Frontier Model Selector

Model Battle Cards: Western vs Chinese Frontier.

Stop trusting static leaderboard screenshots. Compare Claude, GPT, Gemini, and Chinese models (DeepSeek, Kimi, Qwen, GLM) on task fit, weaknesses, and real blended API costs.

Updated June 2026
â„šī¸
The thesis: stop trusting any single benchmark number you read this week. Standardized leaderboards running models through same-scaffold agent harnesses land 10-12 points below vendor-reported numbers because vendor numbers include custom scaffolding that real users don't have by default. Treat every metric as a directional signal, not a fixed score.

Model Battle Cards

Card 1

Claude

Anthropic
Flagship: Opus 4.8
Mid-Tier: Sonnet
Low-Latency: Haiku
Genuinely Best At

Multi-file engineering accuracy and human-preference writing quality. Holds top position on blind human evaluations. Best for multi-file refactors and resolving ambiguous bug reports.

Honest Weakness

Price. Sits at the top of the cost range. Standard context window is large, but default window is smaller than Gemini's massive baseline.

đŸŽ¯ Pick when: copy/code accuracy is critical
Card 2

GPT

OpenAI
Flagship: GPT-5.5
Ecosystem: Codex, API, Reasoning Tiers
Genuinely Best At

Versatility and autonomous agent tooling. The default for creative range, long background jobs, and CLI-driven coding agents running semi-independently.

Honest Weakness

Priced at or above Claude on most rates, without a clear specialist edge. Reasoning benchmark advantages live in dedicated reasoning lines rather than mainline GPT.

đŸŽ¯ Pick when: task is open-ended with tool loops
Card 3

Gemini

Google
Flagship: Gemini 3.1 Pro
Low-Cost: Flash Tiers
Genuinely Best At

Price-performance and native multimodality. Cheapest Western flagship (~half input/output cost of Claude/GPT). Largest standard context window and best on dense video/audio inputs.

Honest Weakness

Voice. Struggles to produce natural, less "obviously AI" long-form writing. Performs best under structural stress rather than everyday Q&A.

đŸŽ¯ Pick when: running high-volume multimodality
Card 4

Chinese Frontier

DeepSeek, Kimi, Qwen, GLM
Flagship: DeepSeek V4 / Kimi K2.6 / Qwen 3.6 / GLM 5.1
Genuinely Best At

Price-to-capability by a huge margin. DeepSeek's flagship coding tier lands within points of Claude on SWE-bench Verified at 1/10th the cost. Permissive open-weight licenses.

Honest Weakness

English nuance (occasional ESL-pattern artifacts in long text). Compliance restrictions and data provenance make legal approval harder in regulated sectors.

đŸŽ¯ Pick when: cost-scaling or self-hosting internal code

Blended API Cost Calculator

Calculates the cost of a daily workload (based on a realistic split of 70% input tokens and 30% output tokens) using published 2026 rates.

10M

Adjust from 1M to 100M tokens per day.

đŸ“Ĩ 70% Input Tokens  •  📤 30% Output Tokens

Standard split for coding loops where codebases are ingested as context inputs.

Google Gemini Tier
$50/day

Blended rate: ~$2/$12 per million tokens.

Cheapest Western flagship option. Optimized for high-volume context analysis and multimodality.
Claude & GPT Tier
$110/day

Blended rate: ~$5/$25–30 per million tokens.

Premium Western flagships. Sits at the top of the price range but delivers maximum accuracy.
Chinese Frontier Tier
$8/day

Blended rate: ~$0.40–$0.90 per million blended.

Extreme price efficiency. Best for scaling massive internal pipelines and developer agent scripts.
