Costs are higher and more volatile. GPT-5.1 is 20% cheaper than GPT-5 for database execution. Token bloat is down. Default reasoning set to none instead of medium. ## For advanced analysis planning (single API call, reasoning step) * **Gemini 2.5 Flash**: strong quality, predictable costs * **KIMI 2**: similar quality, costs are higher and more volatile * **GPT-5.1**: high quality, high cost * **Claude Sonnet 4.5**: highest quality, highest cost * **GPT-5 / Gemini-2.5-Pro**: avoid on APIs - major token and cost bloat ## For database execution (where 80% of cost sits) * **GPT-4.1-mini**: my current workhorse for simple to medium work, very cost effective * **GPT-4.1**: complex queries, strong at debugging, 30% cheaper than GPT-5.1 * **GPT-4o-mini**: high volume work, half the cost of GPT-4.1-mini GPT-5-mini still has token bloat. Default reasoning is medium. For regular work, GPT-4.1-mini is better. For more firepower ramp up stepwise → GPT-4.1 → GPT-5.1 ## Planning vs execution costs In multi-step advanced analysis workflow, for a single iteration, planner runs once. Execution agent runs 7 to 10 queries and debugs. Planning is 20% of cost. Execution is 80%. ## Avoid multi-step unless needed Multi-step workflows multiply costs fast. Single step: approx. $0.40 per 100 questions with a GPT-4.1-mini. Advanced analysis: approx. $15 per 100 questions depending on LLM. Use multi-step multi-agent workflows only when needed. ## DATS-4 (Database AI Suite v4) Database AI app. Connects to Postgres or MySQL. Two workflows: simple text-to-sql and advanced multi-step analysis. Supports python charts, table upload, export, PDF reports. ### Try it Sample button uploads test data to temporary Postgres instance. Use sample prompts. Or upload your files to a temp DB / connect to your DB. ### Note Public app routes through my backend. Sandbox testing only. For production, deploy on your servers. ## Related Tools: [DATS-4 Database AI Suite](https://www.tigzig.com/analyzer), [BRIQ](https://www.tigzig.com/briq), [ChatGPT to Any Database](https://www.tigzig.com/rex2-gpt) Explore: [Database AI Apps](https://www.tigzig.com/database-landing), [Database Query Tool (MCP)](https://www.tigzig.com/apis/database), [APIs and MCP](https://www.tigzig.com/apis) More posts: [Gemini 3 Pro on Database AI Suite - Claude 4.5 still leads](https://www.tigzig.com/post/gemini-3-pro-added-to-database-ai-suite-tested-against-claude-sonnet-4-5-and-gpt-5-1-results-claud), [Sonnet 4.5.
