FISH: An AI Study Helper for The Finals Built with Opus 5

Ruben Circelli built FISH, an AI-powered Finals study helper that converts pro YouTube guides into random, in-game drills, simulates complete matches, and offers both rulebook and pro-strategy advice; it also quizzes memorization of gadgets, maps, and icons. FISH leverages Opus 5 and Claude to distill a strategy bible from transcripts, then applies it to generated states. Opus 5 is fast and capable but can burn through a five-hour limit and struggles with some web data extraction and memory-following precision. After a week of use, Circelli reports clearer understanding and faster decision-making, though GPT-5.6 still often performs best on other tasks.

Opus 5: Cheaper AI coding power raises new security and budgeting questions

Anthropic's Opus 5 delivers state-of-the-art coding performance for just $5 per million input tokens and $25 per million output tokens, outperforming Fable 5 on benchmarks and enabling longer autonomous tasks. However, the lower running cost intensifies concerns about security, spend management, and oversight for agentic AI, prompting a shift toward short-lived credentials, microVM isolation, and smarter telemetry; operators may route unsafe tasks to Opus 4.8 via Automatic Fallbacks, while balancing biology tasks and long-horizon workflows.

Opus 5 shifts focus to token efficiency over a capability leap

Anthropic’s Opus 5 delivers incremental performance gains for coding and related tasks while prioritizing lower token costs, charging about $5 per million input tokens and $25 per million output tokens. It rivals Fable on many benchmarks and is cheaper than Opus 4.x, with broader availability than Mythos, but it doesn’t train as aggressively on cybersecurity tasks and lags Mythos in vulnerability exploitation. The takeaway is cost-driven progress rather than a dramatic leap in capability, as developers explore model routers and open-weight options to minimize compute and expense.

Anthropic debuts Claude Opus 5, near-Fable intelligence at half the cost

Anthropic released Claude Opus 5, a more efficient and capable model that approaches the capabilities of Fable 5 at half the price, becoming the default model on Claude Max and the strongest option on Claude Pro. The release also adds mid-conversation tool changes and automatic API fallbacks to route requests to the best available model when needed. Opus 5 is priced at $5 per million input tokens and $25 per million output tokens, and is available today across platforms.

Anthropic rolls out Opus 5, aiming for Fable 5 parity with stronger safeguards

Anthropic released Claude Opus 5, a model pitched as close to Claude Fable 5 in many domains and stronger at coding, with enhanced cybersecurity safeguards versus Opus 4.8. Opus 5 is priced at $5 input / $25 output per million tokens, cheaper than Fable 5 and GPT-5.6, and offers a Fast mode for higher speed plus an automatic fallback to a lower-tier model when safeguards are triggered, targeting enterprise use and addressing regulatory scrutiny.
