DeepSeek R1 / V3 family

https://www.deepseek.com/

DeepSeek (Hangzhou-based, Liang Wenfeng founder) — released DeepSeek-V3 671B MoE (37B active) Dec-2024, then R1 reasoning model Jan-2025 that matched o1 at ~3% of inference cost. Caused 'DeepSeek moment' in markets Jan-27-2025 — NVIDIA dropped 17%. MIT license. Substrate for cost-conscious OSS deployers and an active reasoning-research baseline.

When to use

Optimised for: cost-efficient frontier reasoning; OSS-friendly deployment; distillation source for smaller models

Anti-fit: China data-residency for regulated Western workloads; export-control posture; less polished tool-use than Claude/GPT; multimodal less mature

Pros & cons

Pros

MIT-licensed frontier weights; ~3% the inference cost of peers; R1 matches o1 on math/reasoning; spawned a wave of cheaper distilled reasoners.

Cons

China-based — geopolitical and regulatory risk for Western enterprises; tool-use less polished; multimodal lagging; dataset / training-data transparency limited.

Claims & capabilities

R1 matches o1 on AIME/MATH at ~3% the cost; V3 671B MoE / 37B active / 128k context; MIT license (one of most permissive for frontier weights); used for distillation into smaller Qwen / Llama variants

  • 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.
