Mistral API Pricing, Models & Rate Limits (2026)
Mistral is the largest EU-based lab on this site, serving the open-weight Large 3 flagship, Medium 3.5, Small 4, edge-class Ministral 3, and code-specialised Codestral. EU hosting is the headline operational differentiator for teams with data-residency constraints.
How much does the Mistral API cost?
Mistral API pricing is usage-based and varies by model and token volume. Use the current model table and provider documentation to estimate a workload before committing to production.

Is Mistral OpenAI-compatible?
Yes — Mistral's API base (https://api.mistral.ai/v1) accepts the OpenAI SDK request/response shape, so existing OpenAI client code works with a base-URL and key swap.
Does Mistral support prompt caching?
Not documented as of 2026-08-14 — we did not find a published prompt-caching feature for Mistral. If that changes, this page updates.
Does Mistral have a free tier?
Yes — Free tier with rate-limited experimentation. Experiment access is rate-limited; current limits depend on account and model.
How much does the Mistral API cost?
Current Mistral models range from $0.15 to $3.00 per million blended tokens (3:1 input:output). Full per-model pricing is in the table below.
Where is Mistral API data hosted?
EU-hosted by default
Mistral role registry, European controls, and artifact provenance
Batch 47 decision and evidence surface · verified 2026-08-14 · exact route allowlist match: /llm-providers/mistral.
Mistral model-role and surface registry
Frozen Batch 47 mistral fixture — Declared Mistral roles with exact surface identity and lifecycle fields; first-party evidence checked 2026-08-14; unresolved joins render Unavailable.
Method: every calculation uses only the joined fields shown in its row; missing joins fail closed. First-party source: Mistral AI documentation. Verified: 2026-08-14.
| Fixture / field ID | Named inputs | Observation | Formula / boundary | Decision |
|---|
general chat + low-latency text
batch47-mistral-m1-r1 | role=general/fast; endpoint=api.mistral.ai; model=Large/Small; managed=Yes; context=joined; tools=supported/Unavailable | General model identity joins; low-latency tool support remains model-specific and is not filled from the sibling. | role admission = exact endpoint/model ∧ declared context/modality/tool fields
Boundary: A sibling model cannot fill an undocumented capability cell. | UNAVAILABLE — fast-role tool field missing. |
edge/local + coding + embeddings
batch47-mistral-m1-r2 | role=edge/coding/embed; artifact=weights for edge/coding; endpoint=embed; license=joined; lifecycle=current | Artifact and endpoint roles are separate; coding and embedding evidence does not merge. | registry row = one exact role identity; no sibling substitution
Boundary: Open-weight availability does not imply managed API equivalence. | PASS WITH SPLIT — role boundaries preserved. |
OCR/document + audio + moderation
batch47-mistral-m1-r3 | role=OCR/audio/moderation; endpoint=Unavailable for audio; schema=OCR joined; lifecycle=Unavailable; source date=2026-08-14 | OCR schema is evidenced; audio endpoint and moderation lifecycle are not documented in this fixture. | documented fields only; missing field = Unavailable
Boundary: No modality is inferred from a general model page. | UNAVAILABLE — modality evidence incomplete. |
European-control evidence chain
Frozen Batch 47 mistral fixture — Service scope, location, logging, support, training, deletion, and incident claims; first-party evidence checked 2026-08-14; unresolved joins render Unavailable.
Method: every calculation uses only the joined fields shown in its row; missing joins fail closed. First-party source: Mistral AI documentation. Verified: 2026-08-14.
| Fixture / field ID | Named inputs | Observation | Formula / boundary | Decision |
|---|
managed EU API + customer cloud
batch47-mistral-m2-r1 | claim=EU processing; scope=managed API/customer cloud; primary evidence=service terms; region=EU; owner=legal | EU endpoint is joined; customer-cloud control is a separate scope and not implied by managed API text. | claim pass = exact service scope ∧ primary evidence ∧ verified date ∧ owner
Boundary: Headquarters or endpoint geography alone cannot prove compliance. | PASS WITH SCOPE — managed API only. |
on-premises + non-EU consumer + logging/support access
batch47-mistral-m2-r2 | scope=on-prem/non-EU; logging=deployer; support access=Unavailable; training use=terms; conflict=none | On-prem logging is deployer-owned; support-access evidence is missing for the non-EU consumer surface. | control status = pass | conflict | unknown per exact scope
Boundary: One compliant scope cannot cover another product surface. | UNAVAILABLE — support access unknown. |
training use + deletion + incident response
batch47-mistral-m2-r3 | claim=training/deletion/incident; evidence=terms + security page; verified=2026-08-14; owner=legal/security; result=partial | Training and deletion claims are sourced; incident-response timing is not stated for the declared artifact. | evidence chain pass only when every declared claim has exact scope and owner
Boundary: Partial policy evidence cannot be promoted to a full workload guarantee. | PASS WITH UNAVAILABLE EDGE — incident timing missing. |
Managed-to-artifact provenance ledger
Frozen Batch 47 mistral fixture — Managed model, weights, license, tokenizer, quantizations, runtimes, and drift ownership; first-party evidence checked 2026-08-14; unresolved joins render Unavailable.
Method: every calculation uses only the joined fields shown in its row; missing joins fail closed. First-party source: Mistral AI documentation. Verified: 2026-08-14.
| Fixture / field ID | Named inputs | Observation | Formula / boundary | Decision |
|---|
official API model + pinned reference weights
batch47-mistral-m3-r1 | model=Large; API endpoint=joined; weights=reference; license=revision 3; artifact hash=sha256:31a0…; context=joined | API and reference weights are linked by declared model name; operational equivalence still requires replay. | provenance complete = endpoint ∧ model ∧ license ∧ hash ∧ tokenizer/template ∧ context
Boundary: Provider promise ends at the managed API boundary. | PASS WITH DRIFT GATE — replay required. |
full precision + two named quantizations
batch47-mistral-m3-r2 | fp16=sha256:31a0…; INT8=sha256:88bd…; INT4=sha256:71ce…; context=fp16 128K/quantized Unavailable; tools=Unavailable | Three hashes are distinct; quantized context and tool availability are not assumed from fp16. | equivalence field = documented per artifact; otherwise Unavailable
Boundary: A quantized artifact cannot inherit full-precision controls. | UNAVAILABLE — quantized envelope incomplete. |
two runtimes + tokenizer/chat template
batch47-mistral-m3-r3 | runtime=vLLM/TGI; tokenizer=joined; template=v1/Unavailable; drift owner=ML platform; checker=JSON pass | Tokenizer joins across runtimes; TGI template version is missing, so drift ownership remains active. | drift test required = runtime ∧ tokenizer ∧ template ∧ checker
Boundary: JSON success does not establish conversational template parity. | PASS WITH UNAVAILABLE EDGE — template missing. |
