TheAI Daily Signal

Every source. One signal. The day in artificial intelligence, distilled into plain English.

Model tracker

The leading models compared on independent benchmarks — intelligence, evals, price and speed — refreshed every morning, with day-on-day movement and the longer trend.

Editor's notes: the top five in practice

Claude Fable 5 (Adaptive Reasoning, Max Effort)

Best for: the hardest problems, when quality outranks everything.

The leader on nearly every measure we track — intelligence (64.9), agentic tool use (tau², 0.99), autonomous terminal work, and the punishing Humanity's Last Exam — but it makes you pay twice for it: roughly double the price of its rivals ($10 in / $50 out per million tokens) and over a minute before the first word arrives at this effort setting. A deep-work specialist, not a conversation partner. Worth noting: independent testers have rated its everyday coding more modestly than its benchmark scores suggest — see our 12 June transmission.

Claude Opus 4.8 (Adaptive Reasoning, Max Effort)

Best for: production agents.

The balance point of the field: second-best agentic scores (tau² 0.94), half Fable's price ($5 / $25), and a 19-second start instead of a minute. If you are building systems that browse, call tools and work unattended, this is where capability per pound currently peaks.

GPT-5.5 (xhigh)

Best for: research, analysis and long documents.

The top scorer on graduate-level science questions (GPQA 0.935) and on long-context reasoning — the measure that matters when you feed a model a 200-page report. Strong second on coding. Slow to start (~45 seconds), so suited to considered work rather than quick exchanges.

GPT-5.5 (high)

Best for: interactive development.

Nearly all of xhigh's ability at the same price, with the wait cut to about 14 seconds — the difference between a coding assistant you talk to and one you queue for. The sensible default in the GPT-5.5 family unless you need the last benchmark point.

Claude Opus 4.7 (Adaptive Reasoning, Max Effort)

Best for: proven, role-specific deployments.

A step behind its successor on every measure, at the same price — but the fastest first response of the five (under 11 seconds) and months of production track record. The conservative choice for customer-facing assistants and established workflows that prize predictability over peak scores.
