Claude 4
Anthropic
Claude 4 is Anthropic's next-generation family of large models delivering more reliable, interpretable assistance for complex work, learning, and coding.
Key features
- Interpretable Outputs: Produces explanations and stepwise reasoning to make model decisions more transparent and easier to audit for correctness and safety.
- Improved Reliability: Enhanced instruction-following and reduced hallucinations compared to prior generations, designed for complex multi-step tasks across domains.
- Model Family Variants: Offered as multiple specialized variants (e.g., Sonnet for agentic and general tasks, Opus for coding) enabling selection of models optimized for coding, agents, or general assistance.
- Developer Platform Integration: First-class support on the Claude Developer Platform with API access, quickstarts, and SDKs to embed Claude models into apps, agents, and workflows.
- Large Context and Multi-Stage Reasoning: Engineered to handle extended context and interleaved/thinking-style prompting patterns to manage longer documents and multi-step reasoning processes.
- Agent & Tooling Support: Designed to work with agent frameworks, tool integrations, and products like Claude Code to interact with codebases, execute tasks, and manage git workflows via natural language.
- High‑capability natural language reasoning and multi‑step task completion
- Improved interpretability and reliability for critical workflows
- Accessible via the Claude Developer Platform and Claude API with API key access
- Integrates with developer tooling: Claude Code CLI (npm package), quickstarts, SDKs and cookbooks
- Support for agentic coding workflows, git automation, and codebase understanding (Claude Code)
- Used in Anthropic apps (mobile iOS app) and third‑party integrations (e.g., GitHub Copilot support)
- Examples, recipes, and reference implementations available in public repositories (claude-quickstarts, claude-cookbooks)
Best for
- Long-form research synthesis: Analyze and summarize large document sets, extracting insights, sources, and stepwise justifications for informed decision-making.
- Developer assistance and code generation: Review, debug, and generate complex code across languages using Opus-optimized variants and Claude Code integrations to operate on repositories.
- Agentic automation: Power multi-step agents that call tools, manage context windows, and delegate subagents for specialized subtasks in customer support or data workflows.
- Enterprise knowledge workflows: Integrate Claude into internal tools to index, query, and reason over company documents, policies, and project artifacts with interpretable outputs.
- Educational tutoring and learning: Provide step-by-step explanations, problem solving, and personalized learning assistance across subjects with reliable reasoning traces.
- Document analysis and synthesis: Extract structured data, generate executive summaries, and produce action items from lengthy reports, contracts, or meeting transcripts.
- Developer tooling: code generation, debugging, and automated git workflows via Claude Code
- Knowledge work: research summarization, document analysis, and project organization
- Agentic applications: building autonomous assistants and task automation agents
- Customer support: automated responses, triage, and assisted agent workflows
- Content workflows: document parsing (PDFs), moderation filters, and prompt/evaluation automation
- Mobile productivity: on‑device assistant features and visual analysis in apps
Laguna by Poolside
Poolside
Poolside's family of open Mixture-of-Experts foundation models for agentic coding — XS.2 runs locally, M.1 reaches 72.5% on SWE-bench Verified.
Key features
- Two Model Sizes: Laguna XS.2 (33B total / 3B active) and Laguna M.1 (225B total / 23B active) target different latency and capability needs.
- Mixture-of-Experts Architecture: Routes each token through a subset of experts for efficiency at large scale.
- Local Deployment: XS.2 is small enough to run on a Mac with 36 GB of RAM via Ollama under an Apache 2.0 license.
- Strong SWE-bench Results: XS.2 hits 68.2% and M.1 reaches 72.5% on SWE-bench Verified.
- Bundled Coding Agent: Ships 'pool,' a lightweight terminal-based coding agent.
- Agent Client Protocol: Includes a dual ACP client-server used internally for agent RL training and evaluation.
Best for
- Local Agentic Coding: Running XS.2 on a laptop for private, offline code generation and editing.
- High-Capability Code Tasks: Using M.1 for harder, long-horizon software engineering work.
- Self-Hosted Deployments: Building on open weights to avoid third-party API dependencies.
- Research & Fine-Tuning: Adapting permissively licensed weights for custom coding workflows.
- Benchmarking: Evaluating agentic coding performance against SWE-bench Verified and Pro.
