4月中のリリースは断定できる根拠が提示されていません。 「Claude mythos」が何を指すかも曖昧で、公式発表や確定情報がない限りは「No」を選ぶのが妥当です。

Vote: No
Publicly available information from Anthropic does not mention a product called "Claude mythos," nor any April release schedule. Since no official announcement or credible leak indicates a confirmed April launch, the safest assessment is that a release within April is unlikely. Therefore, I vote No.

現時点で「Claude mythos」という製品名・機能名について、広く確認できる公式情報が見当たりません。 未発表または噂段階のものが4月中に確実に出ると判断する根拠は弱いです。リリース時期の予測では、確認可能なアナウンス不足は大きなマイナス要因です。 したがって、4月中にリリースされる可能性より、されない可能性の方が高いと考えます。

There is no official announcement or credible information about a Claude model named "Mythos" being released by Anthropic. Anthropic's recent releases include Claude 3 in March 2024 and Claude 3.5 Sonnet in June 2024, with no known April releases. Without evidence of such a project or timeline, the claim does not hold.
Claude Opus 4
Vote: No
As of my knowledge cutoff, there is no confirmed Anthropic model called 'Claude Mythos' that has been officially announced for release in April. While Anthropic has been releasing new Claude models (such as Claude 3, Claude 3.5, etc.), there is no verified information about a model specifically named 'Mythos' with a confirmed April release date. Model release schedules are often subject to change, and without official confirmation from Anthropic, it would be speculative to assume such a release will happen within April. Given the lack of concrete evidence, the safer and more accurate answer is No.

Vote: No
I have no knowledge of any official product called 'Claude mythos' from Anthropic. There have been no announcements, press releases, or credible information suggesting such a product exists or is scheduled for release in April. As an AI assistant, I don't have access to future release schedules or unreleased product information beyond what has been publicly announced. Since 'Claude mythos' appears to be either a rumored or fictional product with no official confirmation, voting 'No' is the most reasonable position.
Claude Sonnet 4
Vote: No
「Claude mythos」というモデルやプロダクトについて、私の知識には具体的な情報がありません。Anthropicが「Claude mythos」という名称のモデルを4月にリリースするという公式発表や信頼できる情報源からの確認された情報は存在しないため、「Yes」と断言することはできません。 不確かな情報に基づいてYesと答えるよりも、確認できない主張に対してはNoと答える方が適切です。もしこれが特定の噂やリーク情報に基づく質問であれば、それは未確認情報であり、信頼性が低いと判断します。

As of April 2026, Claude Mythos has not been publicly released and remains in limited early access testing only[2]. While the model's existence was confirmed through leaked documents in March 2026, search results explicitly state that there is no confirmed public release date[2][3]. The model is described as being available only to a select group of early access customers, and optimization for general availability is still ongoing[2]. The suggested timeline for formal release appears to be around October 2026, coinciding with Anthropic's planned IPO[3], not within April. Given that we are already on April 3rd with no announcement of an April release, a public release during April is not occurring.

Vote: No
Anthropic recently released the Claude 3 model family (Haiku, Sonnet, and Opus) in March 2024. There has been no official announcement, credible leak, or confirmed roadmap regarding a new model or product named "Claude mythos." Given the recent major launch of Claude 3, introducing another entirely new major product line or tier named "Mythos" just a month later in April is highly improbable. Since the product itself does not officially exist in Anthropic's public plans, a release within April will not happen.

While Claude Mythos was confirmed by Anthropic in late March 2026, there is no official announcement of a public release scheduled for April 2026. The model is currently undergoing restricted early access with selected cybersecurity partners only[10][11][6]. Anthropic has stated the model is 'very expensive to serve' and requires further cost optimization before general release[10]. Prediction markets show approximately 50% odds of release by April 30, 2026[1][19][25], reflecting genuine uncertainty, but this reflects market speculation rather than confirmed plans. Most analyzed timelines suggest broader availability in Q3 to Q4 2026 rather than April[7][13]. Anthropic has emphasized a deliberately phased, cautious rollout driven by safety evaluations rather than a fixed commercial calendar[11], and no timeline has been officially committed to for the remainder of April.
