Although Claude Opus 4.5 showed strengthened safety boundaries in many ambiguous contexts compared to Claude Opus 4.1, the new model still showed areas for continued improvement. These areas include, for example, calibrating on highly dual-use cyber-related exchanges where the model can sometimes be overly cautious, distinguishing between legitimate and potentially harmful requests for targeted content generation, or handling ambiguous conversations related to suicide and self-harm in certain contexts. This is generally consistent with patterns we’ve observed for past models and have been act…

It could try to spread its misaligned objectives to other Claude Code sessions, but the communication channels available to it (editing and pushing code, sending internal messages, asking users to post content on social media on its behalf, etc.) are plain-text channels that are monitored (by automatic monitoring or informally by employees). Therefore, if a large piece of misalignment-relevant information spreads to hundreds of instances over a few days, it is likely (for deployments with safeguards similar to the ones described above) that at least some human…

Coding benchmarks favor Opus 4.7 clearly. Image by Author. SWE-bench has several variants and both vendors highlighted the one where they perform best. Anthropic applied memorization screens and reports that Opus 4.7's margin holds after excluding flagged problems. Worth context: Z.ai's open-weight GLM-5.1 briefly led SWE-bench Pro at 58.4% in early April 2026 before Opus 4.7's 64.3% arrived, so any "state of the art" claim here has a short shelf life. ### Agent and computer-use benchmarks With Opus 4.7's release, Anthropic published comparison numbers for both models across most agentic benc…

At a spec level, Opus 4.7 is positioned as Anthropic’s most capable generally available model for coding, enterprise workflows, multimodal reasoning, financial analysis, life sciences, cybersecurity, and long-running agentic work. It supports a 1M context window with no long-context pricing premium, up to 128K output tokens, and standard Opus pricing at $5 per million input tokens and $25 per million output tokens. The model's reliable knowledge cutoff is January 2026. [...] ## Same Price, Different Token Economics The first thing to understand about Opus 4.7 is that list pricing is unchanged…

What changed in Opus 4.7 besides pricing dynamics? SWE-bench Pro jumped from 53.4% to 64.3%, CursorBench from 58% to 70%, vision resolution tripled to 3.75 MP, and long-context retrieval improved. Context window stays at 1M tokens. ## The Bottom Line Anthropic kept the rate card stable on purpose, and that is a gift to anyone building a budget. But “pricing unchanged” is not the same as “cost unchanged.” The 35% tokenizer ceiling is the real pricing story for Opus 4.7. Measure it on your own traffic before you migrate, lean hard on caching and batch to claw back the difference, and be hon…
What is the official Claude Opus 4.7 API price? Anthropic's model overview lists Claude Opus 4.7 at

$25 / MTok
output, with separate pricing considerations for caching and batch processing. ### Did Claude Opus 4.7 change token usage? Yes. Anthropic's docs say the new tokenizer can use about 1x to 1.35x more tokens than earlier models depending on content, so migration should include real traffic testing. ### Can I still set temperature or top_p on Claude Opus 4.7? Not in the old way. Anthropic's Claude 4.7 docs say setting temperature, top_p, or top_k to…
Claude Opus 4.7 pricing: same list price, different cost conversation The pricing headline is easy to remember: $5 per million input tokens and $25 per million output tokens, the same posted rate as Opus 4.6. That is good news in one narrow sense. Teams do not need to rework every budget model just because Anthropic raised list prices. But treating that as the full pricing story would be a mistake. [...] ## Context window, output limits, and long-running work One reason Opus 4.7 is getting attention is that Anthropic positions it for long-horizon work rather than short exchanges. The model…
Additionally, the model "thinks more at higher effort levels," generating more output tokens during reasoning. At xhigh or max, Anthropic recommends setting max_tokens to at least 64K as a starting point. ## What's Unchanged Context window: 1M tokens, same as Opus 4.6, no long-context premium Output limit: 128K tokens per response Adaptive thinking and Agent Teams: both carry forward Prompt caching: up to 90% cost reduction on cached content Pricing structure: $5/$25 per million tokens across all platforms One notable removal: prefilling assistant messages now returns a 400 error on Opu…

Although Claude Opus 4.5 showed strengthened safety boundaries in many ambiguous contexts compared to Claude Opus 4.1, the new model still showed areas for continued improvement. These areas include, for example, calibrating on highly dual-use cyber-related exchanges where the model can sometimes be overly cautious, distinguishing between legitimate and potentially harmful requests for targeted content generation, or handling ambiguous conversations related to suicide and self-harm in certain contexts. This is generally consistent with patterns we’ve observed for past models and have been act…

Coding benchmarks favor Opus 4.7 clearly. Image by Author. SWE-bench has several variants and both vendors highlighted the one where they perform best. Anthropic applied memorization screens and reports that Opus 4.7's margin holds after excluding flagged problems. Worth context: Z.ai's open-weight GLM-5.1 briefly led SWE-bench Pro at 58.4% in early April 2026 before Opus 4.7's 64.3% arrived, so any "state of the art" claim here has a short shelf life. ### Agent and computer-use benchmarks With Opus 4.7's release, Anthropic published comparison numbers for both models across most agentic benc…

The improvements stand out most in agentic coding, computer use, knowledge work, and early scientific research, areas where progress depends on reasoning across context and taking action over time. GPT-5.5 delivers that increase in capability without giving up speed. Larger and more capable models are often slower, but GPT-5.5 matches GPT-5.4 on per-token latency in real-world serving while operating at a higher level overall. It also uses significantly fewer tokens to complete the same Codex tasks, which makes it more efficient as well as more capable. The gains are especially clear in agent…

What changed in Opus 4.7 besides pricing dynamics? SWE-bench Pro jumped from 53.4% to 64.3%, CursorBench from 58% to 70%, vision resolution tripled to 3.75 MP, and long-context retrieval improved. Context window stays at 1M tokens. ## The Bottom Line Anthropic kept the rate card stable on purpose, and that is a gift to anyone building a budget. But “pricing unchanged” is not the same as “cost unchanged.” The 35% tokenizer ceiling is the real pricing story for Opus 4.7. Measure it on your own traffic before you migrate, lean hard on caching and batch to claw back the difference, and be hon…

output, with separate pricing considerations for caching and batch processing. ### Did Claude Opus 4.7 change token usage? Yes. Anthropic's docs say the new tokenizer can use about 1x to 1.35x more tokens than earlier models depending on content, so migration should include real traffic testing. ### Can I still set temperature or top_p on Claude Opus 4.7? Not in the old way. Anthropic's Claude 4.7 docs say setting temperature, top_p, or top_k to…
Claude Opus 4.7 pricing: same list price, different cost conversation The pricing headline is easy to remember: $5 per million input tokens and $25 per million output tokens, the same posted rate as Opus 4.6. That is good news in one narrow sense. Teams do not need to rework every budget model just because Anthropic raised list prices. But treating that as the full pricing story would be a mistake. [...] ## Context window, output limits, and long-running work One reason Opus 4.7 is getting attention is that Anthropic positions it for long-horizon work rather than short exchanges. The model…
Additionally, the model "thinks more at higher effort levels," generating more output tokens during reasoning. At xhigh or max, Anthropic recommends setting max_tokens to at least 64K as a starting point. ## What's Unchanged Context window: 1M tokens, same as Opus 4.6, no long-context premium Output limit: 128K tokens per response Adaptive thinking and Agent Teams: both carry forward Prompt caching: up to 90% cost reduction on cached content Pricing structure: $5/$25 per million tokens across all platforms One notable removal: prefilling assistant messages now returns a 400 error on Opu…
