DON’T REUSE GPT-4 PROMPTS ON GEMINI—EVALUATE MODEL-SPECIFIC PROMPTING

A practitioner write-up claims Google’s latest Gemini model behaves differently from GPT-4 and can underperform if you reuse GPT-style prompts. While the "Gemini 3" naming and internals aren’t confirmed by official docs, the actionable takeaway is clear: treat prompts, tool-calling, and evaluation as model-specific and validate with disciplined A/B tests.
Copy-pasting prompts across models can degrade accuracy and increase hallucinations on code/SQL tasks.
A model-agnostic interface with per-model adapters reduces migration risk and vendor lock-in.
-
terminal
Run an automated eval suite across models for repo-aware code changes, SQL generation, and pipeline scripts, comparing pass rate, latency, and cost with model-tuned prompts.
-
terminal
Validate tool/function-calling schemas, JSON mode, and error handling per model using realistic datasets and integration tests.
Legacy codebase integration strategies...
- 01.
Introduce a shadow rollout that mirrors a small slice of prod LLM calls to the new model with fallbacks and telemetry.
- 02.
Externalize prompts and tool schemas and add a translation layer to avoid sweeping code changes during migration.
Fresh architecture paradigms...
- 01.
Abstract LLM calls behind a provider interface and plan per-model prompts and tool definitions from day one.
- 02.
Stand up an eval harness with golden tasks for your stack (SQL generation, pipeline edits, migration scripts) before shipping.
