What was released?
According to the model card on Hugging Face, “DeepSeek-V4.1-Flash-1017” is a minor update of V4.1-Flash, with progress in reasoning, coding, agent tasks and visual tasks. MarkTechPost says it was released on 17 October.
By how much does it improve? (company figures)
The card’s table compares with the previous version: DeepSWE v1.1 77.0 (against 74.2), Terminal-Bench 4.0 42.3 (against 31.2), HLE without tools 42.6 (against 36.8). Other models appear in the table, but the evaluation conditions differ: avoid drawing conclusions from the ranking alone.
Licence and use
The repository and the model weights are under the MIT licence. The card recommends a context of 1 million tokens and a max_tokens of at least 256 K. It does not describe API pricing. The page says no inference provider is deploying it for now.
To keep in mind
The scores are published by DeepSeek itself and have not been verified by third parties. Points not mentioned in the card, such as the number of parameters, are not covered here.
Why follow this?
When an AI model’s “weights” are published, researchers and companies can run it in their own environment and study it. Here, the card states an MIT licence, which is very permissive. But, at the time of the article, no inference provider deploys it on the page, and the scores are DeepSeek’s own.

01The present indicative
est / sont + attribute (noun, adjective, prepositional phrase)
Selon la fiche du modèle, le raisonnement et le code progressent ; la licence est MIT.Key pointsÊtre in the present is est for a singular subject and sont for a plural one. It describes nature, state or place (“is”, “is located”). If what follows (the attribute) is a noun, adjective or prepositional phrase, it is not a passive. If a past participle follows, it is a passive (est annoncé). Headlines and summaries often use the present to describe the current situation.
02The passé composé
present of avoir + past participle
DeepSeek a publié sur Hugging Face une mise à jour de V4.1-Flash.Key pointsThe passé composé is the most common past tense, used for “did” and “has done” — actions completed in the past. It is formed with the auxiliary avoir (a / ont…) in the present + a past participle. Past participles of -er verbs end in -é (annoncer → annoncé); learn the irregular ones (faire → fait, prendre → pris, voir → vu). In the negative, ne … pas wraps the auxiliary (n’a pas annoncé). In the news it reports facts that have already happened, such as “announced” or “voted”.
03The passive voice in the present
être (est / sont) + past participle (+ par / de)
Les scores sont publiés par DeepSeek elle-même et n’ont pas été vérifiés par des tiers.Key pointsThe passive means “is done” or “is being done”. It is formed with être + past participle, which agrees with the subject in gender and number (la mesure est adoptée / les mesures sont adoptées). The agent is introduced by par (or de). In the news it is common when the event, rather than the actor, is the focus (est prévu / est annoncé / est connu).
04The passive in the passé composé
a / ont été + past participle
Qu’est-ce qui a été publié ?Key pointsThe past passive means “was done”. Its form is present of avoir + été (past participle of être) + past participle. Été does not change, but the last participle agrees with the subject in gender and number (la loi a été votée / les textes ont été votés). It is frequent in news reporting results such as votes, decisions and announcements.
05The imperative
present vous form (-ez) / nous (-ons) / tu
D’autres modèles figurent dans le tableau, mais les conditions d’évaluation diffèrent : évitez de conclure à partir du seul classement.Key pointsThe imperative expresses commands, requests and advice. It has no subject: the sentence starts with the verb (Consultez les informations.). The vous form ends in -ez, nous in -ons (Restons prudents.), and tu in -e for -er verbs (Consulte). It is very common in notices and warnings (Vérifiez, Consultez, Restez informé).
06Negation and its scope
ne / n’ … pas · ne … plus
Elle ne décrit pas les tarifs de l’API.Key pointsNormally ne and pas wrap the verb. Before a vowel, ne becomes n’. Check which part of the sentence the negation covers. Ne … plus means “no longer”.
07Citing a source with selon
selon + noun / organisation
Selon la fiche du modèle, le raisonnement et le code progressent ; la licence est MIT.Key pointsSelon means “according to”. Put a person or organisation after it as the source. It separates facts the writer checked directly from what another body or report said. Citing a source does not turn a forecast into an accomplished fact.
08Pouvoir: ability and possibility
peut / peuvent / pourrait + infinitive
Quand les « poids » d’un modèle d’IA sont publiés, chercheurs et entreprises peuvent l’exécuter dans leur propre environnement et l’étudier.Key pointsPut a base-form verb after pouvoir. Peut means “can” or “may”; the conditional pourrait gives a more reserved possibility, “might”. It does not necessarily mean implementation is settled.

Understand the structure and usage from the text.
01Citing a source: によると
noun + によると
モデルカードによると、推論やコード生成などの結果が改善し、ライセンスはMITです。Key pointsAs in “LCPによると”, it shows where the information comes from. What that source reported follows. It is used differently from “私にとって”, which gives one’s own opinion.
02Polite negation and plain form
〜ではありません / 〜ではない
第三者による検証ではありません。Key pointsThey negate a noun and similar content. “ではありません” is the polite form and “ではない” the plain form. “成立ではありません” shows that it cannot be said to have been concluded.
03Giving examples with など
noun / expression + など
推論、コード生成、エージェント作業、画像を使う課題などの評価で、結果が良くなったと説明されています。Key points“暴言など” gives “abusive language” as one example. It is not necessarily a closed list of only the things named. It also helps when reading the scope of a news story.
04The polite past ました
verb stem (連用形) + ました
DeepSeekは、モデル「V4.1-Flash」の更新版を、Hugging Faceで公開しました。Key pointsIn “発表しました”, ました makes a verb polite past. The negative is “ませんでした”. Read the actual date together with the date and time in the text.
05Quoting with と: content and report
plain-form sentence + と + verbe de parole (報じる, 説明する…)
MarkTechPostは、17日に公開されたと伝えています。Key pointsと takes the content that is reported or explained. In “改定する方針だと報じました”, “改定する方針だ” is what the report said. Separating the content from who said it and how makes long sentences easier to read.
06Treating a clause like a noun with こと
plain-form sentence + こと + particle
今回は、ライセンスがMITで、利用や改変の自由度が高いことが、モデルカードに書かれています。Key points“〜すること” treats an action or content like a noun. The particle after it (が・を・は…) shows its role in the sentence. “ことができる” is a fixed combination meaning “can”.
