The boards re-rank after every run, so the figures here follow the leaderboard: each model’s own page, Claude Opus 4.7 and GPT-6.1 Sol, carry the full history. The whole board for each category is on best LLM for coding, best LLM for reasoning and best AI model for agents.
02
Is Claude Opus 4.7 better than GPT-6.1 Sol for coding?
The Coding board: seven repository debugging tasks graded by running the project’s own tests, including hidden tests the model never sees, re-tested every four hours.
Claude Opus 4.7 scores 93 ± 0.5 — joint 5th of the 24 models on the Coding board in the last 24 hours. GPT-6.1 Sol scores 93 ± 0.8 — joint 5th of the 24 models on the Coding board in the last 24 hours. They score the same: a statistical tie on coding.
Over the last 30 days, Claude Opus 4.7 passed 92% of its coding attempts and GPT-6.1 Sol 91%.

03
Is Claude Opus 4.7 better than GPT-6.1 Sol for reasoning?
The Reasoning board: four long, multi-turn working sessions every day, with continuity checked by running code against rules stated earlier in the session.
Claude Opus 4.7 scores 53 ± 2.5 — joint 20th of the 22 models on the Reasoning board in the last 24 hours. GPT-6.1 Sol scores 58 ± 2.5 — joint 17th of the 22 models on the Reasoning board in the last 24 hours. The gap of 5 points is within the measurement noise, so head to head the two are a statistical tie on reasoning; the board places them apart because a place is set against the leader of the group above, not against the other model.

04
Is Claude Opus 4.7 or GPT-6.1 Sol better for agents and tool calling?
The Tool use board: nine tasks, each in a real sandboxed machine — either the job is done at the end or it is not. Task completion, tool selection, parameter accuracy, efficiency, error handling, context awareness and safety are scored.
Claude Opus 4.7 scores 72 ± 2.5 — joint 20th of the 22 models on the Tool use board in the last 24 hours. GPT-6.1 Sol scores 81 ± 2.5 — joint 14th of the 22 models on the Tool use board in the last 24 hours. The gap of 9 points is beyond the measurement noise, so GPT-6.1 Sol leads on tool use.

05
Which is cheaper, Claude Opus 4.7 or GPT-6.1 Sol?
List prices are each provider’s standard rate per million tokens, cache-miss input and output. Cost per correct answer counts every attempt on the coding tasks, failed ones included, over the last 30 days.
Claude Opus 4.7 lists at $5 in / $25 out per 1M tokens; GPT-6.1 Sol at $2 in / $10 out.
On a 40/60 input–output blend, Claude Opus 4.7 costs about 2.5× as much per token as GPT-6.1 Sol.
Over the last 30 days, 1,000 correct coding answers cost about $14.64 with Claude Opus 4.7 and $6.65 with GPT-6.1 Sol, every attempt billed, failed ones included.
The cheapest model that still passes the tests is on best value AI model.
06
Which is faster, Claude Opus 4.7 or GPT-6.1 Sol?
Median response time of one attempt or one session, from the same runs as the scores, over the last 30 days.
Median response time on the coding tasks over the last 30 days: Claude Opus 4.7 16 s, GPT-6.1 Sol 13 s.
GPT-6.1 Sol answers about 1.3× faster.
On the reasoning sessions 1.9 min against 1.9 min and on the tool-use sessions 1.9 min against 2.1 min (Claude Opus 4.7 first).
Every model’s median is on fastest AI model.
07
Is Claude Opus 4.7 or GPT-6.1 Sol getting worse?
Page-Hinkley change-point detection (a CUSUM-family test) runs per suite on each model’s daily median, with every constant published; a real shift is confirmed over days, not hours. An hourly canary of two fixed coding probes catches sharp drops.
Claude Opus 4.7 is holding steady on the 24-hour board; no Page-Hinkley detection on coding, reasoning or tool use.
GPT-6.1 Sol is holding steady on the 24-hour board; no Page-Hinkley detection on coding, reasoning or tool use.
The family pages answer the question for every model of a provider: Is Claude getting worse? and Is ChatGPT getting worse?. The method is on AI drift detection.

Should I use Claude Opus 4.7 or GPT-6.1 Sol?
Only a difference that clears a threshold counts: a board lead beyond the measurement noise (the leaderboard’s own tie rule), 10% on list price, 20% on response time or cost per correct answer.
Choose GPT-6.1 Sol when
- the work is tool use: it leads the Tool use board by 9 points in the last 24 hours (81 ± 2.5 against 72 ± 2.5)
- price per token matters: it lists at $2 in / $10 out per 1M tokens against $5 in / $25 out
- cost per correct answer matters: about $6.65 per 1,000 correct coding answers against $14.64 over the last 30 days
- response time matters: a median of 13 s on the coding tasks against 16 s over the last 30 days
No difference clears a threshold in favour of Claude Opus 4.7.

Can I route between Claude Opus 4.7 and GPT-6.1 Sol automatically?
One OpenAI-compatible endpoint sends each request to whichever model the boards favour for that kind of work, with your own provider keys.
Yes. The Smart Router is one OpenAI-compatible endpoint with 14 auto-* routing modes: a quality mode such as auto-coding sends each request to the model placing highest on that board, the value modes pick within 5 points of the best and then the cheapest measured cost per run, and auto-split sends traffic by weights you set. Routing is drift-aware by default, uses your own provider keys and adds zero markup on tokens. Free includes 1,000 routed requests a month.
Every mode is described in the router documentation.

How we test Claude Opus 4.7 and GPT-6.1 Sol
Every model on the board runs the same tasks on the same schedule: coding every four hours, reasoning and tool use daily, with an hourly canary probe.
Scores come from our own runs through each provider’s public API, not vendor-reported numbers. Every model gets the same prompts and output budget, and the same sampling settings wherever a provider accepts them, and is graded by executing what it produces. Every score carries a standard error from its own run-to-run repeatability; models whose lead is inside that noise share a place, written joint.
The methodology is public — every weight, statistical test and drift constant. The test tasks are private, so no lab can train on them. The full method, weights and constants are on the methodology page.
