The best AI model for writing freelance proposals

Scoring and proposal writing are different jobs. Here is how to pick a model for each, and why bring-your-own-key puts you in charge of cost and quality.

BidZero uses two model roles per account: a Scoring model that judges fit, and a Proposal model that writes. They have different needs, so the best pick is rarely the same model for both.

Scoring wants cheap and consistent

Scoring runs on every fetched project, so it should be fast and inexpensive. A smaller, reliable model that returns steady sub-scores for skills, budget, and category is ideal here, you are filtering, not writing.

Proposals want nuance

The proposal model only runs on projects that clear your threshold, so you can afford a stronger model. This is where a more capable model earns its keep, picking up the brief’s nuance and matching your tone.

Spend your tokens where they change the outcome: a few strong proposals, not a thousand throwaway scores.

Bring your own key, switch any time

Because BidZero is bring-your-own-key, you can mix providers, OpenAI for scoring, Anthropic for proposals, or whatever fits your budget, and change them per account without leaving the app.
