## 🔥 Currently Recommended Models

The following are currently stably supplied popular models. For the complete model list and real-time pricing, visit the [APIYI Console Pricing Page](https://www.apiyi.com/account/pricing) or the on-site [Model Pricing Overview](/en/models).

<Warning>
  **Model Upgrade Recommendations**:  We recommend using the latest models for best performance, but please note:

  1. **Initial instability is common**: Newly launched models may experience slow responses, timeouts, or occasional errors due to limited compute capacity at the vendor — this typically stabilizes within days to weeks
  2. **Check parameter compatibility**: New models may introduce or change parameters (e.g., `max_completion_tokens` replacing `max_tokens`). Before upgrading, verify that your API parameters remain compatible with older models
  3. **Always test before going live**: Before deploying a new model to production, thoroughly validate it in a test environment to ensure output quality and API compatibility meet expectations
</Warning>

<Info>
  A "—" in the context column means the vendor has not published a definitive figure; refer to the console and official documentation. All prices are per 1M tokens (input/output) and can be combined with top-up bonuses.

## Model Categories

### 🤖 OpenAI Series

#### 🆕 Latest Models

| Model Name | Model ID | Context Length | Features | Recommended Scenarios |
| - | - | - | - | - |
| **GPT-6 Astra** 🔥 | `gpt-6-astra` | 1.05M | 6-gen flagship built for computer use and long-horizon agents; five reasoning-effort tiers (adds `xhigh` / `max`), Terminal-Bench 4.0 **57.9%**, ScreenSpot-Pro 92.7%; \$10/\$50 | Top-tier agents, computer use, research |
| **GPT-6 Sol** 🔥 | `gpt-6-sol` | 1.05M | 6-gen mid tier at roughly half the price of 5.6 Sol (a long-term price, not a promo), 128K output; \$2/\$10 | Building features, code review, data analysis |
| **GPT-6 Luna** 🔥 | `gpt-6-luna` | 1.05M | 6-gen lightweight tier, \$0.10/\$0.50, for summarization, extraction and other bulk work | High concurrency, cost-sensitive |
| **GPT-5.5 Pro** | `gpt-5.5-pro` | 1M | Deep-reasoning specialist, Terminal-Bench 2.0 82.7%; **`/v1/responses` endpoint + SVIP group only**, very expensive | Top-tier reasoning, research |
| **chat-latest** | `chat-latest` | 400K | Version-less alias, always points to the latest ChatGPT Instant model | Quick writing, conversation |

<Note>
  **GPT-6 series supply**: the `default` / `svip` official-relay groups match official pricing on all four billing items, and both Chat Completions and Responses are tested working (including function calling) — migrating from 5.6 only needs the `model` field changed. Astra is also available in the `Codex_Reverse` group at a 0.5 discount. For Sol / Luna, a single request above 272K context is billed entirely at the higher tier. See the [GPT-6 Astra launch notes](/en/news/gpt-6-astra-launch) and [GPT-6 Sol / Luna launch notes](/en/news/gpt-6-sol-luna-launch).
</Note>

<Warning>
  **GPT Pro series (e.g. `gpt-5.5-pro`, `gpt-5.4-pro`) usage notes**:

  1. **`/v1/responses` endpoint only**: cannot use `/v1/chat/completions` — switch your SDK / code to the Responses API before calling
  2. **Very expensive**: a single call may cost several dollars, and it is open to the SVIP group only to prevent accidental use on the Default group
  3. **Not recommended for non-professional needs**: use GPT-6 Sol or GPT-5.6 Sol for everyday tasks; Pro suits only research and top-tier work demanding extreme reasoning depth
</Warning>

<Warning>
  **Breaking changes in Opus 5.5 / Fable 5.1**: forced tool calls (`tool_choice` of `any` / `tool`) return 400, thinking blocks are bound to the model, and editing history invalidates thinking blocks. Opus 5.5 additionally **cannot turn thinking off**, and its default effort drops from `high` to `medium`. Read the [Opus 5.5 launch notes](/en/news/claude-opus-5-5-launch) and [Fable 5.1 launch notes](/en/news/claude-fable-5-1-launch) before migrating.
</Warning>

<Warning>
  **30-day data retention compliance for Fable 5 / Fable 5.1 / Mythos 5**: because of these models' advanced capabilities, Bedrock and Anthropic run additional checks for high-risk misuse. For these two models, **inputs and outputs are retained for 30 days** to detect serious abuse — accessed by automated safety systems by default, with human review only when a potential harm is flagged. Retention happens on the AWS / Anthropic side; APIYI is a pure transparent proxy and retains nothing itself. **Other Claude models are unaffected.** See the [Fable 5.1 launch notes](/en/news/claude-fable-5-1-launch).

* Note: some models switch to a higher billing tier past a threshold (Grok 4.5 / 4.6 / 4.7 above 200K, GPT-6 Sol / Luna above 272K, MiniMax-M3 above 512K) — estimate costs before long jobs

**Image Generation**

* Latest recommendation: gpt-image-2.5-flare / gpt-image-2.5-sunburst (live Sep 2026, native 4K, precise size/quality control, same price as gpt-image-2, faster / more precise editing respectively), Nano Banana Pro (4K HD, best text rendering)
* High cost-performance: Nano Banana 2 (\$0.055/image, from \$0.025 pay-as-you-go), Nano Banana Lite (\~4s per image, \$0.025/image)
* Professional design: Seedream 5.0 Pro (\$0.12/call, interactive editing + up to 10 reference images), Seedream 5.0 Lite (\$0.035/image)
* Fast generation: Seedream 5.0 Flash (live Sep 2026, \$0.018/image, 15–20s per image, accurate Chinese typography)
* Cheapest: gpt-image-2-all (reverse channel, \$0.03/image)

* Official relay first choice: VEO 3.1 Official (\$0.3 / \$1.2 per call, 4/6/8s, native synced audio)
* Chinese-vendor workhorses: Seedance 2.5 and 2.0 series (2.5 / standard / fast / mini), Wan2.7, HappyHorse 1.1
* Note: the Sora 2 channels have been retired — use the options above. See [Image & Video Generation Models](/en/api-capabilities/image-video-models)

**Web Search**

* Native web access: Grok 4 All, Grok 3 All (no tool call needed)
* Search grounding: Gemini 3.8 Flash / 3.7 Flash / 3.6 Flash / 3.5 Flash-Lite

### Cost Optimization Recommendations

1. **Tiered Usage**: Use cheaper models for simple tasks, advanced models for complex tasks
2. **Test Optimization**: Test with small models first, use large models after determining needs
3. **Batch Processing**: Choose Luna / Lite / Mini tiers for large volumes of similar tasks
4. **Cache Reuse**: Lean on each vendor's context cache (Kimi K3, Seed 2.1 Turbo and the Claude series bill cached input as low as 1/10)
5. **Turn off unneeded thinking**: some models think by default (Seed 2.1 Turbo, the Gemini Flash series, Qwen3.8-Max) — disabling it for short high-frequency Q\&A saves both money and time
