Premium Reasoning on Magicdoor

Magicdoor does not list GPT-5 Pro in its current managed model lineup. If you want the strongest reasoning options currently available on the platform, the practical substitutes are:

• Claude Opus 4.6 for highest-end reasoning and writing
• GPT-5.4 for strong general-purpose analytical work
• Qwen 3 Thinking for lower-cost structured reasoning
• Perplexity Deep Research when the job depends on current web sources

Which model to use

Claude Opus 4.6

Use it when:

• the task is high stakes
• you need careful synthesis across many ideas
• you want stronger writing quality in the final output

GPT-5.4

Use it when:

• you need a strong all-round analytical model
• the task involves coding, planning, or structured problem solving
• you want flagship-level quality without jumping to the most expensive option

Qwen 3 Thinking

Use it when:

• you want explicit reasoning at a lower cost
• you are exploring several approaches before committing to a premium model
• the task is analytical but not mission critical

Perplexity Deep Research

Use it when:

• the answer depends on current information
• you need sourced research rather than training-data-only reasoning
• you want a research pass before switching to Claude or GPT for synthesis

Practical workflow

Option 1: Research then synthesize

1. Start with Perplexity Deep Research to gather current information.
2. Switch to Claude Opus 4.6 or GPT-5.4 to synthesize, argue, or write.

Option 2: Cheap first pass, premium second pass

1. Start with Qwen 3 Thinking to structure the problem.
2. Move to GPT-5.4 or Claude Opus 4.6 only if the task deserves the extra cost.

Option 3: Default analytical workflow

1. Use GPT-5.4 for the main reasoning pass.
2. Use Claude Opus 4.6 for a second opinion or final rewrite.

Cost perspective

Current token pricing on Magicdoor:

• Claude Opus 4.6: $5 input / $25 output per 1M tokens
• GPT-5.4: $2.50 input / $15 output per 1M tokens
• Qwen 3 Thinking: $0.65 input / $3 output per 1M tokens
• Perplexity Deep Research: token pricing plus per-request pricing

That usually means the smartest move is not to force one premium model onto every task. Use the expensive model only on the part of the workflow that actually benefits from it.

Bottom line

If you landed here looking for GPT-5 Pro, the current Magicdoor answer is:

• use GPT-5.4 for strong general reasoning,
• step up to Claude Opus 4.6 for the hardest synthesis and writing work,
• use Qwen 3 Thinking when cost matters,
• and use Perplexity Deep Research whenever live web information is part of the job.
