From a 5,000-Line JSON to 18 Vendor Files: Mapping the World of AI Models
*Source: easy-learn-ai commit e6c189a*
Background
In 2023, keeping track of large language models was easy — a single page could list them all. By 2025–2026, hundreds of models from dozens of companies compete for attention, with confusing naming schemes (GPT-4o, GPT-5.1, Claude 4.5, Qwen3.5, Gemini Flash...). The open-source easy-learn-ai project, an AI learning site for beginners, originally stored its entire model catalog in one JSON file of over 5,000 lines — hard to update, with no structure for model "family" relationships (e.g., DeepSeek-R1 and its distills).
The maintainer recently split this monolith into 18 independent files, one per AI vendor — US side: OpenAI, Google, Anthropic, Meta, xAI, Midjourney, Runway, Pika, Stability AI, Black Forest Labs; China side: Alibaba, Baidu, ByteDance, DeepSeek, Moonshot AI, MiniMax, Zhipu AI, Tencent, Kuaishou — totaling over 6,000 lines of data.
Key points
Model highlights by vendor
- OpenAI: GPT-4 → GPT-4 Turbo → GPT-4o ("omni", first true multimodal model) → GPT-4.1 → GPT-5 → GPT-5.1. GPT-4o mini targets cheap, high-volume tasks.
- Anthropic: Claude tiering named after literary forms — Opus (flagship, complex coding/research), Sonnet (best value), Haiku (fastest). Latest Claude Opus 4.8 handles 1M-character contexts; Sonnet 4.6 reportedly beats GPT-5.2 on coding benchmarks.
- Google: Gemini's huge context windows (Gemini 2.0/3.5 Flash support 1M+ tokens), plus unique ecosystem integration with Search, Docs, and Gmail.
- Meta: Llama open weights let small teams run near-GPT-4-level models locally. Llama 4 Maverick uses a Mixture-of-Experts architecture (400B total, 17B active); Llama 4 Scout reaches a 10M-token context window.
- DeepSeek: R1 matches OpenAI o1 in math/code reasoning at a fraction of the training cost; its reasoning is distilled into small models (1.5B–70B), all fully open source. A 1.5B distill reportedly beats GPT-4o on math competitions.
- Alibaba (Qwen): Qwen3.5-Plus has 397B total/17B active parameters, outperforming trillion-parameter rivals at 1/18 the price of Gemini 3 Pro; Qwen3.7-Max supports 1M-character context and 64K output.
- Moonshot AI (Kimi): doubled down on long context, from 200K up to 2M characters — strong in legal document analysis and research.
- ByteDance: Doubao/Seed models are highly "engineering-oriented", multimodal (text/image/video) with tool use; open-source Seed-OSS-36B supports 512K context, backed by Douyin/Toutiao data.
- Baidu (ERNIE): knowledge-graph-enhanced training reduces hallucination; ERNIE-5.1-Thinking supports 128K context and output, integrated with Baidu Search.
- Regular users: far more choice at lower cost — free tiers like DeepSeek for daily tasks, Kimi for long documents, Doubao for image/video, Claude for coding, Gemini for Google Workspace.
- Developers/enterprises: build model-selection capability across cost, security, latency, and capability rather than chasing the newest release.
Industry trends the refactor reveals
1. Model tiering: flagship (Opus, GPT-5, Qwen3.7-Max) → cost-effective (Sonnet, Gemini Flash) → lightweight (Haiku, DeepSeek-Distill-1.5B) → domain-specific (coding models). Choose by fit, not price. 2. Open vs. closed convergence: by 2026, open models (DeepSeek-R1, Llama 4, Qwen3.5) match or beat many closed models; enterprises increasingly adopt hybrid strategies — local open models for sensitive data, cloud closed models otherwise. 3. Context window arms race: from GPT-4's 8K tokens (2023) to 1M+ tokens (2026), enabling whole-book reading, full codebase analysis, and hours of meeting transcripts — shifting AI from Q&A chat to deep collaboration. 4. Rise of Chinese vendors: nearly half of the 18 vendors are Chinese, leading in long context, open-source downloads (Qwen), aggressive pricing (DeepSeek API at ~1/50 of OpenAI's), and multimodal generation.
What it means for you
Takeaway
The refactor itself is mundane file reorganization, but its value is clear: in an era of information explosion across hundreds of models and monthly release cycles, building an ordered map of the AI landscape is a real contribution — you cannot choose well if you do not know what the options are.
