# Devstral API Rate Limits, Pricing & Performance (July 2026)

- Tool: AI API Limits & Performance Matrix
- Last updated: July 2026

## TL;DR

Devstral is Mistral AI's hosted code-specialist model on La Plateforme, with a 256K token context window. The free Experiment tier provides roughly 1 billion tokens/month for evaluation; pay-as-you-go unlocks an estimated ~300 RPM baseline with no monthly minimum. Pricing is approximately $0.30/$0.90 per MTok in/out (per third-party trackers — verify on mistral.ai/pricing before quoting).

## Frequently asked questions

### How do I increase Devstral API rate limits?

Start by adding a billing card to your La Plateforme account, which immediately upgrades you from the free Experiment tier to the pay-as-you-go baseline (~300 RPM per third-party trackers). Then check Admin Console → Limits for your current org ceilings — some self-serve increases are available without contacting support. For higher custom limits, contact Mistral sales or apply to the Mistralship startup program for ~$30K in credits.

### Is the Devstral API free?

Yes — Mistral offers a free Experiment tier with no billing card required. It includes approximately 1 billion tokens per month but has a low RPM ceiling (not published publicly; check Admin Console → Limits). It is intended for evaluation, not production. Paid pay-as-you-go access unlocks higher limits with no monthly minimum.

### What is Devstral's API pricing?

Per third-party trackers, Devstral is approximately $0.30 per million input tokens and $0.90 per million output tokens — verify on mistral.ai/pricing before quoting, as Mistral describes the price as 'between Small and Medium tiers' without a published figure. A 50% batch discount is available on supported models. Context caching discounts repeated-prefix input at a rate not yet published.

### Devstral vs Codestral — what's the difference?

Codestral is Mistral's IDE autocompletion model with a dedicated free tier for tools like Continue.dev and VS Code plugins. Devstral is a separate agentic code-editing model designed for multi-step coding tasks and PR workflows. They have different endpoints, different pricing, and different rate quotas. Use Codestral's free IDE tier for autocomplete and reserve Devstral for agentic edits.

### What does HTTP 429 mean on the Devstral API?

HTTP 429 Too Many Requests means you've exceeded your tier's RPM ceiling. The response includes a Retry-After header specifying how many seconds to wait. Implement exponential backoff (wait = min(2^attempt, 60) seconds ± 10% jitter) and honor that header. On the free tier, the RPM limit is very low; upgrade to pay-as-you-go for meaningful throughput.

### Can I self-host Devstral?

Devstral Small is released as Apache 2.0 open weights, which permits commercial self-hosting at zero per-token cost. This is the open-weight variant of the model family. The full hosted Devstral endpoint on La Plateforme is a managed service. For high-volume, lower-complexity coding tasks, running Devstral Small on your own GPU infrastructure can eliminate per-token costs entirely.

### How does Devstral compare to GPT or Claude for code tasks?

Devstral is purpose-built for agentic code editing — multi-step file modifications, PR generation, and structured edit workflows — with a 256K token context window (per third-party trackers; verify). At approximately $0.30/$0.90 per MTok, it is significantly cheaper than most flagship coding models. The EU Paris routing is a compliance advantage over US-only alternatives.

### Why does Mistral not publish exact RPM limits for Devstral?

Mistral moved away from publishing fixed public RPM tables and now surfaces per-organization limits in Admin Console → Limits. This means your actual ceiling can differ based on account history and usage patterns. The ~300 RPM figure for the paid tier comes from third-party trackers — confirm your specific ceiling in the Admin Console, as it is the authoritative source for your org.
