Claude Opus 4.7 Launches with High-Res Vision but Anthropic Concedes Gap to Unreleased Mythos

Anthropic·medium signal

Anthropic released Claude Opus 4.7 on April 16 with notable gains in advanced software engineering and the first Claude model with high-resolution image support (2576px / 3.75MP max). Pricing stays at $5/$25 per 1M input/output tokens, available across all platforms including Bedrock, Vertex AI, and Microsoft Foundry. However, Anthropic publicly conceded that Opus 4.7 'still falls short' of the Mythos Preview model, which remains limited to a handpicked group of tech and cybersecurity companies — an unusual admission that their public model trails their restricted one.
