When to use

Optimised for: multilingual (119 languages including Asian + minor European); cost-efficient inference; permissive Apache 2.0 OSS

Anti-fit: China data-residency for regulated Western workloads; less mainstream Western enterprise adoption; Qwen-Max not open-weights

Pros & cons

Pros

Broadest open-weights frontier family (0.5B to 235B); Apache 2.0 (most permissive); 119-language coverage; strong reasoning at small / medium sizes; #1-ranked OSS family on HF for many months 2024-25.

Cons

China-based — regulatory risk for some Western enterprises; multimodal less polished than Gemini 3; Qwen-Max tier (rumored 1T+) is closed.

Claims & capabilities

Qwen 3 family Apache 2.0; 0.5B to 235B-A22B MoE; 119 languages; thinking/non-thinking dual mode; matches DeepSeek R1 on reasoning at smaller sizes

  • Anthropic Claude (foundation models) T1

    Claude family of frontier foundation models — Sonnet 4 (workhorse), Opus 4.5 (frontier capability), Haiku 4.5 (fast/cheap). Frontier model used as substrate by Claude Code, Anthropic Memory tool, Cline, Aider, Continue.dev, Cursor, Goose, and dozens of other catalog entries. Memory in Claude is parametric (in weights) — discrete episodic memory lives outside the model in the Claude Memory tool (see Platform-provider memory section).

  • OpenAI GPT family (GPT-5 / GPT-4o / o3 / o4) T1

    OpenAI's foundation model family — GPT-5 (2025-08 flagship), GPT-4o (multimodal workhorse), o3/o4 reasoning series. Substrate for ChatGPT, the OpenAI API, Microsoft Copilot, Azure OpenAI, and many downstream agents in this catalog (Devin, Codex CLI, Operator, Cursor mode). Parametric memory in weights; discrete user memory ships in ChatGPT Memory feature (separate row).

  • Google Gemini 3 family T1

    Google DeepMind's Gemini 3 frontier model family — Gemini 3 Pro (top tier), 3 Flash (fast), 3 Nano (on-device). Substrate for Google Workspace AI, Vertex AI Agent Platform, Gemini Code Assist, Project Mariner, and Project Astra. Multimodal-native; 1M-10M context window. Largest context window of any frontier model. Used by Gemini Enterprise Agent Platform Memory Bank (separate row).

  • Mistral Large 2 / Mixtral family T1

    French frontier-model lab (Paris). Family includes Mistral Large 2 (123B dense, Jul-2024), Mixtral 8x22B (open-weights MoE), Mistral Small 3 (24B, open-weights Jan-2025), Codestral (code specialist). EU-headquartered alternative to US/China model labs; GDPR-friendly data residency. Distinct from the Mistral Le Chat memory feature (already in catalog) — this row covers the model family itself as substrate.

  • Meta Llama 4 family T1

    Meta's Llama 4 family (released 2025-04) — Scout (109B MoE, 17B active), Maverick (400B MoE, 17B active), Behemoth (2T MoE, 288B active; preview). First Llama generation to use mixture-of-experts and to be multimodal-native. Substrate for many OSS agents (Open-Interpreter, Ollama-served local agents, vLLM-served enterprise inference). Llama community license (commercial use permitted under 700M MAU threshold).

  • xAI Grok 4 T1

    Elon Musk's xAI frontier model — Grok 4 launched 2025-07. Trained on Colossus (100k+ GPU supercluster in Memphis). Deeply integrated with X/Twitter (real-time tweet data access). Grok 4 Heavy variant for premium tier. No frontier-tier open-weights — Grok 1 (314B MoE) is the only weight release.
