Quality Comparison for OpenClaw Tasks

Conversational Intelligence

Winner: Claude 3.5 Sonnet — best at nuanced conversation, understanding context, and following complex instructions. GPT-4o is close. DeepSeek V3 is surprisingly capable for its price.

Code Generation

Winner: Claude 3.5 Sonnet — consistently produces correct, well-commented code. GPT-4o similar. Haiku and DeepSeek struggle with complex multi-file codebases.

Task Planning and Multi-Step Reasoning

Winner: Claude 3.5 Sonnet — handles complex skill chains and multi-step automations best. Haiku often loses track of context in extended planning tasks.

Summarisation and Writing

Winner: Tie (Claude / GPT-4o / DeepSeek V3) — all models produce good summaries. DeepSeek V3 is surprisingly strong for its price point on writing tasks.

Tool Use and Function Calling

Winner: Claude 3.5 Sonnet / GPT-4o — most reliable for multi-tool skill chains. Haiku and smaller models occasionally hallucinate function parameters.

Recommended Configuration

For maximum quality: Claude 3.5 Sonnet as default.

For best value: DeepSeek V3 as default, Claude Sonnet for code generation tasks only. Achieves ~80% of the quality at ~10% of the cost.

For minimum cost: Gemini 1.5 Flash as default (excellent context window, very low cost). Upgrade to Claude for complex tasks.

Hybrid approach (recommended):

Frequently Asked Questions

Which model handles long conversations best?

Claude 3.5 Sonnet with its 200K context window handles very long conversations better than GPT-4o Mini (128K) or DeepSeek V3 (64K). For extended sessions, the larger context window has real value.

Is DeepSeek private?

DeepSeek processes requests on servers based in China. If data sovereignty is a concern, use Anthropic or OpenAI models, or self-host Qwen or Llama models locally.
