What the report covers
- ✓ What changes when the budget sits on a person instead of a team
- ✓ The criteria that cut 70 providers down to a shortlist
- ✓ Where responsibility moves once an intermediary joins the chain
- ✓ How to repeat the measurement on your own tasks
Prerequisites
- → A team already paying for models per use
On 14/09/2026, Nicolas Martignole published a 2-month review of Back Market running on OpenRouter with 245 internal users. He gives the figures, the provider selection method and what he would do differently.
The report above takes those statements, checks them against OpenRouter’s documentation and other public accounts, and separates what is verified from what is not.
The video and the report are in French. This page summarises both in English.
TL;DR
I do not judge Back Market’s OpenRouter setup: this is a third party’s experience, and I did not run it myself.
What it shows for a team paying per use: a cap per person instead of per team, a provider shortlist driven by data policy rather than listed price, and a longer liability chain once an intermediary joins.
If you repeat the measurement, compare the cost per task actually resolved, not the price per token. FinOps applied to tokens develops the budget-ownership question, while measuring your own AI usage separates invoices, quotas and local usage estimates.
Our November 5, 2026 Insitoo discussion adds a shared-quota case: support experiments used up the allowance developers also relied on.
November 10, 2026 update. The report separates September’s routing account from current routing. Default provider selection now weighs effective price, speed and reliability. The model-price comparison retains its September 16 snapshot.
What the report establishes
Back Market replaced direct Anthropic access with an intermediary that exposes several providers behind one API. 3 decisions shape the rest:
- A budget of $200 per developer per month, reset every month, with an overrun procedure. The cap sits on the person, not on the team.
- A shortlist of about 10 providers, kept out of the 70 the catalogue offered. The criterion is each provider’s data policy, not its listed price.
- A liability chain that gets longer. The intermediary is not the model provider, and every provider on the shortlist brings its own terms.
What the report does not say
It does not compare models against each other, does not rank quality and does not recommend a provider. Amounts stay in dollars, as in the source. Any figure that no primary source confirms is marked as such.
Who it is for
For a team already paying for models per use and looking to regain control of the spend without banning the tool. The last part describes how to repeat the measurement: point Claude Code at a router, set a per-key cap, then compare the cost per task actually resolved rather than the price per token.
