (Terminal-Bench 4.0, DeepSWE v1.1), demonstrating real-world software engineering capability. Current qualifying October 2026 models: Claude Opus 5.5 (Flagship Enterprise reasoning, multi-hour sandboxing & prompt-injection defense), GPT-6 Astra (Autonomous Agentic Flagship / Computer Operator), GPT-6.1 Sol (matches Astra on DeepSWE v1.1, leads OSWorld 2.0 & Terminal-Bench Science), Claude Sonnet 5.5 (70.6% Terminal-Bench 4.0, 55.5% CursorBench 4.0, 30% fewer tokens/task), Gemini 4 Argon (Frontier Long-Horizon with 1M output tokens), gemini 3.8 Flash (84.2% CharXiv), and Qwen3.6-Plus (71.2%).
• [verify] tag: Indicates information needs verification from official sources. Pricing, limits, and model availability change frequently.
• Different limit types: Tools use various quota systems - requests, tokens, credits, chats - making direct comparison challenging. Check documentation for specifics.
• Real-world usage: Actual consumption varies dramatically based on coding style, task complexity, and tool implementation.

💵 Model Price Comparison (per 1M Tokens)

API pricing for budget planning. Sorted by input cost.

💡 Pro tip: DeepSeek's 90% cache discount makes it cheapest for repetitive tasks with long prompts.

⚠️ October 2026 Generation Note: Claude Sonnet 5.5 lowered rates to $2.00/$10.00 ($0.20 cache read) with 30% lower token usage per task. GPT-6.1 Sol provides near-Astra capabilities at $2.00/$10.00 ($0.10 cache read). Claude Haiku 5.5 is rolling out to replace Haiku 4.5. Claude Opus 5.5 ($5/$25) and GPT-6 Astra ($10/$50) represent the top enterprise and autonomous tiers.
