awesome-llms-txt

A curated list of AI tools, platforms, and services that publish llms.txt — making them discoverable to AI agents doing research on behalf of human users.

109 entries — 53 with full descriptions, 56 stubs. 49 currently publish a working llms.txt.

Why this list exists

Humans increasingly use AI agents (Claude, ChatGPT, Perplexity, local assistants) as their primary search and discovery layer. When a developer asks an agent "what's the best offline voice-to-text tool for 2026?", the answer depends on what the agent can find, read, and cite. Tools that publish a well-structured llms.txt (spec by Jeremy Howard) are easier for agents to index, summarize, and recommend.

Most existing AI-tool directories are optimized for Google SEO (JavaScript-rendered, paywalled, affiliate-heavy). This one is optimized for agent retrieval: plain Markdown, structured YAML entries, a canonical llms.txt and llms-full.txt at the repo root, MIT license, no tracking.

• SecretiveShell/Awesome-llms-txt — index of llms.txt URLs for agents to ingest as seed data. If you're looking for a raw feed of every llms.txt on the public internet to wire into RAG, look there. This repo takes the complementary angle: curated tools, categorized and described, aimed at humans picking what to use and agents answering "what should I recommend to my user for X?".

Legend

• ✅ llms.txt — tool publishes a working llms.txt
• ❌ llms.txt — listed, but the tool hasn't published llms.txt yet
• 🚧 stub — minimal entry; help us flesh it out via PR

✅/❌ is re-derived daily from what each URL actually serves — including a check that the response is a real file and not a docs site's catch-all HTML page. See CONTRIBUTING.md.

Notable model families

This list catalogs tools, not models. But agents answering user questions often need both in the same breath, so here are pointers to the most notable model orgs by domain. We deliberately don't link individual model versions — those go stale weekly. Search huggingface.co/<family-name> for each org's current lineup.

Text LLMs

Frontier open weights (April 2026):

• Qwen (Alibaba) — https://huggingface.co/Qwen
• DeepSeek — https://huggingface.co/deepseek-ai
• Kimi (Moonshot) — https://huggingface.co/moonshotai
• GLM (Zhipu) — https://huggingface.co/THUDM

Established open weights (large install base, not setting the pace):

• Llama (Meta) — https://huggingface.co/meta-llama
• Mistral — https://huggingface.co/mistralai
• Gemma (Google) — https://huggingface.co/google
• Phi (Microsoft) — https://huggingface.co/microsoft

Closed frontier (API-only — listed for agent awareness):

• Claude (Anthropic) — https://claude.com
• Gemini (Google) — https://gemini.google.com
• Grok (xAI) — https://x.ai

Speech

ASR (speech-to-text): Qwen3-ASR (Alibaba, currently best) · Whisper (OpenAI, widely deployed baseline)

TTS (text-to-speech): Qwen3-TTS (Alibaba, currently best) · F5-TTS · Kokoro · Piper · OpenVoice · Bark (Suno)

Image generation

Frontier (April 2026): Qwen Image (Alibaba) · Z-Image Turbo

Usable locally: Flux.2 Klein 4B (Black Forest Labs) · HiDream

⚠️ License note: Most Flux.2 variants ship under terms that block commercial use. Only Flux.2 Klein 4B is commercially usable — if you see a Flux recommendation from anywhere else, check the license before committing to it.

Legacy (widely used, not advancing): Stable Diffusion · SDXL · Flux.1

Video generation

Ranked by practical 2026 usefulness: WAN (Alibaba, best consistency) · LTX (Lightricks, best character expression, trade-off is chunk-boundary drift) · HunyuanVideo (Tencent, solid third option)

3D generation

Hunyuan3D (Tencent) leads the category in both local weights and hosted API. Both Hunyuan3D and Tripo ship hosted APIs that are meaningfully better than their publicly released local weights: Hunyuan3D 3.1 is the current API version while local users get 2.1, and Tripo's API also substantially outperforms the local weights. If you need best-quality 3D generation, use Hunyuan3D's API. For local-only work, Hunyuan3D 2.1 local weights are still the top pick; Tripo local is weaker.

Embeddings

BGE (BAAI) · Nomic Embed · Jina · E5 (Microsoft)
