Claude Sonnet

You do not need anythingore than Haiku or Sonnet. Opus and fable are overkill for this task.

Then use Claude sonnet to review, ask scoping questions, and optimise it for use with Claude Opus, before getting to the actual work.

On the vLLM deserialization-RCE regression and the Parse Server operator-injection-account-takeover regression, Claude Sonnet and Gemini 2.5 Pro caught the bug on all 3 runs

I actually only have my multi-model built for client interaction, I only use Claude Sonnet (rn) for the audit. My rationale was I always wanted one voice speaking to the client in that area.

Use Claude Sonnet to build the first prototype.

Used Claude Sonnet + ChatGPT aggressively for hard-mode drilling get the note from your weakness throw to them and ask them to drill you combatant mode

I gave all 5 prompts to claude sonnet (same model, same day, fresh conversations) and rated each output on specificity, actionability, and quality of strategic thinking. ... result: the best output. the extra contextual details that came out naturally through speaking made the strategy more specific.

Used Claude Sonnet + ChatGPT aggressively for hard-mode drilling get the note fromyour weakness throw to them: RBAC inheritance, VNet peering, storage redundancy, NSG order, backup scenarios, least-cost vs least-admin questions.

Sonnet would do it better, sure, but my current cost is around $0.10 per finished article for the full cycle, and replacing Haiku with Sonnet for that step would kill the economics pretty fast.
